People often use MailChimp for their mailing list whenever they want their WordPress site visitors to subscribe to their MailChimp list. You can use a popup form or a traditional signup form. You can link to your MailChimp account and choose your desired audience list. Suppose there are categories in the audience list. In that case, you can specify default preferences for members or view interests in the email subscription type, such as checkboxes, radio buttons, or drop-downs. 

Step by Step Process

The first time the user activates it, the subscriber popup page can be interactive since it displays on top of your website. Here's how to add MailChimp popup to WordPress.

  • Step One: Create a Form in MailChimp

As soon as visitors open your tab, it is appealing to configure your form to show a popup. Settings must ensure that the popup flashes out after 5 seconds instead of instantly. Visitors will see the MailChimp form once available. Ensure that they get more time to acquaint themselves with your site. They are more likely to apply to your email list.  

  • Step Two: Connect Your Site to MailChimp
  1. You will see a popup Linking your site to display your popup on your site when building your form. Click on Connect Now. Furthermore, this option.

Whenever a visitor comes to your site for the first time, they will see a popup message along with your subscription form. Make sure to turn ON the popup so that it starts to be displayed at your site. However, in the visitor's browser, a cookie is stored so they will not get the popup again.


Update Your Form

If you would like to make improvements to your form, go back to the MailChimp settings to make the modifications. They will immediately be mirrored as soon as you post those updates to the MailChimp form when the popup is displayed to the next user to your site. You do not need the code to be copied/pasted again!

Points to Remember

The popup form for MailChimp signup is configured with some functionality to check:

  • If a person has already subscribed or pressed the Close button, it does not show the form anymore. 
  • The cookie blocks the display of the popup again! 

If you'd like, you can remove the cookies to find out if the website is running fine.
