Users can create unlimited dynamic groups, from one contact to thousands, then send messages immediately or schedule them. Real-time reports show who received a message and when. For automated calls, typed text can be converted into voice messages, and senders can use a saved audio library. Text recipients can reply, with responses trackable in the mobile app. The service is available on Android, iOS and the web, and its mobile app is designed for authorized senders.
