How to Create HTML Signatures in Thunderbird without Learning HTML

What’s your email signature look like? One of those drab, plain text affairs with long, ugly URLs? Are you envious of the glorious, rich text signatures replete with images, hyperlinks, and digitized signatures that you get from your classier correspondences? Envy no more, good chum, because you can create your own HTML signature in Thunderbird without even learning HTML.

Step One

Create a new blank message in Thunderbird by clicking Write. We’re not actually sending an email here; we’re just using this message as a workspace.

Step Two

Type out your signature and format it using the formatting toolbar in the composition window. Make everything just like you want it to look in your signature.

Step Three

Personally, I like to include an image in my signature. If you’re pretty enough, you could even include a headshot, but lookin’ good isn’t really my department, so I’m going to use a logo. There are two ways to do this: attach it or embed an image on a web server. If you attach it, then every single email you send out will have your signature image attached. This’ll add a few KBs to your file size, which may or may not be an issue for you. But the real drawback is that your recipients will never know if you actually sent them an attachment other than your signature image. I don’t really like that, so I usually opt for the remotely hosted image. The drawback of that is that, by default, most web clients block remote images. But once you start emailing someone regularly, they can start accepting remote images, so really, that’s only an issue for your first message.

Anyway, to insert an image, click the Insert button in the formatting toolbar and click Image.

If you’re attaching your image, you can browse for it by clicking Choose File… If you’re using a remote image, copy and paste the location into the Image Location field. You can also add alt text and tooltip text if you’d like, or you can select Don’t use alternate text to forgo this.

Step Four

You’ll also probably want to include a link. To create a hyperlink, highlight the text you want to use as your anchor text, click the Insert button, and choose Link.

Type in the destination URL and click OK. I don’t recommend attaching the source of the link to the message.

Step Five

Once you have your signature just the way you like it, click Edit and choose Select All (or press CTRL-A on your keyboard). This will select all the text.

Step Six

Click the Insert menu and click HTML.

Step Seven

This will show a dialogue box with the raw HTML code for the signature you just created. Press CTRL-A and then CTRL-C to copy the raw HTML code to your clipboard. Click Cancel.

Step Eight

Click Tools and choose Account Settings.

Step Nine

In the box below Signature text, paste your HTML code. Make sure Use HTML is checked and click OK.

Now, when you compose a new message, your custom HTML signature will already be inserted.

Remember that if you’re embedding an image from a remote site, the recipient may have to enable images from your email address before they can see your logo.

Create HTML Signature in Thunderbird

That’s certainly not the only way to get a rich text HTML signature into Thunderbird, but in my opinion, it’s the easiest, especially for those who feel daunted by raw HTML code. With this method, you can create your signature in a WYSIWYG (what you see is what you get) and save it for future use.

      Check if two options below:

      are unchecked and

      “Signature Text : use HTML…” is checked.

      Hope this help. :)

  78. Mardi

    Thanks so much. It worked for me too. My only issue is that it’s coming out double spaced when I don’t want it to. The wording I copied isn’t double spaced. Can anyone help. Thanks

  79. Mike

    It can be done and explained way easier and faster…
    Open a new message, add text, links, images – edit it as you want.
    Then File->Save As->File
    This will save the message as html file that can be chosen for a signature in given account settings.

    Plus of having it on file is that if you want to set mail accounts anew, it’s easier to point to a proper file and you can edit or view it on another program if needed.

  80. Mark

    I had an HTML signature before, but wanted to add an image with a hyperlink. Couldn’t figure out how to insert the hyperlink code into the HTML. This was exactly what I needed. Thanks a ton.

  81. Maggie Danesfahani

    Thank you so much. Really helpful

  82. rosco331

    Thanks a million, worked like a charm!

  83. Frank

    Why does the image I chose only work once, then I have to re-add it after every single email? An answer would be great. Thank you.

  84. Martin

    Oh wow!! That was surprisingly easy!! Thanks for the straightforward instructions…now how do you get it to put the signature at the end of each response instead of all the way at the bottom of a long email chain?

  85. Ted Coakley III

    EXCELLENT article/instructions. Exactly what I needed.
