Mailchimp integration for Ninja Forms 3

Published on by

Yesterday, we released Mailchimp for WordPress version 4.1. This plugin update adds renewed support for the latest & greatest Ninja Forms 3, a popular form builder plugin.

We've been maintaining an integration for the older Ninja Forms plugin for a little over 2 years already. Because Ninja Forms 3 is basically a complete rewrite, we had to redo our integration as well. Not for nothing though, the result is a huge improvement over the older integration.

So, if you want to subscribe from Ninja Forms 3 to your Mailchimp lists, you're in luck.

Subscribing from Ninja Forms to Mailchimp

The first thing to do is to open up one of your Ninja Forms, go to Emails & Actions and add the Mailchimp action to your form. This action subscribes the person filling out the form to a Mailchimp list of your choice. The action settings allow you to configure the following things:

  • The Mailchimp list to subscribe to.
  • Which form fields map to which Mailchimp list field. Your Mailchimp fields will automatically be pulled-in after selecting a list to subscribe to.
  • Whether to use double opt-in (email confirmation) or not.
  • Whether to update existing subscribers.

To subscribe to multiple Mailchimp lists from the same form, simply add the action to your form more than once.

Adding an opt-in field

In its current state, the Mailchimp action subscribes everyone that fills out the form. To only subscribe people that opt-in to being subscribed, you have to add a checkbox field to your form. We've included a helpful "Mailchimp opt-in" field for this.

Once included in your Ninja Forms form, the Mailchimp action only triggers if the "Mailchimp opt-in" field is checked.

Don't be a Ninja

We provide the Ninja Forms 3 integration for free and hope you like it. If you do, please do not be a silent ninja about it and leave a plugin review on WordPress.org. We really appreciate getting these!

If you run into an issue with the integration, make sure to let us know through the plugin's support forum on WordPress.org.
