Objective: Create a custom email signature
The UI/UX of updating your signature in Gmail settings is limited. If you want more than simple text and images you should create it in HTML. This lets you use tables, colors, and more special formatting.
Start with a template like mine.
or use a more common style such as Ricowere’s signature.
Copy the HTML code. Open your favorite text editor and start making it your own. Drag the file to your browser URL and you’ll see your changes.
Once you are happy with your signature highlight the elements in your browser and copy paste it to the Gmail signature field.
