The Email Wars

Over on the Yahoo Mail Blog they stated they have been doing work on Yahoo Mail classic, and of course, anytime they do work, there are bugs.

The postmaster and development teams at Yahoo have been using the blog to communicate changes, and actively read comments from users. If you are experiencing problems, it is a good place to post or read comments from other users to see if they are already aware of the issues.

Comments from the WEB on this:

Someone was asking about problems with Yahoo yesterday. I use Yahoo Classic for my personal emails and I noticed yesterday and today that it’s making emails that I haven’t opened as read. If I mark those as unread, it then marks other unread emails as read. So perhaps there’s not a deliverability issue but one with open and click rates because subscribers are not reading messages because Yahoo is telling them that they’ve already looked at the emails. Anyone else seeing this?

I’m seeing similar problems in the new version of Yahoo Mail. Over the past week, in my personal account:

Previously read & deleted emails have returned to my inbox as unread
The inbox has failed to load & generated JavaScript errors
Individual messages have been failing to load, generating internal Yahoo error messages to try again

It seems as if they may be doing some behind-the-scenes work that’s negatively impacting the user experience–and, in some cases, making select messages unreadable for a period of time.
