Lemlist trigger

Overview

Receives webhook notifications from Lemlist when email outreach and sales engagement events occur. Supports over 40 event types including email sends, opens, clicks, replies, bounces, unsubscribes, LinkedIn interactions (visits, invites, replies, voice notes), Aircall events, API actions, and campaign lifecycle events (paused, resumed, connection issues). Can filter by specific campaign and first-occurrence only. Useful for automating follow-ups based on prospect engagement, syncing lead activity to CRMs, triggering alerts on delivery failures, and building multi-channel outreach workflows.

Output Data

Each delivery produces one output item. The Lemlist payload is placed directly on the item alongside three metadata fields:

{
  "_trigger": "lemlist_webhook",
  "_timestamp": "2026-01-01T00:00:00.000Z",
  "_webhookEvent": "emailsOpened",
  "type": "emailsOpened",
  "campaignId": "cam_abc123def456",
  "campaignName": "Test Campaign",
  "leadId": "lea_abc123def456",
  "sequenceId": 1,
  "sequenceStep": 1,
  "email": "prospect@example.com",
  "firstName": "John",
  "lastName": "Doe",
  "companyName": "Example Corp",
  "sendDate": "2026-01-01T00:00:00.000Z",
  "openDate": "2026-01-01T00:00:00.000Z",
  "isFirst": true
}

• _trigger — always lemlist_webhook.
• _timestamp — ISO 8601 timestamp of when the delivery arrived.
• _webhookEvent — the event name, copied from the payload’s type field, or unknown when it is absent.
• The remaining fields come straight from Lemlist and vary by event: lead identity (leadId, email, firstName, lastName, companyName), campaign context (campaignId, campaignName, sequenceId, sequenceStep) and event-specific timestamps such as sendDate and openDate. isFirst marks the first occurrence of that activity for the lead.

Reference values downstream by expression, for example {{ $json.email }} or {{ $json.campaignName }}.

Example Configuration

Fire on every email open:

{
  "type": "lemlist_trigger",
  "parameters": {
    "event": "emailsOpened"
  }
}

Fire on replies within one campaign:

{
  "type": "lemlist_trigger",
  "parameters": {
    "event": "emailsReplied",
    "options": {
      "campaignId": "cam_abc123def456",
      "isFirst": false
    }
  }
}

Fire only the first time a lead accepts a LinkedIn invite:

{
  "type": "lemlist_trigger",
  "parameters": {
    "event": "linkedinInviteAccepted",
    "options": {
      "isFirst": true
    }
  }
}

Qualify interested leads from one campaign, once per lead:

{
  "type": "lemlist_trigger",
  "parameters": {
    "event": "emailsInterested",
    "options": {
      "campaignId": "cam_qualification001",
      "isFirst": true
    }
  }
}

Watch for connection issues and send failures:

{
  "type": "lemlist_trigger",
  "parameters": {
    "event": "connectionIssue"
  }
}

Receive every Lemlist event:

{
  "type": "lemlist_trigger",
  "parameters": {
    "event": "*"
  }
}

Trigger Behavior

• Activation: When the workflow is activated, a webhook endpoint is registered with the service.
• Deactivation: The webhook is automatically unregistered when the workflow is deactivated.
• Payload: The incoming webhook payload is parsed and output as workflow items.
• Verification: Supports signature verification where applicable.

Tips

This tool receives notifications from Lemlist when outreach events occur. It is ideal for automating workflows based on prospect engagement, rather than sending emails or managing campaigns directly. The tool produces a webhook payload containing lead and activity details from Lemlist.
