How to email Mistral
The short version
To email Mistral, sign up for Airbox to get a private email address, connect your Mistral API key once, then forward or BCC any email to that address. Airbox passes the message to Mistral and emails the answer back into your inbox — no app, no copy-paste, no code.
What you need
- A free Airbox account
- A Mistral API key from the Mistral AI Console — it stays encrypted
1. Get your Airbox address
Create a free account and open the dashboard to make an inbox. You get an unguessable address like c4f8xxxx@airbox.fyi. Save it as a contact or BCC it on outgoing mail. See the quick start for the full walkthrough.
2. Connect Mistral
Airbox uses your own Mistral API key, so you stay in control of the model and your usage. Mistral also offers EU hosting if that matters to you. You paste the key in just once.
- Open the Mistral AI Console (console.mistral.ai/api-keys) and create an API key.
- In your Airbox dashboard, go to Connections → + AI & LLM provider → Mistral and paste the key.
- Set it as your inbox default and Save. Target it with @mistral in your emails.

3. Send your first email
Forward or BCC any email to your Airbox address. To ask for something specific, put a short instruction on the trusted surface — the subject, the first body line, or a (* … *) block at the top:
Subject: Fwd: Q3 planning thread (* @mistral summarize this and list the action items *) ---------- Forwarded message ---------- ...the email you forwarded...
A plain send or forward with no instruction works too — Airbox summarizes the email and lists action items by default.
Anything else in a forwarded email is treated as content to read, never as a command. More in the command syntax and forwarding guides.

Frequently asked questions
- Do I need a paid Mistral account?
- You need a Mistral API key from console.mistral.ai. API usage is billed to your Mistral account, separate from any consumer Le Chat subscription — add billing or credits if the console asks before first use.
- Which Mistral model does it use?
- By default mistral-large-latest. You can override the model per inbox or per email if you want a smaller or faster one.
- 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.
