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.

  • 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
