Thank You Note Email Benchmarks
Thank you note emails are simple, gratitude-driven messages sent after a purchase, subscription or meaningful interaction. Unlike transactional order confirmations, these emails have no functional purpose other than expressing appreciation. Their value is entirely relational — building goodwill that pays off in retention and lifetime value.
| Metric | Average | Above Average | Excellent |
|---|---|---|---|
| Open Rate | 48-62% | 68%+ | 78%+ |
| Click-Through Rate | 5-12% | 18%+ | 28%+ |
| Click-to-Open Rate | 12-22% | 28%+ | 38%+ |
| Unsubscribe Rate | 0.1-0.3% | Below 0.08% | Below 0.04% |
Why Thank You Benchmarks Matter
A genuine thank-you email is one of the simplest yet most overlooked retention tools. Customers who receive a post-purchase thank-you note show measurably higher repeat purchase rates and customer satisfaction scores. The email does not need to drive immediate clicks to be effective — its value is in the relationship it builds.
Benchmarks by Content Approach
| Approach | Open Rate | Repeat Purchase Impact |
|---|---|---|
| Pure gratitude (no links) | 48-58% | +5-10% repeat rate |
| Gratitude + social follow | 50-60% | +3-7% repeat rate |
| Gratitude + product tips | 52-62% | +8-14% repeat rate |
| Gratitude + soft upsell | 45-55% | +5-12% repeat rate |
Best Practices
- Send thank-you notes from a real person's name rather than a generic brand address to increase authenticity
- Keep the email short — 3 to 5 sentences is ideal. Length dilutes the emotional impact of gratitude
- Do not include promotional content in a pure thank-you email. Including an upsell transforms the email from grateful to transactional
- Consider handwritten-style design or personal sign-off to reinforce the human-to-human nature of the message

Frequently Asked Questions
Yes. Customers who receive a genuine post-purchase thank-you email show repeat purchase rates 5-15% higher than those who do not, according to available industry data. The effect is strongest for first-time purchasers who are still forming their impression of the brand.
