Update 4: Liking clean lines and icons in design
Update 3: We need to have clean header / hero image, room for single column plain text and a footer ... also useful to have ability to have side by side columns
Update 2: Please add mobile previews of your designs
Update 1: Our customers will predominately be reading these emails on their phones so please design for mobile reading. That means simple clean layouts with only a few bits of copy in each email. Please keep to basic colour scheme ... we are tending to like black, grey, white & maybe some blue ... (or other contrast colours that you think might work).
Modern clean layout drawing from: Apple, Uber, Pebble, Xero, ...
We will be sending from MailChimp at this stage but don't be too constrained by this.
