Salesloft and Salesforce are designed to work together. Salesloft’s CRM Sync connects sales engagement activity with Salesforce, allowing teams to synchronize records, log activities, map fields, and automate data movement between the two systems.
But there is an important distinction between integrating a sales engagement platform with Salesforce and building a complete record of customer activity and relationships inside Salesforce.
Salesloft’s documentation focuses primarily on what the integration can synchronize. For revenue teams evaluating Salesforce data quality, the more useful question is what happens at the edges of that integration.
What gets captured? What gets written to Salesforce? What object does it become? And what information can still remain outside the CRM?

What Does Salesloft Capture?
Salesloft captures engagement activity generated through its sales engagement platform, including emails, calls, cadence activity and other seller interactions.
Its Salesforce integration is designed to synchronize both CRM records and activity data. Salesloft says its CRM Sync can automatically record calls and emails as activities in Salesforce, while pushing more than 30 activity properties, including call duration, call disposition, sentiment, email activity counts and cadence identifiers.
The integration also works with Salesforce Leads, Contacts, Accounts and Opportunities.
Salesloft describes the connection as bidirectional, allowing records and field updates to move between Salesforce and Salesloft. Administrators can configure field mappings, determine which system has priority for particular fields, and define synchronization rules.
Salesloft also provides a sync log showing transferred records, fields, timing, direction and outcomes, allowing administrators to troubleshoot failed syncs and mapping errors.
That makes Salesloft more than a simple activity logger. It is designed to keep the sales engagement system and Salesforce synchronized.
But synchronization is not the same thing as comprehensive relationship intelligence.
What Does Salesloft Write to Salesforce?
Salesloft primarily writes two categories of information back into Salesforce.
1. CRM records and field updates
Salesloft can synchronize Salesforce Leads, Contacts, Accounts and Opportunities.
Administrators can configure field mappings and determine the direction and priority of individual fields. Salesloft’s CRM Sync also supports automation rules that can execute actions based on defined criteria.
This means Salesforce can remain the source of important CRM information while Salesloft uses that information to drive sales engagement workflows.
2. Sales activities
Salesloft can write calls and emails into Salesforce as activities.
Those activities can carry additional information such as:
- Call duration
- Call disposition
- Sentiment
- Email activity counts
- Cadence identifiers
- Other activity properties
Salesloft has also expanded its activity logging to account for multiple people involved in an email or meeting. The company says that when multiple people are copied on an email or included in a meeting, the activity can be logged to each person’s Salesforce Contact record. It also says that if someone without a CRM record is copied on an email or meeting, Salesloft can automatically create the Contact record.
That is significant for organizations trying to capture more than one stakeholder in a deal.
What about Clari Capture and Salesforce?
The Salesforce integration story becomes more interesting following the Clari-Salesloft merger.
Clari and Salesloft completed their merger on December 3, 2025. The combined company now operates as Salesloft, with Clari Forecast retaining the Clari name while Clari’s broader revenue intelligence, deal management and conversation intelligence capabilities continue under the Salesloft brand.
For existing Clari customers, that creates a practical Salesforce question: What happens to Clari Capture, and how does it fit into the Salesforce activity-capture architecture going forward?
The distinction matters because Clari and Salesloft have historically addressed different parts of the revenue workflow.
Salesloft’s CRM Sync is designed to move sales engagement activity between Salesloft and Salesforce. Clari’s platform has historically used activity and revenue signals to support forecasting, deal inspection and revenue intelligence.
Salesloft’s current platform brings these capabilities together under one company and one broader Predictive Revenue System.
For an existing Clari customer, however, the immediate concern is not the corporate structure. It is the data flow into Salesforce.
The Clari Capture Question
Clari’s broader platform has historically relied on activity and engagement data as an input to revenue intelligence.
Salesloft’s current Salesforce offering, meanwhile, prominently documents CRM Sync as the mechanism for synchronizing Leads, Contacts, Accounts and Opportunities and automatically recording Salesloft activities in Salesforce.
That leaves an important implementation question for organizations that previously used Clari’s capture capabilities:
Which system is now responsible for capturing activity, and how does that activity reach Salesforce?
This is particularly important for customers approaching a renewal, changing their Salesloft/Clari configuration, or reviewing their Salesforce activity architecture after the merger.
What Should Clari Customers Clarify?
Before changing an existing Salesforce configuration, teams should establish:
- Is the organization using Clari Capture, Salesloft CRM Sync, or another activity-capture mechanism?
- Which system is responsible for capturing email and calendar activity?
- Where is captured activity stored?
- Which Salesforce objects receive that activity?
- What happens to historical activity if the capture configuration changes?
- Is Einstein Activity Capture enabled or disabled?
- Are other Salesforce synchronization tools operating for the same users?
- Which product now owns the relevant activity-capture workflow?
- How are contacts and activities handled when a person is not already represented in Salesforce?
