Security is a feature, not a tab.

We built Mailapp to handle the data you wouldn't hand to anyone else. This page is our standing answer to your security review.

Certifications

The compliance you'd expect, the evidence you can audit.

GDPR-aligned

EU-aligned data handling. DPA available without negotiation for any customer.

CCPA / CPRA

California consumer rights honoured globally by default.

No cardholder data

Mailapp never stores cardholder data. Payments processed by Stripe (PCI Level 1).

Residency

Your data, where you need it.

EU customers stay in the EU. Nothing crosses a border without your explicit consent.

Practices

How we operate, in plain English.

Encryption everywhere

TLS 1.3 in transit, AES-256 at rest. All keys rotated quarterly via AWS KMS. Customer-managed keys available on Enterprise.

Least-privilege access

Engineers don't access customer data by default. Every read is logged with a justification and routed to your dedicated audit log if you enable it.

Continuous monitoring

Anomaly detection on every privileged action. Alerts route to a 24/7 on-call rotation. Median mean-time-to-detect is under 6 minutes.

AI data governance

AI prompts never train shared models. Local model endpoints available for regulated industries. PII redaction is on by default.

Tenant isolation

Logical isolation by default, physical isolation available on Enterprise. Test data is segregated and purged on a 30-day cycle.

Incident response

Practiced quarterly via tabletop and game days. We publish post-mortems for any incident of severity 2 or higher.

Sub-processors

Every party with a chance to touch your data.

We notify on changes at least 30 days in advance. Customers can opt out of any change before it takes effect.
