Hey, Some of my domains got DBL and some IPs got Barracuda, but i de-listed them immediately. My question is can I still use those domains and IPs in the future mailing?
A friend of mine told me with DBL, you still can reuse them, but on the other hand, my mentor told me not too lol. So I dont know about this one, but with barracuda, you shouldn't have any problem reuse the IP.
