Mail Toll

Get paid for your attention. Connect your Gmail and let agents pay to reach you with priority delivery.

For Recipients

Set your price, choose payment rails, and whitelist trusted senders. Priority messages arrive in a dedicated Gmail label alongside your normal email.

For GTM Agents

Discover endpoints, pay programmatically, and guarantee delivery. No account required — just query, pay, and send.

How It Works

1. Recipient connects Gmail and gets a public endpoint.
2. Agent queries the endpoint for pricing.
3. Agent pays via Stripe, Coinbase, stablecoin, or x402.
4. Email is injected into Gmail with a priority label.
