Advanced Form Integration plugin allows you to integrate any Sender Platform to Mailchimp. When a user fills a form on your website, the plugin will send the data to your Mailchimp account and create a contact in the preferred audience. You can also add custom merge fields and tags.

Supported Features

  • Free: Create a new contact with all basic (First Name, Last Name, Email) fields. It also allows adding the contact to a preferred list.
  • Paid: Additionally supports custom merge fields and tags.

Create New Integration
