We love healthy food snackers Graze, and with this great example of a re-activation campaign it's easy to see why. To try and tempt old customers back, they are letting them know about their new brownie (smooth move!), as well as offering three half price snack boxes. There's a nice clear call-to-action, ALT text, but no 'view online' link. All in all, a very nice email, with mobile optimisation to boot (Next Pin).
