Does anybody know the specific safe-sender/whitelisting instructions for ATT.net, Bellsouth and SBCglobal? We're sending a message to these specific ISPs and want to make sure they add our sender address as a safe sender, but our audience tends to be older, so we want to be able to provide specific instructions on how to do so. These were the least complicated ones I found, but just figured I'd post to see if anyone had any other instructions. Thanks!
Do you mean the lead's specific viewer? You'll have to do a search on the vendor's site or just create an account there and look.
Usually you just add someone to the Contact/Address Book at the individual level.
