I spoke too soon. I get an email for https://gitlab.common-lisp.net/cmucl/cmucl/-/merge_requests/93#note_11478 but I responded to that comment in https://gitlab.common-lisp.net/cmucl/cmucl/-/merge_requests/93#note_11479 and didn't receive an email.
Bummer.

Are you sure it's supposed to send you emails for your own comments?
