 Key Features:
 
-- Flexible Scheduling: Supports Delayed, Interval, and Cron schedules, offering diverse transmission options.
-- Reliable Delivery: Ensures messages reach their destination through robust transmission adapters like Nats.
-- Data Integrity: Secures message data during transmission and storage with configurable adapters like in-memory and Postgres.
-- Adaptable Deployment: Runs as a standalone binary, Docker container, or Kubernetes microservice, catering to different needs.
-- Comprehensive Configuration: Provides a dedicated algebraic data structure as configuration for easy setup and customization.
-- Detailed Monitoring: Integrates with Prometheus metrics for insights into program behaviour and performance.
+- Flexible Scheduling: Supports Delayed, Interval, and Cron schedules, with provided number of iterations.
+- Reliable Delivery: Ensures messages reach their destination through robust transmission adapters with fault-tolerant exactly-once delivery.
+- Data Integrity: Secures message data during transmission and storage with configurable adapters appropriate for its deployment environment, like in-memory and Postgres.
+- Adaptable Deployment: Runs as a standalone binary, Docker container, or Kubernetes microservice.
+- Comprehensive Configuration: Provides a dedicated algebraic data structure for correct configuration.
+- Observability: Integrates with Prometheus metrics for insights into program behaviour and performance.
 - Health Checks: Implements the [gRPC Health Checking Protocol](https://github.com/grpc/grpc/blob/master/doc/health-checking.md) for monitoring service health.
 - Graceful Shutdown: Handles termination signals (SIGINT, SIGTERM) for proper program closure.
-- Rigorous Testing: Emphasizes thorough testing practices to ensure reliability and stability.
