In the AB test, if one of them has no action at all, Subsequent all judgment will be wrong.
Ex.)
Dlivery A: One person does not open
Dlivery B: One person opens
After that , all winner is "Dlivery A".
Also, you cannot control the same rate.
"Dlivery A" is always the winner...
It is a number of targets is small, It may not be realistic.
But in the unlikely event that it happens, The delivery record of campaign dushboard must be deleted.
Is there any countermeasure?
Thank you.
