Mail on sunday usa

The Mail on Sunday is a British newspaper, not a US-based publication. However, I assume you're asking about the postal services in the United States on Sundays.

In the United States, the United States Postal Service (USPS) typically does not deliver mail on Sundays, except for certain circumstances. Here are some exceptions:

1. Priority Mail Express: This service is available 365 days a year, including Sundays.
2. Priority Mail: While regular Priority Mail is not delivered on Sundays, some Priority Mail packages may be delivered on Sundays in certain areas, especially in urban areas.
3. Parcel Select: This service is used for larger packages and may be delivered on Sundays in some areas.
4. Special circumstances: In some cases, USPS may deliver mail on Sundays in response to natural disasters, emergencies, or other extraordinary circumstances.

It's worth noting that private courier services, such as UPS and FedEx, may deliver packages on Sundays, but this is not a standard practice for USPS.

If you're looking for a specific delivery date or have a question about USPS services, I recommend contacting your local post office or visiting the USPS website for more information.
