Ability to limit sending allowance by APIKEY
Ability to determine a limit of emails to be send per sub-accounts per calendar year or month or week. i.e An account has a 1M yearly volume but can assign a limit of 100k for sub-account A, 200k for sub-account B, etc...Basically breaking down the allowance per sub-account.

It would be great that if I have a monthly limit, if I reach that limit MailJet stop sending email and send me an email letting me know.
