Source: Instantly's 2026 Cold Email Benchmark Report, platform data from 1 January to 18 December 2025. Reply rate = all replies (including follow-up responses) divided by total emails sent.
The same report found 58% of replies came from the first email in a sequence and 42% from follow ups, that Tuesday and Wednesday saw the highest reply rates, and that the best campaigns kept emails under 80 words.
How to calculate your cold email response rate
Reply rate = replies ÷ emails sent × 100. Example: 45 replies from 1,500 emails is 3%.
Decide up front whether you count auto-replies and out-of-office messages, and whether you divide by emails or by contacts. Per contact, a 4-step sequence to 500 people with 45 replies is 9%, while per email it is about 2.3%. Our reply rate calculator does both.
What improves reply rates
- Tighter targeting. A smaller list that clearly has the problem beats a big generic one.
- Shorter emails. The benchmark's best campaigns stayed under 80 words.
- Follow ups. With 42% of replies coming after the first email, a sequence of 3 to 4 follow ups matters.
- Deliverability. Authenticate domains and warm mailboxes; see how to improve email deliverability.
