Quick Verdict: eFax is a reliable, enterprise-grade fax service — but at $18.99–$49.99/month, it's significantly overpriced for most users. If you're sending fewer than 500 faxes a month and don't need a corporate support contract, there are better-value alternatives. mFax.to gives you mobile faxing for far less.
eFax has been around since 1996 — long before "cloud faxing" was even a phrase. With 11 million users and 25+ years of history, it's the category pioneer. But in 2026, that legacy comes with a premium price tag and a user interface that hasn't kept pace.
This review covers everything you need to know: how eFax works, what it costs, who it's genuinely good for, and when you're better off with a leaner alternative.
Who This Review Is For
This review is for individuals, small businesses, and healthcare/legal teams evaluating eFax. We've tested the interface, reviewed 2,000+ user reports, and compared pricing against major alternatives as of March 2026.
eFax at a Glance
eFax is the most established online fax service in the market, built for enterprises, healthcare organizations, and legal teams that need bulletproof reliability and compliance. For everyone else, the pricing is hard to justify.
Pros
- 25+ years of reliability — nearly 100% uptime
- 24/7 phone AND chat support (rare in this category)
- HITRUST certified — gold standard for healthcare
- Sends to 200+ countries, 170+ file formats supported
- Up to 3 GB attachments per fax
- jSign integration for e-signatures on the same platform
- API available for enterprise integrations
Cons
- Expensive: $18.99–$49.99+/month versus competitors at $7–$13
- HIPAA compliance locked behind $49.99/mo Protect plan
- No free trial — discounted first month requires credit card
- Outdated desktop and mobile interface
- Significant billing complaints and cancellation friction
- Complex overage pricing ($0.10–$0.15 per extra page)
- Low 1.1/5 rating on ConsumerAffairs despite 4.5/5 on Trustpilot
Is eFax Worth It? (Review Verdict)
We rate eFax 3.5/5. It's worth it for enterprises and healthcare teams that genuinely need its reliability, 24/7 phone support, and HITRUST compliance. For everyone else, the $18.99–$49.99/month pricing, HIPAA locked behind the $49.99 Protect plan, and documented billing and cancellation friction make cheaper alternatives the smarter choice.
eFax Pricing Plans (2026)
eFax's pricing is structured around three tiers. Annual billing saves up to 17% on each plan.
Plus
- 170 pages/month
- 1 user
- HIPAA compliant
Best for individuals. Local fax number included. Overage: $0.10/page.
Pro
- 275 pages/month
- Up to 5 users
- HIPAA compliant
Small teams. Local or toll-free number. Overage: $0.10/page.
Protect
- 500–25,000+ pages/month
- Up to 5 users
- HIPAA compliant
Healthcare, legal, regulated industries. BAA included. Custom enterprise pricing available.
Watch Out for the First-Month Discount
eFax advertises first months at $5–$15 to make signup feel low-risk. After that, full pricing kicks in automatically. You must cancel before the billing cycle ends to avoid charges — and cancellation has been a documented pain point for users.
How eFax Pricing Compares to the Market
| Service | Starting Price | Pages Included | Free Trial | HIPAA | Best For |
|---|---|---|---|---|---|
| mFax.to | Pay-per-fax or sub | Flexible | Yes | Business plan | Mobile & occasional users |
| eFax Plus | $18.99/mo | 170 | Discounted 1st mo | Protect only ($49.99) | Enterprise & healthcare |
| Fax.Plus | $6.99/mo | 200 | Free tier available | Business plans | Budget-conscious teams |
| MetroFax | $7.95/mo | 500 | Yes (30 days) | No | High-volume senders |
| RingCentral Fax | $7.99/mo | 750 | Yes | Yes (paid plan) | Teams on RingCentral already |
| HelloFax | $9.99/mo | 300 | Free tier | No | Google Workspace users |
| iFax | $12.49/mo | 200 | 7-day trial | Yes | HIPAA at lower cost |
The numbers tell the story: MetroFax offers 3× the pages for less than half of eFax's base price. RingCentral Fax offers 4× the pages at $7.99. eFax's premium is justified only if you genuinely need its enterprise-grade compliance and 24/7 phone support.
eFax Key Features
What eFax Does Well
Reliability and uptime are the bedrock of eFax's value proposition. In 25+ years of operation, the service has maintained near-100% uptime — a critical factor for healthcare providers who can't afford failed fax transmissions.
24/7 phone and live chat support is genuinely rare in this category. Most fax services limit support to email tickets or business-hours chat. If you're a practice manager who needs help at 2 AM before a compliance deadline, that matters.
HITRUST CSF certification is the gold standard for healthcare data security — more rigorous than self-attested HIPAA compliance. If your organization requires HITRUST, eFax Protect is one of the few fax services that qualifies.
Global reach covers 200+ countries with fax delivery. For law firms handling international contracts or healthcare organizations with cross-border partners, this breadth is useful.
File format flexibility supports 170+ formats including PDF, Word, Excel, PowerPoint, and most image types. Files up to 3 GB can be attached — far beyond what most services allow.
Where eFax Falls Short
Pricing is the primary complaint. For $18.99/month, you get 170 pages — that's $0.11 per page before overages. Competitors at half the price give you 300–750 pages. For small businesses and individuals, you're paying a significant premium for brand recognition.
HIPAA compliance requires the Protect plan. This is a common source of frustration. Users who sign up for Plus or Pro believing they're getting HIPAA-compliant faxing are wrong — the Business Associate Agreement (BAA) is only on Protect plans starting at $49.99/month.
