Automatic opt-out via STOP/AVSLUTA, quiet hours per market and content warnings that catch carrier-risk content before you send.
GDPR-safe
Data is stored in the EU, with no subprocessors outside the EEA without explicit consent. A DPA is available on request and opt-out is handled automatically.
Frequently asked questions
How is opt-out handled?
Automatically through STOP/AVSLUTA — the customer is placed on a per-sender blocklist. You can also whitelist.
Can I schedule campaigns?
Yes. From the dashboard or API, including timezone-aware scheduling and batch sends.
Can I use multiple Sender IDs at once?
Yes. Rotate per segment, campaign or language with no hard cap.
Can I choose any Sender ID?
Yes. Set any sender name you want, up to 11 characters. We do not pre-review Sender IDs for you.
Do I need KYC or verification?
No. Sign up, top up and send. No forms, no application, no waiting.
Is SMS content logged?
Metadata is logged for DLR and support. Message content can be pseudonymized or deleted on request.
