Hi Ryan,
Here is the solution for you…
First head over to Gmail > Settings > All Settings > General and scroll to the signature section
Now right click inside the signature box and open the inspect window
Locate the HTML and after ltr;"> Insert your signature HTML code.
Note: I also add some breaks at the start to push the signature down the page a little. To do this add <br><br> before the HTML code. Alternatively, press return when you head back to the signature page.
Head to the bottom of the page and save changes.
Your signature will now be complete
