I only use the one tool (emailer) and it's great, but there's honestly nothing special about it except that it's a fraction of the cost of the emailer I was using before. The real value that I've experienced so far is the customer support. They answer just about every question I have related to selling online. They've helped me improve my product listing and have even helped me with my PPC campaign and lower my ACoS. I almost feel bad, because I'm only paying for the emailer, but this is my way of paying it forward. I highly recommend them!
