Cold email benchmarks, 2026: every number that matters

Every number below is one we operate against, drawn from 4M+ sends for 40+ B2B companies. Each links to the post that explains it. Bookmark this page; argue with any line of it by email.

Reply performance

• 1 interested reply per 200–350 contacts reached. Our campaign target once the message is dialed in.
• 1 per 800–1,000+. The industry's untested-message baseline, which is where one-template blasting lives.
• 52%–83.47% positive-reply share across angles on a live board, same product, same weeks. The spread is the message.
• What counts as interested: a real human writing back with intent. Opens, clicks and out-of-office all miss the bar. Full methodology for every figure here.

Conversion

• 25–40% of interested replies become meetings, with fast follow-up doing most of that work.
• Response speed: same day, ideally within hours. An interested reply cools measurably in an afternoon.

Volume and infrastructure

• 30 cold sends per inbox per day, after ramp, inside a 20 to 40 band. Scale comes from more inboxes, never louder ones.
• 2–3 inboxes per sending domain, secondary domains only, primary never touches cold email.
• 4–6 weeks of warmup before meaningful volume, on a schedule nothing legitimate can compress.
• 0 links, pixels or attachments in a first cold email.
• Bounce rate under 2%, which verification buys before a single send.

Cold email reply rates hold up because of infrastructure, not luck: separate sending domains, warmup on a schedule, reputation watched daily. How the sending side is engineered.

Market and timeline

• 10,000+ reachable contacts to test messaging properly; below that, precision ABM beats volume.
• 10–15 angles raced per market. Fewer teaches too little; more starves each angle of volume. How angles get written.
• 2–4 weeks from kickoff to campaigns sending; first replies within days of first sends; the winning message by week 8.

Before any of these numbers apply, the infrastructure has to be right: see the cold email deliverability checklist.

Money

• $3,000 to $10,000 per month, in US dollars, is the honest retainer range for a real system in 2026; $200–$800 per held meeting on pay-per-meeting deals (what drives the range); a US SDR runs about $121,000 fully loaded, from an $85,000 median on-target earnings plus employer benefit costs (sources and the arithmetic). Judge any of them on cost per interested reply.

Figures last verified September 21, 2026. Prices are US dollars. The retainer range and what moves it are set out on how much a cold email agency costs.

One real month, for scale
