Signatures on emails relieve the sender from writing the same information over and over again. Signatures allow users to include the information to be sent with every email, including name, contact details or a quote.Colored signatures are particularly helpful when the mailbox is configured to send automated replies or messages. It is possible to add a signature under Thunderbird mail which is sent automatically. The information that forms the signature has to be put into a file and saved in HTML format so that it can be viewed properly in an internet browser.
