Is there a way to get a list of all I sent in a specific period of time?

Hey Jeffrey,

Do you want a record of every send activity that occurred in that time frame, or do you want a list of every email asset that has been sent in that time frame? In other words, do you want a list that shows one row per email asset, or one row per send activity (where each asset can show multiple times if it was sent multiple times)?

An email performance report (http://docs.marketo.com/display/public/DOCS/Email+Performance+Report) will show you a list of all emails that have been sent within a workspace and within a time period that you can specify. It also shows you the first and last activity dates related to that email.

The above will represent every individual send activity only if you don't use trigger or repeating schedule sends - but I don't think attempting to break those down into individual "batches" is necessarily reasonable at scale (unless you have RCE) - you'd have to go into each individual program + export the history and compare over time. That might be acceptable for you if the volume is low.
