Track every email you send — see opens, clicks and replies in real time
Security

An email platform you can trust.

The protection of your data and your recipients' data is our primary design consideration across all MailSeen infrastructure, products, and personnel operations.

Our principles

Built privacy-first.

These are the commitments we made before writing a single line of code.

Your email content stays private

MailSeen never reads, stores, or analyzes the content of any email you send or receive. Tracking works entirely through pixel load events — we have no access to your words, subjects, or attachments.

Minimal data collection

When a recipient opens a tracked email we record a timestamp, an approximate location derived from their IP (country and city only), and device type. We never store recipient email addresses.

GDPR compliant by design

Our infrastructure is hosted in the EU. We support the right to deletion, provide transparent disclosures, and never sell your data to third parties. Privacy is a product requirement, not an afterthought.

Encrypted in transit and at rest

All data is encrypted in transit with TLS 1.3 and at rest with AES-256. Access to production systems is restricted and requires two-factor authentication.

Transparency

Exactly what we store.

We believe you should know precisely what data exists about you and your recipients. Nothing in this table is vague by accident.
