Create a pop-up contact sign-up form for your website

How can I add the universal code for a pop-up subscription form to a Wordpress.com site?

Hello @RachaelM301 ,

Wordpress.com doesn't support 3rd party Javascript or plugins of any kind. If you're using Wordpress.com, we recommend creating a Landing Page Sign-up Form. You can then copy the Landing Page's URL and link it to a button or text link on your Wordpress.com website.

Otherwise you can also utilize the integrated plugin developed for Wordpress. Please keep in mind that this integration will have its own support team, separate from our general support.
