The Insider’s Guide to Thunderbird Signature

In this tutorial, we will show you the quick and easy way of adding the HTML email signature to outgoing messages from Mozilla Thunderbird. If you using the Thunderbird application you have probably noticed that adding the email signature is not as easy as it is in Outlook!
There are few steps you need to follow to create a simple signature. Plus you need to know a bit of coding. Whether you’re company or individual, these thing comes handy.

The Text editor

First, open the text editor, we use Notepad ++ if you don’t have this application you can use your builtin editor like Notepad.

How and Where

Second, paste the code below and change the highlighted (bold + italic) fields to your details.

<meta http-equiv="content-type" content="text/html; charset=utf-8">
<title>Email Signature</title>
<body bgcolor="#FFFFFF" text="#000000">
<div class="moz-signature">
<pre class="moz-signature" cols="72">--
mob: Your Tel. Number<br><br>
<a href="" moz-do-not-send="false"></a><br><br>
<img alt="ovipic" src="http://www.yourwebsite/images/logo.png" height="38" width="114"><br>

What After Adding Code

Third, replace the logo hyperlink. Please make sure the logo is available online! You have to paste there the actual logo path. If you don’t know how to find it, the easiest way is to browse in google for images. Once displayed, please left click image an choose “Open image in new tab” – this is the menu descriptions for the Chrome Browser some browsers will not have this option! Once in the new browser window (with just an image displayed) please copy the path/ URL to this picture/logo. and paste in place of “yourwebsite/images/logo.png” – please see code above. Now, when all the contact number email and logo details have been amended, please save the entire file as a signature. Please remember that the file should have the .html extension. Also, please make sure you save locally on your machine and remember its location.

Last Step

Step Four, open Thunderbird and navigate to menu hamburger in the top right corner > hover over the “Options” > choose “Account Settings”. A new window will open with your accounts on the left, please select the account (name with little envelope icon). Once clicked you will see “Attach signature from a file instead”. Please check this option and choose previously saved signature.html. Now when you’ll create a new email your signature will appear below.
