Thunderbird Identities

Thunderbird offers identities:

  • This means you can have different sender information or signatures at the bottom of your mails per used e-mail address.

Go to "Account Settings" from the menu, select an account from the left, click button "Manage Identities..." and you'll find your way.

But... There is more:

  • You can use multiple identities - so also multiple signatures - for the same e-mail address. Actually, this is obvious but often overseen. Not further explained here.
  • Dealing with images in signatures can be hard and need some clarification.

It used to be easy, just create a link to your image somewhere online and it was included in the signature. But loading content for the receiver is considered unwanted.

So we have to include our signature logo in-line. That is where BASE64 comes in handy. An example is probably the easiest way to go. This is what is in my signature when I mail for NedCAD:

<p style="font-family:sans-serif;font-size:1.0em">
Best regards,<br>
Your Name<br></p>
<a href="http://yoursite.ext">
<img src="data:image/png;base64,
alt="" height="38" width="131" border="0"></a><br>
<p style="color:#2f5496;font-family:sans-serif;font-size:0.8em">
Telephone and more...</p>

Before we get to the base64 part - the fancy character part - first HTML.

  • <br> are the breaks.

  • <a href="http://yoursite.ext"> is the link to the site (your site). However, notice that the closing tag </a> is after the base64 block, your logo is clickable.

  • Feel free to modify the HTML code further.

About the base64 block...

  • Please optimize your logo.
    • With much colours and gradients use JPG.
    • Otherwise save as PNG with the option to reduce the number of used colours.
    • Check for smallest file size.
  • If you're happy with it, mail it to yourself. When you receive the mail with your logo...
    • Select it and press Ctrl-u.
    • Now you see the source code of your e-mail in a new window.
    • Find the base64 part, copy and paste it and you are ready.
  • Please take notice of the closing double quote.
