These deliverability benchmarks are calculated from the deliverability results based on all email campaigns sent system-wide in the last 90 days.

* The delivery rate is simply of messages sent minus the number of messages bounced divided by the number of messages sent.

** The open rates are measured from the HTML-based messages and these statistics underreport the actual number of opens because an open requires a zero-pixel image in the message to be rendered in order to be counted. However, the click-through rates are more accurate since they are not subjected to the differences in how the message might be rendered.
