Auto-draft replies to every email

The short answer

To auto-draft replies, auto-forward incoming mail to an Airbox inbox set up for drafting. Your own AI reads each message and emails back a ready-to-send draft reply — automatically, for every message — so answering is a quick review-and-send instead of a blank page. Importantly, Airbox drafts; it never auto-sends to a stranger on its own, so a rogue or injected email can't fire off a reply in your name.

Auto-draft, not auto-send

An AI that silently auto-replies to anyone is a liability — a single prompt-injection email could speak for you. Airbox deliberately stops at the draft: it does the writing automatically, you do the sending. That's the safe version of an autoresponder.

How to set it up

  1. Create a free Airbox address and connect your AI provider key.
  2. Add a Context doc with your tone, plus a default instruction like “draft a reply.”
  3. Auto-forward the mail you want drafted (e.g. a label or a sender) to that address.

Example default instruction

Subject: Fwd: (incoming mail)

(* @chatgpt draft a concise reply in my voice; if it needs info I don't have, list the open questions instead *)

---------- Forwarded message ----------
...the email you forwarded...

Good for

  • High-volume inboxes where every reply starts from a draft
  • Support or sales queues that need fast, consistent first drafts
  • Anyone who hates the blank reply box

Frequently asked questions

Does Airbox send emails to other people for me?
By design, Airbox emails the result back to you to review and send — it never sends to arbitrary recipients on its own, so untrusted email content can't trick it into emailing a stranger. It can reply in an existing thread when you ask, and it can email you a clean copy, but you stay in control of anything that goes to a third party.
Can it ever send automatically?
Not to third parties. The conversational reply returns to you, and an optional tool can email a clean copy to you, the verified owner. Sending to an external recipient always stays a deliberate action you take.
Do I have to forward each email by hand?
No. Forward or BCC manually when you want, or set an auto-forwarding rule in Gmail, Outlook, or Apple Mail so matching mail reaches your Airbox address automatically and runs through your AI with no extra steps.
How much does it cost?
Airbox has a free plan to get started. You bring your own AI provider API key, so you pay the provider directly for the tokens you use — there is no AI markup from Airbox.
