Blogging will be light through Jan 4th as I’m actually taking some time to visit family, relax and […]

Typical ESPs

Yesterday, I gave examples of good ESPs and the benefits that their customers receive from their high standards and standards enforcement. Today I’ll be talking about typical ESPs and the things they say and do. A few caveats before I get started. Most of these quotes are composite quotes. I am not quoting one particular […]

What makes a good ESP?

There are a number of things that make a responsible ESP, including setting and enforcing standards higher than those set by the ISPs. One of the responsible ESPs is Mailchimp. (Full disclaimer, I do consult for Mailchimp.) This ESP focuses on businesses with small to medium sized lists. They screen new customers for source of […]

The good, the typical and the ugly

In the theme of the ongoing discussions about ESPs and their role in the email ecosystem, I thought I’d present some examples of how different ESPs work. The good ESPs are those that set and enforce higher standards than the ISPs. They invest money and time in both proactive and reactive policy enforcement. On Monday […]

Cultural Bias

Guest post by Chris Wheeler After reading Laura’s and Steve’s posts on the gap between the “senders” and “receivers” (both excellent reads I recommend if you haven’t already done so), it really made me think about why I do what I do and why I think (hopefully not being too narcissistic here) that I’m reasonably […]

  • 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.
