Work out what share of delivered emails were opened, the first gate in any email funnel.
The open rate is the share of emails delivered that emails opened represents, expressed as a percentage. The same figure is also shown per 1,000 and as a "one in every N" odds statement, which is easier to reason about when the rate is very small. Absolute counts hide scale — a rate normalises the number so you can compare periods, channels or cohorts of different sizes, where higher is better.
