How To Display Signature In Replies, Forwards

Signatures in Thunderbird

Recently I have been wondering how I could get an eMail signature to appear in replies and forwarded eMail. When I write an eMail, the signature is always there, but when I’m responding/replying to an eMail, it is not. This is frustrating when I want people to always know the who, where and how to contact me. Plus, it looks more professional, in my opinion. Right now I have a Name, Title, Phone, eMail Address, Website, and Business Address in the signature.

How do I make sure it appears every time I forward, or even reply to, an eMail? This is actually a simple process and all you need to do is…

Follow These Steps

Step 1: Open your Thunderbird eMail application


Step 2: At the top of your screen, click on “Tools”


Step 3: In the Drop-down Menu, click on “Account Settings”


Step 4: In the left panel of the Account Settings window you will see the wording, “Composition & Addressing,”. Click it


Step 5:  You will notice two Check Boxes midway down. They are labeled, “Include signature for replies” and, “Include signature for forwards.” You will want to check both boxes


Step 6: The final step you will need to do is to click OK


Now, every time you reply to or forward eMail in Mozilla Thunderbird, your eMail signature will appear. This will make sure everyone knows you mean business.

  1. I have been looking for this too but unfortunately this suggestion doesn’t appear to work if you use he signature from a file option for your signature. – I use an HTML file which has my signature text along with a small logo – all I get for replies/forwards is a blank text box with just my name in it (which is the alt txt for the image file)

    1. Hi gbswales
      I have been trying to reproduce the same issue you are having with no avail. It has been working with the HTML signature files, html signature text and basic way I explain in the article on my end. I have tested it on 2 different computers running the same version of Mozilla (45.3.0). So I’m guessing your signature shows when sending emails?
      I did check my view settings and turned on plain text view. This made my signature show the default text only. So you might check that option to make sure it is set to view HTML. Go to “View | Message Body As | Original HTML”. Since I do not know what you have tried I want to give you some options.
      Might be the image file location causing some issues. Is it saved online or is it saved in your computer? The image source that is.
      I would suggest going to our forum and posting your question there. We have many others that might be able to help you with this issue. Here is the link .
      Most of the time these issues can be just a setting that is different or an update from Thunderbird that causes the issue.
      Hate not being able to figure why it works for me and not you. Keep me informed if you find the answer. I will keep thinking on this and if I figure it out I will let you know here.

      1. Thanks for your comments – the image file is a fairly small one that was saved in My Documents and referred to in the signature area for Thunderbird – for replies and forwards as well.  However following your comment I decided to try changing the location of the file and put it in users……..AppDataThunderbird  – referenced from there it does work now for replies and forwards – as you can see below.  I have no idea why the original location worked for new messages but not for replies/forwards but it was your comments that led me to a solution so thank you computers eh!

        1. You are very welcome Clive! I’m so glad that my comment helped you figure out your issue with Thunderbird. Computers for some reason like to challenge us every so often. 🙂

    Interesting that I had the opposite problem for years: I did NOT want my ‘default signature’ to appear in forwards (at least most of them, where I do not add anything to the forwarded text), because some of the recipients might re-forward it, and so on, and my full info would go out to people and places I never had intended it to go — so, when I found the same setting you describe (in SeaMonkey, but it’s 98% like ThunderBird in the Mail function), I was pleased, but did the opposite of what you described! Different strokes…

    1. Alexander Yudenitsch,
      As long as it helped you out in some way or form that makes my writing worth it. In my business I want to make sure all my info is front and center.
      I hate to say it but I have never heard of SeaMonkey. Will have to take a look at that. 🙂

    Jason Shuffield,
    Actually, I had found that setting a few years back, but your comment reminded me of that event, and I found it interesting that we both had a problem with that setting, but for opposite reasons… 🙂
    Netscape became the Mozilla Suite (including integrated browser, e-mail client, composer, and messaging) and, when Mozilla decided they wanted to separate the browser (which became FireFox) and the e-mail (now ThunderBird), a group of developers decided they liked the “suite” idea better, and started SeaMonkey, picking up where MozSuite left off, but keeping the basic Gecko kernel. Some time later, Mozilla decided they wanted to concentrate on FireFox, so ThunderBird also became a spin-off. Many FF extensions/addons work for SM, as-is or with some conversion.
    If you like the ‘integrated suite’ idea, SM might appeal to you. if not, FireFox &/or ThunderBird might be a better fit. The SeaMonkey FAQ is at:

    1. At least my article triggered a memory and that is a win to me.
      The best thing about writing these articles is having readers like you share their knowledge. I would have never known about the history of Mozilla Thunderbird or the SeaMonkey Suite. Thanks for the info Alexander.

      1. Alexander Yudenitsch

        Since SM is still my browser (and e-mail client) of preference, I’m worried that Mozilla seems to be taking FF in a direction which may be incompatible with SM (which uses the FF development as a basis for new releases), and in fact FF itself seems to be losing ground to Chrome — but, since there is nothing I can do about both situations, I try not to dwell on it…

  4. But isn’t there a school of thought that we should NOT include a signature repetitively in an ongoing conversion?? I recently changed my settings to automatically include signature on New Messages only. For Replies or Forwards I click to insert manually. In an extended conversation I only do that on the first Reply.

    1. Alexander Yudenitsch

      Which is why I wanted to achieve the opposite result, as I deswcribed in my reply to Jason Shuffield — but, for a few cases where I know I can trust the recipients, the signature may be appropriate.

  5. I’ve tried this, but my signature block isn’t showing up on replies or forwards, even though the boxes are checked. And I’m just trying to use basic text. Any ideas?

  6. Not to sure why it is not showing up if you checked all the boxes. Make sure everything is set the same way from step 6. When you are doing a reply is your signature showing up at the very bottom or somewhere else? I found that my signature was placed in a spot I did not notice. Also make sure to update your Thunderbird by going up to the Help option and clicking on about Thunderbird. This is where you can see what version your on and update it. Alot of the time it is an update causing the problem. If these do not work head to our forum someone might be able to figure it out for you Just start a new topic with exactly what is going on.
