Email Marketing Benchmarks 2025: Open Rates, CTR & Deliverability
Email marketing benchmarks for 2025 — average open rates, click-through rates, unsubscribe rates, and deliverability standards broken down by industry to help you evaluate campaign performance.
Updated: 2025 | OwlClaw Digital Marketing Benchmarks
What are email marketing benchmarks?
Email marketing benchmarks are industry-standard performance metrics for open rate, click-through rate (CTR), click-to-open rate (CTOR), unsubscribe rate, bounce rate, and list growth rate. They define what constitutes average, good, and excellent email performance — measured across billions of campaigns sent by businesses of all sizes globally.
Since Apple Mail Privacy Protection (MPP) inflated open rates from late 2021, industry benchmarks now distinguish between "privacy-affected" open rates and true engagement metrics. CTOR (clicks ÷ opens) and conversion rate are now more reliable engagement signals than raw open rate for Apple-heavy audiences.
Email marketing remains the highest-ROI digital channel with an average return of 42:1, but performance varies significantly by industry, list quality, and send practices. This benchmark report compiles data from Mailchimp's Email Marketing Benchmarks, Litmus's State of Email, Campaign Monitor's annual report, and Klaviyo's ecommerce email data — covering open rates, CTR, bounce rates, unsubscribe rates, and deliverability metrics across major industry verticals.
Key Benchmark Summary
Average email open rate across all industries: 21.5% (note: inflated by Apple MPP privacy — true open rate may be 5–8% lower).
Average email click-through rate: 2.3% of all recipients; click-to-open rate (CTOR): 10.5%.
Average unsubscribe rate: 0.1% per campaign — above 0.3% signals list quality or relevance issues.
Email deliverability benchmark: 95%+ inbox placement rate is standard; below 90% indicates sender reputation problems.
Average email marketing ROI: 42:1 — every £1 spent returns £42 in revenue.
Welcome email open rate: 50–60% — 3× the average campaign open rate.

Strategy Recommendations
Implement SPF, DKIM, and DMARC Authentication
Quick WinGmail and Yahoo now require SPF, DKIM, and DMARC authentication for senders of 5,000+ emails/day. Without authentication, deliverability drops sharply. Configure all three in your DNS settings — this is a non-negotiable foundation for email deliverability.
Segment Lists by Engagement Tier
Quick WinCreate engagement segments: Active (opened in last 30 days), Warm (opened in 30–90 days), Cold (90–180 days), Inactive (180+ days). Send full campaigns to Active, re-engagement sequences to Warm/Cold, and sunset Inactive subscribers to protect sender reputation.
A/B Test Subject Lines on Every Campaign
Quick WinSubject lines with personalisation (first name) increase open rate by 26%. Questions outperform statements. Numbers and specifics (e.g. "7 ways" vs "Ways to") consistently outperform vague subject lines. Test one variable at a time on a 20% sample before sending the winner to the full list.
Build Automated Lifecycle Email Sequences
Medium TermAbandoned cart (30:1 ROI) and welcome sequences (15:1 ROI) dramatically outperform one-off newsletters. Build a 3-step abandoned cart sequence (1 hour, 24 hours, 72 hours post-abandonment) and a 5-email welcome series as your first automation priority.

Email Marketing Benchmark FAQs
Average open rates vary by industry — non-profit (40.2%), education (35.5%), and government (34.8%) are highest; software (15.2%) and retail (18.4%) are lowest. Note that Apple Mail Privacy Protection inflates open rates by 10–15 points for consumer lists. Use click-to-open rate (CTOR) — target 10–15% — as a more reliable engagement benchmark post-MPP.
