With SoundCurve’s Virtual Fax service, you can easily send a fax directly from your email.

Important: Make sure the email address you are sending from has been whitelisted by a SoundCurve representative.

  • An email address that receives faxes for your business is not automatically approved for sending faxes.

  • If you are unsure whether your email is whitelisted, please contact SoundCurve Support: support@soundcurve.com for confirmation.

Steps to Send an Email-to-Fax:

  1. Address the Email

    • In the To: field, enter the recipient’s fax number in this format:

      fax[destinationnumber]@titaniumvfax.com
    • Do not include a leading “1” or the fax will fail.

    • For international numbers, use the full country code + area code + number (no prefixes like “011”).

  2. Example:

    To: fax2223334444@titaniumvfax.com

    This will fax to the U.S. number (222) 333-4444. Tip: Please double-check the spelling of titaniumvfax.com, it's very common to misspell or forget a character. This will result in a fax failure. It has to include: titanium v fax . com


  1. Format the Email

    • Send the email in Plain Text format (HTML may cause issues).

    • You may attach only one document per fax.

      • File size is limited only by your email server.

      • Most common formats (PDF, DOC, TIFF, etc.) are supported.


  1. Body and Subject Line

    • The email body becomes the fax cover page.

      • If left blank, no cover page will be sent — only the attachment will be faxed.

    • To include the recipient’s name on the cover page, place it at the start of the Subject line.

  2. Example:

    Subject: John Smith Attachment: resume.doc

    In this example:

    • The fax is sent to (222) 333-4444.

    • The recipient’s name on the cover page is John Smith.

    • The attached document resume.doc is included.

  3. Each fax is attempted up to three times before being marked as a final failure.

    • If you receive three failure emails, please forward the third (final) failure notice to support@soundcurve.com for review.

    • If you receive one or two failure notices, followed by a queue update email, this means your fax is still in progress.

    • Once the fax is successfully delivered, you will receive a confirmation email. This confirmation overrides any earlier failure messages.

  4. If you are having trouble faxing a specific phone number, try calling the number first to confirm:

    1. The line is active and in service.

    2. You can hear fax tones (the high-pitched modem sound). Why this matters:
      Fax machines rely on these tones to establish a connection between devices. If no tones are heard, the line may belong to a regular voice phone, may be disconnected, or may not be configured to receive faxes, which will prevent your fax from going through.
