Salesforce Email Integration: Every Way to Sync Email to Salesforce

If your sales team lives in Gmail or Outlook while your customer data lives in Salesforce, there is a basic problem:

Your customer conversations are happening somewhere your CRM cannot automatically see them.

Emails are sent. Replies come in. New stakeholders get added to threads. Opportunities move forward through conversations that may never make it into Salesforce.

And when those interactions aren’t captured, Salesforce doesn’t just have less activity data.

This displays an incomplete picture of the customer.

That affects sales managers trying to inspect deals, RevOps teams trying to measure engagement, marketers trying to understand account activity, customer success teams trying to understand relationships, and increasingly, AI systems trying to reason over Salesforce data.

The good news is that there are several ways to get email into Salesforce in 2026. The bad news is that salesforce email integration can mean very different things depending on the approach you choose.

You can:

Log emails manually
Use Salesforce’s Outlook or Gmail integration
Use Einstein Activity Capture (EAC)
Use a sales engagement platform
Use a dedicated email/activity capture platform

Each solves a different problem.

Some simply help a rep log an email. Others automatically capture email activity.

And the most sophisticated options go further, turning that activity into structured CRM data about contacts, opportunities, buying groups and relationships.

This guide explains the differences.

What is Salesforce Email Integration?

A Salesforce email integration connects your email system (typically Microsoft Outlook or Google Gmail) with Salesforce so that email activity can be associated with CRM records.

Depending on the solution, that can mean very different things.

A basic integration might let a salesperson:

View Salesforce records from Gmail or Outlook
Create Salesforce records from their inbox
Manually relate an email to an opportunity
Log an email to a contact
View Salesforce information while composing an email

A more advanced email sync solution can automatically capture incoming and outgoing messages and associate them with Salesforce records without requiring the salesperson to manually log anything.

Salesforce’s own Outlook and Gmail integrations provide the in-email experience. Einstein Activity Capture adds automatic activity capture and synchronization.

And dedicated activity-capture platforms can go further by turning email and meeting activity into structured revenue intelligence.

So before choosing a tool, ask this: Do we want Salesforce to help reps log email, or do we want Salesforce to automatically know what is happening in customer relationships?

Those are not the same requirement.

5 Ways to Get Email Into Salesforce

Here’s the simplest way to understand the landscape:

Approach	How email gets into Salesforce	Rep effort	Best for	Biggest limitation
Manual logging	Rep logs each email	High	Small teams / occasional activity	Depends on rep compliance
Outlook/Gmail integration	Rep relates email from inbox	Medium	Working with Salesforce from email	Still relies heavily on user action
Einstein Activity Capture	Automatically captures email	Low	Salesforce-native activity capture	Matching, aliases, complex orgs and storage require consideration
Sales engagement platform	Captures engagement as part of prospecting	Low	SDR/BDR outbound motions	Optimized for engagement, not necessarily complete CRM activity
Dedicated activity capture	Automatically captures and structures activity	Very low	Enterprise revenue teams	Additional platform and cost

The right answer depends less on “Can this tool sync email?” and more on “What do we need Salesforce to know about our customer relationships?”

Let’s look at each option.

1. Manual Email Logging in Salesforce

The simplest Salesforce email integration is no integration at all. A salesperson sends an email from Gmail or Outlook and manually logs it to Salesforce.

Salesforce supports manual email logging through its email tools, including the ability to relate emails to Salesforce records. Enhanced Email also allows emails to be stored as EmailMessage records rather than simply appearing as generic tasks.

How it works

A typical workflow looks like this:

Send email → choose Salesforce record → click Log Email → Salesforce records the activity

The rep decides where the email belongs.

That might be a contact, lead, account, opportunity, case or another Salesforce record that supports activities.

What manual logging does well

Manual logging has one major advantage: Control. The rep decides exactly what belongs in Salesforce.

