Frequenty Asked Questions: Recieving Faxes

How do I view received faxes?

Your fax document(s) will be delivered to you via email as attachments. They are sent to your email account or accounts.

By default, Windows opens TIF faxes as an image or with "Windows Picture and Fax Viewer". PDF attachments default to the free Adobe Reader. On MacOS the default viewer for both TIF and PDF is Preview.

What file format choices do I have when receiving faxes?

We currently deliver faxes to you in either .tif or .pdf format. By default, we deliver in .tif (or .tiff) format. Contact our support team if you want to change the format you receive faxes.

Can I receive faxes at multiple email addresses?

Yes! You can receive your faxes at up to 5 email addresses, at no additional charge. To make any changes or add emails, please contact our support team.

Do I need to download any faxing software?

No, there is no faxing software needed to use our service. Our system works with your existing email program, document and image readers, on Windows, MacOS, IOS, and Android.

Will Faxpipe send me junk faxes?

No, we will not send junk faxes or advertisement faxes to you. We do our best to keep your fax number private, and we do not share your information with third parties.

What should I do if I receive a junk fax?

While most of our users never receive junk faxes, we cannot guarantee that you will never receive one. We do, however, take safeguards to help minimize or eliminate junk faxes in two ways:

1) If you can report the "Calling Number:" that the junk fax was sent from, we can then block this number from sending you any more faxes.

2) If you forward us the actual fax we will be able to block that number from sending junk faxes to all our customers.

What should I do if I did not receive a fax someone sent to me?

The first thing you should do is verify that the person sent the fax to the correct fax number. Most frequently, we find that the number was simply mis-dialed by the sending party. Another issue that we see is that your email service has blocked or filtered out our attempts to send emails to you, keeping us from being able to deliver your faxes. Double check your junk box or deleted items in your email to see if it is filtering out our attempts. Your faxes will be coming from the email address [email protected]. If these suggestions do not work, feel free to give us a call or send an email to [email protected].

What if someone faxed me multiple pages but I only received one page?

Some TIF viewers will only show the first page of a multipage TIF. We recommend trying a different graphics viewer or changing your incoming fax to PDF format.

Learn how to go to the next page of a fax in Windows Picture and Fax Viewer.

PDF files will open in Adobe Reader. Adobe Reader is a free viewer that most computers already have.

If you are using Mac OS you can view all pages of both TIF and PDF files in Preview. To do this, open the file in Preview.

Will anyone get a busy signal when attempting to send me a fax?

No, under normal conditions our fax service ensures that your customers will never receive a busy signal when faxing you documents. If you do hear of anything like this happening please contact our support.

How do I ensure that my faxes will not go into my junk folder or be filtered out?

You may find that your current email provider or client is blocking emails that contain important information such as the emails from Faxpipe.

How do I format the fax numbers in the email?

The fax number(s) should be the only content in the body of the email. Please make sure that there is no other text in the body of the email. No headers, footers etc.

You do not need to put a 1 before the number nor do you need to put parentheses, dashes, or spaces in the number.

If the fax is being sent to more than one fax number, please place each ten-digit fax number on its own line.

How do I send to multiple fax numbers?

Sending a fax to multiple fax numbers is just as easy as sending a fax to one fax number. Place each ten-digit fax number in the body of the email with one fax number per line.


What type of documents can I send as a fax?

  • .doc and .docx (Microsoft Word Documents)
  • .tif and .tiff (Tagged Image File)
  • .txt and .text (Plain text)
  • . prn and .ps (PostScript)
  • .pdf (Adobe PDF)
  • .html and .htm (HTML Document)
  • .rtf (Rich Text Format)
  • .jpg and .jpeg (Joint Photographic Experts Group)
  • .xls and .xlsx (Microsoft Excel Document)
  • .fdx (Winfax)

  • .gif (Graphics Interchange Format)
  • *. odt (Open Office Document)
  • *. wpd (Word Perfect Document)
* File types are accepted but may not appear exactly as seen in the original document.

Will I receive a confirmation that my faxes have been sent?

Yes, you will receive two confirmation emails.

The first email you will receive will confirm that the fax has been successfully queued and will be sent shortly.

The second email will notify you if the fax was successfully sent or if there was an error during delivery.

