What this integration does

The Lemlist integration lets you push enriched contacts into Lemlist campaigns. Contacts can be pushed:

  • Automatically — via a Signal's configure step, as contacts are enriched on each run

  • In bulk — from the Contacts manager, on demand

  • Conditionally — via an AI Agent action, only when the agent's output matches your rule

Connecting Lemlist

  1. Go to Integrations in the left sidebar.

  2. Find Lemlist and click Configure.

  3. Enter your Lemlist API key.

  4. Click Save to connect.

To find your API key, log in to your Lemlist account and go to your account or API settings.

Pushing contacts from a Signal (automatic)

In the Signal Configure step, once contact enrichment is enabled, Lemlist becomes available as a push destination on the Integrations step of the Signal wizard.

  1. In the Signal wizard, go to the Integrations step.

  2. Find Lemlist and enable it.

  3. Select the campaign to enroll contacts into.

  4. Save the Signal.

Every contact enriched by this Signal is automatically pushed to your selected Lemlist campaign on each run.

Pushing contacts from the Contacts manager (manual)

  1. Go to Contacts in the left sidebar.

  2. Select the contacts you want to push.

  3. Click Export → Lemlist.

  4. Select the campaign.

  5. Confirm the push.

Batch limit: 150 contacts per push. If you've selected more, only the first contacts in your selection are sent. Use filters to push in segments if needed.

Pushing contacts via AI Agent (conditional)

In the AI Agent Actions step, add a conditional action and choose Add to Lemlist Campaign. Select the campaign. The push fires only when the agent's output matches your condition — ensuring only AI-qualified contacts reach your Lemlist campaigns.

Example:

  • ICP Verifier agent → output equals TRUE → push to Lemlist campaign

  • Output equals FALSE → skip

This protects your campaign deliverability by ensuring only relevant contacts are enrolled.

Requirements

Contacts must have been saved as enriched contacts before they can be pushed to Lemlist. Raw reactions, comments, or post data cannot be pushed directly — enrichment (2 credits) must have completed first.

For best results, enable the email finder on your Signal or run it from the Contacts manager before pushing to Lemlist — most email sequencing tools require a verified email address to enroll a contact.
