Step 01: Create your HTML signature

To create your customized email signature, you need a HTML file containing your data. There are several ways to create a HTML file for your signature:

Use a HTML signature generator service

HTML signature generators are a good choice if you don’t know how to code your own HTML. On the web, there are several free and paid generators, offering a variety of templates and design options. Paid services usually provide additional features like stats, administration panels to manage multiple signatures for your company or advanced templates.

Code your own HTML:

If you know a little HTML, you can code your own HTML signature. However, be aware that email clients only know limited CSS, so write your HTML the „old school way“ using only inline CSS and test the design of your signature thoroughly in different email clients.

Pro tip: Adding images to your signature can be a pain. Therefore, we recommend to convert your images to base64 and add the base64 code as source to your image tag.

Hire a webdesigner:

If you’re already working with a webdesigner or a webdesign agency, they can surly design and create a HTML signature for you. Ask them to provide you with a HTML or TXT file that contains only your signature between the opening and closingtag. The file should not contain anyortags.

After you’ve got a HTML signature file, you can add the formatted HTML signature to Apple Mail.
