Currently the Sailthru campaign query table syncs the last 60 days worth of data due to a limitation with the Sailthru API that does not allow users to define dates when making an API call. But depending on your company and Sailthru use case the look back window doesn't need to be that big to ensure the same level of data quality.

99% of actions on our emails happen within a week of sending them. This means that a 60 day look back window does not add a lot of value for us but still syncs a lot of data at the beginning of the month.

Adding the ability to choose a smaller look back window for clients would be a big win, as it can greatly reduce cost without impacting quality of the data.
