Re: Delist/Unblock IP Address

Hi @mastscove


Thank you for reaching out! The Postmaster website is the best way to help you find out whether or not your IP address is still blacklisted. There was a glitch that caused messages to not get through to them, but that should be fixed by now. Try sending your message again. Just be aware that it will likely take a while for them to get back to you.


If you need assistance with anything else, just let us know!
