BlueHornet is a great platform for a small or medium size business that is graduating from the "free" platforms and wants more features. It delivers a generally easy to use interface and HTML editor. The concept of segments as implemented by Blue Hornet is not standard, but it allows fairly powerful segmentation capabilities that are easy for a marketer to use. Why choose a more complicated, expensive platform if you do not need or use their advanced features? Whistles and bells are attractive, but a potential user should be realistic about their immediate needs and the needs they will have over the next year. BlueHornet has seen some history of instability. If you need to send mission-critical transactional messages like password resets, it may not be the best choice, but for a budget-conscious email marketer, it is a reasonable option.
