Open rate measures what percentage of your cold emails are actually opened by recipients. It's the top-of-funnel metric for cold outreach — without a high enough open rate, even perfect copy can't generate replies. Open rates are increasingly tricky to measure accurately as Apple Mail Privacy Protection and other tools inflate tracked opens.
Summary
Good cold email open rate for B2B outbound is 35–55%. Above 60% suggests an exceptionally targeted list; below 20% typically indicates deliverability problems or subject lines that aren't compelling.

Cactus insight: We've seen open rates as high as 72% on tightly targeted account-based campaigns where recipients had prior brand touchpoints — and as low as 8% on purchased list blasts. The gap isn't subject line cleverness; it's list quality and deliverability infrastructure. Build the sending infrastructure before worrying about creative.
