How Spamfilters Work

AllSpammedUp has a post describing the primary techniques anti-spam filters use to identify mail as spam or not spam.

Without that base knowledge, it’s difficult to troubleshoot problems and resolve issues. […]

Confirmed opt-in

I spent the morning in multiple venues correcting mis-understandings of confirmed opt-in. The misunderstandings weren’t so much that people didn’t understand how COI works, but more they didn’t understand all the implications. In one venue, the conversation centered around how small a portion of deliverability the initial subscription process affects. Sure, sending unwanted, unexpected email […]

His article is quite open and points out that some of the things Penton does are not good. A couple answers weren’t pretty. For one thing, I found out we don’t have a permission box asking […]

Poor delivery is not always about spam

There are days I think we have trained people too well to believe every delivery problem is a misplaced spam block. We also have people trained to expect near 100% immediate delivery from send to inbox. The problem is, email isn’t 100% reliable. It’s close. Very close. But sometimes mail just fails. It’s not because […]

Buying lists and other stupid marketing tricks

Back in November, I commented on Zoominfo and that they were selling senders very bad lists. At that time, Zoominfo did not have my current information. They have since rectified that problem and are now selling my information to people. This morning, I received an email that said: I wanted to follow up on a […]

Subscribers notice what marketers do

Stephanie Miller from RP blogs at EEC about a UK consumer survey with the take home message: “consumers notice what email marketers do. When we send something interesting and relevant at a good pace, they are happy to stay active with our programs. When we don’t… well, then we’ve lost them, perhaps for good.”

  • Lost in the mists of time

    Over on the Farsight Security blog Joe St. Sauver talks about some of the early days of online abuse, on usenet. Laura and I were on the periphery of early usenet abuse, mostly as users, but Usenet (and IRC) around then were the places we both started with email abuse.No Comments

  • Ongoing Yahoo delays

    I've been hearing from folks over the last few days that they're seeing an uptick in deferrals from Yahoo! The deferrals are not uniform. ESPs report they're seeing some, but not all, customers affected. Other ESPs aren't seeing any changes. It's not just you. But it would be very worthwhile to dig into engagement and other stats. It's possible this is a new normal at Yahoo! and they're tightening filters to catch mail that doesn't fit their standards but was previously difficult to filter.No Comments
