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 $1.99 per fax. No monthly fee. No setup fee. No dedicated number (you don't need one to send). Pay when you fax, nothing when you don't.

The math

If you send faxes occasionally — say, once or twice a year — here's what each service costs you:

The break-even point is around 102 faxes per year — roughly 2 faxes every week. If you're a medical office or law firm sending that volume, eFax (or a similar subscription) makes sense. If you're a normal person who needs to fax their insurance once in a while, it doesn't.

What eFax does better

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

• Incoming faxes — eFax gives you a dedicated number to receive faxes
• High volume — 150 pages/month included makes sense for offices
• Enterprise features — multi-user accounts, API access, integration with EHRs

If you need to receive faxes regularly, a subscription service is the right tool. SupaFAX is built for the sending side of the equation.

What SupaFAX does better

• Price — $1.99 per fax vs $16.95/month
• Zero commitment — no subscription, no cancellation 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 or anyone who receives faxes regularly, a subscription 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.

At $1.99 per 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.
