Description

EDD Campaign Monitor
Automatically add customers to a Campaign Monitor list during checkout.
This add-on will add an option to the checkout page that allows users to signup for your newsletter at the same time as purchasing. As just a simple checkbox, this is guaranteed to create more newsletter sign ups than a regular subscribe form placed elsewhere on your site.
In the Extensions section of the Easy Digital Downloads Settings, you will have options to enter your Campaign Monitor API key, enter a Client ID, choose the email list to subscribe users to, and an option to define the checkout field label.
