How to Create HTML Email Signatures for Microsoft Outlook 2011 On a Mac

How to Create HTML Email Signatures for Microsoft Outlook 2011 On a Mac

Having a HTML signature in your emails is a great way to look professional, unique and to promote yourself but creating one isn’t so straightforward. You have to design your signature layout, write up the HTML codes and know how to install it into your preferred email program. In this tutorial, I’ll go over some HTML tips for writing up the HTML codes and give instructions on how to install the email signature into Microsoft Outlook 2011 on a Mac.

There are 2 sections in this tutorial:
Section 1: HTML Tips For Coding Your Email Signature
Section 2: Installing your HTML signature into Outlook 2011 on your Mac

If you have basic HTML skills and know how to work with a web server, you will learn how to write up your HTML codes correctly by following Section 1. If you don’t know anything about HTML coding or just don’t have the time to deal with it, you may consider hiring us to do it for you. Please visit for more info. Go straight to Section 2 if you already have your HTML email signature file created and just need installation help.


Step 1.1: Design Consideration

Today, emails are viewed on desktop computers, laptops and on tablets and smart phones. It is best to keep the width of your HTML email signature as narrow as possible for the best result. Most modern mobile devices have a default width of 640 pixels so it is best to keep your design under that to ensure that the layout doesn’t break on smaller screens. From experience, designs that have a width of 320 pixels and under are the most consistent. NOTE: If your signature design for Outlook 2011 have a width larger than 320 pixels, you will have to manually adjust the width of your signature each time you compose a new email.

Step 1.2: Signature Information

MYDESIGNPAD Signature design 2012

Decide what and how much info you want to display on your signature. For this demonstration, I’ll be using my own HTML email signature design with a picture link to my website, name, title, email and some other text links. Feel free to use my design as a template. To see the HTML codes, find “View Source” in your browser menu.

Step 1.3: Writing the HTML Codes

Here are some basic but important notes to keep in mind as you design your signature. One major obstacle in designing HTML e-mail templates is that there are so many different e-mail clients out there (most if not all can’t handle CSS and HTML like our internet browsers can) so you have to keep your design and codes as simple and straight forward as possible.

  • Use tables for basic layout. The CSS float property is not supported in Gmail or Outlook, making CSS layouts impractical.
  • Use inline CSS. The style tag is not supported in Gmail, and support for CSS selectors is spotty.
  • Use only basic CSS properties. E-mail clients tend to be very picky about which CSS properties they support. Campaign Monitor has a great summary of CSS support in e-mail to use for reference.
  • Use absolute URLs. Relative paths won’t work for an e-mail signature. So all your links need to be absolute URLs.
  • Link to images. I personally dislike e-mail signature images as attachments (it makes it easy to mistaken that image as a legitimate attachment). Because of this, I recommend linking to your images by placing them on a web server rather than including them as attachments. See Step 4 for more info.
  • Exclude HTML, HEAD, and BODY tags. When we get ready to save your HTML signature into Mail, make sure that only the relevant HTML is included in your document.

Step 1.4: Saving and Uploading your images to a web server

Since we want the email signature to load quickly, make sure to optimize your image with Adobe Photoshop by doing a “Save for Web.” Upload your images to your web server and copy the public path. The public path (absolute URL) should look something like this: “” Copy image link and insert it into the appropriate img tags of your HTML file.

Step 1.5: Save File and Preview

Once you have your email signature coded, save the HTML file to your Desktop and call it “signature.html” Locate file and open it with Safari or Firefox (not tested with other browsers).


Step 2.1: Copy Signature Design

With your “signature.html” file opened on Safari or Firefox, press Command+A on your keyboard to “Select All.” Then press Command+C to copy design.

Copying HTML signature in Safari

Step 2.2: Create Placeholder Signature

Open Outlook > Preferences > Signatures. Click the plus button on the lower left to create a new signature. Give it a name. If there are any content in the big right signature window after you’ve clicked the plus icon, delete it. It usually displays your first and last name. In my case, it’s MYDESIGNPAD.

Opening Outlook preferences

Signature Settings

Add signature

Step 2.3: Replace Default Signature

Click anywhere on the big right signature window to have it selected, press Command+V on your keyboard to paste in the signature design that you copied from your browser.

Inserting HTML signature

Step 2.4: Confirm Default Signatures Setting.

Click the “Default Signatures…” button on the lower right. Click to open pop-up window on the right column. Select the signature that you created and press “Ok.” Close window and quit Outlook. Then reopen Outlook. Open up a new compose email window and your new signature should be there.

