The usual (and useful) way to sign emails is with your name and some contact info (title, phone numbers). You could also add a saying like “My friend talked on, confident that he would soon find something to say”—Mason Cooley. (*Shrug*—we found that one on the web.)

Add any kind of signature you like!

Here’s how:

1. Click Options in the upper-right corner of your Mail page.
2. Under “Management”, click Signature.
3. Before you start typing, choose if you want to have your signature appear in plain text or in color and graphics. Above the text area, next to the word “Editor:”, click either Plain or Color and Graphics. With the toolbar that appears when you select color and graphics, you can choose which font you’d like to use and how you’d like to format and color it.
4. Now, add or change your signature by typing in the text area.
5. Check "Add signature to all outgoing messages" for your signature to appear on the emails you send. Anytime you’d rather not use the signature, return to this page and un-check “Add signature...” to turn it off.

Remember to click Save when you're done. This puts your new signature into effect.
