Extreme Fax offers most of the basic features that other online fax services provide. This service enables users to send and receive faxes to and from an email account. The service is easy to use, if you have experience sending and receiving emails and know how to add attachments.

This service supports 300 send/receive faxes per month. Above 300 faxes, additional faxes cost 6.7 cents/ea. This service also enables you to send local or international faxes either through your email account or through the Extreme Fax web interface.

We tried to contact this service several occasions through their email address. We expected a quick response to our questions; however, we never received a reply. This service also provides a toll free phone number and a FAQ section.

Overall, Extreme Fax offers many of the same features as their competitors.
