I like that it was easy enough for me as someone with no coding experience at all just how this works so well! The fact you can add unlimited amounts makes sense too since more people means MORE money in my pocket :) Nothing really but good things about using their service is they are always quick (at least when i contacted through support)to respond via email or live chat whenever necessary - very friendly team over there which helped make getting started quite smooth :). If anyone wants something thats super simple yet effective then go ahead and give these guys an option!! You won't regret its worth every penny spent! Its honestly one thing after another we needed help implementing some new features into our ecommerce store from multiple companies who only charged us $60 per month each time while w/o any proof showing ROI's etc.. WOW what were thinking now lol. We got 3 months free trial where.
