Yesterday, I got a DKIM-signed message from Super User with the subject "Check out the Super User Weekly Newsletter". It has been eons since I used the account and, yep, I couldn't even recover the password for the account by providing the email address that the message was sent to.

The URLs in the email (e.g. one starts with https://stackexchange.com/email/unsubscribe-newsletter/) are all 404s. But the content looks legitimate.

Is this the result of some botched internal testing?

    The link(s) are 404s? This was not raised on the other question.

    No-repro on the 404s. The ones I see have a code tacked on the end of the stub listed above, and go to the right place. Are you using the whole URL provided on the email, Mark? Aug 18, 2011 at 17:17
  • @M. Tibbits: note that Mark said that the URL starts with the stub listed above. The link above returns a 404 for me, but the links I see in my email are longer, and go to the right place. Aug 18, 2011 at 17:49
  • Oh sure thing. Sorry 'bout that -- again, I didn't get the email / couldn't confirm. Perhaps it was a word wrapping issue and he truncated the link?

  • @M. Tibbits I couldn't log in and I couldn't recover my password even when I gave it the email that the newsletter was sent to -- it said there was no such account. Maybe the links only worked when you could log in with that account? Aug 18, 2011 at 20:02
  • @mark odd, when I go to superuser.com/users/account-recovery and enter the email address on file at superuser.com/users/11816/hexmode I do indeed get "email sent" Aug 19, 2011 at 0:30
  • @jeff atwood, I think the problem came because it wasn't clear that the account I created was particular to superuser. I suspect the fact that I only used SuperUser a once a year or so ago led, in part, to the problem. The emails I got didn't link to superuser to subscribe/unsubscribe -- they went to stackexchange -- so I didn't see the lost password link for superuser, I saw one for stackexchange and, not being a frequent user, didn't realize that they were different. After all, I thought, if I can use stackexchange OpenID credentials to log in, then maybe that is where my log in is. Aug 19, 2011 at 1:18

A small number of people received broken unsubscribe links at the bottom of the one-time newsletter promotion email. Unfortunately, I haven't been able to track down the cause of this bug yet.

In the meantime:

  • Mark, I've manually unsubscribed you from this list.
  • If anyone else has been unable to unsubscribe, please email [email protected], and we'll unsubscribe you immediately.

Sorry for the inconvenience.
