How to send an email to say assignee via automation every 4hrs until the issue is closed

How to send an email to say assignee via automation every 4hrs until the issue is closed. 

The scheduled option is based on a set schedule and cannot be used for individual issue's create date. 

For eg - If I have scheduled an email for 2PM , 6PM , 10PM .. and an issue is created at 4PM .. in the 6PM batch it wont be picked as it has been only 2 hrs since issue is created . It will be picked in 10pm batch . however, it means that it would be 6hrs since the issue was created and that is not what I am looking for. 

If anyone has a solution for this please help.

Hi @apai ,

Welcome to the Atlassian Community!

You can use the corn expression for the rule trigger every 2 hours. You can use the below website to create a corn expression.

Example- for 2 hours every day

0 0 0/2 ? * * *

Hi @apai , and Welcome to the Community, glad you're here!

To follow on what @Manoj Gangwar suggested (with apologies if you're familiar with cron scheduling expressions), you might also look at the Community article Constructing cron expressions for a filter subscription. It provides a breakdown of how a cron expression is actually built and definitions of the common characters you can use to manipulate it (such as /, *, - and so on).

Using the chart above, you would use the cron expression

0 0 0/4 ? * MON-FRI *

to send the Assignee an email starting at 0 seconds of 0 minutes of hour 0 (midnight, or 12AM, the 0 of 0/4) every 4 hours (the 4 of 0/4) on any day of the month of every month on weekdays of every year. If you wanted to start sending emails at 6AM or 1PM, you'd just change it to

0 0 6/4 ? * MON-FRI *  OR  0 0 13/4 ? * MON-FRI *

If you plug that expression into the utility that Manoj referenced, the text interpretation would be "At second :00, at minute :00, every 4 hours starting at 00am, every day between Monday and Friday, every month". Note that there's not a character for year because we've indicated that it's every month (with no end).

Hope this helps!
