How to add signatures in Mozilla Thunderbird?

"Signatures" are blocks of text that are automatically appended to every message that you send (including both new messages and replies to incoming messages). They are generally used to provide additional contact information, legal terms or some other boilerplate information that is relevant to every email. This article explains how to configure and use signatures in Thunderbird.

About signatures

A simple text email signature might say something like:

John Doe

Minion

The Big Example Organization


Simple text Signatures are created in Thunderbird's Account Settings interface. Click on the menu button  (or on 'Menu Bar' use Tools) > Account Settings, and then, in the left panel, select the account for which you want to create a signature.

If you have multiple email accounts, you must configure signatures separately for each account.

Plain-text signatures

To configure a plain-text signature, enter the text you want to append to each outgoing message in the Signature text field. Plain text signatures work with messages formatted both in HTML and in text.

HTML signatures

To use HTML formatting in your signature, check Use HTML and format the Signature text with the desired HTML mark-up. If you send messages in text (rather than HTML) format, text characters will be substituted for the HTML markup.
