Cheapest hyper-personalised outbound infra (guide + stack)

Claude Sonnet 5 is out. So I'm open-sourcing the most cost-effective cold email system I could build.

100k hyper-personalised emails a month. Under $1k in tooling.

Everyone's calling Sonnet 5 a step down from the frontier models. They're missing the point.

You pick the right model for the right task. Cold email is not that deep. You don't need PhD-level AGI to plan and launch a campaign.

We tested 40+ tools to land on the highest quality for the lowest price. And it works: $477k in pipeline for one client.

The whole stack, the real costs, 6 frameworks to swipe. If you want it:

and I'll send it over :)
