The past several times I sent bulk emails I get some bounced emails.
When I check the recipient's list to remove these bounced addresses, they were already unsubscribed (with a red X icon).
Today about 12 emails that were unsubscribed go mailed to and bounced back.
How can I make sure the unsubscribed emails do not get sent?
Answer: I believe you are using several lists or you are sending messages using previously saved documents. In both cases, unsubscribing recipients may not be enough.
You should seriously consider using the MaxBulk Mailer global blacklist. In fact, the Global Blacklist prevents you from sending messages to given addresses whichever the list you have selected. In other words, you just need to add the address once to the blacklist to get it automatically blocked everywhere else! Furthermore, you can even block a whole domain or a name independently from its domain!
