EnglishWhat is Paubox and what does it do?
Updated
Paubox is a HIPAA-compliant email and forms platform built for healthcare organizations. It lets you send encrypted email through Google and Microsoft without requiring recipients to use portals or passcodes, and it adds AI-powered email security, an email API, and email marketing tools on top of that core. It fits teams that need compliant patient communication without adding friction for senders or recipients.
Core product: HIPAA-compliant email
The main offering is encrypted email that works with the Google and Microsoft accounts your team already uses. Paubox describes the design goal as ease of use for both senders and recipients, removing the extra steps (separate portals, one-time passcodes) that typically slow down healthcare email.
- Encryption without recipient setup — the site states no portals or passcodes are needed.
- Works with existing providers — Google and Microsoft email are supported.
- Compliance built in — Paubox positions every layer of protection as meeting HIPAA standards by design.
AI-powered email security
Beyond encryption, Paubox adds generative-AI threat detection aimed at inbound attacks. The site cites that 54% of email security breaches start with malicious inbound emails, and that rule-based filters and default Microsoft/Google security settings miss sophisticated phishing.
How it works, per the site:
- AI analysis and detection — analyzes tone, sender behavior, and message intent to surface threats.
- Transparent insights — explains in plain language why an email was flagged.
- Continuous learning — refines its model of normal behavior to keep pace with new attack patterns.
The pitch is that this catches AI-engineered phishing and impersonation that traditional filters miss.
Additional solutions
| Solution | What it does | Who it's for |
|---|---|---|
| HIPAA-compliant email | Encrypted email via Google/Microsoft | Clinical and admin teams |
| AI email security | Generative-AI threat detection | Organizations facing phishing/ransomware risk |
| Email API | HIPAA-compliant transactional email | App developers |
| Email marketing | Build, send, track compliant campaigns | Patient outreach and marketing teams |
| HIPAA-compliant forms | Securely collect patient data | Intake and patient-facing workflows |
Who it's for
Paubox targets U.S. healthcare organizations that need to exchange PHI over email while staying compliant. The site states it is trusted by 9,000+ healthcare organizations. It's a reasonable fit if:
- Your team already runs Google or Microsoft email and wants encryption layered on top.
- You want recipients (patients, partners) to open messages without portal logins.
- You need to collect patient data through forms or send transactional/marketing email under the same compliance umbrella.
If you only need basic secure messaging and don't operate in a HIPAA context, the compliance focus may be more than you need.
What to check before deciding
- Pricing — the site links to a pricing page for the Email Suite; confirm current plans and limits there rather than assuming a free tier.
- Integration scope — verify your specific Google/Microsoft setup is supported.
- API and marketing needs — confirm these are included in the plan you're considering, since they're listed as separate solutions.
The site offers "Start free with email" and "Start free with Google" entry points, which is the practical way to test whether the no-portal, no-passcode experience works for your recipients.
