Hey there MaryElla,
Thanks for posting! MailChimp provides a handful of options to help design a signup form. Some require knowledge of CSS/HTML, while others do not!
To start, it’s worth noting that this WordPress plugin does provide a few options for styling certain parts of your sign up form. To check out the available options, you’ll want to take a look at your plugin’s settings, which will provide a few ways you can customize certain text, as well as colors on your sign up form. If you’re not seeing the aspect of your signup form as an editable option here, ultimately changing the design of the plugin signup form will required adding CSS code to your WordPress theme’s stylesheet. This process will require knowledge of constructing CSS code.
If there’s any particular aspect of the form that you’re looking to change, feel free to post a description of what you’re looking for and I’d be happy to help. While we’re limited in the amount of custom code help we can provide here, I’d be happy to help to get you started in the right direction.
Alternatively, you may consider options outside of this plugin form. For example, in your MailChimp account you have the ability to use our form builder to style your MailChimp-hosted signup form. Once you’ve done that, you can simply add a link to your MailChimp-hosted signup form, to your WordPress site. More info on that is available in our KB here!
