Warm-signal high-volume email (website visitor identity resolution)
Identify anonymous website visitors using reverse IP or identity resolution tools, then email them at scale while they are still warm from browsing your site, converting at 10x the rate of traditional cold email.
Why this can grow a startup
Recipients have already shown intent by visiting your website, so they are far more receptive than a purely cold contact. Because the email arrives while the prospect is still in research mode, it feels timely rather than intrusive. High volume is sustainable because deliverability stays clean when targeting engaged visitors rather than scraped lists. The method bridges the gap between expensive retargeting ads and ineffective cold outreach, delivering warm leads at cold email cost.
Company example
RB2B (Adam Robinson) — sends 200K+ emails monthly to identified website visitors, rarely hitting spam, and reports 10x conversion rates versus traditional cold email; the approach fueled RB2B's growth to $6M ARR in 18 months.

When to use it
Use this when Ads, Email is relevant to 0-100, 100-1K and you can run a bounded test with a paid budget.
When not to use it
Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
