plugin, it finally is._

good looking and accessible sign-up forms or integrate with any other existing form
on your WordPress site, like your contact, comment or checkout form.

* Connect with your Mailchimp account in seconds.
* Sign-up forms which are good looking, user-friendly and mobile optimized. You
have complete control over the form fields and can build your forms using native
HTML.
* Naadloze integratie met de volgende plugins:

use our [custom integration](https://www.mc4wp.com/kb/subscribe-mailchimp-custom-html-form/)
feature. Alternatively, the plugin comes with a PHP API to programmatically add
a new subscriber to Mailchimp.
* [Mailchimp for WordPress Premium](https://www.mc4wp.com/): stuurt je WooCommerce
bestellingen naar Mailchimp, zodat je precies ziet wat elke inschrijver gekocht
heeft en hoeveel opbrengst je e-mail campagnes genereren.
* Een groot aantal beschikbare add-on plugins en integraties:
- [Mailchimp for WordPress Premium](https://www.mc4wp.com/)
- [Mailchimp Top Bar](https://wordpress.org/plugins/mailchimp-top-bar/)
- [Boxzilla Pop-ups](https://wordpress.org/plugins/boxzilla/)
* Well documented through our [knowledge base](https://www.mc4wp.com/kb/).
* Developer friendly. For some inspiration, check out our [repository of example code snippets](https://github.com/ibericode/mailchimp-for-wordpress/tree/main/sample-code-snippets).
* Geschikt voor PHP 8.5, maar achterwaarts-compatibel helemaal terug tot PHP 7.4.

## FAQ
### Where can I find my Mailchimp API key?
You can [find your Mailchimp API key here](http://kb.mailchimp.com/accounts/management/about-api-keys#Find-or-Generate-Your-API-Key)
### How to display a form in posts or pages?
Use the `[mc4wp_form]` shortcode or the Gutenberg block.
### 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.
### How to add a sign-up checkbox to my Contact Form 7 form?
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](https://www.mc4wp.com/kb/subscribe-mailchimp-contact-form-7/).
### 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 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](http://blog.mailchimp.com/double-opt-in-vs-single-opt-in-stats/).
### 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](https://wordpress.org/plugins/simple-custom-css/#utm_source=wp-plugin-repo&utm_medium=mailchimp-for-wp&utm_campaign=after-css-link)
### How do I show a sign-up form in a pop-up?
We recommend the [Boxzilla pop-up plugin](https://wordpress.org/plugins/boxzilla/)
for this. You can use the form shortcode in your pop-up box to show a sign-up form.
### How do I subscribe from my WooCommerce checkout form?
You can use our WooCommerce integration for that. [How to subscribe to Mailchimp from the WooCommerce checkout form](https://www.mc4wp.com/kb/connect-woocommerce-store-mailchimp/).
### How to connect my WooCommerce store with Mailchimp?
You can find instructions for [connecting your WooCommerce store with Mailchimp](https://www.mc4wp.com/kb/connect-woocommerce-store-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.
### Where do I report security bugs found in this plugin?
Please report security bugs found in the source code of the Mailchimp for WordPress
plugin through the [Patchstack Vulnerability Disclosure Program](https://patchstack.com/database/vdp/8c215d34-dc57-4167-8af8-a9863cb63668).
The Patchstack team will assist you with verification, CVE assignment, and notify

[nschouinc](https://profiles.wordpress.org/nschouinc/) 12 juli 2026
Connected my list in a few minutes, forms match my site's styling without extra
tweaking, and double opt-in works as expected. No complaints so far.
### [Easy to use and beautiful too](https://wordpress.org/support/topic/easy-to-use-and-beautiful-too/)
[De Harris](https://profiles.wordpress.org/allbizweb/) 25 juni 2026
We have been using MC4WP for almost a year now, and I am so pleased how it has been
working for us. It was easy to integrate and set up. No issues, so I highly recommend
you use it for your site.
### [Perfect](https://wordpress.org/support/topic/perfect-11004/)
[Nonos](https://profiles.wordpress.org/nonos/) 9 juni 2026
Clean, stable and updated regularly
### [Great Plugin & Support](https://wordpress.org/support/topic/great-plugin-support-414/)
[James](https://profiles.wordpress.org/james-feaver/) 16 april 2026
I've been using this for a long time to add subscribers to Mailchimp both on a form
and in the Woocommerce checkout. I recently encountered a problem experimenting
with the Woocommerce block-based checkout and M4CWP support were great. Highly recommended
plugin.
### [Not Bad Option](https://wordpress.org/support/topic/not-bad-option/)
[Reyna](https://profiles.wordpress.org/reyna20/) 8 april 2026 1 reactie
Tried Mailchimp for WordPress for my forms. It connects fine and does the basic
job. But the setup felt a bit confusing at times. Works ok overall, but could be
simpler and smoother.
