How this automation works

Receive real-time Slack alerts for new MailerLite subscribers. This Applet runs whenever MailerLite adds a new subscriber (you can optionally limit it to a group) and posts a customizable message to the Slack channel you choose. It's ideal for sales, support, or marketing teams who want to act on signups quickly and keep team members informed via Slack and MailerLite. Note: Customize the message to fit your tone.