It can also be inexpensive because you’re using functionality already available within Salesforce rather than introducing another platform.

Manual logging may be enough for organizations that have small sales teams, low email volume, simple sales processes, strong CRM discipline or limited need for historical activity.

Where manual email logging breaks

The problem is not whether Salesforce can log the email. The problem is whether people will consistently do it.

Consider a salesperson handling 80 customer emails a day. If logging each message takes even a few seconds, the process becomes tedious. More importantly, it introduces human judgment into the CRM data:

What did the rep remember to log?
What did they forget?
Which record did they choose?
Did they log the reply?
Did they add the new stakeholder they were emailing?

There are also hard limits to some manual methods. For example, Salesforce’s Email to Salesforce functionality can match up to 50 email addresses and can create up to 50 email activities for a received email; email text and HTML are truncated at 131 KB.

Best use case: Small teams that need occasional email logging and don’t need automatic capture.

Verdict: Inexpensive, simple and controllable, but fundamentally dependent on rep behavior.

2. Salesforce Outlook and Gmail Integrations

The next level is Salesforce’s native integrations with Microsoft Outlook and Gmail.

This is where the phrase Salesforce email integration can become confusing.

The Outlook/Gmail integration is primarily about bringing Salesforce into the rep’s inbox.

Salesforce describes the integration as a way for reps to view, edit and create Salesforce records from their email environment and relate emails and events to Salesforce records.

The Outlook integration is available as a Salesforce add-in through Microsoft AppSource, while the Gmail integration is available through Salesforce’s Chrome-based experience.

What the Outlook/Gmail integration can do

Depending on configuration and licensing, reps can:

See Salesforce records while working in email
Search Salesforce records
Relate emails to Salesforce records
Log emails and events
Create contacts and leads
Create other Salesforce records
View Salesforce information alongside emails
Use email templates
Access productivity functionality

Salesforce’s current documentation also confirms that the integrations can log emails and events to records created from custom objects when those objects support activities.

And Salesforce continues to update the matching and search behavior.

For example, a June 2026 Salesforce knowledge article explains that Outlook and Gmail integrations automatically search email addresses in the From, To and CC fields and can return records across Salesforce objects with Activity Timeline enabled.

The important distinction: Integration does not mean automatic capture

Installing the Outlook or Gmail integration does not automatically mean every customer email is being captured into Salesforce.

Salesforce explicitly points admins toward Einstein Activity Capture when they want emails to be automatically logged to related Salesforce records.

Think of it this way:

Outlook/Gmail Integration

“Let the rep work with Salesforce from their inbox.”

Einstein Activity Capture

“Automatically capture the activity happening in that inbox.”

You can use them together.

Pros:

Native Salesforce experience
Familiar Gmail/Outlook workflow
No separate third-party capture platform required
Useful for record lookup
Useful for manually relating emails
Can support custom-object records when activity tracking is enabled
Admins can customize the email application pane

Cons:

The biggest limitation is behavioral.

If your process depends on the rep clicking Log Email, you’re still depending on rep compliance.

There are also enterprise edge cases to evaluate:

Shared mailboxes
Multiple email identities
Email aliases
Multiple opportunities at the same account
Complex record matching
Historical activity
Duplicate logging
Large-scale activity capture

Salesforce itself documents that automatic search and matching is based heavily on email-address relationships and Salesforce records that support activities.

Best use case: Organizations that primarily want Salesforce functionality available inside Gmail or Outlook.

Verdict: Excellent inbox integration. Not necessarily a complete activity-capture strategy.

3. Einstein Activity Capture: Salesforce's Native Email Sync

Einstein Activity Capture connects Microsoft or Google accounts to Salesforce and automatically captures email and event activity, associating it with relevant Salesforce records.

This is where Salesforce email sync becomes significantly more powerful.

Instead of asking a rep to remember if they logged an email, the system captures activity automatically.

What is Einstein Activity Capture?

