Working with email signatures

A signature consists of one or more lines of text (or even a picture) that will be added at the end of an email that you send. It can contain contact information or other things.

The term "signature" is also differently used in terms of encryption.

Per long-standing convention, signatures always start with two dashes and a space in a separate line. This allows many email clients to automatically strip signatures from quotes when replying.
