Net Promoter Score Survey Email Benchmarks
NPS survey emails measure customer loyalty by asking a single question: how likely are you to recommend us to a friend or colleague? The simplicity of the question drives higher response rates than longer surveys, making email the most effective distribution channel for NPS programmes.
| Metric | Average | Above Average | Excellent |
|---|---|---|---|
| Open Rate | 35-48% | 52%+ | 62%+ |
| Click-Through Rate | 8-18% | 22%+ | 30%+ |
| Survey Completion Rate | 5-12% | 15%+ | 22%+ |
| Click-to-Open Rate | 25-38% | 42%+ | 55%+ |
| Unsubscribe Rate | 0.2-0.4% | Below 0.15% | Below 0.08% |
NPS Benchmarks by Survey Type
| Survey Method | Completion Rate | Best Use Case |
|---|---|---|
| Embedded one-click (email) | 8-15% | High-volume, transactional |
| Single-question landing page | 5-12% | Most common, balanced approach |
| Multi-question follow-up survey | 2-5% | After NPS score, for qualitative feedback |
Why NPS Email Benchmarks Matter
NPS is the most widely adopted customer loyalty metric, used by two-thirds of Fortune 500 companies. The email that delivers the survey directly determines the response rate, which in turn determines the statistical validity of your NPS score. A low response rate produces a score that may not represent your actual customer base.
Best Practices
- Send NPS surveys to customers who have been active for at least 30 days to ensure they have enough experience to form an opinion
- Use a single-question format in the email body with clickable score options rather than requiring a landing page visit
- Follow up with detractors (scores 0-6) within 24 hours to understand and address their concerns
- Send relational NPS surveys quarterly or biannually and transactional NPS surveys after key touchpoints such as support interactions

Frequently Asked Questions
A good NPS email response rate is 8-15%. Rates above 18% are above average. Embedded one-click surveys yield the highest completion rates. If your response rate is below 5%, review subject line clarity, email design simplicity and whether the survey is mobile-optimised.
No. Segment your NPS survey to active customers who have been using your product or service for at least 30 days. New customers and inactive customers will skew results. A well-segmented NPS survey achieves response rates 2-3x higher than broadcast sends.
Send relational NPS surveys quarterly. Sending more frequently risks survey fatigue and declining response rates. Transactional NPS surveys can be sent after specific touchpoints without affecting the relational survey schedule.
