Discover how Zend can transform the way your business operates
Zend is built for the messages your business can't afford to miss — across SMS, WhatsApp, email, and voice.
Here are the main ways teams put Zend to work, and the message types that fall under each.
1. OTP & verification
Prove it's really them. One-time passcodes and verification flows delivered over the channel your users already trust — with automatic fallback so codes still land.
- Sign-up verification codes
- Login 2FA codes
- Transaction confirmations
- Passwordless magic codes
- Phone-number verification
