How to connect Convertful with MailerLite

With Convertful you can easily integrate your account with MailerLite and use widgets to grow and segment your mailing list. Just follow the guide below to set up MailerLite integration and set up relevant actions.

Connecting Integration #

In your site’s Integrations tab, add new integration by choosing MailerLite from the list. It will request your API key, which you can find in your MailerLite's Integrations section, Developer API page:


Fill in the credentials and press the Connect button.

Default Settings #

Once MailerLite is connected, by default, each widget will automatically add subscribers with the default settings that you specify in the integrations’ settings.


Note, that default settings are not mandatory and you can always specify custom lists and tags manually for each specific widget while editing its button's actions.

Mapping Custom Fields #

We try to find the most relevant MailerLite custom field for every Convertful field automatically. But if you need to fine-tune which fields we should use, you can do this in the integration settings, by editing Custom Fields list:


Actions #

When editing your widget's button, inside its settings you can see “On Submit Actions” / “On Click Actions” which you can use to perform actions provided by MailerLite integration: 

  • Add subscriber with default settings
  • Add subscriber to group
  • Remove subscriber from group
  • Update custom field

When updating custom fields you can send the dynamic data to the integration:
