Why Benchmarks Matter
You cannot improve what you do not measure. And you cannot measure without context. If your cold email open rate is 42%, is that good? It depends on your industry, your buyer persona, and the type of email you sent.
What Drives Open Rates
Subject lines
- Keep it under 6 words. Short subject lines consistently outperform long ones. "Quick question" and "Thought on [company name]" both perform well.
- Personalise with company name. Include the prospect's company name in the subject line.
- Avoid spam triggers. Words like "free", "guaranteed", "exclusive offer", and excessive capitalisation kill deliverability before the subject line even matters.
- Test relentlessly. Run A/B tests on every campaign. Even small improvements compound over thousands of emails.
Deliverability
None of this matters if your emails land in spam. Deliverability is the foundation everything else sits on.
- Warm up new domains for 2 to 4 weeks before running volume.
- Keep daily send volume under 50 per inbox.
- Use multiple sending domains to spread risk.
- Monitor bounce rates. Above 3% and you need to clean your data.
- Authenticate with SPF, DKIM, and DMARC. Non-negotiable.
How to Use Benchmarks
Compare your campaign performance against benchmarks for your own industry and buyer persona. If you are significantly below them, the problem is usually one of three things: poor data quality, weak subject lines, or deliverability issues.
If you are at or above average but still not getting enough meetings, the issue is likely your message, your ICP targeting, or your follow-up sequence. Open rates tell you whether people are seeing your emails. Reply rates tell you whether the message resonates.
