  1. Go through the fee structures to look for hidden fees and avoid vendors that charge set-up fees.
  2. Before choosing a fax service, go through the list of supported countries to send faxes to as well as the list of countries that you are allowed to obtain a fax number from.
  3. To digitally receive faxes and send them back immediately, it is helpful if the service has an electronic signature feature.
