Fight spam with capitalism
Put a price on your inbox.
OnlySeriousEmail gives you a public address with a toll gate. People you trust reach you instantly, free. Strangers pay a toll — at a price you set — to prove they're serious. And spam, which never pays for anything, quietly disappears.
Free for recipients, forever. No app to install, no inbox to migrate — your mail still lands where it always has.
Three moving parts. One quiet inbox.
Publish your address
Claim [email protected] and put it everywhere — bio, website,
conference badge, the side of a bus. Your real inbox stays private.
Strangers pay the toll
Unknown senders get a polite, one-time request: confirm delivery for the fee you chose when you claimed the address. Serious people pay it without blinking. Bots, blasters, and bulk-CC artists never do.
Your circle rides free
A sender who confirms once becomes trusted, and you can whitelist anyone yourself. Trusted mail is forwarded instantly — no fee, no friction, forever.
Your attention is the most over-drafted account you own. Start charging.
Made for people the whole world can email
Creators & influencers
A velvet rope for your DMs
Post one address to a million followers without fear. Sponsors and collabs clear the gate in seconds; the "quick favor" crowd stays outside. The toll isn't the point — the filter is.
Founders & executives
Cold outreach, warmed up
Every pitch that reaches you cost its sender something, which means it was worth something to them. Sequence blasts and scraped-list spam don't pay tolls. Real opportunities do.
The privately public
Reachable, not exposed
Journalists, doctors, professors, landlords — anyone whose address ends up on the open web. Stay contactable by the world without handing the world your real inbox.
Asked to confirm delivery?
The person you wrote to routes their mail through OnlySeriousEmail. Your message is safe and untouched — confirm delivery and it lands immediately, often with a permanent pass for future mail. If delivery fails, you're automatically refunded.
Put a seal on it.
Claim your protected address in about a minute. Free for you — the spammers pick up the tab.
