What's a Good Cold Email Open Rate? The Honest Answer
For B2B cold outbound, 15–25% is a realistic average and 25–40% is considered strong, according to SalesHive's 2025 benchmarks. A separate 2024 B2B cold email study (as reported by SalesHive) found an average of 27.7%. Focus Digital, a cold-email agency whose benchmarks reflect their managed campaigns, puts the cross-industry average closer to 39%. These two numbers aren't contradicting each other so much as measuring different things — and that gap is something every SDR needs to understand before benchmarking their own performance.
The short version: if your cold outbound open rates are in the high teens or low 20s, you're not broken — that's where most clean, well-targeted cold campaigns actually land.
Why the Benchmarks Disagree — and Why That Matters
The spread between sources isn't noise. There are two structural reasons the numbers look so different depending on where you look:
- Apple Mail Privacy Protection (MPP) inflation. Apple MPP preloads email content and pixels before a user ever reads the message, which registers as an "open" even when no human opened anything. SalesHive notes that one large-scale analysis showed total open rates rising from roughly 22.6% to 40.5% within six months of Apple's change — nearly doubling without senders getting any better. If your audience skews toward Apple Mail users, your open rates are likely inflated. Treat them as directional, not precise.
- Cold outbound vs. opt-in marketing email are completely different motions. HubSpot reports a 42.35% average open rate across all email as of 2025 — but that figure covers opt-in marketing and newsletter email across all industries. It is not a cold outbound benchmark, and comparing your SDR sequences to it will only make you feel worse about numbers that are actually fine.
The practical upshot: always ask what email motion and what audience mix a benchmark is measuring before you use it to grade your own campaigns.
Benchmarks by Source (Cold Outbound Only)
SalesHive (vendor source — cold email/SDR outsourcing)
Note: SalesHive is a cold email and SDR outsourcing vendor with a commercial interest in this topic. Their benchmarks are useful directional guidance but should be read with that context in mind.
- Cold outbound to net-new prospects: 15–25% average; 25–40% strong (with clean data and warmed domains)
- Warm sales sequences (inbound leads, past opportunities): mid-20s to high-30s
- A 2024 B2B cold email study (as reported by SalesHive, not SalesHive's own data) found an average open rate of 27.7% with a 5.1% reply rate
- Broader industry data cited by SalesHive puts average open rates around 21.5% across industries, with B2B campaigns slightly lower at about 19.2%; a separate benchmark reported a median B2B open rate of 22.8%
Focus Digital (vendor source — cold email agency)
Note: Focus Digital is a cold-email agency whose benchmark data reflects their own managed campaigns. Methodology is self-reported without independent audit, so treat these numbers as indicative rather than neutral industry-wide figures.
- Cross-industry average for well-executed B2B cold email campaigns: ~39%
- This figure likely reflects MPP inflation and the specific campaign quality of their managed client base
Woodpecker (platform data — 20M+ cold emails sent)
- Woodpecker's data focuses primarily on reply rates: campaigns using advanced personalization (custom snippets beyond first name and company) achieved a 17% reply rate vs. 7% reply rate for non-personalized emails
- List quality combined with personalization are cited as the two biggest drivers of reply performance
Open Rates by Industry (Focus Digital, 2025)
Industry context matters more than most people expect. Focus Digital's data shows a wide range across B2B sectors:
- SaaS: 25.71%
- IT Services: 27.35%
- Cybersecurity: 27.32%
- Financial Services: 27.87%
- Consulting Services: 28.93%
- Legal Services: 31.45%
- Human Resources and Recruiting: 30.57%
- Biotechnology: 34.83%
- Commercial Real Estate: 38.51%
- Investment Firms: 45.47%
- Oil and Gas Services: 44.99%
- Energy Management Systems: 46.31%
Sectors like energy management and investment firms (~45–46%) run roughly 70% higher than SaaS and IT services (~25–27%) — not quite "double," but a meaningful gap that's worth knowing if you're switching verticals or building industry-specific sequences.
If your industry average is below 30%, Focus Digital recommends focusing on targeting and personalization rather than email frequency.
Don't Optimize Opens in Isolation
Open rates are a diagnostic signal, not a scoreboard. SalesHive makes this point directly: when opens suddenly drop, you want to catch it before reply volume and pipeline quietly follow. But opens alone won't tell you if your messaging converts.
For reply rates, the data is more encouraging than many assume. The 2024 B2B cold email study cited by SalesHive found a 5.1% reply rate alongside that 27.7% open rate. Woodpecker's platform data shows 7% reply rates for standard campaigns and 17% for heavily personalized ones. If you've been reading benchmarks that cite 0.5–2% reply rates, those figures don't appear in the primary sources — the actual data points considerably higher.
The metric stack worth tracking: open rate (for deliverability and list health), reply rate (for message quality), and meetings booked per 100 opens (for sequence effectiveness). Open rates catch problems early. Reply rates and meetings tell you if you're actually winning.
