In email, what is a signature?
A signature is a brief text message about yourself that you can have your mail client add to your email messages. A signature usually consists of your full name, a preferred email address, brief information about your school, company, site, or occupation, and perhaps a witty remark or quote that you want to share with the world.
For help setting up your mail client to add a signature to your messages, see:
- In Microsoft Outlook for Windows, how do I create and use a signature?
- In Outlook Web Access, how do I add or edit a signature?
- With a BlackBerry, how do I change my signature?
- In Mozilla Thunderbird, how do I create a signature?
If your mail program is not listed above, consult the help files for your program.
It's usually polite to keep your signature as brief as possible. If you're creating a signature on a web forum, be aware that some forums limit the length of signature files. Avoid large ASCII text pictures, empty lines, and lengthy quotations when composing your signature file.
