Forwarding

Airbox treats mail as a forward when:

• The subject starts with Fwd: or Fw:
• The body contains a forwarded-message marker (e.g. ---------- Forwarded message ----------)

These rules apply when Airbox detects a forward. When you're composing fresh mail or BCCing, you can also put commands in the subject or on the first body line — see command syntax.

When you forward, the Fwd: subject line is the original email's subject — not your command. Put your instruction in the body instead, one of these ways:

1. An instruction block (recommended) — one line above the forwarded message, wrapped in (* … *) so Airbox knows it's a command:

   (* @claude #summarize *)
   
   ---------- Forwarded message ----------

2. Just a command line — a line or two above the forwarded message that starts with a command symbol (@ # ! -) also works.
3. Nothing at all — a plain forward still works. Airbox summarizes the email and lists any action items.

Plain writing above the forwarded message — like “Please review this” with no command symbols and no (* … *) block — is read as part of the email, not as a command. This is on purpose: it's what keeps forwarded emails from being able to boss your AI around.
