How to send a letter via snail mail, by going to the post office (the cheapest way)

Step 1: Write the letter and print it out.

Some tools you could use to write the letter using your computer are include Microsoft Word, Google Docs, Sublime Text, TextEdit, Evernote (or any notes app) and more. Once written on your computer, print the letter out on the paper you got. If you're using a pen, you can write on the paper directly.

Step 2: Write the mailing/recipient address and the return address on the envelope, on the closed side

The mailing address should go in the center of the closed side of the envelope. The return address should go in the top left. Postage information will go on the top right. The graphic below can help your orientation:

Step 3: Fold and stuff the letter in the envelope.

Step 4: Lick and close the envelope, then head to the post office to mail it. 

If you already have stamps that you're sure will work, you can affix the stamp to the top right of the closed side of the envelope, and drop it in a nearby mailbox. Otherwise, head over to the post office to weigh and buy postage. Once at the post office, you can head over to a postal worker for help, or you can use an automated kiosk.
