By mail

You're looking for information on sending something "by mail". Here are some common ways to send items via mail:

1. First-Class Mail: This is the most common type of mail, used for sending letters, postcards, and lightweight packages. It's usually the most affordable option.
2. Priority Mail: This service is faster than First-Class Mail, with delivery times ranging from 1-3 business days. It's a good option for sending important documents or 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 a good option for sending time-sensitive items, such as packages that need to arrive the next day.
4. Parcel Post: This service is used for sending larger, heavier packages. It's usually less expensive than Priority Mail, but delivery times can take longer (3-9 business days).
5. International Mail: If you need to send something to another country, you'll use international mail services like Global Priority Mail or First-Class Package International Service.

When sending something by mail, make sure to:

• Use the correct postage
• Address the package correctly
• Use a sturdy envelope or box
• Insure the package for its value (optional)
• Keep a record of the tracking number