Confirm default signature

Testing new signature

    Kiki says:

    Thanks – very nice steps. I’m wondering if you’ve ever had any difficulty sending HTML signatures from an Exchange account? I can successfully send a signature from Gmail (through Outlook) and it works fine, but getting it to work from my work email (which uses Exchange), it does not send the images properly (when I open the email in Gmail, Hotmail, etc.) — happen to have any insight or clues about that or know of any solutions?

    Nice guide – only comment would be to add,

    “Once the signature is selected (it will go blue), press “Command + C” to copy it.” to section 2.1.

    Thanks! :)

    Good Morning – I’ve created the HTML using Dreamweaver and have saved all of the image files on my public dropbox folder, copied the dropbox public link, etc. and the signature shows up fine when I test it… however, when I copy/paste the email and send a test email, the icons do not go to the appropriate social media page?

    thank you. on my PC i can have one signature for new e-mails and another for reply / forwarded mails. is that possible on outlook for mac please?

  10. April 9th, 2013

    Tim Cai says:

    James, on Apple Mail, multiple signatures may be assigned to each email account. When composing a new message or for a reply, there is an option to select which signature you want to use if there is more than one available. On Outlook for Mac, I am not sure. If I find out, I’ll be sure to post about it here. If you figure it out before me, please help me and others by posting your answer here. Thanks!

  11. April 9th, 2013

    james says:

    thank you. ok, same as apple mail. as long as you have created more than one signature you can chose which one to use once you are in the body of the compose area.

    Is it possible to link a vcf card without opening a browser?

  26. September 19th, 2013

    Tim Cai says:

    As far as I know, you cannot link to a vcf without opening a broswer. As the vcf card needs to be downloaded in order for it to sync into your address book, it have to open up a web browser for the download process.

    Hello just wanted to give you a quick heads up and let you know a few of the pictures aren’t loading properly.
    I’m not sure why but I think its a linking issue.
    I’ve tried it in two different web browsers
    and both show the same outcome.

    Maik says:

    Do you have any solutions, when outlook is changing the sizes of the fonts sometimes by it self? I wrote a perfect html-code for the signature, defined all system-fonts and sizes, but outlook is so crazy and changed it! Has it something to do with some standard formats in outlook?

    With mac all works fine, but in outlook…

    Miriam says:

    I also made the signature like you did and it worked as well, but only on my mac/outlook. When I send a mail out, the signature brokes. Sometimes direct at the clients mail-program, sometimes, when they send me an answer …

    Does anybody figured out how to fix this?
    I’ve heard about putting an html file on the mac system, but I don’t know where, which folder?!
    For windows, there is a folder for that …

    Looking forward to hear from you :)

    Tim, you created 3 html signatures for us and one of my colleagues needs to re-install his into Outlook for Mac 2011 but is using OS X Mavericks. Is there any change to the instructions with Mavericks? Because he is experiencing problems with sending mails when the signature has been copied and pasted into Outlook. If he removes the html signature, Outlook sends perfectly fine. Very odd???

    Please excuse my ignorance but I am a print designer trying to meddle with the world of email signatures and (as expected) I am failing.

    I have set up the signature in Photoshop, sliced it up, attached the links to the sections that I want to be buttons and then saved the entire thing as HTML and images. However, I’m a bit stumped as to what I need to do next. Am I missing a step? Perhaps then taking all of this into Dreamweaver next?

    Again, apologies for the ignorance here but it really isn’t my field. When I go into outlook to try and import a signature I can only import an image or create a hyperlink?



  46. October 8th, 2014

    Tim Cai says:

    the email signatures work best when it is coded with simple tables and cells. You also need to upload and host your images on a web server in order for the images to load remotely so that it doesn’t get sent as attachments.

  47. October 22nd, 2014

    I have followed the instructions as above, but the images in the signature are not showing in Outlook 2011 for Mac. The same signature is set up for several users on a PC without problem, so it is not a problem with where the images are hosted – any ideas?

    Hi Tim,

    Many thanks for the insight and guidance. I do a challenge and will appreciate your assistance.
    When I copy and paste the HTML signature in Outlook 2013 client during signature set-up, the following happens:

    1. The telephone icon disappears and some fonts change from Helvetica Nueue to Times New Roman.
    2. The email address and phone numbers is displayed are underlined.

    Please advise.

    Everything worked perfectly; however, I am wondering if there is a way to show a text-only version if the receiver does not support html messages. Thanks,
