Integrating your form with MailerLite

By integrating your form with MailerLite, you can add any submissions you receive straight to MailerLite as a subscriber.

This article will explain how to integrate your form with MailerLite.

* Note: to integrate a form with MailerLite you MUST collect an e-mail address.


On step 3 ('Sync') of the form wizard when editing or creating a form, choose MailerLite from the list of available integrations.


A button will appear telling you to add a MailerLite account. Click it and a form will appear. (If you have already added an account, a drop down menu will appear asking you to choose which MailerLite account you would like to use.)


The form has a couple of fields:

  • Name - This is just for your reference so you can separate one account from another.
  • API Key - Your MailerLite API key. To find your API key, follow these instructions.

Once you are ready, click 'Go'. A new set of options will appear:


These options are:

  • Which MailerLite Account? - A dropdown menu allowing you to choose which MailerLite account you would like to use (if you have more than one).
  • List - A dropdown menu to choose which client from your MailerLite account holds the list you wish to add subscribers to. This will automatically populate with the lists in your MailerLite account.

If you change any of these values they will automatically save.

Beneath these options you will find the field mappings:


On the left is the field as it is in CreateForm, in the dropdown menu is the field you want to link to in MailerLite. CreateForm will try to map certain fields automatically, but you will need to check that these are correct.

If you have a custom field in MailerLite which you wish to use instead of the pre-made fields, click the 'Add' button for the CreateForm field you want to send to MailerLite. A form will appear:


Give the field the same name as your custom field in MailerLite, then click 'Add'. Do this for each custom field you have.

That's it! Your form is now integrated with MailerLite. Because each form and each MailerLite account is different, we highly recommend that you test the integration by filling out your own form several times to ensure all the data goes to the place you want it.
