Faster Bulk export of data
At every ESP i have used perviously, SalesForce, Responsys, Smart Focus, Campaign Monitor, Mail Chimp and Cheetah Mail, extracting data would take anywhere from seconds to about 5min max, dependent on file size.
Extracting data from Bronto, takes hours even when the file size is in the thousands. This lag time doesn't facilitate for agile marketing process.
This is a real weak spot compared to competitors.
