The right tools can make all the difference.

And that's why we'll use the best WordPress form plugin, Formidable Forms, for this step-by-step tutorial.

With this form builder and its Mailchimp WordPress integration, we can make our Ajax forms in WordPress and instantly connect them to our Mailchimp account.

In fact, this powerful combo can do a lot when it comes to Ajax and Mailchimp forms:

  • Automatically apply Mailchimp tags to new and updated subscribers.
  • Create Ajax multi-step forms.
  • Choose between single or double opt-in for Mailchimp subscribers.
  • Add users to a Mailchimp list or audience on form submission.
  • Use a form field to subscribe users to different Mailchimp groups.
  • Trigger email drip campaigns set up in your Mailchimp account.

Using these features, you can create Mailchimp contact forms and a lot more โ€” of course, Ajax-ready! It's not one-size-fits-all either. You can easily add a Mailchimp signup checkbox to a contact form, or any form you want to.

So if you want to submit a form without a page refresh (aka using Ajax), we can do this easily. Let's get to it!

    Step 4: Configure Mailchimp Ajax settings and form actions

    Here's where it all comes together.

    First, let's make sure our form has Ajax enabled. To do that, click on the Settings tab at the top of the builder. Then tick these three boxes:

    We weren't kidding when we said this would be easy! โœ… Now, let's connect the form to our Mailchimp account.

    We'll do this by opening the Actions & Notifications panel and adding the Mailchimp form action.
