Green-Fax offers a faxing solution that is more efficient and environmentally friendly than traditional fax machines. Their fax-to-email and email-to-fax services allow users to send and receive faxes via email rather than using paper and ink. Setting up either service takes simple steps and can be completed within 24 hours. Green-Fax costs just ?50 per year for one email account, saving users money compared to costs of fax machines and phone lines.
