MailerLite

Add a contact to your MailerLite audience with their email, name, and any custom field values the agent captures upstream.

Update a MailerLite subscriber's email address while preserving their group memberships, custom fields, and engagement history.

Create a new named group in MailerLite so the agent can immediately start adding subscribers and assigning automations to the fresh segment.

Remove a subscriber from a specific MailerLite group, stopping any group-triggered automations without deleting or unsubscribing the contact.

Trigger immediate delivery of a MailerLite campaign that is already in draft — the final send command the agent issues when all conditions are met.

Fires via webhook when a subscriber marks a MailerLite campaign as spam, requiring the agent to take immediate action before repeat complaints damage sender reputation.

Fires when a MailerLite campaign email bounces for a subscriber, allowing the agent to suppress, investigate, or correct the address before it degrades list health further.
