Process Manager uses e-mail to make assignments, request approvals, and notify designated participants, in order to facilitate effective communication and continual progress toward completion of workflow processes. You can create and then apply customized e-mail templates to specific actions so every occurrence of that action will cause Process Manager to send a pre-formatted e-mail to the designated recipients.
E-mail templates serve an important role for providing the functionality that allows participants to approve or deny a change request directly from the e-mail itself. To enable this, you apply an e-mail template to an action and then select the Send e-mail using HTML option in order for the approval controls to appear in the e-mail message.
