Can 2 day mail get here in 1

I see what you're getting at!

Unfortunately, no, 2-day mail cannot arrive in 1 day. The name "2-day mail" refers to the estimated delivery time frame, which is typically 2 business days from the date of mailing. This means that the mail will arrive within 2 days, not in 1 day.

The United States Postal Service (USPS) has specific delivery standards for its mail services, including 2-day mail. According to the USPS, 2-day mail is guaranteed to arrive within 2 business days for most domestic destinations. However, this is not a guarantee that it will arrive in 1 day.

If you need your mail to arrive in 1 day, you may want to consider using a faster shipping option, such as Priority Mail Express, which is guaranteed to arrive in 1 business day.
