TL;DR
Track reply rate as your primary metric, not opens or clicks. A positive reply rate above 5% is good, above 8% is excellent. If you're below 3%, something is broken. See the benchmark table below and use it to diagnose where your campaigns are underperforming.
The metrics that matter
Metric | Good | Great | Excellent |
Positive reply rate | 3–5% | 5–8% | 8%+ |
Meeting booking rate (of replies) | 30–40% | 40–60% | 60%+ |
Bounce rate | <2% | <1% | <0.5% |
Deliverability (inbox placement) | 95%+ | 97%+ | 99%+ |
Why not open rate? Open rate is unreliable — Apple Mail Privacy Protection and other tools inflate it artificially. Use reply rate as your north star.
How to diagnose your numbers
If your positive reply rate is below 5%, something is wrong. Work through this in order:
Technical setup — are your emails reaching the inbox? Check bounce rate and spam placement first.
ICP targeting — are you reaching the right people at the right time?
Copywriting — does your pain point resonate? Is your CTA compelling?

What to A/B test
Test one variable at a time. Use reply rate — not open rate — as your success metric.
Test these:
Pain points — which resonates most with your ICP?
Agitation angle — which framing creates the most urgency?
Value-based CTAs — which offer gets the most replies?
Email length — shorter vs. slightly longer
Don't bother testing:
Subject line tricks and clickbait — focus on relevance, not curiosity gaps
Sending time — minimal impact compared to copy quality
Open rates — unreliable metric, not worth optimizing for
How to track progress over time
Give each variation enough volume before drawing conclusions — at minimum 100 sends per variant, ideally 200+.
What to log for each campaign:
Pain point used
CTA type
Send volume
Positive reply rate
Meeting booking rate
Over time, patterns emerge: which pain points land, which CTAs convert, which segments respond best. That's your playbook.
Common questions
Q: How do I know if my email is working? Use the benchmark table above. If your positive reply rate is below 5%, check deliverability first, then targeting, then copy.
Q: My open rate is high but no one replies, what's wrong? Your subject line is doing its job but your email body isn't. The most common causes: leading with who you are instead of their pain, a vague problem statement, or a CTA that asks for a meeting before demonstrating value. See: How to write cold emails that get replies (PAS framework).
Q: What counts as a "positive" reply? Any reply that continues the conversation, interest, a question, asking for the resource you offered. Excludes out-of-office, unsubscribes, and "not interested" responses.
Q: Is a 2% reply rate ever acceptable? Only if your deal size is very large and your list is highly targeted (e.g., enterprise accounts). For most use cases, below 3% means something needs fixing.
Q: How long should I run a campaign before evaluating results? At minimum 2 weeks and 100+ sends. Less than that and you don't have enough data to draw conclusions.
Q: Should I track clicks? Clicks inside cold emails can trigger spam filters. Avoid tracked links in your first email, use plain text URLs or save links for follow-ups after you've gotten a reply.
Q: Should I mention competitors or alternatives in my email? Generally no, not in the first email. It complicates the message and can trigger objections before you've built any trust. Exception: if you're displacing a specific incumbent and that's your value prop:
If you're currently using [Competitor] for [use case], you're probablyfrustrated by [specific limitation]. We built [Solution] specificallyto solve that problem.
