Site logo

Hello, last week i have download and use this awesome plugin, but i have only one problem and i hope you help me resolved…
in the Header image i have use SVG logo, you know its best quality, but the problem is that if email is send to Hotmail its fine but for gmail not, all gmail messages comes only with site name only.
i have try PNG and it works for both (Hotmail and gmail) but logo become pixelated for small size or too big for normal size, so i just wandering if there is something i can do to use SVG logo and its show on gmail messages.
Thank you
