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.

Service works fine. Needs better salespeople and more tiers I get emailed monthly from a different salesperson trying to sell us the next package up because we get overages on our current plan. The next tier up will cost us MORE than what paying the overages would. I explain this to a different salesperson on a monthly basis. It's really frustrating. The service itself is simple and straightforward. I've always been satisfied with the system.

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.

Excellent except for one big flaw , can't send multiple files in one go See above see above see above

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.
