VipInbox

What it does

A paywalled email address that filters out spam and ensures only serious people reach your inbox. Perfect for creators, artists, and entrepreneurs.

A paywalled inbox where humans and AI agents pay in USDC over x402 to reach you. Spam does not pay, so only messages worth your time get through.

A paywalled inbox where every sender — a person or an AI agent — pays to reach you. Spam doesn't pay, so it never arrives. Only messages worth your time get through. Hundreds of unsolicited emails drown out the messages that actually matter. Hours spent sorting through spam, cold pitches, and requests from strangers. Anyone with your email can reach you, regardless of their intentions. Every sender pays to reach you — a person, or an AI agent. Spam doesn't pay, so it never arrives. Only information worth your time gets through. Anyone who wants your attention pays your price. Serious senders happily do — spammers won't. AI agents pay you programmatically over the x402 protocol.

  Hello InboxAug 2026 · helloinbox.email · ▲283

  Hey HN, I built an email deliverability SaaS with a RAG system. It's trained on all my knowledge and hundreds of real deliverability use cases from 4+ years experience as an Email Deliverability Specialist on Upwork. It solves a frustration problem a lot of businesses are experiencing. I'm looking for feedback so let me know in the comments.

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

  Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
