I have raised this in a zoho chat session, and there was no solution. So I am posting the idea here.

Please add a facility to workflow to not notify the current operator via email of any actions that the operator themselves has carried out. 

Scenario 1:

i do not need an email to tell me that I have just assigned a job to me - but I do want to know if another operator assigns me a job

Scenario 2:

I do not need an email to tell me that I have just logged a new ticket for someone - cos I just logged it!

------------

Please implement this soon!  I am fed up of cleaning my email up of actions that I know I just did!
