What do I do if my mail has stopped being delivered?
Okay, that's good to know. Is there anything else I should do to make sure my mail is protected?
One thing you can do is to sign up for Informed Delivery, which is a free service that allows you to see images of your mail before it's delivered. This can help you identify if any mail is missing or if you've received something that you weren't expecting.
