A notification is useful when it reaches the right person at the right time instead of turning a messenger into noise. I configure routing, priorities, deduplication, and acknowledgement for operational and user messages.

Scope includes event sources, templates, Telegram/MAX/VK channels, recipient rules, quiet hours, retries, and delivery logs. Acceptance ensures repeats do not cause storms, critical events bypass quiet hours only by rule, unavailable channels retry or fail over as agreed, and operators can see status. Absolute delivery cannot be promised when a platform or user blocks the bot.
