I've designed hundreds of emails. I used to handcode them in HTML before the likes of MailChimp came along and made it much easier to impliment HTML emails. Shown here are some designs for Starbucks, Jury's Inn, Jaguar and The Koin Club.
I worked at The Koin Club for a year and during that time designed many email campaigns for product launches and promotions. This example features my coin and pack designs for Roald Dahl's Matilda and The BFG.
