Below is the format for a friendly letter. If emailing a friendly letter, you'd omit the heading (return address and date) of the letter and start with the salutation ( 3 )

Complimentary Close (Sincerely. ), 5
In the friendly letter format, your address, date, the complimentary close, signature, and printed name are all indented to the right half of the page (how far you indent in is up to you as long as the heading and complimentary close is lined up, use your own discretion and make sure it looks presentable). Also the first line of each paragraph is indented.
1 Your Address
All that is needed is your street address on the first line and the city, state and zip on the second line. (Not needed if the letter is printed on paper with a letterhead already on it.)
2 Date
Put the date on which the letter was written in the format Month Day Year e.g. August 30, 2003. Skip a line between the date and the salutation.
3 Salutation
Usually starts out with Dear so and so, or Hi so and so. Note: There is a comma after the end of the salutation (you can use an exclamation point also if there is a need for some emphasis).
4 Body
The body is where you write the content of the letter; the paragraphs should be single spaced with a skipped line between each paragraph. Skip 2 lines between the end of the body and the complimentary close.
5 Complimentary Close
Let's the reader know that you are finished with your letter; usually ends with Sincerely, Sincerely yours, Thank you, and so on. Note that there is a comma after the end of the complimentary close and only the first word in the complimentary close is capitalized.
6 Signature
Your signature will go in this section, usually signed in black or blue ink with a pen. Skip a line after your signature and the P.S.
7 P.S.
If you want to add anything additional to the letter you write a P.S. (post script) and the message after that. You can also add a P.P.S after that and a P.P.P.S. after that and so on.