Was my fax sent if I did not receive a "Queued" or "Fail" confirmation?

The most common reason that you do not receive a Queued confirmation is that you have sent the fax request from an email address that was not enabled. Before you can send outbound faxes, you will need to provide us a list of emails that we will enable to send outbound faxes. If the email you used is an authorized address, we would have sent you the QUEUED or FAIL and it was simply filtered out in your email account. For security purposes we only accept fax request emails from addresses that you specifically approve with us. If you have sent the email from an unauthorized email address the fax will not be sent.

Why am I getting an email response of "No fax numbers found"?

This is a notification that you did not place a fax number in the body of the email, or our system was unable to recognize the fax number. The reasons our system wouldn't recognize fax numbers are:
  • You have placed text in front of the fax number. Fax numbers need to be the first and only thing in the body of the email.
  • You typed fewer than the required ten digits of the fax number. Fax numbers need to be ten digits long, with nothing else before the number.
  • You may need to change your email format to plain text. This is different depending on your email client.
NOTE: Please be sure not to include a signature in your email. Our system will attempt to call any phone or fax number in a signature and deliver a fax, so your phone will be ringing as we try to deliver a fax to that number.

Why am I getting an email response of "No valid attachment"?

This is a notification that you did not attach a file type supported by our system or you did not attach anything at all.

If you have just changed the extension on the file, our system will recognize the original file type and will not allow it to go through. If you need to change the file extension, we suggest you open the file in a different program and save it as the desired file type.

Why did I receive an email that says " - winmail.dat - Error - Invalid file extension."?

This is notification that there is a file attached to your email called winmail.dat. This is an Outlook or Outlook Express file; normally containing your header or footer information. To remove this file, follow these steps:

In Outlook:
  1. Click on Tools, Options, Mail Format
  2. In Compose in this message format, click on Plain Text and then hit OK.
In Outlook Express:
  • Start a new email, click on Format, select Plain Text

Sending Faxes: How do I send a fax using my Faxpipe account?

All Faxpipe accounts are automatically enabled to receive faxes, but not send faxes. If you would like to enable this feature, contact our support team. Please note that this is a paid feature and you will need to have a paid account to utilize the outbound faxing service.

Once outbound faxing is enabled, you will receive an informational email with step-by-step instructions on how to send faxes. If you are unsure if outbound is enabled on your account, please contact us. If you have not received this email, we can easily resend it to you.

Sending a fax from your email can be done in three easy steps.

  1. 1) - Address the fax to be sent to your outbound Faxpipe email. Ex. fax(account number)
    • Write/create a new normal email. The subject line can be whatever you would like for your own reference; the recipient of the fax will not see this.
    • Please verify you are sending from the email you receive faxes with, or another email that is set up to send from your account.
  2. 2) - Place the number you want the fax sent to in the body of the email.

    For example:
    XXXXXXXXXX (the actual formatting of the numbers isn't important)
    • Nothing other than the numbers you are sending to should remain in the body of the email. In other words, erase everything and put ONLY the fax number(s) you are sending to (This includes signatures that are auto inserted)
    • If you are sending to more than one fax number at a time just put each 10 digit number on its own line
    • f you are sending internationally simply place your country code before the number you are sending to. For example, if you were in the U.S. you would put "011".
  3. 3) - Attach the document(s) to be faxed

    Simply attach the documents you wish to send as a fax.

    When you send your fax, you will receive two emails back from our server. First, you will receive a "queued" email to notify that the fax has successfully hit our system. Second, you will receive a "success" Email to verify successful delivery.

    The success email will contain a report on the fax transmission details. If an error has occurred, you will receive an error message alerting you that information is missing, such as the fax number or the attachment.

    Note: Anything entered into the subject line is not put into the fax, it is merely for your own records.

A Few Additional Tips

  • If you don't receive a queued or success email, make sure the address you sent from is one enabled on your account. Also check your spam or junk folders to see if any auto responses from our system were filtered there.
  • If you get an email back from us saying "No Fax Number(s) Found" try sending the email again in "plain text" format.
  • Faxes normally take less than a minute to transmit after they have been in queue. To avoid extra time and/or overages on a fax, make sure that your document is set as black and white instead of grayscale.
Note: any color or high-resolution pictures will take additional time to fax.
