Ask HN: Why do purchased B2B email lists still have such poor deliverability?

Sat, 02/07/2026 - 7:03pm

I’ve run into this multiple times and I’m honestly still confused. I’ve tested purchased B2B email lists (including ones sold as “verified”), and deliverability is often terrible — bounces, low engagement, the usual. Is the core problem outdated data, weak verification, catch-all domains, or something else? For people who’ve actually solved this, what approaches worked in practice?

Show HN: Kokki – A "Dual-Core" System Prompt to Reduce LLM Hallucinations

Sat, 02/07/2026 - 6:58pm

I built a system prompt architecture that forces LLMs (like Gemini 3.0 / Claude 4.5) to self-audit before responding.

It splits the model into two personas:

Agent: Generates the draft.

Auditor: Critiques the draft for logic errors and hallucinations.

The Code (Gist): [https://gist.github.com/ginsabo/9d99ee98068d904b214be9351f09...]

I also wrote a documentation book about the theory, but the Gist above is fully functional and free to use. I'd love to hear your feedback on this "User-Side Safety" approach.
