User blog comment:Kirkburn/Technical Update: April 27, 2015/@comment-452-20150427203902/@comment-5275700-20150429230417

The current plain text emails (as of the April 28 release) are auto-generated based on the main/HTML version. Our goal is to avoid having to manually set up (or edit) a plain text version of an email each time we create (or update) an email message in the new style.

We'll explore options for making the auto-generated plain text emails include the links, but unfortunately it's not as easy as one might think. There may be other options as well. At this time I don't have an estimate on when a further update will occur.
