Tasks

There is a built-in Tasks component RequestApprovalEmail. This component is more like a template, something you can use and built your own version that better fits into your platform. Although, even this component may be useful.

This component sends one email to the requestor and another email to the approver. It uses Appmixer Mandrill account to do that. Those emails contain a few Appmixer related information - Reply To, From Email, ... These can be configured using Backoffice.

Possible configuration for RequestApprovalEmail component.
