Thanks for pointing me to that thread. I started one because I couldn't find an existing thread. However, I prefer to keep commenting here, as that thread seems to have devolved into a criticism of the travel agency, which Í'm honestly not interested in continuing.
According to First Class Flyer, this is a new category offered by Delta called "EasyUp" and not something limited to the travel agency. See the following "press release" about the newsletter:

It also seems to say that American is following Delta, but nothing is available on AA.com, nor could I find anything official on Delta.com.
I'm going to try to get the newsletter via a trial subscription and will post further details if successful.
