Why teams connect Lemlist and Twilio

Stop re-entering the same information in Lemlist and Twilio: Stacksync keeps the records they share consistent in real time, in both directions.

Two tools in the daily stack often hold overlapping information: the same people, the same companies, or the same pieces of work, described twice. The tools do different jobs, so consolidating is not the answer; the overlap just needs to stop drifting.

Stacksync syncs Activities, Unsubscribes, Webhooks, Team Members in Lemlist with Calls, Incoming Phone Numbers, Outgoing Caller IDs, Accounts in Twilio in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.

Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.

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 delivery and error statuses back into the system that initiated the send, so failed messages surface where the campaign lives.
  • Mirror Verify outcomes into a user database to gate onboarding steps on completed phone verification.

Where both tools track people or companies: one consistent record

Contact and company details corrected in either tool update the other, so nobody works from the old version.

Where one tool produces events: mirror them in the other

Payments, replies, messages, or tickets created in one tool can create or update matching records in the other, keeping context in one place.

Where Twilio is where the team documents or plans: keep its data fed

Information that originates in Lemlist stays current in Twilio instead of going stale after a one-time paste.
