TL;DR

Across the four vendor reports I pulled for this page (Woodpecker, Sendr, GMass, Clay), average cold email reply rates sit in the 1 to 5 percent band. Good campaigns run 5 to 10 percent. Great, tightly targeted ones sit above 10 percent. If a dashboard is showing you above 25 percent, audit the tracking pixel before you audit the copy.

How should you read this page?

Every number below links to the primary report it came from. Vendor reports carry their own selection bias, so we quote ranges rather than a single hero number. Where a report gives a median and an average, we use the median.

Bands to calibrate against. Above 25 percent usually indicates a tracking artefact.

When a "great" number is a lie

Reply rates above 25 percent sustained across hundreds of sends usually mean bots, catch-all inboxes replying with auto-responders, or tracking pixels counting opens as replies. Audit the actual thread contents before you celebrate.

What actually moves the number?

  1. Narrower ICP. Halving the target list roughly doubles the reply rate in most reports.
  2. Signal-anchored opener. Reference something the business did in the last 30 days.
  3. One clear ask. A single low-friction question outperforms a pitch plus a calendar link.
  4. Domain health. A cold domain with weak SPF and DKIM will not reach the inbox, so the reply rate cannot start.

Where do Milo users tend to sit on this ladder?

Milo runs signal-led prospecting with sends from the operator own Gmail or Outlook inbox and per-send approval. Users typically sit in the 5 to 12 percent band on local and SMB motions, in line with the "good to great" range in the ladder above. That is a function of narrow lists and copy that names the specific trigger, not a magic number in the product.

FAQ

What is a good reply rate for cold email in 2026?

Anything from 5 percent upward is good, above 10 percent is great, and sustained above 25 percent should be audited for artefacts.

Why do vendor reports disagree?

Different customer mixes and different definitions of reply. Some count auto-replies, some do not.

Are open rates a useful benchmark?

Not since Apple Mail Privacy Protection and Gmail image proxying. Track reply rate and positive reply rate instead.
