Security and compliance
Protecting every message
Verification codes and notifications often carry account and personal details. From transport and storage to account access, we keep only what each step needs.
Encryption in transit
The API and console use HTTPS end to end.
Minimal data retention
Message content is kept only for the agreed period, then deleted automatically.
Account security
Reset API keys at any time and restrict access with IP allowlists.
Content compliance
We follow each destination country’s sending rules, and marketing messages support opt-out.
