    hi everyone. I would like to know if I can stop receiving same email.

    its better I explain.


    at work we have departments, who have department email addresses, ex. finance would be finance@...; or accounting would be accounting@...

    every employee has a personal email address which receives emails whenever their department's email is put in the email address line, but if someone puts my department's email address and also my personal one, I get the same email twice. I am also a part of multiple departments and can get the same email 3-4 times.


    Is there a rule or other way to only get one copy of that email and put the rest elsewhere automatically?


    You would really help me out if you know how to fix it.


    Thank you all in advance.
