Every good Outlook signature is an HTML signature. If your signature is a simple image it will get distorted in different devices. If your signature is simple text then it’s going to look unprofessional.

Creating an Outlook HTML signature is well worth your time. Done well, it will make a great impression on your recipients and encourage people to get in contact.

How to manually add an HTML signature to Outlook

Adding an HTML signature to your Outlook is actually very easy, but it’s a bit tricky too.


If you’re using Wisestamp there is no need for any of these steps, since our tool builds your signature in HTML, and after you’re done auto-installs your signature in Outlook with no further manual action needed

1) To begin with you’ll need a pre-made signature in HTML code. If you went through the previous step in this guide then you already have your signature ready (you can also grab this outlook html signature template)

2) The next step is to paste your raw HTML in this free online HTML editor. All you need to do is drop the code in the right side panel. Look to the left panel to make sure everything is in place like intended (see my example below)

If you added an HTML signature with an image see that there is some white space left between the image and the text. If you added icons, see that they’re not stuck together. After that, select the entire rendered HTML from the left panel and copy it so you can paste it in Outlook. 

3) The final step is to open your Outlook signature settings and paste your rendered HTML signature directly into the integrated Outlook signature editor. Use the guides below to see exactly how this is done in your respective version of Outlook.

How to create an HTML signature in Outlook Mobile?

Outlook does not permit a rich HTML signature for mobile devices. You can create a plain text HTML signature. In actuality, all signatures in Outlook, both in Android and in iOS are made with HTML), but their signature settings are limited.

This means that you can add text and hyperlinks, but you will not be able to use images, or give your signature text sizes and colors. We’ll update you here, if this changes.
