+# Email | 邮件
+提供一套通用 Service 用于定制需求，和一套现成的事件/监听器用于异步发送。
+
+## 服务类
+[\Singularity\HDK\Core\Service\EmailService](../src/Service/EmailService.php)
+* 发送纯文本邮件的 `\Singularity\HDK\Core\Service\EmailService::sendText()`
+* 发送 Html 富文本邮件的 `\Singularity\HDK\Core\Service\EmailService::sendHtml()` 
+
+## 事件机制
+> 这种方式无法监听邮件发送的结果！
+> 
+> 如果你需要根据邮件发送的结果进行处理，
+> 请使用服务类进行自定义
+
+更好的方法可能是在事件发生后触发异步队列，
+但如果将异步队列封装在本包中，
+相当于强制引用本库的项目使用异步队列机制，
+这是我们不愿意看到的。
+所以这里的监听器只是集成了同步发送的操作。
+
+如果你想要定义更好的设计，
+你可以直接使用提供的 Service 类进行定制。 
+> 或许这里还有优化空间😄
+
+### 事件
+[\Singularity\HDK\Core\Events\EmailWillSent](../src/Events/EmailWillSent.php)
+### 监听器
+[\Singularity\HDK\Core\Listener\EmailWillSentListener](../src/Listener/EmailWillSentListener.php)
+### 使用方法
+监听器已经通过 [ConfigProvider](../src/ConfigProvider.php) 机制注册，
+所以你只需要在要发送邮件的地方调度这个事件即可。
+> 这也就意味着，你无法调用这个事件，但不触发这个监听器。
+> 如果你有这样做的必要，请创建一个自己的事件。
+> 这也是为了保证功能的完整性和原子性。
+
+具体使用方法，如下代码所示：
+
+```php
+<?php
+namespace App\Service;
+
+use Hyperf\Di\Annotation\Inject;
+use Psr\EventDispatcher\EventDispatcherInterface;
+use App\Event\UserRegistered;use Singularity\HDK\Core\Events\EmailWillSent; 
+
+class UserService
+{
+    /**
+     * @var EventDispatcherInterface
+     */
+    #[Inject]
+    private $eventDispatcher;
+    
+    public function register()
+    {
+        // 我们假设存在 User 这个实体
+        $user = new User();
+        $result = $user->save();
+        
+        // ↓
+        // 这里 dispatch(object $event) 会逐个运行监听该事件的监听器
+        $this->eventDispatcher->dispatch(new EmailWillSent(
+            target: $user->mobile,
+            subject: '注册成功通知',
+            type: 'html', // 默认 text 可以不传
+            content: <<<HTML
+<h1>恭喜你，注册成功！</h1>
+HTML,
+        ));
+        // ↑
+        
+        return $result;
+    }
+}
+
+```
