开始使用

电子邮件标记使用电子邮件中的结构化数据来发挥作用。Gmail 同时支持 JSON-LDMicrodata,您可以使用其中任意一种对电子邮件中的信息进行标记。这样,Google 就能了解这些字段并向用户提供相关的搜索结果、操作和卡片。例如,如果电子邮件是关于活动预订的,您可能需要为开始时间、场地、门票数量以及定义此预订的所有其他信息添加注释。

您的第一个标记

假设您负责向参与者发送 2013 年 Google I/O 大会的门票,并希望在这些电子邮件中使用标记语义信息。您的门票确认电子邮件至少应包含以下 HTML:

<html>
  <body>
    <p>
      Dear John, thanks for booking your Google I/O ticket with us.
    </p>
    <p>
      BOOKING DETAILS<br/>
      Order for: John Smith<br/>
      Event: Google I/O 2013<br/>
      When: May 15th 2013 8:30am PST<br/>
      Venue: Moscone Center, 800 Howard St., San Francisco, CA 94103<br/>
      Reservation number: IO12345<br/>
    </p>
  </body>
</html>

标记此电子邮件十分简单。电子邮件正文中的相关信息可以采用与其中一种支持的格式对应的结构化形式,添加到电子邮件 HTML 的 body 中的任意位置。以下代码块显示了已标记的电子邮件:
