SuprStack operates SuprSend, a notification infrastructure service for application teams. It coordinates messages across email, SMS, push, in-app inboxes and other channels through a unified API. Its workflow tools include batching, digests, channel routing, time-zone handling and notification preferences.
Teams can define customer-specific notification behaviour and manage in-app inbox experiences. It is relevant to developers and product teams coordinating transactional and product communication across multiple delivery providers and application interfaces.
