Yes.

I've just deployed the changes that add the page with the list of the
tested repositories as well as a link to it from the "main page" (look
above the table with instances). For Android, we indeed don't test
many trees:

https://syzkaller.appspot.com/android-5-10/repos

For Linux upstream, there are more trees:

https://syzkaller.appspot.com/upstream/repos

Now such email messages will include the kernel name and some of the
tested repositories (with the link to the full list page). E.g.
https://github.com/google/syzkaller/blob/4067838e6b16173af08e062ce434ecfc46d45bda/dashboard/app/notifications_test.go#L106