HIPAA Trap: Don't Assume All Plans Are Compliant
Only the Protect plan ($49.99+/month) includes a BAA and full HIPAA compliance. The Plus and Pro plans do NOT qualify for healthcare use involving PHI. If you work in healthcare and need HIPAA faxing at lower cost, consider mFax Business starting at about $9/mo (billed annually). Unlike eFax's rigid tiers, mFax Business lets you build your own plan — pick the exact seats and pages you need and pay only for what you use.
The interface feels dated. The web portal and mobile apps haven't received major design updates in years. Compared to the clean, modern UX of newer competitors, eFax feels like software from a previous decade.
Billing and cancellation issues are well-documented. ConsumerAffairs shows a 1.1/5 rating (versus 4.5/5 on Trustpilot — a notable discrepancy). The negative reviews consistently mention unexpected charges, difficulty canceling, and auto-renewal surprises. These aren't isolated complaints.

Who Should Use eFax
eFax makes sense in a narrow set of circumstances:
eFax IS a Good Fit If You…
- • Need HITRUST-certified compliance (healthcare enterprise)
- • Require 24/7 phone support as a contractual guarantee
- • Send faxes internationally to 200+ countries regularly
- • Are a large enterprise needing a fax API and custom SLAs
- • Already integrated eFax into existing systems and switching costs are high
eFax Is NOT a Good Fit If You…
- • Are an individual or small team looking for value
- • Need HIPAA compliance but can't afford $49.99+/month
- • Want a clean, modern mobile faxing experience
- • Only need to send faxes occasionally (pay-per-fax is smarter)
- • Are concerned about billing flexibility and easy cancellation
Best eFax Alternatives
If eFax's pricing doesn't fit your needs, here are the alternatives worth considering, sorted by use case:
Best for Mobile Faxing: mFax
mFax.to is built for exactly the use case where eFax is overkill: individuals and small teams who need to fax documents from their phone quickly and without a steep monthly bill. Open the app, upload your PDF or snap a photo, enter the fax number, and send. The whole process takes under 2 minutes.
With 5 million+ users and a 4.8-star App Store rating, mFax has become the go-to mobile fax app. For teams, mFax Business starts at about $9/mo and includes HIPAA compliance — a fraction of eFax Protect's starting price.
See the full comparison: mFax vs. eFax — which is better for your use case.
Best for Budget Teams: Fax.Plus
At $6.99/month for 200 pages, Fax.Plus undercuts eFax dramatically. It also offers a free tier (limited pages), which eFax does not. HIPAA-compliant plans are available at higher tiers. The mobile app is more modern than eFax's.
Best for High Volume: MetroFax
MetroFax's $7.95/month plan includes 500 pages — nearly 3× what eFax's $18.99 plan offers. No free trial, no HIPAA, but for plain-vanilla high-volume faxing it's hard to beat on value.
Best for Teams Already on RingCentral: RingCentral Fax
If your business already uses RingCentral for phone/messaging, adding fax at $7.99/month with 750 pages/month is a no-brainer. The integration is seamless and the per-page economics are excellent.
Best for Occasional Use: Pay-as-You-Go Services
If you send fewer than 5 faxes per month, a monthly subscription is wasteful. Options like FaxZero (free, 3 pages) and PayPerFax work for occasional needs. Our full guide: best pay-as-you-go fax services.
eFax Security & Compliance
eFax's security story is genuinely strong — but it's tiered:
| Feature | Plus / Pro | Protect Plan |
|---|---|---|
| TLS encryption in transit | ✅ | ✅ |
| AES 256-bit encryption at rest | ❌ | ✅ |
| HIPAA compliant + BAA | ❌ | ✅ |
| HITRUST CSF certified | ❌ | ✅ |
| jSign e-signatures | ❌ | ✅ |
| Audit logs | Limited | Full |

When eFax's Security Premium Pays Off
If your organization is going through a HITRUST certification audit, eFax's Protect plan simplifies the process considerably — it's one of very few fax services with pre-existing HITRUST CSF certification. For healthcare enterprises, that compliance shortcut has real dollar value.
eFax vs. mFax: Side-by-Side
| eFax Plus | mFax Business | |
|---|---|---|
| Starting price | $18.99/mo | From $9/mo |
| HIPAA compliance | ❌ (needs Protect at $49.99) | ✅ included |
| Mobile app quality | Dated | Modern (4.8 ⭐) |
| Free trial | No (discounted 1st month) | Yes |
| Pages included | 170 | 500+ |
| 24/7 phone support | ✅ | Chat + email |
| HITRUST certified | Protect plan only | No |
| Best for | Large enterprise | Small business & healthcare teams |
If HITRUST certification and 24/7 phone support aren't requirements, mFax Business gives you more pages, better mobile experience, and HIPAA compliance at a lower price.
Final Verdict
eFax earns its reputation — but that reputation was built in an era when it had no real competition. In 2026, the online fax market has matured, and eFax's price premium is increasingly hard to justify for anyone outside large enterprises.
Choose eFax if you need HITRUST certification, enterprise-grade SLAs, or 24/7 phone support — and your organization can absorb $50–$750/month in fax infrastructure costs.
Choose mFax if you want a modern, mobile-first fax service with HIPAA compliance at a fraction of the cost. mFax.to is the fastest way to send a fax from your phone, and mFax Business handles team faxing with HIPAA compliance starting at about $9/mo.
Choose Fax.Plus or MetroFax if you need the lowest possible monthly cost for personal or small-business faxing.
Whatever service you use, always verify that it includes a signed BAA before sending any protected health information.
