Spin CRM

MailerLite

Subscriber lists mapped both ways: new subscribers travel to the platform, and unsubscribes and bounces come back.

What this integration does

  • New subscribers travel to the MailerLite list
  • Unsubscribes and bounced addresses come back to the CRM
  • A negative status always wins — a sync never brings back someone who has opted out
  • The same works with Omnisend

How it is connected

No programming is needed. You enter the login details yourself, so they stay with you, and every data exchange is visible in the integration log with a timestamp, the response and the reason for any error.

  1. 01

    You take the MailerLite API key from your account

  2. 02

    You enter the key in the settings and map the lists

  3. 03

    The first mapping happens immediately, and after that on a schedule

Where you will see it in the system

An integration is not a separate window — it changes what you see in your daily work. These are the areas where the change is biggest.

FAQ

Questions about this integration

Did not find your answer? Ask us

Can we keep sending emails from MailerLite?

Yes. The emails are sent from the platform, and the lists match both ways.

What happens when someone unsubscribes on the platform?

The unsubscribe comes back to the CRM and becomes a negative status that neither an import nor a colleague can undo — only the person themselves.