Einstein Activity Capture, commonly called EAC, is Salesforce’s activity-capture technology for automatically bringing email and calendar activity into Salesforce.

It can capture emails, calendar events, participants and other related activity, and associate the information with Salesforce records.

Salesforce describes the current architecture as capturing email messages and storing them as EmailMessage and Task records when Sync Email as Salesforce Activity is enabled.

This is an important change from the older EAC architecture.

The Biggest EAC Change: Salesforce Made Email Data More Native

Historically, one of the major criticisms of EAC was that captured email data did not behave like normal Salesforce records. That changed.

Starting with Summer ’25, Salesforce introduced Sync Email as Salesforce Activity.

With this architecture, captured emails can be stored as standard Salesforce activity data and become accessible to reports, workflows, flows, triggers, APIs, other Salesforce platform capabilities and AI-powered features.

Salesforce is also migrating existing EAC implementations to the newer architecture during 2026. The migration date is org-specific, with notifications rolling out from June 2026.

How EAC Email Sync Works

The basic architecture is:

Gmail / Microsoft 365

↓

Einstein Activity Capture

↓

Email matching

↓

Salesforce Activity / EmailMessage records

↓

Accounts, Contacts, Leads, Opportunities and other supported records

↓

Reports, automation, APIs and AI

Salesforce also allows admins to control whether entire emails or only email headers are captured. Header-only capture includes sender, recipients and timestamp but excludes the subject and body.

That can be useful for organizations with stricter privacy requirements.

What EAC Does Well

1. Automatic capture

The biggest benefit is obvious: Reps don’t have to remember to log every email. That dramatically reduces the manual data-entry burden.

2. Native Salesforce data

With Sync Email as Salesforce Activity, captured emails become Salesforce activity records rather than living only in an external activity layer.

3. Reporting and automation

Because the activity becomes Salesforce data, teams can use it in reporting, workflows, triggers and APIs.

4. AI context

Email activity can also feed Salesforce’s broader intelligence and AI capabilities.

Salesforce explicitly describes EAC as providing context for AI agents and features.

5. Custom matching

Salesforce has introduced Flow actions for matching email activity to records, allowing admins to customize how emails are associated with CRM data.

This is a significant improvement over the older, more rigid EAC model.

EAC Limitations Admins Should Understand

This is where a proper Salesforce email integration evaluation becomes important.

EAC is considerably more capable in 2026 than it was a few years ago.

But automatic capture does not automatically mean complete, clean or useful CRM data.

1. Email aliases aren't supported

Salesforce explicitly states that EAC requires the connected email account to be the user’s primary account and that email aliases aren’t supported.

That matters in organizations where people use multiple domains, brand aliases, acquired-company addresses, regional addresses or secondary sending identities.

An enterprise environment is rarely as simple as: One Salesforce user = one email address.

2. Matching is still a critical problem

Getting an email into Salesforce is only half the problem. The more important question is where does it go?

Salesforce uses email addresses and CRM relationships to match activity. The newer architecture allows admins to customize matching with Flow, which is powerful.

But complex organizations can have:

Multiple contacts with similar information
Multiple opportunities at one account
Parent and child accounts
Multiple business units
Partner-led opportunities
Acquired domains
Shared mailboxes
Multiple buying groups
The same stakeholder involved in several deals

The more complex the data model, the more important matching becomes.

A system that captures 100% of emails but attaches 20% to the wrong opportunity is not a successful email sync.

3. Email aliases and shared mailbox scenarios require attention

EAC’s user-to-mailbox architecture is designed around a connected primary account.

If your organization relies heavily on:

sales@
support@
partnerships@
Regional mailboxes
Shared addresses
Multiple identities

you should test the exact workflow before deployment.

Salesforce’s Outlook documentation also identifies limitations around true shared mailboxes in Microsoft add-ins and distinguishes them from certain supported shared-folder/delegated configurations.

