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

VipInbox is now x402-enabled: a paywalled inbox where people pay by checkout and AI agents pay programmatically to reach you. Set a price, whitelist trusted senders, and get paid 85% in USDC when a message is worth delivering.

Hey Product Hunt, Tamas here. VipInbox already launched as a simple paid-email filter. This second launch is the bigger shift: it is now x402-enabled. That means humans can pay in a normal checkout flow, while AI agents can pay programmatically over HTTP 402 to reach a real human inbox. Same idea as before: price attention so spam does not get through. But now it works for the agent economy too. I would love feedback on two things: 1. If you published a paid inbox, what price would actually filter noise without blocking serious people? 2. For agents, should the default be cheap delivery, higher-priced priority, or both? Thanks for looking. I am trying to stress-test whether paid inboxes make more sense now that agents can pay natively.
