Set to complete when due date passes

[Elena Luna]

Hi everyone :) 

My team is running a campaign project and we have set the due dates of the child issues to be the dates a specific email is to be sent. 

These emails are built and delivered on another platform - however as we have used the due dates as essentially the "sent date" we were hoping that once the due date occurs, the status of that child issue can be set to 'complete' as it would have already been sent. 

Is this possible through automation? I have looked at the scheduling rule however I am not familiar enough with JQL to run it. 

Thank you

Hi Elena, welcome to the Atlassian Community,

Using the scheduled trigger in Jira automation is a valid way to do it.
Use this JQL filter in the trigger:

duedate < now() and status != complete

It will only perform the automation rule for issues where the duedate is the past and the status has not been set to complete yet.
Setting the rule to run once a day is probably enough.
