电子邮件通知

本页介绍如何使用 Amazon Web Services Management Console、 Amazon SDK for Java或为电子邮件地址订阅 Amazon SNS 主题。 Amazon SDK for .NET

注意事项
  • 您无法自定义电子邮件消息的正文。电子邮件传输功能旨在提供内部系统提示,而不是营销消息。

  • 仅标准主题支持直接订阅电子邮件端点。

  • 电子邮件传输吞吐量根据 Amazon SNS 配额进行限制。

重要

要防止邮件列表接收人取消订阅来自 Amazon SNS 主题电子邮件的所有接收人,请参阅设置需要身份验证才能从 Amazon 支持取消订阅的电子邮件订阅

要使用电子邮件地址订阅 Amazon SNS 主题 Amazon Web Services Management Console

  1. 登录 Amazon SNS 控制台

  2. 在左侧导航窗格中,选择订阅

  3. Subscriptions(订阅)页面上,选择 Create subscription(创建订阅)。

  4. Create subscription(创建订阅)页上的 Details(详细信息)部分中,执行以下操作:

    1. 对于 Topic ARN(主题 ARN),选择主题的 Amazon Resource Name (ARN)。

    2. 对于协议,选择电子邮件

    3. 对于 Endpoint(终端节点),输入电子邮件地址。

    4. (可选)要配置筛选策略,请展开 Subscription filter policy(订阅筛选策略)部分。有关更多信息,请参阅 Amazon SNS 订阅筛选策略

    5. (可选)要启用基于有效负载的筛选,请将 Filter Policy Scope 配置为 MessageBody。有关更多信息,请参阅 Amazon SNS 订阅筛选策略范围

    6. (可选)要为订阅配置死信队列,请展开 Redrive policy (dead-letter queue)(重新驱动策略(死信队列))部分。有关更多信息,请参阅 Amazon SNS 死信队列 (DLQ)

    7. 选择创建订阅

      控制台将创建订阅并打开订阅的 Details(详细信息)页面。

您必须先确认订阅,然后才能开始接收消息。

要确认订阅
  1. 检查您的电子邮件收件箱,然后从 Amazon SNS 中的电子邮件中选择 Confirm subscription(确认订阅)。

  2. Amazon SNS 会打开您的 Web 浏览器,并显示带有您的订阅 ID 的订阅确认信息。
