I like how it integrates with my accounts, you can also add multiple emails addresses in one campaign so if someone writes me back twice then both will be counted as 1 star rating for this seller account which helps when amazon does not allow 3 stars ratings anymore! The only thing i dislike about prosellers are their prices they charge too much compared to other services out there but overall good product and service provided! If you're looking into having some form of customer support from outside sources or just want help creating effective marketing strategies using tools such as autoresponders etc then go ahead and try them out! It really helped us build our business especially since we were able to have consistent contact points with clients via e-mail.