4. Storage becomes part of the equation

This is one of the biggest changes admins need to understand in 2026.

The newer Sync Email as Salesforce Activity model makes email data more usable because it becomes Salesforce data. But that also means storage matters.

Salesforce explicitly notes that synced emails and tasks are subject to Salesforce data-storage limits and recommends managing and archiving email data.

This creates a trade-off:

More native data → more Salesforce utility

but potentially:

More native data → more Salesforce storage consumption

For a large enterprise with millions of emails, that is not a trivial consideration.

5. Duplicate activity is possible

Salesforce warns that when Sync Email as Salesforce Activity is enabled, users can still manually log emails.

If the same message is automatically synced and manually logged through the Outlook/Gmail integration, you can create duplicate activity records.

This means admins need to think about the interaction between: automatic email sync + manual logging.

6. Matching can take time

Salesforce documents scenarios where emails captured before or shortly after a Salesforce record is created may not immediately appear on the relevant Activity Timeline.

In some cases, propagation can take up to 24 hours.

For teams expecting real-time activity visibility, this is worth understanding.

7. There are email-address limits

Salesforce can associate up to 50 unique email addresses from the From, To and CC fields with contact records. Additional addresses are ignored.

That’s unlikely to matter for a normal one-to-one email.

It can matter for large group emails, events and complex stakeholder communications.

How Much Does Einstein Activity Capture Cost?

Einstein Activity Capture availability depends on the Salesforce edition and associated licenses.

Salesforce currently lists EAC Standard across several Sales Cloud editions, while enhanced capabilities can be associated with products such as Sales Engagement, Einstein for Sales and Revenue Intelligence.

For example, Salesforce currently lists: Sales Engagement at $50/user/month, billed annually, and EAC is included as part of Sales Engagement.

Salesforce’s broader pricing also varies substantially by Sales Cloud edition and add-on configuration. A good question to ask when calculating the cost of EAC is: Which Salesforce license do we already have, what EAC capability does it include, and what additional Salesforce products or storage will we need?

4. Sales Engagement Platforms

The next category is sales engagement platforms. These tools are designed primarily to help sellers and SDRs prospect and engage buyers through email, cadences, tasks, calls, sequences, engagement tracking and follow-ups.

Examples include platforms such as Salesforce Sales Engagement and other sales engagement technologies.

Salesforce’s own Sales Engagement product includes cadences, work queues, lead scoring, email productivity functionality and Einstein Activity Capture. It currently starts at $50/user/month when purchased separately.

Where sales engagement platforms are strong

They’re excellent when the problem is how to help SDRs and sellers execute outreach at scale.

They can provide automated sequences, email engagement tracking, task management, cadences, and prospecting workflows.

But sales engagement isn't the same as complete activity capture

This distinction matters.

A sales engagement platform knows a lot about the emails its users send through its engagement workflows. That does not necessarily mean it has a complete picture of every customer interaction.

Consider:

An AE sends an email manually
A customer replies
A VP joins the conversation
Someone schedules a meeting
Another stakeholder sends an email
A deal moves forward
The rep changes email clients

A sales engagement platform may be excellent at managing the outbound sequence while being less suited to becoming the system of record for every customer relationship touchpoint.

Best use case: SDR/BDR teams and organizations focused on structured outbound and seller engagement.

Verdict: Great for orchestrating engagement. Don’t automatically assume it is a complete CRM activity-capture layer.

5. Dedicated Salesforce Email and Activity Capture Platforms

The final category is dedicated activity-capture software. These platforms exist primarily to capture what revenue teams are actually doing and turn it into useful CRM data.

This is where products such as Nektar fit. The architectural difference is important.

The goal isn’t simply to move emails into Salesforce. It’s to capture the broader customer activity happening across email and meetings, turn that activity into structured, actionable revenue data, and then bring it into Salesforce in a way that can be used across the organization.

