Frequently Asked Questions

Can I use any form to connect to Mailchimp from WordPress?

You can connect to Mailchimp from WordPress with any form just by adding a Mailchimp action to that form. Start from scratch, a Mailchimp signup form template, or use any existing Ninja Forms on your WordPress website!

Can I make a Mailchimp signup form using any Audience or Group?

You will set the Audience yourself, and the form will sync with all features of that Audience, including any Groups, tags, or fields you have set up in your Mailchimp account.

What type of support is available to Ninja Forms customers?

We have a dedicated support team standing by to help with anything you may need. We’re available 9am-4pm EST, Mon-Fri, and strive to answer all customer requests within 24 hours.

How do Ninja Forms licenses work?

Licenses are subscription based and will auto-renew each year unless cancelled. If cancelled, you may still use your extensions but will no longer receive important updates or support once the license expires.

We don’t have a demo or trial version of our add-ons, but we do offer a 14 day full refund policy for any reason whatsoever.
