FedEx is definitely reliable — I’ve used their fax machines many times when I needed something sent fast. But the prices can be high if you’re faxing multiple pages. The convenience is nice, yet after checking scramblerz.com, I learned that online fax platforms are just as secure and much cheaper. You can upload files from your phone, get instant confirmation, and even send international faxes for a low flat rate. If you only fax occasionally, FedEx works fine. But for regular use, digital faxing is the better deal — more flexible, faster, and available anytime without standing in line.
