Easy Digital Downloads Conditional Emails Addon
Conditional Emails allows you to create automatic emails that are sent when certain events occur. For example, you can easily create an email that is automatically delivered to the customer when a new pending purchase record is created, or you could create an email that goes to your site administrators anytime a payment’s status is changed.
At this time the extension supports sending emails during payment status changes but will include support for additional actions in the future.
Note that this extension is not recommended for cart recovery. If you are looking for cart recovery options you may be interested in Jilt or Zapier.
