    Every message matters

    Zello makes sure every message gets where it needs to go. No excuses.

    • Delivery confirmation

      Receive visual delivery confirmation so you know your message has been received.

    • Offline messaging

      If connectivity is ever lost, messages in the queue can be sent automatically the moment it’s restored.

    • Missed message notifications

      When you’re reaching out one-to-one to a user who’s offline, Zello sends a notification once they’re back online letting them know they have a message waiting.

    • Shared dispatch call queue

      Zello’s Dispatch Hub eliminates missed calls by routing them to all available dispatchers and keeping their queue organized.
