One thread per customer, across every channel.

The market has already de-coupled AI from the seat and turned it into a meter: $0.05 per conversation at one vendor, $0.99 per outcome at another, and one large vendor that does not publish its rate at all. A meter you cannot forecast is a bill you cannot approve. Bookesto publishes every rate it charges, and the inbox itself is included in the seat.

Anyone can send email from an address. Where a channel supports cryptographic identity verification, Bookesto will use it, and what an unverified contact can see will be deliberately narrower than what a verified one can: an unverified person is told that a booking exists and when, and nothing about payments, deposit amounts or history. That rule is enforced in our own API rather than in the inbox interface, because the interface is not the security boundary.

An AI agent answering customers needs three things before it can exist: a commercial model API with a signed data-processing agreement, an approved monthly budget cap, and a disclosure at the first message of every conversation, which European law has required since 2 August 2026. None of the first two is approved. Until they are, the inbox is a human inbox, the price does not depend on the AI shipping, and this page will not pretend otherwise.
