EtherFax vs Sfax (2026): which should you pick?

Pick EtherFax if

• Fits if you are a hospital or clinic swapping faxes with Epic or OnBase
• Works for agencies that need a FedRAMP-listed fax service

Look elsewhere if

• Not for you if you want a price before you talk to anyone, because none is published
• Skip it if you are one person who wants to sign up and send a fax today
• Watch out: email faxing is described for Microsoft 365 and Google Workspace users only
• Watch out: it is pitched at organizations and workflows, so a small office may find it more than it needs

Pick Sfax if

• Fits if your medical office needs an audit trail on every fax
• Works for practices that fax from desktop programs through a print driver

Look elsewhere if

• Not for you if you want to see a price first, as none could be read from Sfax's pages
• Watch out: the trial is a paid plan you must cancel within 14 days, and monthly plans need 30 days' notice to cancel
• Skip it if you use Android, or Windows older than 11, as neither is supported
• Tight if you need several lines, since plans include one toll-free line and each extra is $5 a month

EtherFax

• No prices are published; the site directs visitors to contact the company.
• Aimed at organizations, with no self-serve plan for individuals.
• Email faxing is described for Microsoft 365 and Google Workspace users.

• Plans include one toll-free line; each extra line is $5 a month on monthly plans or $48 a year on annual plans.
• Cancelling a monthly plan needs 30 days' notice by support ticket or email, with no refunds or partial months after the first 14 days.
• The Windows app supports only Windows 11 on x64 or x86, and the help center lists an iPhone app but no Android app.
