AOL Postmaster page changes

AOL has disabled the IP reputation check and the rDNS lookup on their postmaster pages. Given AOL isn’t handling the first mail hop any longer, this makes perfect sense. They simply don’t have the kind of data they did when they were handling mail directly from the sender MTA. There’s no information, yet, on whether […]

How long does it take to change reputation at Gmail?

Today I was chatting with a potential client who is in the middle of a frustrating warmup at Gmail. They’re doing absolutely the right things, it’s just taking longer than anyone wants. That’s kinda how it is with Gmail, while their algorithm can adapt quickly to changes. Sometimes, like when you’re warming up or trying […]

Spam isn’t going away

I got a piece of B2B spam last week that showed in several different ways why spam isn’t going away any time soon. Systemic problems dealing with abuse at scale at Google.

Yahoo fixed

The Yahoo bounce problem has been resolved. There were erroneous ‘554: this user does not have a yahoo.com account’ between March 14 and March 16. If you attempted to send mail and received this bounce during that time you can reactivate the address in your database. Most ESPs should be able to help you with […]

Happy International Women’s Day

It’s International Women’s Day, and I thought I’d take a moment to mention some of the many, many women who have inspired me and helped me along the way. Some of them work in deliverability and compliance. Others are business colleagues. Still others are cheerleaders and inspiration. All of them make the world a better […]

What does good IP Reputation get you?

Today I was discussing some mailing list posts with an ESP colleague. He was telling me some interesting numbers he’d collected from different IP pools they maintain. He was testing routing mail through IPs based on subscription process and routing based on engagement metrics. The data showed that inboxing rates were similar across the test […]
