Set up the sender
Open Email fax → Send by email and check that sending is enabled for your account and that your sender/domain is approved. Verify domain ownership and publish the required SPF or DKIM records on the From domain: ownership verification alone does not authorize sending. Keep those records in place and check the displayed authentication status. Use your approved mailbox and supported attachments; PDF is the simplest first format.
Submit and inspect
- Attach the document privately.
- Address the message to the recipient fax number followed by @faxim.us using the displayed Address format in Send by email. Check every digit.
- Avoid document text in subject lines and support messages.
- Review Email fax activity and the exact outbound record in Sent.
Email to Fax is intake/processing; Fax to Email is notification. Accepted/queued/completed Email processing does not establish fax delivery or inbox placement. Rejected intake can reflect sender, attachment or address setup. Correct the specific observed issue, then reconcile any uncertain earlier effect before submitting again. Final notification evidence is independent of fax delivery; notification retry through the portal is unavailable.
Safe support details
For help, open Help in your signed-in Faximus account and copy support details. Provide only the page, request or fax reference if shown, approximate time/timezone and expected versus observed behavior. Do not share fax contents, medical details, passwords, verification codes, API keys, payment details, document links or raw logs. Support may need independent identity/account verification.
