Thanks for pointing these out.
Anyway, i've already found workaround for that, let me explain :
1. I will make a rate like 1 email every X
2. I will make a limit, when the user reach the mail limit he have to host the mail script himself
3. Users will have tokens assigned to get data (token : rate, nb_of_sent_mails, xxx
It's to avoid spam too
Of course these will come to next updates
The idea behind it is great but I would love for the plugin to have an option to setup the traffic to one we desire, not only yours.
yes of course, the plugin is currently only like 0.1 beta xD
