If your email stopped arriving, you can now turn it back on properly
When an email we send you bounces, we switch off your digests. That is deliberate: continuing to mail an address that is refusing our messages helps nobody, and it can get our mail blocked for everyone else. But until now it happened quietly, and there was no way back.
Your notification settings page now tells you when this has happened to you, in plain language, and gives you a button to put your settings back.
The part that changed today is that the button now works all the way through. Restoring used to hand you your choices back while our email service went on refusing to send to your address, because it keeps its own separate record of the delivery problem. You would have turned everything on and still received nothing. Restoring now clears both sides, so messages start arriving again.
If your address still cannot receive mail, the next message will fail and we will switch these off again — and you can come back and restore them once more. Nothing is lost either way.
Password resets and address verification were never affected by any of this. Locking you out of your own account over a full mailbox would be the wrong trade.
