We have added a quick report to show many of each type of email (drip, list, autoredponder, one-to-one, etc.) you have been sending. This is available under Administration -> Overview. The report will display the amount sent, broken out by day. If no emails of any type were sent on a given day, that row will be omitted from the report. You can sort by various date ranges as well as your billing cycle.
