What's not to love with this cute email from CB2? It jumped out at me for a few reasons:
1) The bright colors
2) The fresh imagery
3) The well-supporting secondary products
4) CB2 makes bikes?!
And when I got home from work, the CB2 catalog had arrived with the same image on the cover! Looks like they have their marketing channels well-synced.
The only thing I would recommend they do differently is (of course) include more HTML where possible.
