Frequently Asked Questions
What is a good email open rate?
Benchmark varies by industry. Overall average: 20-22%. Excellent: 30%+. Good: 20-30%. Fair: 15-20%. Poor: <15%. B2B generally higher (25%) than B2C (18%). Personal newsletters (Substack) often 40-60%. Factors: audience quality, subject line, sender reputation, send time. Compare to your own baseline and industry, not universal benchmarks.
What is a good click-through rate (CTR)?
Average CTR: 2-3%. Excellent: 5%+. Good: 2.5-5%. Fair: 1.5-2.5%. Poor: <1.5%. CTR measures engagement with content and CTAs. Higher CTR = compelling content. Low CTR with high open = subject line promises didn't match content (bait-and-switch). Optimize: Clear CTA, scannable layout, relevant links, mobile-friendly design.
How do I improve email open rates?
Subject line: Curiosity (not clickbait), benefit-driven, personalization, 40-50 characters, avoid spam words ('FREE!!!'), A/B test. Sender name: Personal name > company name ('John at Acme' > 'Acme Newsletter'). Send time: Test Tuesday-Thursday 10 AM. Preheader: Complement subject, don't repeat. List hygiene: Remove bounces, re-engage inactive, segment engaged users.
What's a good list growth rate?
Healthy: 2-5% monthly organic growth. Excellent: 10%+ (viral content, strong value prop). Account for churn: if you add 500 subscribers but 200 unsub, net growth is 300. Quality > quantity. Engaged 1,000-subscriber list beats disengaged 10,000. Avoid: Purchased lists (low engagement, spam traps), gated content without value exchange, pre-checked opt-in boxes (GDPR violation).
