Acknowledgment or auto-reply emails are sent to the sender of emails that JIRA picks up to create issues or comments. It is a useful helpdesk/service desk feature that assures your customers or partners that their request has been processed and recorded correctly.

There a few alternative solutions to configure auto acknowledgment in JETI:

Auto-Reply with JETI Mail Handler

JETI Mail Handler is a component that can not only pick up emails from an email account and create issues or comments from the emails. But also it has a lot more features, including sending auto reply emails back to the sender. Steps to do:

You're done. This is the simpliest and dedicated solution. Auto-reply will be sent for the next incoming email that is processed by JETI's mail handler.

Auto-reply emails are sent upon incoming emails only. When issues are created manually, emails are not sent.

Auto-Reply with JETI Notifications

If you don't want to use JETI Mail Handler to send automatic acknowledgment emails, you can use JETI Notifications.  When JIRA creates an issue from an incoming email, an internal Issue Created event is thrown.

This event can be handled by a JETI Notification Template to send the auto-reply email.

Steps to do:

If the above is complete, auto-acknowledgment emails will be sent next time an issue is created.

This solution does not only send auto-reply emails when an incoming email is processed but also when an issue is created manually. As JIRA obviously throws Issue Created in this case too.

Auto-Reply with JETI Post-function

If you don't want to use JETI Mail Handler or JETI Notifications to send automatic acknowledgment emails, you can still use JETI Post-function.  

Steps to do:

If the above is complete, auto-acknowledgment emails will be sent next time an issue is created.

This solution does not only send auto-reply emails when an incoming email is processed but also when an issue is created manually. As JIRA obviously throws Issue Created in this case too.
