Unsubscribe Rate
Unsubscribe rate is the percentage of recipients who opt out of future emails after a given send, calculated as unsubscribes divided by delivered emails.
In depth
Unsubscribe rate measures audience fatigue and relevance mismatch: when people consistently opt out, your content, frequency, or targeting is misaligned with what they expected when they joined your list. A modest unsubscribe rate is healthy because it self-cleans disinterested contacts, but a sudden spike after a specific campaign is a clear warning that the message missed the mark or the cadence felt excessive. Mailbox providers also weigh opt-outs alongside spam complaints when judging your sender reputation.
In a quiz-funnel workflow, unsubscribes often climb when leads who entered for a single scorecard result are pushed into unrelated promotional blasts. A common pitfall is treating one quiz opt-in as blanket permission to email about everything. To keep the rate low, set clear expectations at capture, segment follow-ups by the lead's score and stated interest, and offer a preference center so contacts can dial down frequency instead of leaving entirely.
Example in practice
Frequently asked questions
What is a good unsubscribe rate?
An unsubscribe rate below about 0.5% per send is generally considered healthy for B2B email. Rates climbing above that, especially after a specific campaign, usually point to relevance or frequency problems.
Are unsubscribes always bad?
No. A steady, low level of unsubscribes naturally removes disengaged contacts and keeps your list focused on interested leads. The concern is a sudden spike or a chronically high rate that signals deeper targeting issues.
How do I lower my unsubscribe rate?
Set clear expectations at sign-up, segment so each contact receives relevant content, and offer a preference center to adjust frequency instead of opting out. Tailoring follow-ups to a lead's quiz result keeps messaging relevant and retains subscribers.