That distinction is becoming increasingly important as companies build AI, automation, reporting, and intelligence on top of their CRM, because the value of the system depends not just on how much data it contains, but on how complete, connected, and usable that data is.

Salesforce Email Integration Checklist

A serious evaluation should go beyond asking “Does it sync email?” Use this checklist to assess whether a solution can actually capture and structure the activity your revenue team generates.

Email coverage

Incoming emails
Outgoing emails
Replies and email threads
Emails with multiple participants
Historical email activity
Multiple domains
Email aliases
Shared mailboxes

Meeting coverage

Calendar events
Invited participants
Actual meeting participants
Meeting activity
Historical meetings

CRM association

Contacts
Leads
Accounts
Opportunities
Opportunity Contact Roles
Custom objects
Multiple opportunities under the same account
Complex account structures

Data enrichment & intelligence

Automatically identify new contacts
Identify relevant stakeholders
Determine buying roles
Track engagement frequency
Measure relationship strength
Identify multi-threaded opportunities
Show buying-group coverage

The key distinction: If a solution checks only the first few boxes, you’re primarily looking at activity capture.

If it can also connect that activity to people, accounts, opportunities, buying roles, relationships, and buying groups, you’re moving toward revenue intelligence.

That’s the difference to keep in mind when evaluating Salesforce email integration: capturing activity tells you what happened; structuring that activity tells you what it means.

Nektar vs Salesforce Email Sync

Nektar approaches the problem from the other direction. The objective isn’t simply to get more emails into Salesforce. It’s to make the activity already happening across email and meetings useful CRM data.

Nektar captures email and meeting activity and can write the resulting data into Salesforce standard and custom objects and fields.

That includes capabilities such as:

Automatically identifying contacts
Associating activity with opportunities
Populating Opportunity Contact Roles
Measuring engagement
Identifying stakeholders
Tracking multi-threading
Working with custom Salesforce fields and objects

Nektar’s configurable OCR functionality, for example, can create Opportunity Contact Roles based on configurable engagement conditions and assign buying roles using information such as job titles and engagement behavior.

That’s a fundamentally different outcome from simply logging an email.

Salesforce EAC vs Nektar: What's the Difference?

The simplest way to think about the difference is EAC captures activity in Salesforce and Nektar captures activity and turns it into structured relationship and buying-group intelligence.

Here’s how that difference plays out.

Capability	Salesforce EAC	Nektar
Email capture	Yes	Yes
Calendar capture	Yes	Yes
Automatic capture	Yes	Yes
Salesforce activity records	Yes	Yes
Standard Salesforce objects	Yes	Yes
Custom Salesforce data	Configurable matching / platform-dependent	Yes
Email alias support	Limited; aliases aren't supported as connected accounts	Designed for broader activity coverage
Contact creation	Not the core EAC function	Yes
Opportunity Contact Roles	Not automatically created from every interaction	Automated/configurable
Buying-group intelligence	Limited	Core capability
Multi-threading intelligence	Not the primary function	Core capability
Engagement scoring	Limited	Yes
Historical context	Salesforce-defined limits/migration paths	Historical activity capabilities
Cost	Included up to 100 users, paid tier above that	Paid, usage-based
Rep behavior change	Low	Low
Primary purpose	Salesforce activity capture	Revenue relationship intelligence

The important caveat is that EAC has evolved significantly. Salesforce’s current architecture is substantially more capable than older versions of EAC, particularly because captured email can now become standard activity data and can be accessed through reports, workflows, APIs and other platform capabilities.

Salesforce Email Integration Comparison: Which Option Should You Choose?

Here’s the practical decision framework.

