Newsletter signup forms for any site

Add signup forms that subscribe people to Mailchimp or Kit directly — styled exactly like your site.

Add signup forms that subscribe people to Mailchimp or Kit directly — styled exactly like your site.

How it works

Use the newsletter signup template, post it to FormSubmit, and connect the Mailchimp or Kit integration with your API key.

Why not the provider's embed?

Provider embeds bring their own scripts and styles. A headless form keeps your design and page speed, while FormSubmit filters bots before they pollute your list.

Double opt-in

Enable Mailchimp double opt-in, or add subscribers to a Kit form that triggers your welcome sequence.
