Send a Mattermost Message When a Lemlist Lead Replies

This n8n workflow automates the process of notifying your team on Mattermost whenever a lead replies to your email campaign in Lemlist. It helps keep your team instantly informed about engaged leads, enabling quicker follow-ups and improved lead management.

What it does

1. Listens for Lemlist Replies: The workflow is triggered whenever a lead replies to an email campaign in Lemlist.
2. Posts to Mattermost: It then sends a message to a specified Mattermost channel, alerting your team about the new lead reply.

• Lemlist Account: With an active email campaign and leads.
• Mattermost Account: With access to a channel where notifications should be posted.
