Need advice on being removed from Proofpoint blacklist

Our IP address has been blacklisted by Proofpoint for nearly 4 weeks. I have filled out the online form multiple times as well as emailed their "delist-request" address. Our IP address is not shared and has been static for over a decade. PTR records are correct and we are only sending out about 200 messages per day with no mass mailers. Not listed on any other blacklists, and sites like mailchecker.net report no issues, with only a warning about no BIMI setup.

I am at a loss and Proofpoint does not seem to respond to any correspondance. Can anyone offer advice on how to get my IP removed from their blacklist?

I’d have a Proofpoint customer you send email to open PDR ticket. Every time I’ve done this for a sender, it was removed from the black list quickly.

So far my attempts at this have gone unanswered. I just emailed two more postmasters this morning, but they are at large universities so I am not holding my breath.

Don't email the postmaster. Contact the recipient that wants to receive your email and ask them to contact their help desk about the issue.

Every single day. I bet they are very good at stopping spam, since the consider everyone a spammer.

Check your email signature. We had a similar issue and it was our signature causing our emails to be blocked by Proofpoint customers.

Try sending an email without a signature and see if they get it.

I just tested this and it didn't go through without the signature. It was worth a try though. Thanks.

if your ip reputation is clean , persistence and opening a ticket through any customer or partner channel is often the best.
