Over the last week or so a number of people have mentioned problems with delivery to Yahoo. It seems that some emails are being erroneously rejected.

Another perspective on the Politico article

Yesterday, I talked about the delivery advice that could be gleaned from the Politico article The best e-mail lists in politics. While there are some good practices and attitudes expressed in the article, there are problems with how some of the political lists are being handled. For instance, Ken Magill signed up for any number […]

Politico published an article Sunday looking at the best e-mail lists in politics. Their criteria for choosing the winner focused on list size and recipient engagement, measured by amount of money raised and recipient response to issues.

ReturnPath customers?

Someone posted the following question about ReturnPath in the comments: Does anyone have any reports or links as to whether Return Path are worth the thousands p.a that they charge?

Even dumber is sending a followup a week later with a notice at the top. Did you receive the e-mail which I sent to you recently (copied here-below)? Please confirm since […]

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
