This extension for a popular notification plugin allows you to automate and delay the sending of messages based on a calendar. It is designed for site administrators and developers who need to create timed communication workflows without manual intervention.

Time-based Scheduling: Set notifications to send at an absolute date and time, or use relative timing like '3 days before' a date stored in a custom field.

Flexible Triggers: Configure schedules using post metadata, Advanced Custom Fields, or other merge tags to create dynamic, data-driven notification scenarios.

Integration Ready: Works with the plugin's existing library of carriers (like email, Slack, and Twilio) and combines with other extensions, such as for WooCommerce orders, to build advanced automations.

Object Locking: Prevents duplicate notifications by locking the data object once a scheduled notification for it is in the processing queue.

Time Windows: Adds a configurable window for sending, providing control over the delivery timeframe for time-sensitive messages.
