Lemlist + Salesforce integration
Bring every Lemlist touch into Salesforce. OutboundSync logs email and social steps on the Lead or Contact, and keeps Lemlist Unsubscribe in step with your Salesforce reports.

Lemlist + Salesforce at a glance
Lemlist connects to Salesforce through OutboundSync. Email sends, opens, clicks, replies, bounces, and unsubscribes, plus connection requests, social messages, and social replies, are logged on the matching Lead or Contact as Tasks, or as EmailMessage records for email. Salesforce reports can also feed Lemlist's Unsubscribe list, so suppression follows your CRM.
| Status | Live |
|---|---|
| Channels | Email and social |
| Direction | Activity Lemlist → Salesforce; block lists Salesforce → Lemlist |
| Salesforce records | Leads, or Contacts and Accounts |
| Block lists | Yes, from Salesforce reports |
| Lemlist plan | Needs webhook access |
| Setup | Self-serve: create an External Client App, then connect it in OutboundSync |
Salesforce reports can only credit the activity they can see, and email-only logging misses every social step. OutboundSync writes each Lemlist step as a Task on the Lead or Contact, with optional OutboundSync fields for the latest activity. Subject templates carry the event and campaign, so a report can split email from social without manual tagging.
Suppression works from the same source. Point OutboundSync at a Salesforce report, for example Contacts on open opportunities or accounts another team owns, and the people in it are pushed to Lemlist as Unsubscribe entries. Each list picks Email for addresses and domains, or Social for profile URLs.

Ways to connect Lemlist and Salesforce
The options teams weigh before they commit a production sync.
| Option | What it does | Trade-off |
|---|---|---|
| Zapier, Make, or n8nCompare integration platforms | Catch Lemlist webhooks and write each event to Salesforce with a workflow you build. | Every event type, retry, and field change is a workflow you maintain, billed per task or step. |
| Custom buildBuild vs buy | Write your own service against the Lemlist and Salesforce APIs. | You own matching, deduplication, API limits, and every upstream schema change. |
| OutboundSync | Pre-built email and social activity sync into Salesforce Leads and Contacts, with Salesforce reports pushed back as block lists. | Self-serve setup, searchable event logs, and support from the team that maintains the connector. |
How to set up Lemlist + Salesforce
Step 1: Connect Salesforce

Step 2: Connect Lemlist
Add your Lemlist API key in OutboundSync, then paste the source's webhook URL into Lemlist.
Step 3: Choose events and fields
Pick which Lemlist events to log, whether they write Tasks or EmailMessage records, and which OutboundSync fields to fill.
Step 4: Add a block list
Point a Salesforce report of customers, open deals, or do-not-contact records at Lemlist so they never get cold outreach.
Step 5: Send a test event
Trigger one Lemlist event and confirm it on a real Lead or Contact.
Step 6: Go live
Turn on the source and start building Salesforce reports, dashboards, and Flows on real Lemlist data.

|
| EnterpriseMost common | Recommended - Best balance of capability, API capacity, and cost. |
