Mail post

You're referring to the postal service!

Here are some common types of mail:

1. First-Class Mail: This is the most common type of mail, used for sending letters, postcards, and lightweight packages. It's typically delivered within 1-3 business days.
2. Priority Mail: This service is faster than First-Class Mail, with delivery times ranging from 1-3 business days. It's often used for sending packages that need to arrive quickly.
3. Priority Mail Express: This is the fastest mail service, with overnight delivery to most US addresses. It's often used for urgent or time-sensitive shipments.
4. Parcel Post: This service is used for sending larger packages, such as boxes or crates, that weigh more than 13 ounces.
5. Media Mail: This service is used for sending books, CDs, DVDs, and other media items. It's often cheaper than other mail services, but delivery times can take longer (up to 8 business days).
6. International Mail: This service is used for sending mail to addresses outside the United States. Delivery times can vary depending on the destination and type of mail.
