They are very attractive to small businesses who don't even know Mandrill exists. Relatively well known brand, quirky marketing, good integration with other sites/apps, and free up to 2,000 subscribers (which many small businesses can only dream of!). It's relatively simple to make a decent looking email with their UI, even though I'm not a huge fan of it. By the time you hit that 2,000 subscriber limit you're comfortable and stuck. I've used them before, my main issue (apart from price) is their poor automation/segmentation logic.
