I like how easy it is to use and understand for users that are new into this type of marketing strategy. It's also very affordable compared with other services out there in the market today. Nothing really at this time because we haven't used everything yet but if you do get started using their service then make sure your website has an opt-in page or form where people can give consent before they start receiving emails/texts etc. We're trying to grow our business by getting potential customers through email campaigns so far no complaints about them thus far!
