Supplementary notes
The source provides the following information: "Information captured from high volumes of monitored email accounts (seeds) controlled by senders to sample mailbox providers’ placement decisions irrespective of user-initiated or engagement-based filtering. For new programs with little or no history of subscriber interaction, seeds can provide an accurate assessment of inbox placement." Figures for periods prior to Q3 2017 come from previous reporting.
