A signature may refer to any of the following:
1. A signature or signature block is data used for identification purposes found in e-mail messages. A signature may contain the individual's name or alias, job description, company, e-mail address, position, phone number, URL (uniform resource locator), quote, or joke. Below is an example of the Computer Hope signature sent with all our e-mails.
-- Computer Hope Free computer help since 1998 https://www.computerhope.com
The picture below is an example of a window that appears when composing a new e-mail message. In our example, the signature is automatically inserted any time a new e-mail message is being composed.
E-mail signature etiquette
- Keep the signature as small and simple as possible. We suggest no more than four lines.
- Your signature doesn't need to be a complete bio of yourself. If you have five different phone numbers, you shouldn't post all five of them in your signature. Often a cell phone number is enough.
- Have a divider or empty lines between the signature and the main message.
- Don't advertise more than your web page. Everyone gets bombarded enough by e-mail solicitation.
2. Signatures are also often found on online communities and forums as a way for a user to identify themselves, something they enjoy, etc. Great examples of online signatures are on the Computer Hope forum.
