Overheard at the airport

Sitting at the gate, waiting for boarding I overhear a conversation. A woman is texting on her blackberry and saying to her traveling partner, “You know that universal sign for ‘not’? He thinks that is why mail is ending up in the junk folder. And if we add it to our mail then it will get delivered.”
This is one of the strangest theories of email delivery I have heard in a long time.

Appropriating reputation

One of the thing savvy spammers are doing these days is appropriating the reputation of someone else. Reputation appropriate takes many forms. Some spammers hijack windows machines, turn them into bots and send spam through major ISP smarthosts. “Legitimate email marketers” buy service from mainstream ESPs to send their permission-challenged email that they cannot get delivered through their own IP space.
There are different strategies for companies to prevent bad groups from appropriating their  reputation. For the ESP, the prime defense against reputation appropriation is screening new customers and new lists.
When screening potential customers, there are three broad categories that customers fall into. One is the legit prospect that is exactly whom they represent to you, these are the easy guys. Another is the naive mailer, who really does not have any clue about email but wants to move into the digital age. This mailer is often extremely small, but knows nothing about email. The final category is the subversive prospect. This is the company who knows exactly what they are doing, and who is actively working to hide their practices from the ESP. They are attempting to subvert the process.
Over the coming weeks I will be talking more about screening new customers and how to distinguish the naive customer from the subversive one.

Reputation

Reputation is the buzzword in delivery these days. Everyone talks about building a good reputation and how to do it. Makes sense, the ISPs are always hammering on reputation and how critical reputation is. The more I talk with delivery folks on the ESP side of thing, the move I realize that there is a fundamental disconnect between what the ESPs mean when they say reputation and what the ISPs mean when they say reputation.
Many people handling delivery think that the bulk of reputation is wrapped up in complaint rates and bounce rates. I think they know the ISPs measure more than just complaints and bounces (spamtraps!) but really believe that most of developing a good reputation is all about keeping those complaints low.
This perspective may have been true in the past, but is becoming less true as time goes on. There are a lot of very smart people managing incoming mail at the ISPs and they are constantly looking for ways to better meet the desires of their customers. Lest we forget, their customers are not the senders, their customers are the end users. Their customers are not senders.
Part of meeting the needs of end users means actually giving them a way to provide feedback. AOL started the trend with the this-is-spam button, and other ISPs (ones that controlled the user interface at least) followed suit. For a very long time, reputation was dominated by complaint percentages, with modifiers for number of spamtrap addresses and number of non-existent users.
The problem is, these numbers were easy to game. Spammers could modify their metrics such that their email would end up in the inbox. In response, the ISPs started measuring things other than complaints, bounces and spamtraps. These other measurements are strong modifiers to complaints, such that mailers with what used to be acceptable complaint rates are seeing their mail end up bulked or even rejected.
Recently, AOL seems to have made some subtle modifications to their reputation scores. The result is mailers who have previously acceptable complaint rates are seeing delivery problems. When asked, AOL is only saying that it is a reputation issue. Lots of senders are trying to figure out what it is that is more important than complaints.
Tomorrow, I will talk about what I think AOL could be measuring.
