I've read messages here from people who say that some usage that exceeds the credits is billed without notice.
That's right and normal.
But I wonder, if we know that we have 5000 credits per month to get 5000 emails per month, surely we can set a limit in your program, right?
Otherwise I too would be afraid of having billed something I didn't expect.
Don't tell me anything else, just tell me if I can set the limit based on my credits, so that it doesn't need my attention, at 5000 the program warns me and says, from now on you've run out of credit and it stops. Thanks.
