Where should I write my email address and phone number in a letter?

If you take this example of how to set out a letter: http://www.write-for-business.com/images... where should one write one's email address and phone number?
This is personal letter, therefore there will be no company letterhead under which to include it.

Under your address. Phone then email.

I've always included them at the bottom, in a footer (assuming it is a typed letter). If it is hand-written, I put them in the body of the letter.

I usually include mine at the end, after I've signed it.

I would think after the salutation, under your signed name

in the bottom, after the " sincerely, signed, so and so, then the e-mail, and phone #.

respect the business ethics,try to use another computer, even if you own the business.

if it's a personal letter you can put it anywhere you choose.

I just put mine under my name and address. So all details together.

Then you should put it above the letter (where "Cust. Service Dept." is on your example.

Your example is a business leter. For a personal letter, though, it's acceptable to all be on the same side. The reason it can go there is because, in a personal letter, you don't need to write the persons [recievers] name, address, and number.

Dear Sir/ Madam

I'd write them at the bottom, under the signature.
