Adding a newsletter subscribe option to checkout

You can encourage customers to subscribe to a newsletter at checkout by connecting it to Email Campaigns or a Mailchimp account. This adds a Join our mailing list checkbox below the email field on your checkout page.

The subscribe option is a great way to build your mailing list, increase customer loyalty, and encourage repeat purchases.

The information in this guide also applies to donations checkout.
