I see several companies offering "free" email to fax machine service, but I'm looking for a recommendation from an AMHD user who uses such a service.

I'm in the U.S.

Do any of you out there use this service that you are happy with?

I only have to fax something 3-4 times a year...

EFax offers a free online fax service that you can read more about at Ask Dave Taylor!. Though be warned, the free eFax website is always changing, so it may be difficult to find. If you're looking to fax only a few times a year, it should fit your needs perfectly.

Another route you can use to fax online for free is to sign up for free trials. This is a route I have taken in the past, and it's always worked for me. The only drawbacks of using this method are that you have to provide your credit card information and it can be annoying dealing with customer support to cancel your trial. I usually use FaxCompare.com to find free trials.
