Frequently Asked Questions
Common questions about MC4WP: Mailchimp for WordPress
You can find your Mailchimp API key here
Use the [mc4wp_form] shortcode or the Gutenberg block.
Go to Appearance > Widgets and use the Mailchimp for WP Form widget that comes with the plugin.
Use the following shortcode in your CF7 form to display a newsletter sign-up checkbox. [mc4wp_checkbox "Subscribe to our newsletter?"] Our knowledge base has more information on connecting Contact Form 7 and Mailchimp.
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 check again in a few minutes (sometimes hours) and don't forget to check your junk folder too. 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.
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
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.
You can use our WooCommerce integration for that. How to subscribe to Mailchimp from the WooCommerce checkout form.
You can find instructions for connecting your WooCommerce store with Mailchimp on our website. I'm getting an "HTTP Error" when trying to connect to Mailchimp. the "HTTP Error" type is usually because of a firewall configuration issue or outdated software on your web server. Please contact your webhost and ask them to check the following: Whether remote HTTP requests to https://api.mailchimp.com are allowed. Whether cURL and the PHP-cURL extension are installed and updated to a recent version.
Please report security bugs found in the source code of the Mailchimp for WordPress plugin through the Patchstack Vulnerability Disclosure Program. The Patchstack team will assist you with verification, CVE assignment, and notify the developers of this plugin. My question is not listed here. Please search through our knowledge base.
