eFax vs SupaFAX: Why Pay $17/Month to Send One Fax?

eFax is one of the most-searched fax services on the internet. Millions of people land on it every month because it ranks well for "fax app" and "send fax online." But if you actually look at the pricing, you might be surprised by what you're signing up for.

Let's break down eFax vs SupaFAX honestly — no affiliate incentives, just math.

eFax pricing (as of 2026)

eFax's standard plan runs $16.95/month ($203.40/year). That includes:

• 150 pages sent + 150 pages received per month
• A dedicated fax number
• Overage fees beyond 150 pages ($0.10–$0.15/page)

There's also a cheaper "Basic" tier at ~$9.95/month, but it comes with a one-time setup fee and fewer included pages.

SupaFAX pricing

SupaFAX charges from $0.99 per fax, priced by page count, and the first one is free. No monthly fee. No setup fee. No dedicated number needed to send. Pay when you fax, nothing when you don't. If you fax often, SupaFAX Unlimited is $59.99 a year, and a fax number for receiving is $6.99 a month.

The math

If you send faxes occasionally — say, once or twice a year — here's what each service costs you. SupaFAX figures assume a typical 2–5 page fax at $1.99, switching to Unlimited ($59.99/year) once that is cheaper:

There is no break-even point on price. Past about 30 faxes a year, SupaFAX Unlimited caps what you pay at $59.99 a year — less than a third of eFax. If you're a medical office or law firm, eFax's enterprise features may still matter. If you're a normal person who needs to fax their insurance once in a while, a subscription doesn't.

What eFax does better

To be fair: eFax and similar services offer things SupaFAX doesn't (yet):

• High volume — 150 pages/month included makes sense for offices
• Enterprise features — multi-user accounts, API access, integration with EHRs

SupaFAX does receive faxes now: a dedicated number is $6.99 a month, or included in the $99.99/year Unlimited + Number plan. But if you need multi-user accounts or EHR integrations, an enterprise service is the right tool.

What SupaFAX does better

• Price — from $0.99 per fax vs $16.95/month
• Zero commitment — pay per fax, no subscription needed
• Mobile-first — built for iPhone and Android from the ground up
• Speed — scan and send in under 60 seconds
• No account required — just open and fax

Which is the best fax app for iPhone?

It depends on your use case. For occasional, one-off faxes — sending a form to your doctor, faxing a rental agreement, submitting a legal document — SupaFAX is the clear winner on price and simplicity. For businesses that need multi-user accounts and integrations, an enterprise service gives you more infrastructure.

The key question: How many faxes do you actually send per year? For most people, the honest answer is "fewer than 10." For those people, paying $203/year for a fax subscription is like paying for a gym membership to use the scale once a month.

The bottom line

eFax is a solid product built for volume. SupaFAX is built for everyone else — the vast majority of people who need to fax something occasionally and don't want to pay a monthly fee for the privilege.

From $0.99 a fax, SupaFAX is the best fax app for iPhone users who value simplicity and fair pricing. Download it on iOS or Android and send your first fax in under two minutes.
