This is a great e-fax system and is reasonable. You can send faxes from your email address and adding rcfax.com to your email address, and it is paperless. You can also receive faxes to your email address and it serves two purposes, the fax is scanned in and you can make a folder for it, and two you can access it from anywhere that you can connect your computer rather than having to be in the office to get the fax. There have been a few times when faxes have not come through due to size or just because. This is why I did not rate it 4 stars.
