Here in the AppSumo Q&A to other people's questions in one reply you said "ReplySync doesn't count the number of messages, we count active contacts per month, a contact is someone that has been contacted through an automation" and in another you said "Multiple AI messages will use 1 credit per AI generated message", so I wanted to get clarification on whether you count the number of messages or not, since one reply said you don't you just count the contacts and the other said that you do count each AI message.
