Eliminate your fax machine and have your faxes delivered directly to your email inbox as a PDF or TIF document. You can read them on your computer or smartphone, print them, save or forward them. If you can print and email form your computer, you can also send faxes from your computer. All plans include unlimited receiving. If you already have a fax number (including a toll free fax) you can keep your number. All you have to do is port your number to 559fax.com and you won't have to publish a new number. You can easily add additional lines if you have high volume. If you still need to have a physical machine to fax papers, you can use another line, and enhance your ability to receive faxes while sending.
