What happens to mail that is not forwarded

When mail is not forwarded, it typically follows one of the following paths:

1. Returned to sender: If the mail is undeliverable because the recipient has moved and not updated their address, the mail carrier will return it to the sender. This is usually done after a certain period, typically 30-60 days.
2. Abandoned: If the mail is not returned to the sender, it may be considered abandoned and disposed of by the postal service. This can happen if the sender is unknown or if the mail is deemed to be of no value.
3. Donated or recycled: Some postal services, like the United States Postal Service (USPS), have programs to donate or recycle undeliverable mail. For example, the USPS has a program called "Operation Santa" that donates unclaimed mail to charities.
4. Sold at auction: In some cases, undeliverable mail may be sold at auction to collectors or enthusiasts. This is more common for rare or valuable items, such as stamps or coins.
5. Destroyed: In some cases, undeliverable mail may be destroyed, especially if it contains sensitive or confidential information.

It's worth noting that the specific fate of undeliverable mail can vary depending on the country, postal service, and local regulations.