If your requirement is...	Start with...
Log a handful of emails	Manual logging
Work with Salesforce from Gmail/Outlook	Salesforce Outlook/Gmail integration
Automatically capture email	Einstein Activity Capture
Run outbound cadences	Sales engagement platform
Capture all revenue activity and turn it into structured CRM intelligence	Dedicated activity capture
Automatically identify stakeholders	Dedicated activity capture
Build buying-group visibility	Dedicated activity capture
Populate Opportunity Contact Roles automatically	Dedicated activity capture
Support complex CRM objects and workflows	Dedicated activity capture
Minimize rep data-entry	EAC or dedicated capture
Need complete historical relationship context	Dedicated capture / carefully evaluated migration

What Should Salesforce Email Integration Actually Achieve?

Email sync isn’t the end goal. It’s the means to a larger business outcome, and that outcome looks different for every team using Salesforce.

For Sales, the goal is to give managers a complete view of deal engagement: who is involved, how actively they’re engaging, and whether an opportunity is actually progressing.

For RevOps, it’s about reducing the reliance on reps to manually maintain CRM activity and making sure important customer interactions are captured consistently without adding more administrative work.

For Marketing, the goal is to understand which stakeholders are actually engaged with an account, rather than relying only on the contacts stored in Salesforce or assuming that every contact associated with an account is actively involved.

For Customer Success, having the full relationship history matters. When an account changes hands, the new owner should be able to understand the conversations, stakeholders, and engagement that came before them instead of starting with a blank slate.

For Leadership, the objective may be to understand the strength of strategic account relationships. Are multiple stakeholders engaged, or is the company relying on a single contact? Is the team genuinely multi-threaded, or does the CRM simply make it look that way?

And for AI, the requirement is even broader. AI agents need clean, connected, contextual customer data to reason effectively about accounts and opportunities. If important relationship activity exists only in individual inboxes, the AI has no way to see or understand it.

These are much bigger requirements than simply “log my emails in Salesforce.” Email capture is only the starting point. The real value comes from turning that activity into information the entire revenue organization, and increasingly, the AI systems supporting it can actually use.

The AI question: Why Email Sync Matters More Now

A CRM is increasingly not just a database for humans. It’s becoming an input layer for AI. Salesforce itself is positioning EAC activity as context for AI-powered features and agents.

But AI can only reason over the information it can access.

Imagine Salesforce shows a $500K opportunity with John Smith listed as the primary contact. Technically, the CRM is populated, but it doesn’t tell you much about how the deal is actually progressing.

Behind that opportunity, there may be an entire network of stakeholders: John as the VP, Sarah as the economic buyer, Mike as the technical evaluator, Priya from procurement, David from security, and two active champions helping move the deal forward.

If those relationships exist only across email threads and meetings, Salesforce has the opportunity and the contact, but not the full picture.

That’s the difference between having data in your CRM and having context in your CRM.

And that’s why the next generation of Salesforce email integration isn’t simply about capturing more messages. It’s about turning those interactions into an understanding of the relationships, stakeholders, and engagement patterns behind them.

The Salesforce Email Sync Checklist: What to Test Before You Choose a Solution

Before rolling out any Salesforce email integration, don’t stop at “Does it sync email?” Test it against the situations your revenue team actually encounters. A solution that works perfectly for a simple one-to-one email can behave very differently when you introduce aliases, shared mailboxes, multiple opportunities, long threads, or complex Salesforce data.

1. Email coverage

Start with the basics. Does the solution capture both incoming and outgoing emails, including replies and long email threads? Then test less straightforward scenarios such as large group emails, email aliases, multiple domains, and shared mailboxes. These are often where gaps in coverage become apparent.

2. CRM matching

Getting an email into Salesforce is only useful if it ends up on the right record. Test how the solution matches activity to contacts, leads, accounts, and opportunities. If an account has multiple active opportunities, can the system distinguish between them? Also test parent and child accounts, custom objects, and Opportunity Contact Roles. The more complex your Salesforce data model, the more important accurate matching becomes.

