Restrict Content Pro – MailChimp


On October 14th, 2021, Restrict Content Pro MailChimp will be removed from the WordPress plugin repository.

The plugin is no longer necessary now that all Restrict Content Pro plans include the Mailchimp Pro.

MailChimp Pro and all other Restrict Content Pro add-ons will remain available to download in your iThemes Member’s Panel.

This is an add-on for the Restrict Content Pro plugin. It does not function on its own.

This plugin will add a MailChimp Newsletter signup option to the member registration form in Restrict Content Pro.
