Fax.Plus Review 2026: Pricing, Free Plan & HIPAA — Is It Worth It?

By David Thompson · Published December 16, 2024 · Updated June 8, 2026 · 13 min read

Quick Verdict: Fax.Plus (3.8/5) is a polished, affordable online fax service — 10 free pages, paid plans from $6.99/mo (annual) — but HIPAA/BAA is locked to the $79.99/mo Enterprise tier and support is email-only. Trustpilot shows a striking 50/43 split between five-star and one-star reviews. Worth considering — with eyes open.

Fax.Plus (often written FaxPlus) launched under the Alohi umbrella (Geneva, Switzerland) and has quietly grown to 4 million+ customers worldwide. It sits in an interesting position in the fax market: priced aggressively below legacy services like eFax, but more feature-rich and design-conscious than bare-bones alternatives.

In 2025, Alohi shipped a notable wave of improvements: HD faxing for image-heavy documents, Auto Resume (which automatically retries partially-sent faxes, saving page credits), a redesigned inbox, and even MCP integration for AI agent workflows. The product is actively developed — which matters in a category where many players coast on decade-old infrastructure.

This review covers pricing, features, real user feedback, and who Fax.Plus is (and isn't) right for.

Fax.Plus at a Glance

Fax.Plus Pricing Plans (2026)

Fax.Plus uses annual and monthly billing. The prices below are billed annually — monthly rates are about 25% higher.

There is also a Business plan ($27.99/month annually) at 1,000 pages for up to 5 users — useful for small teams that don't need HIPAA compliance. Monthly pricing is $8.99 (Basic), $17.99 (Premium), $34.99 (Business), and $99.99 (Enterprise).

How Fax.Plus Pricing Compares

For pure value on page count, RingCentral Fax (750 pages at $7.99) and MetroFax (500 pages at $7.95) beat Fax.Plus Basic (200 pages at $6.99). But Fax.Plus wins on interface quality, international reach, and the Alohi ecosystem integrations.

Fax.Plus Key Features

What Fax.Plus Does Well

Interface and mobile experience are the standout positives. The web app is clean, well-organized, and clearly maintained — a meaningful contrast to services like eFax that haven't updated their UI in years. The iOS app holds a 4.7-star rating across 8,000+ App Store reviews. For users who primarily fax from a phone, that level of polish matters.

International coverage is genuinely best-in-class. Fax.Plus lets you send to 180+ countries and get virtual fax numbers from 48+ countries — useful for law firms with overseas clients, importers and exporters, or anyone sending documents across borders. For a deep dive on international faxing considerations, see our complete guide to international faxing.

Swiss data privacy and security certifications differentiate Fax.Plus from US-based competitors. ISO/IEC 27001 and SOC 2 Type 2 certifications are legitimate enterprise credentials. The ability to choose your data residency region (20+ options including Switzerland, Canada, and Australia) is a real advantage for organizations with data sovereignty requirements. For healthcare teams evaluating compliance, see our overview of what makes a fax service truly secure.

Integrations cover the major cloud storage providers (Google Drive, Dropbox, OneDrive, Box, iCloud), plus Slack notifications on Business plans and above. Zapier support extends connectivity to thousands of other tools without code. The December 2025 addition of MCP (Model Context Protocol) support positions Fax.Plus ahead of most competitors for AI-assisted document workflows.

Auto Resume (launched November 2025) automatically retries partially-sent faxes without consuming additional page credits. This is a genuine quality-of-life improvement for users who send long or complex documents that occasionally stall mid-transmission.

Where Fax.Plus Falls Short

HIPAA compliance requires the Enterprise tier. This is the single biggest structural weakness. The Business plan at $27.99/month supports up to 5 users and 1,000 pages — but it doesn't include a BAA and is not HIPAA compliant. Moving to Enterprise jumps to $79.99/month. Healthcare organizations with modest faxing needs are effectively forced into a plan priced for large organizations.

Fax.Plus Support and Customer Service

Email-only support is a recurring complaint. Fax.Plus offers no live chat, no phone line, and no defined SLA for response times. When billing disputes or failed fax issues arise — and based on Trustpilot, they do arise — there is no fast escalation path. For businesses where faxing is mission-critical, this is a meaningful risk.

The Trustpilot score deserves scrutiny. An overall 3.8/5 looks reasonable until you look at the distribution: 50% of reviewers give 5 stars, 43% give 1 star. This bimodal pattern typically indicates a service where most customers have a seamless experience but a significant minority encounter billing problems or technical failures with no easy resolution. The negative reviews concentrate on: unexpected annual charges after monthly signups, difficulty getting refunds, and faxes showing as "sent" but not received by the destination.

Page-per-fax caps on lower tiers are limiting. The Basic plan caps a single fax at 60 pages — insufficient for contracts, hospital records transfers, or court filings that run longer. Premium raises this to 90 pages. You need Business or above for the 200-page cap.

