The current benchmark
Across B2B SaaS sequences targeting C-suite buyers in 2026:
Open rate: 8-15% (heavily depressed from inbox AI filtering)
Reply rate: 0.3-1.5%
Meeting acceptance rate: 0.1-0.5%
These numbers are roughly 5-10x lower than 2018 benchmarks. They are not improving. AI-personalization tools have not moved the needle because the underlying problem isn't personalization quality.
Why C-level is uniquely broken
Lower altitudes (Director, Manager, IC) still produce reasonable cold reply rates — 2-5% depending on category. The collapse is concentrated at VP+ because:
C-suite inboxes get 10-20x the cold volume of lower-altitude inboxes.
C-suite buyers explicitly use peer-only signal as a triage mechanism.
Their EAs aggressively filter (or their inbox AI does the equivalent).
Their time cost of triage is much higher, so the decision rule becomes 'ignore unknown senders by default.'
What looks like high cold reply rate but isn't
If your cold sequences to C-level are landing above 1%, common explanations:
You're measuring reply rate including auto-replies and 'unsubscribe' responses.
You're targeting personal email addresses, not work inboxes.
Your 'cold' isn't actually cold — there's a peer reference, prior interaction, or event context you're not counting.
You're early in a sequence and a few replies are concentrated in the first 100 sends; the rate falls quickly.
What works instead at C-level
Warm intros (30-50% meeting acceptance). Field events and dinners (10-25% follow-up rate). Inbound from substantive content (variable but compounds). Cold outreach is the worst channel option for C-level in 2026 — not because the technique is bad, but because the category has structurally moved.
