Apple email marketing.
The Apple brand is all about simplicity. Before I ever touched my first project at Apple, I spent about a week in brand training. What's great about Apple is that everything they do reflects their brand -- from the way their products work, to the way their associates answer the phones and greet you in the stores.
Everything we did was heavily scrutinized, as it should have been. After all, it's the best way to assure brand consistency.
