Send Scheduled Messages

The user requires the ability to compose a message, save it as a draft, and then schedule it to be automatically sent at a specific future date and time. Once the scheduled time is reached, the system should ensure that the message is delivered reliably to one or more selected recipients simultaneously.

From a technical perspective, this feature involves:

• Draft management: Allowing users to save messages locally or on the server before they are finalized.

• Scheduling mechanism: Implementing a scheduling service or background job that triggers message dispatch at the exact time defined by the user.

• Message distribution: Ensuring that the scheduled message can be sent to either a single recipient or broadcast to multiple recipients in one execution.

• Reliability and consistency: Handling cases such as user being offline, server downtime, or network interruptions, so that the scheduled delivery is guaranteed once conditions allow.

This functionality would enhance user experience by enabling planned communication, reducing manual effort for time-sensitive messages, and supporting use cases such as reminders, announcements, or coordinated group messaging.
