I am not getting this quite easily
If I have a DE, and I have multiple fields in it, and one is mapped as subcribey key ( ID let's say ), and id value is : 00848-454-555585545ds for one of the row, and there is an email field as well
Does that mean if I go to All subscribers and search by this id in the search by subscriber key tab, I am supposed to find the subscriber with the right email address ? right ?
bUT When I do that I find nothing
Example :
My DE properties and subscriber key
Two records :
If I look for this subscriber after a while, nothing is found :
Any detailed explanation on how this works exactly
Any help would be much appreciated
