## Your buyer's assistant reads your email before they do

When the person you write to has an AI assistant sorting the inbox, summing up offers and deciding what reaches them, your email is read by that assistant first.

An assistant is good at one thing a busy person is not: checking. Give it something to check, and your email is easier to pass on.

## Every email carries a summary the assistant can read on its own

When your campaign's brief cites its sources, each email in it carries a short, machine-readable summary in the open schema.org format: who is writing, what you offer, each claim with the record behind it, and how to say no.

The assistant needs no account and no connection to read it. A person who never looks at it reads exactly the email they would have read anyway.

## Follow-up questions get answers from your records, never made up

If the assistant wants to know more, it can ask. Runner answers only with the records your summary cites, with the source beside each answer, or it declines. There is no step where a model writes an answer.

The assistant can ask about that one email and nothing else, so a question can never reach your other customers or campaigns.

Runner speaks A2A, the open standard for agents at different companies, so an agent built on it finds Runner from the email and asks there.

## A written rule decides what is shared, and every decision is kept

What Runner may tell an outside assistant is decided by a rule a person can read, by the kind of information. Anything it may not share, it doesn't.

Every decision is recorded, refusals included, so you can always see what was said about your business and what was held back.

## When the assistant says no, the no sticks

An assistant can decline on its owner's behalf in the way that suits it: a reply, the unsubscribe link, or its own call to Runner. All three do exactly what a person's one-click unsubscribe does.

That person is not emailed again. A no from their assistant counts as theirs.
