Many of our emails are bouncing due to blacklisting of Marketo's email address

250ok seems to have a nice automation for this tracking.

It looks like Marketo is a customer of 250ok. I wonder if this is a white labeled solution that Marketo packages with their deliverability offering.

it is.

Sounds like the same thing I have experienced also with the same error message from Symantec. Asking our top clients to whitelist Marketo ips is not a real solution.

Rodolfo Yiu​  we are in the same boat - frustrating!

We have been seeing great deliverability to our customers until this weekend. We have two dedicated IP addresses and for some reason this happened to us. We have been seeing 97%+ delivered to yesterday's 65%. It's ridiculous. Have you made any progress?

Hey Franklin, we'll take a look so go ahead and submit a ticket.

Hey Franklin - We had a similar issue when we first transitioned over to Marketo last year. We partnered with the Marketo Deliverability team and they were able to resolve all of our challenges. Tifaine Highly on the deliverability team is amazing. We now have quarterly check-ins just to confirm that there's nothing fishy going on.
