Internet Fax

Despite the explosive shift to digital communications, there can still sometimes be a need for old-style analog facsimile (fax), but thanks to the Internet it's no longer necessary to have a fax machine and fax phone line.
The principal drawback to Internet fax can be cost, in that many Internet fax services are monthly subscription plans, but if your needs are modest, here's how to do fax over the Internet on the cheap (best deals as of this writing):

• Incoming: Free service from eFax. You'll be given an incoming fax number, and your incoming faxes will be sent to you by email. To view (or print) faxes received by email, you'll need to download and install eFax Messenger software.
• Outgoing: Pay As You Go service from Fax1. Currently $0.12 per delivered page to the USA. (International rates here) $1 free trial credit to get started; buy more credit as needed. Download and install FaxBlaster software to print to fax from any software on your computer, or use any of several other faxing options. (Use the incoming eFax number when setting up your outgoing Fax1 account.)
  UPDATE: Fax1 no longer works properly and is not being supported.
  Instead, use a free personal account at FilesAnywhere to send up to 10 faxes per month. Fully professional quality and service, highly recommended!
