Cart66 is an easy-to-use, light-weight e-commerce plugin for WordPress. Our non-profit uses it to take online registrations for classes, memberships, and donations. During the payment process, customers enter their email address so that they can receive a digital receipt. I wanted a way to capture this email and add it to a Mailchimp list (if you don’t know about Mailchimp — it’s one of the best platforms for sending e-newsletters). Cart66 offers an integration with Mailchimp (for the Pro version of Cart66) — however, their method asks the customer if they want to join the list during the checkout process and only works with Paypal Express. I wanted to keep the checkout process as simple and hassle-free as possible, so I decided to create a plugin that would automatically send the email address to Mailchimp when the transaction is complete. If the user is not already on the list, they will receive an email from Mailchimp to confirm whether they want to receive the newsletter.
