title: Why is my mails staying in “backlog” of Mandrill?
body: <p>at previous hour we reached the number of maximum limit of sending emails per hour which is not surprising since we know our limit per hour to send. However, after an hour passed I assumed that the rest of the emails will be sent automatically. It did not work that way. Now I have over 800 per hour to send and I sent 0 in this hour, at the same time, I see that 139 emails are backlogged from previous hour. Could you please help me how can I send those?</p>
