Not as effective receiving faxes as a traditional machine. We are unable to receive all faxes. 5% of income faxes are never received and we have to direct people to fax to our back office fax line Update: I have tried multiple times to have this issue resolved through support. I am told the person sending the fax has a problem with their phone line. but yet they can fax to my back office fax no problem. Tell me how that makes sense?

I have been a customer since April… I have been a customer since April 2017. Any time there is a customer service issue, it's concerning. For example, I have emailed and called 3 times this week. I just emailed again today. I need my fax to work. My billing is up to date, yet there are errors preventing me from changing my password. Customer service has been awful.

Excellent service. Reliable. Secure. I am not a heavy user of secure fax, however I am a critical user. I chose Sfax because it was the only one at the time which offered HIPAA security and also didn't require a big buy-in or monthly fee for occasional users. The security is still there but recent changes have made it less practical for occasional users like myself. If that does not apply because you are a business user, I can recommend Sfax without reservations.

So far so good We have been using sFax for a number of months now. It's working well except we are having a bit of trouble porting existing numbers which seems to take up to 2 weeks.

Will bill you regardless of canceling Faxes did send. My issue is with billing. I canceled by end of trial date. I never got a confirmation so I emailed 3 additional times and left 2 voicemails. Unsurprisingly I received a $29.00 bill. I do not recommend.
