SaaS, agency, and recruiting cold email are three of the most common use cases on this site, and they produce meaningfully different numbers at every stage of the funnel — for reasons that have more to do with the recipient's situation than with copywriting quality.
| Metric | SaaS-to-SaaS | Agency-to-SMB | Recruiting (non-tech) |
|---|---|---|---|
| Open rate | ~46% | 28–34% (marketing/advertising range) | Not separately benchmarked; tracks close to real estate/services, ~35–40% |
| Reply rate | 2–4% | ~4.2% | ~7.2% |
| Meeting-booked rate | 0.5–1.5% | 1.0–2.5% (professional services range) | 1.0–2.5% (staffing range) |
The most counterintuitive line in this table is open rate: SaaS posts the highest open rate of the three by a wide margin, and still ends up with the lowest reply and meeting-booked rate. Open rate and downstream conversion are not the same signal, and this comparison is one of the clearest illustrations of why — see the open rate benchmarks guide for the deeper reasoning.
SaaS buyers are professionally trained to open and skim vendor emails — it's part of the job for anyone evaluating tools — which explains the high open rate. But that same buyer is usually mid-evaluation-cycle already, fielding comparable outreach from several competing vendors, with no personal urgency forcing a reply either way. High familiarity with the format plus low urgency to respond is exactly the combination that produces a healthy open rate and a modest reply rate.
Recruiting outreach benefits from the single strongest driver of reply rate across every industry in this comparison set: the recipient has a direct, personal stake in the outcome. A candidate weighing whether to hear more about a role is deciding something that affects their own career, not evaluating a vendor on behalf of an employer — that distinction alone explains most of the gap between recruiting's ~7.2% reply rate and SaaS's 2-4%.
Agency-to-SMB outreach lands in the middle on every metric, which fits its position between the other two use cases: the recipient (typically a business owner or marketing lead) has more personal stake in the outcome than a SaaS evaluator buying on behalf of a team, but less than a recruiting candidate deciding about their own career. See the agency guide and the meeting-to-close rate guide for how this translates further down the funnel toward closed revenue.
Recruiting outreach consistently outperforms SaaS-to-SaaS outreach on reply rate (roughly 7.2% vs 2-4%) and meeting-booked rate, despite SaaS posting a much higher open rate (around 46% vs recruiting's mid-30s%). The recipient's personal stake in the outcome, not the open rate, is what drives the difference.
SaaS buyers are professionally accustomed to opening and skimming vendor emails as part of an evaluation process, which drives a high open rate. But they're usually comparing several vendors at once with no personal urgency to reply to any single one, which keeps reply rate comparatively low.
In the middle on nearly every metric — reply rate around 4.2%, meeting-booked rate in the 1.0-2.5% range. This fits the recipient's position between the other two use cases: more personal stake than a SaaS buyer evaluating on behalf of a team, less than a recruiting candidate deciding about their own career.
No — they're meant to explain why a given use case's numbers look the way they do, not to rank use cases against each other. Compare a SaaS campaign against SaaS benchmarks and a recruiting campaign against recruiting benchmarks, not across categories.
