What it shows

  • User preferences and frequency caps filter alerts before queueing.
  • Isolated priority queues protect critical 2FA codes from bulk promotions.
  • Worker pools feature automated failover between multiple delivery vendors.

The takeaway

Isolate notification tiers into priority queues and decouple vendor integrations.
