Reports API

Message key performance indicators and individual subscriber interactions can be reported through the Reports API. This is a complementary report to the /v2/subscribers/{id}/emails/{messageid} report. Bulk message open and click events peak about 12 hours after delivery and decreases in activity significantly after 4 to 6 days. Wait several days after delivery to request a report to capture the most event information. Reports are retained for 7 days, then they must be requested again.
