Measure unsubscribe rate alongside email gains
Understand the audience cost of a campaign’s response.
Match the counts to one send
If 10,000 emails are delivered and 45 people unsubscribe, the send-level unsubscribe rate is 0.45%. Keep complaints and bounces separate. Record unique useful clicks or purchases on the same send.
Compare like message types
A sale announcement and a routine newsletter may produce different reactions. Segment by list source or subscriber age to see whether the offer or audience is driving the change. Check counts before interpreting a large percentage from a tiny segment.
Evaluate repeat effects
If clicks rise while opt-outs also rise, estimate whether the extra qualified actions are worth losing future reach. Review list growth, repeat engagement, and response quality over several sends rather than deciding from one message.

Measure clicks per impression. Use the same click type, placement scope, and date range across comparisons.
