Why teams connect Lemlist and Salesloft

Sync what happens in Lemlist with the customer records in Salesloft, in real time and in both directions.

The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Lemlist holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.

Stacksync connects Unsubscribes, Webhooks, Team Members, Campaigns in Lemlist to Calls, Tasks, Meetings, Users in Salesloft with bi-directional, real-time sync. Activity and record changes in Lemlist update the matching contact or account in Salesloft, and CRM data flows the other way wherever Lemlist can store and use it.

Common use cases

  • Sync replies, opens, and bounces from Lemlist into the CRM so outbound activity shows on lead and contact records
  • Push enriched leads from a warehouse or list-building workflow into Lemlist campaigns automatically
  • Sync people, cadence memberships, and outcomes into a warehouse so RevOps can report on sequence performance next to pipeline data.
  • Auto-enroll leads into cadences when a row in an enrichment database meets a scoring condition.
