You receive supplier outreach all the time. Here's how to read it: what a cold email's open rate means, how to tell a serious supplier from a mass blast, and the industry benchmarks to judge against.
Why this matters to buyers
As a buyer sourcing from suppliers, you get cold emails every week. Most are mass blasts. A few are genuine outreach from a factory that actually makes your product. Learning to tell them apart saves you time and gets you to the real suppliers faster. This page gives you the benchmarks and the signals.
Key benchmarks
Cold email is how most suppliers reach out to a new buyer. The unique open rate is the share of recipients who actually opened the email. It's the first filter on whether outreach is worth your attention:
The deeper signal is reads per person and repeat opens. An interested buyer reads an email more than once, and may come back to it. A high repeat-open rate on outreach means the supplier's message earned a second look — a real-intent signal, not a misclick.
Most cold email reports track opens and clicks — never forwards. But for a buyer, a forwarded email is the clearest signal of all: someone received it, judged it worth sharing, and passed it along the decision chain. That's far higher-confidence interest than an open, which can be a misclick or curiosity.
When a supplier's outreach gets forwarded to colleagues, it means the content resonated with a real procurement need. It's a mark of serious, relevant outreach rather than a mass blast.
A useful lesson from cold email data: the same send channel, with different message strategies, produces wildly different results. A well-targeted, buyer-personalized message can outperform a broad, generic one by 40+ percentage points. The takeaway for you as a buyer: a supplier who sends a message referencing your actual product and need is signaling genuine intent to work with you — worth engaging. A generic blast is not.
You don't need to become a cold email analyst. But knowing the benchmarks helps you triage the outreach you receive:
When you source through TokoAI, you don't triage cold emails at all. We find and verify suppliers who fit your request, and have them respond through our channel — so the outreach you see is already screened.

Industry benchmark sources
Open-rate baselines from major 2025 cold email industry reports (Woodpecker, GMass, Mailshake, Instantly). Manufacturing B2B unique open rate ~20-22%, repeat open rate ~10%. These are third-party industry averages, not a single vendor's claim.
