FAQ about Web Fax Services

Sending Faxes:
ArrowHow do I send a fax using my AirComUSA paid account?

How do I send a fax using my AirComUSA paid account? In order to send faxes you need to have a paying account, not a trial account. We must enable the outbound capability on your account separately from your initial account activation. There is no additional cost. Please notify AirComUSA if you would like to activate this feature. Once outbound faxing is enabled, you will receive an instructional email with details on how to send faxes. If you have not received this email or are unsure if outbound is enabled on your account, please contact us. If you have lost the instructional email, we can easily resend it to you. To contact us click here.

Sending a fax can be done in three easy steps.

  • 1) Make sure you are sending the email from the email address you have provided to AirComUSA. Send the email to the address AirComUSA has provided for you
    (see above paragraph: instructional email).
  • 2) Put the ten digit fax number into the body of the email. Make sure there is nothing else in the body of the email. No punctuation or leading "1" is necessary in the fax number.
  • 3) Attach an appropriate file that you wish to fax and push "send".

Note: Anything entered into the subject line is not put into the fax, it is merely for your own records. When you send your fax you will receive two emails back from our server. The first either confirming the receipt and proper queuing of the fax, or an error message alerting you that information is missing, such as the fax number or the attachment. Upon successful delivery you will receive a "Success" email with a report on the fax transmission details.

ArrowWhat email address do I send to?

The email address to send your email to fax requests to will be provided to you after you have registered for a paid account. If you are registered, and have not received this email please contact AirComUSA.

ArrowWhat email address(es) do I send from?

When sending an email to fax request you need to send the request from the email address(es) you have provided to AirComUSA. If you would like to add or change an email address please contact AirComUSA.

ArrowHow 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.

ArrowHow 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.



ArrowWhat 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)

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

Yes, you will receive two confirmation emails. The first email will tell you one of two things one, that we have successfully received your fax and it is queued for delivery or two that there was a problem with the fax and we were not able to send it.

The second conformation report that you will receive will tell you how long it took for us to send your fax and if there were any problems sending your fax.

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

Most of the time if this occurs, you have sent the fax request from an email address that was not given to us as an authorized address, or we 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.

ArrowWhy 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.

ArrowWhy 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 can tell what type of file it really is 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.

Receiving Faxes:
ArrowHow do I view received faxes?

Your fax document(s) will be delivered to you via email as attachments. They are sent to the email account that you provide for us. The attachment will either be in .tif or .pdf format.

By default, Windows opens .tif faxes with "Windows Picture and Fax Viewer". If your computer opens faxes in another program, and you want to learn how to make your faxes open with the default Windows program, click here. Faxes in .pdf format open in the free Adobe Reader and in Preview for MacOS.

ArrowWhat 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. To change your preference to .pdf, call us and we will quickly configure your account for you.

ArrowCan I receive faxes at multiple email addresses?

Yes! You can receive your faxes at up to 5 email addresses, at no additional charge. Simply give us a call, or send an email and we will happily add, remove or modify any email address on your account.

ArrowDo 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 and faxes can easily be viewed in Windows Picture and Fax Viewer for Windows or Preview for MacOS.

ArrowWill AirComUSA 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.

ArrowWhat 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 are able to 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 of our customers.

ArrowWhat 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].

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

If you are receiving your faxes as .tif files you may want to change the program your faxes are opened with to Windows Picture and Fax Viewer.

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. Under the "View" option, select "Drawer". This should open up a side window that will allow you to see and select the different pages of the fax.

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

No, our fax service ensures that your customers will never receive a busy signal when faxing you documents.

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

Security  Can AirCom improve my company's security?

AirCom takes security very seriously. Easy to say and talk about, but the proof is "in the pudding". In the 15 years AirCom has been in business we have never experienced a security breach of any kind. Amazing? We don't think so. We have created our system from the ground up with security and stability at the forefront of our mission. Nobody comes behind our firewalls. Period.

We have intentionally "lagged behind the pack" when it comes to online options and features. While it would be nice to allow our customers to make changes to their own accounts, it opens up vulnerabilities in our network that we won't tolerate. Not only is our network impenetrable, but we also have world class customer service. Your calls are answered with live agents that can instantly make the necessary changes to your account. It's even faster and easier than doing yourself.

AirCom has the security on our end covered. Now, we want to help your company improve the way it manages sensitive documents. Having documents faxed into a traditional fax machine is a poor way to protect your clients information. It also violates (in most cases) HIPAA, GLBA and many state and Federal Laws governing information security. Identity theft is rampant and a single security breach could damage your business and reputation. Do not take security lightly.

HIPPA  How does AirCom help make my company HIPPA compliant?

The Health Insurance Portablility & Accountability Act (HIPAA) applies to all entities that record, maintain, or transmit personal health information- as well as those who service or support healthcare entities. Heavy fines and penalties for negligence can be assessed against your business. Owners and officers can be held personally liable.

Leaving personal health records on top of a fax machine, where patients or visitors to your facility could easily gain access, is irresponsible. Todays world is far less forgiving than it used to be. There is no excuse for anyone other than the intended recipient to have access to faxed documents. This is one of the hottest issues we are all dealing with. Don.t be the one who drops the ball by taking security lightly.

AirCom helps you meet and exceed all of the regulations regarding how faxed documents are to be managed. Please call for more information regarding this very important issue.
