Derek Harding has a pair of articles on ClickZ about Gmail giving their users information about why a particular email message was filtered.
What Gmail Teaches Us about Spam Filtering
Gmail Filtering: The Spam Disposition
Both articles are worth a read. They talk about what we know about Gmail and what we can infer from the data they provide to senders.
I found this article over on Hubspot, and I think it covers a lot of why people hate email marketing quite well.
Congratulations go out to Matt Blumberg for being named one of the top entrepreneurs for 2012 by Crain’s New York Business!
A reader has been talking with AOL about the mtain* responses that people were receiving. AOL has said both responses mentioning mtain-*.r1000.mx.aol.com are actually DNY:T1 bounces that are being presented incorrectly. Both responses should be treated the same as 421 DYN:T1.
A number of senders are reporting that they’re getting unusual responses from AOL servers. The responses include: 421 mtain-dk10.r1000.mx.aol.com Service unavailable – try again later 554 mtain-dk03.r1000.mx.aol.com ESMTP not accepting connections mtain-dk* are assigned reserved IP addresses. It looks like something broke inside AOL again, and lots of places are having trouble...
Return Path have an interesting post up about content filtering. I like the model of 3 different kinds of filters, in fact it’s one I’ve been using with clients for over 18 months. Spamfiltering isn’t really about one number or one filter result, it’s a complex interaction of lots of different heuristics designed to answer the question: do recipients want this kind of mail?
I’m still hearing reports that AOL is still having problems accepting mail. I’ve also heard they’re still working on it. There is no information on when a fix may be finished.
The Five-Ten website has a notice that they have retired the blacklist. Five-Ten wasn’t the greatest list for blocking mail, they aggressively listed senders and there were a number of false positives against a standard mail stream. But it was useful as a touchpoint. If I had a client that wasn’t listed on Five-Ten that told me something about their normal practices.
77% of those surveyed preferred email for permission-based promotional messages, soundly beating the next most popular, direct mail, at 9%. Email, still anything but dead.
This, and lots of other interesting things, in ExactTarget’s 2012 Channel Preference Survey.
The Communications Security, Reliability and Interoperability Council (CSRIC) published a Anti-botnet code of conduct for ISPs. This is a purely voluntary code for U.S. ISPs that want to mitigate the botnet threat to follow. You can download a full copy of the final report from the MAAWG website. The FCC has published a fact sheet about the report on their own website.
