I guess the best one could say is that they send faxes. Their pricing is also reasonable.
I also liked that you can store past contacts.
Their user interface is outdated and a challenge to use.
Worst of all is their dishonest cancellation policy. They deliberately make it difficult to cancel and refuse to honor cancellation requests without jumping through hoops. They use the Hotel California as model - you can sign up, but you can never leave.
When trying to cancel, they only offered an email address. When emailing them, they require calling a specific phone number during specific hours and require an agents "help" in cancelling.
When trying to send a fax, you first had to create a contact, rather than simply entering the fax numbers.
Avoid it! Please read the reviews across the web and you'll see that their reputation is rightfully mud.
You can send faxes.
The benefits of sending a fax are minimal sometimes necessary when dealing with certain vendor.
