Until 30 days AFTER the campaign end date.   For example, if you create the campaign in mid December, with a Start Date of January 1st, and an End Date of February 28th, you will have reporting access from mid December, all the way through March 30th.   Don’t worry though! If you don’t get all the customer data, we keep everything securely on our cloud server. Which means if a significant period of time has passed, we can still get your customer data and send it to you.
