Make mobile friendly option

Is your feature request related to a problem? Please Describe: You can't use the signature creator on mobile because of the way things copy over into the email signature creator, so on mobile there's just a splash screen that says it doesn't work on mobile.

Describe the solution you would like: Ideally we would hook into an API that would do this automatically. But, it doesn't look like that is a possibility, so we need more of an "out-of-the-box" thinking.

Does other service/app have this feature? Yeah G-Suite has a pretty dang good API for this kind of stuff.

This Stack Overflow question is probably the best answer to doing by API:
