The success of your mailing lists depends on finding the right Mailchimp integration for WordPress. With literally hundreds to choose from on WordPress.org alone, finding the right one for you can be a monumental decision!
- Don’t like being locked in to a specific look and feel?
- Feeling limited by what your integration can do?
- Just don’t have the options you need to make the signup form you want?
Your Mailchimp integration for WordPress should eliminate each of those common pains. You’ve just found the one that will!
Experience simplicity without sacrificing features
This add-on has been tailor-made to perfectly integrate Mailchimp and WordPress via your WordPress forms. Effortlessly:
- Place unlimited signup forms anywhere you need them.
- Collect any information you need for all your Lists and Interest Groups!
- Customize your signup form’s presentation.
- Enable double opt-in per form.
- Send or display confirmation of submission.
Even leverage the extended features of other Ninja Forms extensions to:
- Conditionally add users to specific Lists and/or Interest Groups based on their preferences.
- Fine-tune the styling of your WordPress signup forms with minimal knowledge of CSS.
- Trigger a variety of other actions for any new signup.
Mailchimp Integration for WordPress does not get any easier than this
Getting your Mailchimp account synced with WordPress is simple — we’ll walk you through the process! After installing the add-on, you’ll find a ready-made Mailchimp signup form set to go. You can then use that form to begin, choose another existing form, or create a custom Mailchimp signup form for WordPress.
Set up Ninja Forms to work with Mailchimp Signup Forms
Before setting up the Ninja Forms Mailchimp add-on, you must obtain a new or existing Mailchimp API Key in the API Keys section of your Mailchimp account.
- Go to your Ninja Forms settings and scroll to the bottom to access MailChimp.
- Copy your API key from Mailchimp and paste it into the Mailchimp settings.
- Go to Ninja Forms Dashboard, click on Add New, and choose one of the forms templates for Mailchimp Signup.
- Select your Mailchimp audience list, name the form, and click Create.
Manually add a Mailchimp action to your form
Syncing any form to your account is simple and allows information to flow with every submission.
- Go to Emails & Actions > Add New Action > Mailchimp.
- Choose the Mailchimp list you want the data saved to.
- Use Merge tags to map the fields from your form to the corresponding Mailchimp list. Add tags in a comma-separated list, if any, and choose your interest groups for your list.
The Mailchimp Opt-In field and how it works
The Mailchimp Opt-In field is a special field type that gives users a choice to be added to your Mailchimp list without requiring complex conditional logic. To add it:
- Click the blue “Add Field” button in your form builder.
- Select “Mailchimp Opt-In” from the field options.
- Users who check this field are added to your list. If unchecked, the Mailchimp action will be ignored.

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 with 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.
My Mailchimp lists aren’t showing up in Ninja Forms. What should I do?
If your lists don’t appear after adding your API key, you can refresh the list by clicking the refresh icon located beside the “List” label in the Mailchimp action settings. Refreshing will fetch the latest lists from your Mailchimp account.
Why aren’t my form submissions being added to my Mailchimp list?
The most common reason is missing required fields. If a field is marked as required in your Mailchimp list, it must be mapped to a corresponding field in your Ninja Forms form. Mailchimp will reject the submission without this mapping, and the contact won’t be added to your list.
How do I ensure users only join my list if they want to?
There are two approaches:
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.
Can I get a demo or trial of Ninja Forms add-ons before I buy?
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.