3. Historical data

Don’t evaluate only what happens from the day you switch the integration on. Find out how much historical activity can be captured and whether older emails can be backfilled. Test what happens when an account or opportunity is created after an email was sent. Can that historical activity subsequently be associated with the new record? If you’re replacing an existing solution, can your historical activity be migrated or re-associated?

4. Data quality

Automatic capture is only valuable when the resulting data is accurate. Look at how the solution handles duplicate emails, prevents activity from being attached to the wrong record, and identifies or creates contacts. Then go beyond basic activity logging: can it identify stakeholders, understand multi-threaded engagement, and give you visibility into the broader buying group?

5. Administration and governance

Email capture touches sensitive customer and employee data, so the administrative side matters just as much as the feature list. Evaluate the setup and authentication process, Microsoft Graph requirements where applicable, privacy controls, data retention, Salesforce storage impact, reporting capabilities, API access, and your options for backing up or exporting the captured data.

6. Rep adoption

Finally, ask the question that often determines whether an email integration succeeds: How much does the salesperson actually have to do?

If the answer is “They have to remember to log it,” you’re still relying on manual CRM hygiene.

The closer you can get to capturing activity automatically, accurately associating it with the right Salesforce records, and turning that activity into useful CRM context, the more value you’ll get from your email integration.

So, Which Salesforce Email Integration Is Right for You?

The right Salesforce email integration depends on what you’re actually trying to solve.

If your team only needs to record the occasional customer conversation, manual email logging may be all you need. If the priority is giving reps access to Salesforce while they work in Gmail or Outlook, Salesforce’s native integrations are a natural fit. If you want email and calendar activity to be captured automatically within Salesforce, Einstein Activity Capture is the place to start. And if your primary focus is running outbound sequences and managing prospect engagement, a sales engagement platform may make more sense.

But there’s another requirement that is becoming increasingly common among enterprise revenue teams:

“We want Salesforce to understand the customer relationships happening across our organization without asking reps to document everything themselves.”

That’s a bigger problem than email logging.

It requires capturing activity across conversations, connecting it to the right accounts and opportunities, identifying the people involved, and turning those interactions into structured relationship and revenue intelligence.

That’s where dedicated activity-capture platforms come in.

Nektar: From Email Capture to Revenue Intelligence

Nektar takes Salesforce email integration a step further. It captures email and meeting activity in the background and turns those interactions into structured, actionable Salesforce data.

Instead of relying on reps to keep the CRM updated, Nektar can automate the work that typically gets missed between conversations. That can include creating contacts, adding Opportunity Contact Roles, updating stakeholder information, recording meetings, tracking engagement, and maintaining buying-group data.

Because this information is derived from the activity already happening across email and meetings, your CRM can reflect the relationships forming around an account—not just the contacts someone remembered to enter.

Nektar can populate Salesforce standard and custom objects and fields, identify stakeholders, and automate or configure contact and opportunity-role creation based on engagement and relationship data.

And that’s an important distinction.

Getting email into Salesforce is only the beginning. The more valuable question is:

Can Salesforce understand what those conversations mean for the account, the opportunity, and the buying group?

That’s the gap Nektar is designed to close: moving from activity capture to relationship intelligence, so Salesforce becomes a more complete and useful representation of what’s actually happening across your revenue organization.

Frequently Asked Questions

Q. What is Salesforce email integration?

Salesforce email integration connects an email platform such as Gmail or Microsoft Outlook with Salesforce so users can access Salesforce records from their inbox and associate email activity with CRM records. Automatic email capture can be added through Einstein Activity Capture or a dedicated activity-capture platform.

Q: How do I sync email to Salesforce?

There are several options. You can manually log emails, use Salesforce's Gmail or Outlook integration, enable Einstein Activity Capture for automatic capture, or use a dedicated third-party activity-capture platform. The right option depends on whether you need manual logging, automatic capture, historical data, complex matching or broader revenue intelligence.

Q: What is Salesforce email sync?

