Meaningless metrics

I’ve been having some conversations with fellow delivery folks about metrics and delivery and bad practices. Sometimes, a sender will have what appear to be good metrics, but really aren’t getting them through any good practices. They’re managing to avoid the clear indicators of bad practices (complaints, SBL listings, blocks, etc), but only because the […]

Reporting email disposition

Most regular readers know I think open and click through rates are actually proxy measurements. That is they measure things that correlate with reading and interacting with an email and can be used to estimate how much an email is wanted by the recipients. The holy grail is, of course, having ISPs report back exact […]

The underlying need for metrics is to evaluate how effective a particular marketing program is. Picking metrics involves understanding what the goal is for a particular program.

When an open is not a sign of interest

A lot of people, including myself, are using opens as one of the measures of engagement. This, as a general rule, is not a bad measure. However, there are people who will open email not because they’re interested in it, but because they know it is spam. Take, for instance, the email address I acquired […]

Failed delivery of permission based email

A few weeks ago, ReturnPath published a study showing that 20% of permission based email was blocked. I previously discussed the definition of permission based email and that not all the mail described as permission based is actually sent with the permission of the recipient. However, I only consider this a small fraction of the […]

  • AOL problems

    Lots of people are reporting ongoing (RTR:GE) messages from AOL today.  This indicates the AOL mail servers are having problems and can't accept mail. This has nothing to do with spam, filtering or malicious email. This is simply their servers aren't functioning as well as they should be and so AOL can't accept all the mail thrown at them. These types of blocks resolve themselves. 1 Comment


  • Fixing discussion lists to work with new Yahoo policy

    Al has some really good advice on how to fix discussion lists to work with the new Yahoo policy. One thing I would add is the suggestion to actually check dmarc records before assuming policy. This will not only mean you're not having to rewrite things that don't need to be rewritten, but it will also mean you won't be caught flat footed if (when?) other free mail providers start publishing p=reject.No Comments
