/**
 * Abstract class for an email notification.
 *
 * Do not rely on WordPress global variables or functions that rely on global variables such as `wp_get_current_user()`.
 * Email might be generated when no longer in scope. Instead, pass the values on as an argument when initiating the email
 * notification.
 *
 * Additionally, inside of plugins and themes, load email notification files based on this class inside the
 * `job_manager_email_init` hook. This will prevent unnecessary loading and won't include the files if this abstract
 * class isn't available.
 *
 * Example:
 * ```
 * add_action( 'job_manager_email_init', 'custom_plugin_include_emails' );
 * function custom_plugin_include_emails() {
 *     include_once 'emails/custom-plugin-sent-resume.php`;
 * }
 * ```
 *
 * @package wp-job-manager
 *
 * @since 1.31.0
