What's a good cold email reply rate in 2026?

For well-targeted, genuinely personalized B2B outreach: 5-10% replies, with 2-5% positive. Below 2% total replies means your targeting or relevance is broken — more volume will only burn the domain faster. The biggest lever isn't copy, it's research: sequences written from an actual prospect dossier (their stack, their hiring, their public statements) consistently double token-personalization ('Hi {first_name}') campaigns. Cap daily volume per domain, warm up new domains over weeks, and treat deliverability as a prerequisite, not an optimization.
