Yes, the post office processes mail on Sunday. Mail is always moving. But, not on national hoildays, though. However, the mail does not move as quickly on Saturday/Sunday. For example, a letter delivered to a Saturday 5PM pickup box will not make it to a destination on Monday, that would normally be delivered to the next day, if it were mailed from that same box at the prior day 10AM pickup.
In the United States, currently, the Post Office delivers mail Monday through Saturday. USPS (United States Postal Service) does not mail on Sundays or on Major Federal holidays.
The post office does deliver mail on Valentine's Day as long as the date does not fall on a holiday or Sunday.
US mail comes everyday but Sunday. Time depends on the delivery schedule from you local post office. The USPS is trying hard to eliminate Saturday deliveries as a cost savings measure as the Post Office is losing huge amounts of money.

No, all mail is Monday through Saturday. The post office is a federal government office.
You take your mail/package to the nearest post office and then you can mail it.Common Sense.
post office = royal mailmail = post or letters mailbox = letterbox to mail a letter = to post a letter
you put a stamp on the letter, stick it in your mail box, or run up to the nearest post office, or stick it in the mail box outside the post office.
The US post office is never open on Sunday.
