Compliance without friction
Automatic opt-out via STOP/AVSLUTA, quiet hours per market and content warnings that catch carrier-risk content before you send.
Your own Sender ID
Set any sender name you want, up to 11 alphanumeric characters. No pre-approval, no waiting, no follow-up questions. Change Sender ID between campaigns or use different IDs per segment for A/B testing.
No KYC or application
Other platforms force you through weeks of verification before the first SMS. We do not. Sign up, top up, send. That simple.