How Fax.Plus Works

Who Should Use Fax.Plus

Fax.Plus Security and Compliance

Fax.Plus has invested meaningfully in security certifications — more so than many comparably priced competitors:

The ISO 27001 and SOC 2 Type 2 certifications are legitimate third-party audited standards — not self-attested claims. The unique encryption key per user (rather than a shared key) is a stronger-than-average implementation for a service at this price point.

The data residency flexibility is notable: if your organization needs data stored in Switzerland (under Swiss Federal Act on Data Protection), Canada, Australia, or another specific jurisdiction, Fax.Plus supports it. This is rare at the Basic and Premium price tiers.

Fax.Plus vs. the Alternatives

Best Alternative for HIPAA and Mobile: mFax

mFax.to is the strongest alternative for users who need either mobile-first faxing or HIPAA compliance without Enterprise pricing. The mFax consumer app has a 4.8-star App Store rating across 5 million+ users — slightly higher than Fax.Plus's 4.7-star score — and the send-in-under-2-minutes workflow is hard to beat for occasional use.

For teams, mFax Business delivers HIPAA compliance with a BAA starting at about $9/mo — well under a third the cost of Fax.Plus Enterprise. Rather than locking you into rigid tiers, mFax Business is fully customizable: you build your own plan with a live calculator, picking the exact number of seats (1–35) and pages (200–5,000) you need and paying only for that. That gap is difficult to ignore for healthcare practices with modest fax volume. See our best HIPAA-compliant fax services roundup for the full comparison.

Best Legacy Alternative: eFax

eFax is the category incumbent — 25+ years of operation, near-100% uptime, HITRUST CSF certification, and 24/7 phone support. If you need the gold standard for enterprise healthcare compliance or a vendor with a long contractual track record, eFax Protect is the answer. But it costs $18.99–$49.99+/month with fewer pages per dollar than Fax.Plus. See our full eFax review for a detailed breakdown.

Best for High Volume on a Budget: MetroFax

MetroFax gives you 500 pages/month for $7.95 — more than double Fax.Plus Basic's 200 pages at a nearly identical price. No HIPAA, no advanced integrations, no Swiss privacy story — but for straightforward high-volume domestic faxing, it's hard to beat on economics.

Best for Occasional Faxing

If you send fewer than 5–10 faxes per month, any monthly subscription is wasteful. The mFax app lets you pay per fax with no ongoing commitment. See our guide to pay-as-you-go fax services for one-time options.

iFax is also commonly cited in roundups as a top Fax.Plus alternative. If your priority is HIPAA compliance plus a strong mobile experience without Enterprise pricing, mFax remains our pick — a BAA and HIPAA-compliant faxing from about $9/mo, paired with a 4.8-star mobile app.

The Trustpilot Problem: What's Really Going On

The 3.8/5 Trustpilot score conceals an unusually polarized user experience. Of 178 reviews: 50% give 5 stars, 43% give 1 star. This is not a service where most users have a mediocre experience — it's a service where most users are happy, but a significant minority hits a wall.

The negative reviews cluster around three themes:

1. Accidental annual billing — users sign up for monthly plans and are charged for a full year, often with a non-refund policy cited in response.
2. Page count discrepancies — several reviewers report being charged for more pages than their fax contained.
3. Failed faxes with no credit — faxes that show as sent but aren't received by the destination, with difficulty recovering credits through email-only support.

The positive reviews praise the interface, delivery reliability, and (notably) responsive email support. The divergence suggests the service works well when it works and becomes frustrating when something goes wrong.

Final Verdict

Fax.Plus earns its reputation as the best-value dedicated fax service for non-HIPAA use cases. The pricing is genuinely competitive, the interface is modern, the international coverage is unmatched, and the 2025 feature releases (HD faxing, Auto Resume, AI/MCP integration) demonstrate that the product is actively improving.

For casual users, freelancers, and small businesses that send domestic or international faxes without a healthcare compliance requirement, Fax.Plus Basic or Premium is a strong choice — especially compared to paying eFax's $18.99/month for 170 pages.

Where Fax.Plus falls down is the HIPAA pricing structure and the support model. The $52/month jump from Business to Enterprise solely to access a BAA is punishing for small healthcare teams. And when billing problems arise — and the Trustpilot distribution suggests they do — email-only support with an unclear SLA is not the safety net most organizations need.

Choose Fax.Plus if you're a freelancer, small business, or international user who wants a polished, affordable fax service with strong data privacy credentials and don't need HIPAA compliance.

Choose mFax if you want the fastest mobile faxing experience, need HIPAA compliance at a manageable price, or prefer a service with a more consistent user satisfaction track record. Download the mFax app to send your first fax in under 2 minutes — or explore mFax Business for teams starting at about $9/mo with HIPAA compliance included.

Choose eFax if your enterprise requires HITRUST CSF certification or contractually guaranteed 24/7 phone support.
