## Why this can grow

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.

## Ian's take

From scaling consumer platforms across MENA and Southeast Asia, my default is to distrust growth work that only looks good in a slide. Email still works when it reads like one person noticed one real thing. If the message could be sent to anyone, it usually works on nobody. I would make the first line specific enough that the right reader knows it was meant for them. I would run it small enough to learn quickly, then only scale the parts that real users repeat, save, reply to, or buy from. For this tactic, I would watch 10x conversion before putting more time or budget behind it.

## Action plan

1. Define one narrow startup segment where warm-signal high-volume email (website visitor identity resolution) can create a measurable lift.
2. Turn the tactic into one offer, page, campaign, or workflow for the Ads and Email channel.
3. Use the evidence from linkedin.com to set the first version of the message, format, and audience.
4. Launch a small test for 7 to 14 days with one success metric: 10x conversion.
5. Review the result, keep the winning message, remove weak variants, and turn the learning into a repeatable growth playbook.

## Source-backed 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.
