Write follow-up emails with AI

The short answer

To write a follow-up email with AI, forward the original thread to your Airbox address and ask for a follow-up. Airbox reads the context, then emails back a short, polite nudge that references what was said and makes the next step easy — ready for you to review and send. No more staring at a blank reply box.

How to do it

  1. Get a free Airbox address and connect your AI provider key.
  2. Forward the thread you're chasing.
  3. Ask for the nudge — “draft a friendly follow-up that asks for a decision by Friday” — and send.

Example

Subject: Fwd: Proposal — following up

(* @claude draft a brief, warm follow-up; reference the proposal and propose two times to talk *)

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

Apply the “Follow-up nudge drafts” recipe to standardize tone across an inbox.

Good for

  • Sales and proposal follow-ups
  • Chasing approvals or answers without nagging
  • Re-engaging a thread that went quiet
  • Consistent tone across a whole pipeline

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.
Does it know what was already said?
Yes. Forward the full thread and Airbox uses the prior messages as context, so the follow-up references specifics instead of sounding generic.
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.
Is it safe to point Airbox at my real email?
Yes — that's exactly what Airbox is designed for. Airbox only acts on mail from senders you allow, and it only treats the subject and first body line (or a (* … *) block) as instructions. Everything else in a forwarded email is quarantined as untrusted content and never obeyed for your own security and privacy. Your API keys stay fully encrypted.
