This plugin offers a straightforward method to set up and configure the PHPMailer library included with the platform, enabling reliable email delivery through SMTP services. It is designed for developers and site administrators who need a dependable, code-driven approach to manage transactional and notification emails without a settings page.

• Pre-configured Service Drivers: Includes ready-to-use drivers for services like SendGrid, Mailtrap, and Mailhog. Each driver applies the recommended secure settings (like correct ports and encryption) so you don't have to research them.
• Configuration via Constants: All setup is done by defining PHP constants in your wp-config.php file. This keeps settings out of the database and under version control, suitable for development workflows.
• Extensible Driver System: You can create and register custom drivers for other SMTP services or unique configurations by implementing a simple interface and using a provided filter.
• No Admin Interface: The plugin deliberately avoids adding a settings page, promoting configuration as code. This ensures settings remain consistent across environments and are managed by developers.
• Leverages Core Library: It uses and configures the PHPMailer instance already bundled with the platform, avoiding the need to bundle a separate, potentially outdated version.
