The actual markup MJML generates is terrifying, and can be very large payloads. A simple hero graphic, some styled body text, a few buttons, and a footer was around 60KB/message. It got gnarly for us as our MTA had a max-payload size per API 'send' call (Mandrill) so our max send rates were partially constrained by MJML's fat markup.
But totally worth it to not spend _as_ much time satisfying the mail clients of the world.
