Email analytics

Measuring what happens after you send: bounces, opens, clicks, conversions, unsubscribes and complaints.

In practice

Opens are the least reliable number, since some mail apps load images in advance and record an open the reader never made. Clicks, conversions and bounces are firmer.

Verification and sending

Bounces are the metric verification affects directly. A falling hard bounce rate after cleaning a list shows it working.
