i want to ask something about email experience manager, im using version 3.1.
my case is if i have many product(i want to blast email campaign about that products to my subscribers), for example product A, product B, and product C.
I send that email with content product A with the csv that has 100 recipients, and then 5 recepients want to unsubscribe that product and clicked unsubscriber link.
what i want to ask is :
if i send product B, is it the unsubscribe(5 recipients) still getting email campaign about product B and will not getting email campaign about product A ?
do i have to set different manager root so the recepient on product A didnt effect the recepients on product B(for example it has the same csv recipents file)
the difference between unsubscribe and unsubscribe from all( i did read the sitecore documentation but im still kinda confused, im so glad if you can give me example case)
thank you for your help, im new to sitecore and i kinda lost and the moment.
