How far back can I go in retrieving data? Specifically, how long can I access the specific email addresses of recipients who received, opened or clicked links in an email?
I thought I had read it was 30 days somewhere, but I can't find it again.
That is a GREAT question (and one I had to look up myself!)
It looks like data is collected for 85 days following a campaign, and remains available for upto 90 days. After 90 days(from the start of the campaign) the data is then deleted from the system and no longer available (however you can always export it in the event that you anticipate needing access to it longer).
Just a suggestion, it might make sense to put this in the API docs, so applications can build in controls to prevent requesting data after the 90 day period.
