eFax vs FaxZero (2026): which should you pick?

Pick eFax if

• Fits if you fax within the US and Canada and want it all in your email
• Works for small medical offices that want a signed BAA on a plan bought online, which is Business

Look elsewhere if

• Skip it if you fax abroad on Personal, which covers pages to the US and Canada only
• Pricey if you need a signed BAA, which Personal lacks; Business is $33.33 a month billed yearly
• Not for you if you want a desktop app on a Mac, as the print-to-fax app is Windows only
• Watch out: extra pages are 10 cents on Personal and 7 cents on Business, and international rates vary by country
• Watch out: on Business, extra users are $10 a month and extra numbers $5, and the API needs Corporate, priced by sales

Pick FaxZero if

• Fits if you need to send one fax to the US or Canada today
• Works for people who don't want an account or a subscription

Look elsewhere if

• Skip it if you need to receive faxes, because it has no number to receive on
• Tight if you send often: the free fax is 3 pages and 5 a day, with FaxZero branding
• Pricey if you send regularly, as each $3.29 fax adds up fast
• Watch out: international faxes are paid, at $3.63 for up to 15 pages in most countries, and the site runs ads

eFax

• The Personal plan covers pages to the US and Canada only and does not include a signed BAA; Business does.
• Pages over the plan cost 10 cents each on Personal and 7 cents on Business, and international rates vary by country.
• Extra users on Business are $10 a month each and extra numbers $5 a month each.
• The desktop app is for Windows; no Mac app is listed.

FaxZero

• The free fax is limited to 3 pages, 5 a day, and carries FaxZero branding on its cover page.
• The service is supported by advertising on the site.
• FaxZero's own FAQ says its API is offered through a sister service, edwyna.com, not FaxZero itself.
