I'm trying to send AB Testing in nun key DB with duplicate emails adress.

The AB testing process working today is first divide the query to A, B and remainder and then remove duplicate.

It's mean that if I have duplicate email contacts it possible that the same email adress will get A, B and remaind emails...

My idea is to change the order of the process - First remove duplicate email adress from the query and then divide it to A, B and Remainder. If it work like this - each email adress will get one newsletter only.