These questions matter because changing the capture layer can change what appears in Salesforce reporting, what data is available to downstream systems, and how historical activity is preserved.
The Salesforce Activity-capture Configuration Matters
A December 19, 2025 recommendation in the Clari/Salesloft community stated: “Salesforce Lightning Sync and Einstein Activity Capture should remain disabled.”
That guidance is particularly relevant when multiple systems could otherwise attempt to synchronize the same Salesforce activity.
Salesforce itself also documents that Einstein Activity Capture and Lightning Sync cannot be enabled simultaneously in the same Salesforce org.
For existing Clari customers, the takeaway is not simply to turn a particular Salesforce feature on or off. It is to understand which system owns activity capture and which system writes the resulting data into Salesforce before changing the configuration.
Where Salesloft Stops
Salesloft can synchronize a substantial amount of engagement and CRM data. But the integration remains centered on Salesloft activity and the CRM records connected to that activity.
That distinction matters.
A Salesforce record can tell you that an email happened, a call happened, who was involved and which cadence generated the activity. It does not necessarily mean Salesforce now contains the complete history of every customer interaction across the revenue organization.
Activities that happen outside Salesloft remain outside the Salesloft-to-Salesforce activity stream.
For example, a buyer interaction can happen through:
- A rep’s normal email workflow
- A meeting that wasn’t captured through the engagement platform
- Conversations involving customer success
- Executive-to-executive communication
- Partner interactions
- Other channels outside the Salesloft workflow
The Salesforce integration does not turn every external customer interaction into a Salesloft activity simply because Salesforce is connected.
That is the boundary worth understanding.
What Happens When the Salesforce Connection is Unavailable?
There is another useful way to understand the boundary: what happens when the CRM connection itself is interrupted.
Salesloft’s Trust Center documentation states that when the Salesforce integration is disabled, activities do not log from Salesloft to Salesforce, records cannot be imported from Salesforce, and field updates between Salesforce and Salesloft stop syncing. It also states that records in Salesloft cannot be created in Salesforce and new or unlinked records cannot be linked to a CRM record during the interruption.
This illustrates an important architectural dependency.
Salesloft can continue operating for core sales-engagement activities, but Salesforce synchronization is dependent on the CRM connection being available.
For teams relying on Salesforce as the system of record, that distinction matters when designing reporting, data governance and downstream AI workflows.
What Does This Mean for Salesforce Reporting?
For sales engagement reporting, Salesloft’s Salesforce integration can provide useful structured activity data.
Salesloft highlights the ability to combine Salesloft and Salesforce data for analytics and attribution. Its Salesforce integration supports automation rules and detailed activity properties, while the platform provides a sync log to monitor data moving between the systems.
But Salesforce reporting is only as complete as the data that reaches Salesforce.
If Salesforce contains Salesloft activity but not the activity happening outside Salesloft, reports can still provide an incomplete picture of account engagement.
That can affect questions such as:
- How many stakeholders are actually engaged?
- Which people have interacted with the account?
- How many conversations happened across the entire account?
- Which relationships are strongest?
- What activity happened outside the sales engagement workflow?
- How much customer context exists before an opportunity moves stage?
The integration improves the activity record.
It does not automatically make Salesforce the complete system of relationship context.
What Does This Mean for AI in Salesforce?
AI systems need more than activity volume. They need connected, contextual data.
An AI system working from Salesforce can reason over the information that actually exists in the CRM. If the CRM contains a detailed record of Salesloft activity but customer interactions are distributed across other channels, the model is working from a partial context window.
That can affect AI-generated:
- Opportunity summaries
- Account research
- Buying-group identification
- Next-step recommendations
- Relationship analysis
- Forecasting signals
The issue isn’t whether Salesloft captures data well. It is what happens to the customer context that never passes through Salesloft.
Salesloft can make Salesforce more complete for Salesloft-generated activity. It does not, by itself, make Salesforce a complete record of every customer relationship.
Salesloft + Salesforce: The Practical Takeaway
Salesloft’s Salesforce integration is built to synchronize CRM records and sales engagement activity between two systems.
The important distinction for RevOps teams is between Sales engagement synchronization and complete customer context in Salesforce.
Salesloft’s current CRM Sync provides bidirectional synchronization for Leads, Contacts, Accounts and Opportunities, automatic activity logging, field mapping, automation rules and visibility into synchronization activity.
Following the Clari-Salesloft merger, existing Clari customers also need to understand how their current activity-capture architecture fits into the combined platform and which system is responsible for getting activity into Salesforce. The combined company says the capabilities Clari customers rely on continue under the Salesloft brand, with Clari Forecast retaining its name.
If the objective is to understand what Salesloft captures and writes to Salesforce, the vendor’s CRM Sync provides extensive capabilities.
If the objective is to understand every person, relationship and interaction surrounding an account, the integration’s boundaries become equally important.
