Belkins divides unique replies by every email sent to cold, net-new contacts and gets 0.45%.
About six months and 19,326 messages later, SaaStr reported a 6.67% response rate: roughly 1,289 responses. A 7.5-million-email benchmark from Belkins puts the average cold email reply rate at 0.45%. Its 2026 study (published June 2026) is the most transparent cold email dataset I found.
