Unfortunately, an un-branded email looks suspicious and unprofessional nowadays. You'll get more complaints and unsubs than ever versus a well-crafted (not over-the-top) engaging layout.

I'm going off topic, but as a designer and a front-end developer, I get frustrated when the developed product isn't a 1:1 representation (when sending out the work to get coded). The end result should be a pixel perfect match of the artwork. Nothing is impossible translating an image to a website/app.
