More documentation

More detailed documentation can be found in the MailChimp for WordPress knowledge base.

How to display a form in posts or pages?

Use the [mc4wp_form] shortcode.

How to display a form in widget areas like the sidebar or footer?

Go to Appearance > Widgets and use the MailChimp for WP Form widget that comes with the plugin.

Where can I find my MailChimp API key?

You can find your MailChimp API key here

How to add a sign-up checkbox to my Contact Form 7 form?

Use the following shortcode in your CF7 form to display a MailChimp sign-up checkbox.

[mc4wp_checkbox "Subscribe to our newsletter?"]
The form shows a success message but subscribers are not added to my list(s)?

If the form shows a success message, there is no doubt that the sign-up request succeeded. MailChimp could have a slight delay sending the confirmation email though, please just be patient and make sure to check your SPAM folder.

When you have double opt-in disabled, new subscribers will be seen as imports by MailChimp. They will not show up in your daily digest emails or statistics. We always recommend leaving double opt-in enabled.

How can I style the sign-up form?

You can use custom CSS to style the sign-up form if you do not like the themes that come with the plugin. The following selectors can be used to target the various form elements.

.mc4wp-form { ... } /* the form element */
.mc4wp-form p { ... } /* form paragraphs */
.mc4wp-form label { ... } /* labels */
.mc4wp-form input { ... } /* input fields */
.mc4wp-form input[type="checkbox"] { ... } /* checkboxes */
.mc4wp-form input[type="submit"] { ... } /* submit button */
.mc4wp-alert { ... } /* success & error messages */
.mc4wp-success { ... } /* success message */
.mc4wp-error { ... } /* error messages */

You can add your custom CSS to your theme stylesheet or (easier) by using a plugin like Simple Custom CSS

I’m getting an “HTTP Error” when trying to connect to MailChimp

If you’re getting an HTTP Error when trying to connect to your MailChimp account, please contact your webhost and ask them if they have PHP CURL installed and updated to the latest version (7.40.x).
Also, please ask them to allow requests to https://api.mailchimp.com/.

How do I show a sign-up form in a pop-up?

We recommend the Boxzilla pop-up plugin for this. You can use the form shortcode in your pop-up box to show a sign-up form.
