Sometimes, for reasons beyond the recipient’s control, things go wrong. Mailbox gets attacked and goes over quota. DNS servers go down (should never happen, but) BGP hijack.
All sorts of things are possible. But if you’re getting a bounce, and the server or account is down for more than a day, and you’re trying to re-engage, then remove ‘em. Hard and fast rules are good in theory, lousy in practice, just like practical rules can be horrible in theory. Somewhere in the middle is the truth. But don’t ignore signals.

Stop mailing. - Clicked on opt-in link or "yes" button. Continue mailing. - Did nothing. Send one reminder mail asking them again to opt-in in 7-10 days. After that, let them go. Stop mailing them. +1, and can we go even further? Confirmed double opt-in subscribers are MUCH more valuable that single opt-in, you might even consider keeping all confirmed double opt-in completely separate from other types of mailings, so that that part of your service always has the highest reputation. But you still need to pay attention to engagement with your confirmed subscribers. And reconfirming folks who confirmed 5 years ago but have not clicked on any link or opened anything or logged into your website in the previous 3 years is a good idea, no matter that they confirmed years ago. laura -- Having an Email Crisis?
