Never miss a Google Calendar event, get a real phone call

Donotify is a notification enhancement service that converts Google Calendar events into automated voice calls delivered to users' phones. It addresses the limitations of standard digital notifications—such as silent pop-ups, suppression during Do Not Disturb or meeting modes, and device-specific delivery—by using telephony to ensure timely, high-attention reminders. The service is designed for professionals, remote workers, healthcare providers, educators, and anyone who relies on calendar-based scheduling but frequently misses critical events due to notification fatigue or environmental constraints.
The platform integrates directly with Google Calendar via OAuth, requires no installation of mobile apps, and operates independently of device settings. Users can begin with three free voice call reminders without providing payment information, and later upgrade to paid plans based on notification volume and team requirements.
Donotify operates in three primary stages: integration, configuration, and execution. First, users sign in via Google Sign-In and grant permission for calendar access; events are then synced automatically. Second, users select which calendar events require voice reminders and specify timing—either relative to the event (e.g., 5 minutes before) or at absolute times—and optionally configure fallback email reminders. Third, at the scheduled time, Donotify initiates an outbound phone call to the user’s registered number, delivering a synthesized voice announcement containing the event title, time, location, and description.
The system supports both recurring and one-time reminders, and allows users to define custom tasks outside their Google Calendar—such as medication alerts or follow-up deadlines—without requiring calendar entries. All voice calls are generated using text-to-speech technology and do not involve human agents or recordings.
Donotify improves reliability in time-sensitive contexts where missed notifications carry operational or personal consequences. Common applications include clinical appointment reminders for healthcare staff, student deadline alerts for academic coordinators, sales follow-up prompts for customer-facing teams, and caregiver task scheduling. Its ability to deliver reminders directly to a phone line—regardless of device lock state, app permissions, or network conditions—makes it especially valuable in environments with strict IT policies, low smartphone engagement, or high ambient noise.
The service also supports team use cases through its Professional plan, enabling shared calendars, role-based access, and analytics on reminder delivery success rates. For enterprise deployments, custom integrations and unlimited scalability are available under tailored agreements.
