What can you mail in a letter envelope

In the United States, the United States Postal Service (USPS) allows you to mail a variety of items in a standard letter envelope, which is typically 3.5 inches high, 6.125 inches long, and 0.007 inches thick. Here are some examples of items that can be mailed in a letter envelope:

  1. Letters: The most obvious item, of course! You can mail handwritten or typed letters to individuals or businesses.
  2. Postcards: While postcards are designed to be mailed separately, you can also mail them in a letter envelope if you want to add a small note or gift.
  3. Photographs: You can mail individual photographs or a small collection of photos in a letter envelope.
  4. Small gifts: Consider mailing small gifts like keychains, magnets, or other small trinkets.
  5. Business cards: You can mail business cards to clients, colleagues, or potential customers.
  6. Invitations: Invite friends, family, or colleagues to events like parties, weddings, or conferences.
  7. Notices: Mail notices, such as eviction notices, utility bills, or other official documents.
  8. Small packages: If you need to send a small package, like a book or a small item, you can mail it in a letter envelope if it weighs less than 3.5 ounces.
  9. Gift cards: Mail gift cards to friends, family, or colleagues as a thoughtful gesture.
  10. Personal items: You can also mail personal items like a handwritten note, a small piece of artwork, or a sentimental keepsake.

Remember to always check with the USPS for specific guidelines on mailing items, including size and weight restrictions, as well as any special requirements for certain types of mail.
