This plugin adds a system for user-defined email subscriptions to any content on a website. It is designed for site owners who want to increase engagement by letting visitors choose exactly what updates they receive. When new or updated content matches a visitor's saved criteria, an automatic email notification is sent.

• Visitor-Controlled Subscriptions: Site visitors can create and manage their own alert subscriptions through simple forms or buttons, reducing administrative overhead.
• Granular Filtering: Subscriptions can be precisely defined using filters like category, author, keyword, and post status, ensuring highly relevant notifications.
• Automatic Email Alerts: The system automatically sends email confirmations for new subscriptions and delivers alerts when matching content is published or updated.
• Broad Application: Useful for various site types, including publishers keeping readers informed, online stores announcing product updates, and project sites ensuring stakeholders stay in the loop.
• Developer-Friendly Design: Built with extensibility in mind, offering hooks and filters for custom development work alongside straightforward user setup.