Salesforce email sync generally refers to automatically bringing email activity from Gmail or Microsoft Outlook into Salesforce. Salesforce's Einstein Activity Capture supports automatic email synchronization, and with Sync Email as Salesforce Activity enabled, captured emails can be stored as Salesforce EmailMessage and Task records.

Q: Does Salesforce automatically log emails?

Not simply because the Outlook or Gmail integration is installed. The native Outlook/Gmail integration lets users relate and log emails, while Einstein Activity Capture is designed for automatic activity capture.

Q: Is Einstein Activity Capture still relevant in 2026?

Yes. EAC has changed significantly. Salesforce introduced Sync Email as Salesforce Activity, which stores captured email as Salesforce activity data and makes it available to reports, workflows, APIs and other platform capabilities. Salesforce is also migrating older EAC implementations to the newer architecture during 2026.

Q: Does Einstein Activity Capture store emails in Salesforce?

With Sync Email as Salesforce Activity enabled, matched captured emails are stored as Salesforce EmailMessage and Task records. Older EAC configurations can behave differently, so admins should check which architecture their org uses.

Q: How do I log email in Salesforce?

You can log an email in Salesforce manually through the Salesforce integration for Gmail or Outlook. From your inbox, you can relate an email to the relevant Salesforce record, such as a contact, lead, account, or opportunity. Salesforce also supports Enhanced Email, which stores logged emails as EmailMessage records in Salesforce.

If you want emails to be logged automatically rather than relying on reps to manually record each interaction, you can use Einstein Activity Capture or a dedicated email and activity-capture solution. The key difference is that manual email logging depends on reps consistently taking action, while automatic capture happens in the background.

For organizations handling a high volume of customer conversations, the bigger consideration is not simply whether you can log an email in Salesforce, but whether those emails are automatically captured, correctly associated with the right CRM records, and turned into useful relationship and opportunity data.

Q: Does Salesforce email integration support Gmail?

Yes. Salesforce provides a native Gmail integration that lets users work with Salesforce records from Gmail and relate email activity to Salesforce. Einstein Activity Capture can additionally capture activity from connected Google accounts.

Q: Does Salesforce email integration support Outlook?

Yes. Salesforce provides a native Outlook add-in, while Einstein Activity Capture can automatically capture activity from connected Microsoft accounts. Salesforce has also been migrating Microsoft 365 EAC authentication to Microsoft Graph ahead of Microsoft's October 2026 EWS retirement.

Q: Does Einstein Activity Capture support email aliases?

No. Salesforce states that EAC requires the user's primary connected email account and doesn't support email aliases as connected accounts.

Q: Can Salesforce email sync create duplicate activities?

It can if automatic EAC capture is combined with manual email logging. Salesforce explicitly warns that the same email can be logged twice when automatic sync and manual logging are both used.

Q: Does Salesforce email sync count toward storage?

With Sync Email as Salesforce Activity, synced email and task records are subject to Salesforce data-storage limits. Salesforce recommends archiving email data to manage storage.

Q: How many email recipients can Salesforce match?

For Sync Email as Salesforce Activity, Salesforce can associate up to 50 unique email addresses from the From, To and CC fields with contact records. Additional addresses are ignored.

Q: Can Salesforce email integration work with custom objects?

The answer depends on which Salesforce email capability you're using and how the custom object is configured. Salesforce's Outlook/Gmail integrations can work with records created from custom objects when they support activities, while the newer EAC architecture provides Flow-based matching capabilities. Test your exact custom-object workflow before deployment.

Q: What is the best Salesforce email integration for enterprise teams??

It depends on the requirement. Native Salesforce integrations are a good fit for basic inbox productivity. EAC is a strong choice for Salesforce-native automatic activity capture. Sales engagement platforms are suited to outbound execution. Dedicated activity-capture platforms such as Nektar become more relevant when the goal is complete activity coverage, complex CRM matching, stakeholder intelligence and buying-group visibility.
