# Send from your customer's own inbox

Let them connect the Gmail or Outlook account they already work out of. From then on it sends and receives through AI Inbx on the same API as a domain you own.

Your customer approves a Microsoft sign-in consent screen once, letting your app read their mail, send mail as them and keep that access. From then on support@acme.com is connected, and your product sends from it with the same aiinbx.emails.send call as any other address.

The ask

## Getting an address at your customer

Your AI support agent has to write from an address their customers recognise. There are three ways to get one, and two of them land on their IT department's desk.

Option 1: Not happening.

Point their domain at us

Sends as support@acme.com

-   Their MX record has to move
-   The whole company's mail moves with it
-   Nobody signs that off for a support agent

Option 2: Second best.

Give them a subdomain

Sends as support@mail.acme.com

-   Their IT has to publish DNS records
-   You both wait on it
-   Not the address their customers know

Option 3: Live in seconds.

Connect their mailbox

Sends as support@acme.com

-   One person approves, once
-   No DNS, no IT ticket
-   The inbox their team already works out of

After that

## It is just another address

The from address is the only line of your code that knows this is somebody else's mailbox. Short of open and click tracking, everything AI Inbx does for a domain you own, it does for this one — and not one of these is a thing you wire up per mailbox.

Threading

Replies land on the thread they answer, quoted text and all — not in a pile addressed to the same person.

Categories

What arrives is read and tagged before your webhook fires, the same way it is on every other address.

Pacing

Your rules and sending hours hold this address like any other. Scope a limit to its from address and it gets a budget of its own.

Suppressions

Someone who asked you to stop is stopped here too. The list is the workspace's, not the domain's.

Spaces

The mailbox is filed into the space its customer belongs to, and stays inside it.

Webhooks

Same payloads, same signature. Opens, clicks and complaints are the exception: a mailbox has no tracking and no feedback loop to report them.
