Please check your spam/junk folder.
Then, if you're using a @comcast.com email, note that for some reason beyond our control or comprehension our emails are frequently being silently blocked to this domain (e.g., the recipient has no information about the blocking or control over it, and we as the sender rarely get any information either). Our repeated attempts to unblock our mail server at Comcast seem to have a very short-term effect before the blocking resumes, and we don't see any way to make this better. We kindly ask you to use an email address from some other domain.
