I am organizing a game and one of the requirements for this game is, me receiving "Email read notifications" when contestants open my PM.
I sent a trial question 3 days ago and for some strange reason out of 19 contestants I did not receive Email notifications from 4.
I sent one single PM to all of them and my "Email read notification" box is definitely checked. Even in my preferences, all three boxes relating PMs are checked.

All those contestants are in my buddy list.
Can someone look into this and fix it please?
I am planning to start this game in 3 days.😒
Cheers..
