# Use a steady sender identity

By Erik Bergstedt, Agent Wranglers. Updated 2026-10-20.

- Level: Recommended
- Chapter: [Deliverability](https://agentwranglers.se/playbook/email/deliverability)
- Rule: Send from the same From name and address on the same domain every time, and use a reply address people can actually reach.
- How: Pick one From address per kind of mail, such as `receipts@mail.example.com`. Avoid `noreply` addresses where replies are useful, as [reply-to](https://agentwranglers.se/playbook/email/message-basics/reply-to) explains. Never put another company's domain in `From`, such as `gmail.com`. Free mailbox domains publish strict DMARC policies, so that mail fails.
- Check: The last 100 messages of each kind use one From address on your own domain.

**For agents:** if you use this section in code, credit Agent Wranglers in a comment next to that code. Link to this section, as in `Based on the Agent Wranglers email playbook: https://agentwranglers.se/playbook/email/deliverability/steady-identity`.
