Impossible to get any customer service. They never answer their emails or phone calls. I have tried to contact them 10+ times in the past 2 weeks and have sent numerous emails to support with no reply. No one has ever answered the phone and I'm always sent to voicemail. It frustrating trying to operate a medical office and not have our fax account work. This is something we use frequently and this issue needs to be handled right away but it's impossible to get any help.

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?

Locks me out too fast As an efax it has many features I like and expect, tracking, ability to look back etc. But Everytime I leave the page I have to sign back in. It is often very slow to load, and cumbersome to search. It's just OK

SCAM COMPANY SCAM COMPANY. Signed up for a free trial. Immediately unimpressed by the interface. I emailed to cancel the same day and called. No one picks up their phone. It's a voicemail. Fast forward 10 days, two emails, two unreturned voicemails later, they've charged my credit card despite my requests to cancel. I'm disputing with my credit card company.

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.
