How Flowmail Keeps Your Data Secure

Security-First Architecture

When you connect your email to Flowmail, you're trusting us with some of your most sensitive business data. We take that responsibility seriously.

From day one, we've designed Flowmail with a security-first architecture that ensures your data is protected at every layer.

Encryption Everywhere

Data at Rest

All sensitive data stored in Flowmail is encrypted using AES-256-GCM, the same encryption standard used by banks and government agencies. This includes:

Email content and metadata
OAuth tokens and credentials
Extracted business entities and fields

Data in Transit

All communication between your browser, our servers, and third-party services uses TLS 1.3 encryption. We enforce HTTPS everywhere with strict HSTS headers.

Authentication & Access Control

Flowmail supports multiple authentication methods:

Email OTP verification — No passwords to leak or phish
Passkey / WebAuthn — Hardware-backed authentication
Organization isolation — Complete data separation between teams

Every API request is authenticated and authorized. Rate limiting protects against brute-force attacks, and all sensitive actions are logged in an audit trail.

AI & Privacy

Our AI processing follows strict privacy principles:

Zero data training — Your emails are never used to train AI models
Minimal data retention — We only store the structured data you need
Processing transparency — You can see exactly what the AI extracted and confirm before any action is taken

Infrastructure

Flowmail runs on managed cloud infrastructure with:

Automatic backups and disaster recovery
DDoS protection at the network edge
Security headers (CSP, X-Frame-Options, X-Content-Type-Options)
Regular dependency updates and vulnerability scanning

Compliance

We maintain rigorous internal controls and transparent data handling:

GDPR Ready — Data minimization, right to erasure, data export, and DPA available upon request
Zero Data Training — Your email content is never used to train AI models
Full Audit Trail — Every sensitive operation is logged with actor, timestamp, and IP address
EU AI Act — Transparency and human oversight built into our AI pipeline
