MailerLite
Use Meshes to add subscribers to MailerLite groups or remove them from groups from product events.
Use the MailerLite integration when Meshes should manage subscriber group membership based on product behavior. In a Meshes workspace, you create the MailerLite connection, build a rule for the event you care about, and select the MailerLite group the rule should use.
Supported actions
- Add to Group adds the subscriber to a selected MailerLite group.
- Remove from Group removes the subscriber from a selected MailerLite group.
Create the connection
- Open Connections in your Meshes workspace.
- Click New Connection.
- Select MailerLite.
- Give the connection a clear name.
- Enter the API Token from MailerLite.
- Save the connection.
You can find the MailerLite API token in Integrations -> API.
Create a rule
- Open Rules and click New Rule.
- Select the event type that should trigger the MailerLite action, such as
user.signuporsegment.left. - Select the resource type for that event.
- Choose your MailerLite connection.
- Select Add to Group or Remove from Group.
- Choose the MailerLite group.
- Map the event fields Meshes should send to MailerLite.

The mapping catalog includes email, ip_address, built-in MailerLite subscriber fields, and the custom fields available in the connected account.
Send a test event

Use Send Test Event on the rule to verify the selected action and mappings.
