MailPusher is one word. Logo needs to be modern and flat design. We are looking for something simple, not too complex, possibly with a mascot. Logo should either be square, or a wide rectangle, not a tall rectangle. We prefer a small / simplistic number of colors. Company website prominent color is #2196f3 blue.

Incorporate some kind of pushing possibly into the logo. Maybe an envelope getting pushed somehow, like an arrow, or something pushing... Or something that would resemble a notification / alarm.
