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.

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

Nonexistant support, incompetent staff Our experience with Sfax has been nothing but frustrating. E-mails to support on simple issues go unanswered. We tried to port our numbers over, but after 4 months the porting department seems to be unable to enter a port request properly even after being provided with a CSR from our current carrier. When we checked with our current carrier's port-out department, it looks like only half of the port requests are making it to them. We ported our voice numbers to a different vendor just before attempting to port our fax numbers and everything went fine. I'd recommend avoiding sfax or any j2 brand.

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.

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
