One address for everything: hello@faxforagents.com. Copy it, or [open it in your mail client](mailto:hello@faxforagents.com). No form, no phone line, no chat widget.

## What to include

- For a job: the job id (`fax_...`) and the `X-Request-Id` or `correlation_id` from the error, if there was one. Never the document itself.
- For billing: the organization name and the payment reference from the receipt.
- For a number outside the launch countries: the country and what the number is for.
- For a security report: what you found and how to reproduce it. The same address is in [security.txt](https://faxforagents.com/.well-known/security.txt).

We answer within two working days. Replies come from the same address, signed by a person.
