Cold email benchmarks for 2026: open, reply, and conversion rates
Everyone wants to know if their numbers are good. The honest answer is "it depends" — but there are ranges worth knowing, and a way to read your results that beats comparing yourself to a stranger's screenshot on LinkedIn.

"Are my numbers good?" is the most common question in outbound and the most frustrating to answer, because the honest reply is: compared to what? A 2% reply rate is a disaster for one campaign and a win for another. Still, you deserve better than a shrug — so here are the ranges worth knowing, and a healthier way to think about your own results than measuring them against a stranger's screenshot.
The numbers people actually ask about
Across B2B cold email, here's roughly where things land when the fundamentals are in place. Treat these as rules of thumb, not laws — your mileage will vary, sometimes a lot.
- Open rate: 40–60%. A rough signal at best, and — see below — the least trustworthy number you have.
- Reply rate: 1–5%. That's the healthy band. Above 5% is strong. Below 1% means something upstream is broken.
- Positive reply rate: ~10–30% of replies. Of the people who respond, that's roughly how many are interested rather than "no thanks."
- Meetings: about one per few hundred well-targeted sends. The exact figure swings hard with your market and offer.
Why open rate is the worst metric you have
Open tracking works by loading a tiny invisible image; when it loads, the tool counts an open. Apple's Mail Privacy Protection — on by default for a huge share of inboxes — pre-loads that image whether or not a human ever looked. So a large chunk of your "opens" are machines, not people.
Which means an inflated open rate can hide a deliverability problem, and a "good" open rate can be close to meaningless. Don't optimize for it. Don't report it to your boss as if it's truth. At best it's a fuzzy directional signal.
If you're going to obsess over one number, make it reply rate. People can't fake a reply, and a reply is the first thing in outbound that actually correlates with revenue.
Reply rate is the signal that matters
A reply means a real person read enough to respond. That's why it's the number we'd stake a campaign on. The 1–5% band is wide on purpose — where you land inside it depends almost entirely on two things: did the email reach the inbox, and was it sent to the right person with something relevant to say. Get a reply rate under 1% and resist the urge to rewrite the copy first. Nine times out of ten the problem is deliverability or targeting, not your sentences.
Positive reply rate tells you about fit
Raw reply rate includes the no's, the wrong-person's, and the occasional "please remove me." The more telling number is what share of replies are actually positive — curious, asking for more, booking time. A high reply rate made entirely of polite declines means your message provokes but your targeting or offer is off. A lower reply rate that's mostly positive means you've found fit and should pour fuel on it.
From replies to meetings to revenue
Stack the funnel and it's sobering: a few percent reply, a fraction of those positive, a fraction of those becoming meetings. That's why volume and precision both matter — and why one good email to the right list beats a thousand to the wrong one. We've watched this play out across 38,500+ emails: the campaigns that move are the focused ones, not the loud ones.
Benchmarks are a trap — do this instead
Here's the part no benchmark post wants to admit: external numbers are nearly useless for judging your campaign, because the variables — industry, list quality, offer, sender reputation, timing — swamp any average. Someone's 8% reply rate might be a tiny, warm-ish list in a niche where you have none.
So stop comparing outward. Build your own baseline, then change one thing at a time.
- Establish a baseline before you optimize — you can't improve a number you haven't measured.
- Change one variable per test, so you actually know what caused the move.
- Weight positive replies over raw replies, and replies over opens.
- Read a bad number top-down: inbox first, list second, message third.
Good benchmarks aren't a scoreboard to beat. They're a sanity check — a way to know you're in the right neighborhood — before the real work of beating your own numbers. If your replies are stuck below that 1% floor, start with deliverability; it's usually the culprit. If they're landing but not converting, it's probably one of these four things.
