I had this app before and their subscription is too expensive. The fact that we are paying the subscription, sending messages or email will consume the amount of money you spent on the app and you had to have a credit again so you can send messages and emails. Why you don't make the messages unlimited since we are paying a subscription. I don't get the point why we have to buy credits just to send messages at the same time we are paying you our subscriptions. Not worthy not at all.
