Template & Reminders

Is there a way to edit the CSS of the Template and Reminders? I tried some inline but looks different on every email client.

I need to do this because for example the logo show extremely small on gmail and domain emails, while looks fine on Yahoo mail. I want a little more control on those styles. Is it possible?


I think the only option is using inline CSS.

I recommend using a site like this to see what’s supported:
