LetterAgent
Mail physical letters by just asking your AI assistant.
Most no-mail days are completely normal: it is a Sunday or holiday, nothing was addressed to you, or your carrier is running behind schedule. Carriers are not required to stop at a mailbox when there is nothing to deliver, so an empty box usually means exactly that: nothing, not a problem.
| Reason | How to recognize it |
|---|---|
| Sunday or holiday | USPS does not deliver on Sundays or federal holidays; Canada Post does not deliver on weekends or statutory holidays |
| Nothing addressed to you | The most common reason on a normal weekday; carriers skip boxes with no mail |
| Carrier running late | Mail arrives at an unusual hour, or not until the evening route completes |
| Weather or route disruption | Storms, road closures, or a substitute carrier unfamiliar with the route |
| Blocked or inaccessible mailbox | Snow, a parked car, construction, or an aggressive dog keeps the carrier from reaching it |
| Holiday backlog ripple | The day after a holiday often runs light or late as the network catches up |
No, and this is the detail that explains most "where is my mail" anxiety. Delivery is address-driven, not schedule-driven: if the sorting equipment produced nothing for your address, the carrier passes your box without stopping. Neighbors getting mail while you get none is not evidence of a problem. It is evidence that they had mail and you did not. The system is working as designed.
The USPS offers Informed Delivery, a free service that emails you images of the letter mail scheduled to arrive that day. If the email shows pieces you never received, that is worth following up on. Canada Post has a similar delivery-notification setup for tracked items, though standard lettermail has no tracking and no preview, so a quiet day in Canada carries even less information. A second simple check: ask whether outgoing mail you left in the box was collected. If the flag is still up and your outgoing letters are still sitting there, the carrier genuinely has not come yet, or could not reach the box.
One quiet day is never the threshold. Start paying attention when the pattern breaks: you expected something specific (a check, a card, a bill you always get on the 3rd) and it does not arrive within a few days of its usual time, or Informed Delivery shows images of mail that never materializes. At that point, the sender-side checks come first: confirm the sender used the right address and actually mailed it.
If a specific expected piece is missing for more than a week in the US, file a Missing Mail search with USPS: the sooner the better, because undeliverable mail that cannot be returned is sent to the Mail Recovery Center, and items there are only kept for a limited time. In Canada, contact Canada Post once a reasonable window has passed; standard lettermail is untracked by design, so the investigation options are thinner, which is another reason to use tracked services for anything that matters.
