For a long time I just kept creating triggers and automations... and then one day I looked up and we had almost 100 of them. Even though they were named uniquely, they were difficult to find and troubleshoot in that long list.
So what I did just recently was to coded them starting the triggers with "T001" and automations with an "A001". So, for example, the second trigger is T002 and the thirty-third automation is A033. While re-naming these, I also tacked that code on to the end of any email messages that was a part of those triggers and automations.
Now, when anyone gets a strange email, I just ask them for the code at the very bottom of the email and I can easily trace it back to the correct trigger or automation. This also works when viewing the events of a ticket.
One note of caution: don't re-use your codes. If you ever stop using a trigger or automation, just retire that code and use a new one.
