Get paid from AI spam.
The robots want your attention. Charge them for it.
Unknown senders, meeting your price.
The toll booth, in four moves.
Connect
Connect Gmail or Mailpipe. One sign-in. MailToll builds your whitelist from your history, sets up everything, and your toll goes live. About sixty seconds, none of them spent on settings.
Quarantine
Every unknown sender is held at the gate and quoted your price. Humans get a checkout link. Machines get a payment challenge they can settle in seconds.
Collect
Paid mail lands in your inbox wearing a Paid badge. If you never open it, the sender is refunded after 7 days. Attention stays honest.
Reply, or don't
Reply once and that sender is whitelisted free forever. Ignore the rest and enjoy the weekly digest: you made $34 and blocked 1,220 emails.
Sending spam costs nothing. That was the whole problem.
A bot can hit a million inboxes for lunch money. Your attention was the last free resource on the internet. MailToll changes the price.
Server time and a purchased list. The recipients absorb the rest of the cost.
At the default $5 toll. Paid up front to the people being pitched.
Suddenly, volume is their problem.
The robots carry budgets now.
Agentic senders ship with spend limits. Their builders knew this was coming. An outreach agent that can't pay a toll is an outreach agent that doesn't deliver.
The well-built ones pay before they knock. Every inbox posts its toll at a public price endpoint, mailtoll.xyz/p/yourname. An agent checks the price, prepays it, and gets a single-use delivery token. Mail sent with the token lands with the Paid badge already on. No challenge, no round trip.
The rest get a 402 at the gate. MailToll answers in their native tongue, x402 style: a machine-readable price they can settle in seconds. No human in the loop. Except the one collecting.
# anyone can read the toll before sending GET mailtoll.xyz/p/thom { "protocol": "mailtoll.v1", "price": { "amount": "5.00", "currency": "USD" }, "pay_to": "mailtoll:inbox_7f2c91" } # prepay it, take a single-use token POST mailtoll.xyz/v1/prepay { "paid": "5.00", "token": "dtk_9c41aa02", "single_use": true } # send once, token attached MailToll-Token: dtk_9c41aa02 → delivered, Paid badge on arrival, no challenge
The prepay path, as a well-built bot sees it. The lazy ones get a 402 challenge at the gate instead.
You know it landed.
Placement is what you paid for; the open is what captures the payment. Unopened for 7 days, it refunds itself.
The weekly digest reads like a paystub.
Fair questions.
What happens to receipts and password resets?+
Nothing. The first scan learns your transactional mail: receipts, password resets, shipping updates, school, the bank. It keeps flowing free. No paywall, no drama.
Is reading guaranteed?+
No, and we won't pretend otherwise. Payment guarantees placement in your inbox, not your attention. If a paid message sits unopened for 7 days, the sender is automatically refunded.
Will my friends get charged?+
Anyone you've ever replied to is whitelisted from day one, and you can add anyone by hand. If a new human pays once and you reply, they're free forever.
Who sets the price, and who keeps the money?+
You set it. The default is $5 for a first contact. Charge more, charge less, or route it all to a charity you pick. MailToll keeps 10 percent of paid deliveries. Free mail stays free.
What does it work with?+
Gmail and Mailpipe today. Your address stays the same, and senders notice nothing until they hit the gate.
