Mozilla is asking for feedback about Thunderbird and threatening a redesign. Thunderbird is the most feature-rich of the GUI mail clients, but as a result also has a lot of cruft. The goal of the survey is to learn what Thunderbird users think about the current design, what are the biggest drawbacks, what potential changes should there be, and so on. The claim is that the information will be considered before any actual changes are made to the program itself.

So if you rely on Thunderbird for any part of your work flow, speak up now before it ends up unusable trash like M$ Outlook or Apple Mail.

For now there is always SeaMonkey, which shares most of its mail code with Thunderbird. Unluckily SeaMonkey has the same problem as Thunderbird, how to proceed with Mozilla fucking up the back end. It's currently on the 52ESR backend channel and there are rumours it may stay there with some Linux dists backporting security fixes.
