Use the Actions By Email package to send emails automatically during your Processes' Requests.
The Actions By Email package has the Actions By Email connector that integrates into Process Modeler. Use the Actions By Email connector as you would BPMN elements: drag and place the Actions By Email connector into your Process model, configure its settings, and then add its incoming and outgoing Sequence Flow elements.
When the Actions By Email connector triggers during an in-progress Request, ProcessMaker sends an email from the "email@example.com" email address to one email recipient so that this Request participant can make a decision as part of the Request. For example, this Request participant must make a decision to approve or deny a vacation request or for a purchase. The email recipient receives an email with buttons in the email to easily indicate the decision.
After the email recipient clicks a button to indicate the decision, ProcessMaker receives the response and uses the indicated decision as part of the Request routing. For example, if you grant a leave request, the Request routes differently than if you deny that leave request.
