What this integration does
The MailerLite connector listens for member signup. It upserts the new member as a subscriber, sets their name from their display name when available, and — if you configure a group ID — assigns them to that group. If a member account is deleted, or a reader clicks the HMAC unsubscribe link, the connector unsubscribes the matching MailerLite subscriber rather than deleting them, so their subscriber history in MailerLite stays intact while mail stops going out. Every call is fail-soft: a MailerLite API error is logged and never blocks the signup, delete, or unsubscribe flow it's attached to. It is a one-way push from VeloCMS to MailerLite — campaigns and automations run entirely inside MailerLite.
