# Best Notification Infrastructure Software - Page 2

  *By [Adam Crivello](https://research.g2.com/insights/author/adam-crivello)*

   Notification infrastructure is the complete technological framework and systems that deliver user notifications, alerts, and messages. It includes the hardware, software, and network components that deliver messages through various channels such as email, SMS, and push notifications.

Instead of relying on traditional development tools, notification infrastructure allows users to edit the product itself, often utilizing a drag-and-drop format. By adopting this format, the development process for notification applications becomes more scalable and less time consuming for developers. This differs these products from [push notification software](https://www.g2.com/categories/push-notification), as they are more scalable and typically have a more reliable delivery system.

To qualify for inclusion in the Notification Infrastructure category, a product must:

- Include multichannel and multi-product API integration (SMS, email, push, WhatsApp)
- Allow users to build out workflow automation across channels
- Feature template engines and template repositories
- Provide users the option to customize notification setting
- Centralize app where all notifications are streamlined
