開始使用

電子郵件標記會在電子郵件中使用結構化資料。Gmail 同時支援 JSON-LD微資料,兩者皆可用來在電子郵件中標記資訊。這麼做可讓 Google 瞭解欄位,並提供相關搜尋結果、動作和資訊卡。舉例來說,如果您的電子郵件與活動預訂有關,建議您為開始時間、場地、票券數量,以及用來定義該預訂的所有其他資訊加上註解。

您的第一個標記

假設您負責將 Google I/O 2013 票券發給參與者,並且想在這些電子郵件中使用標記語意資訊。票券確認電子郵件至少會包含下列 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>

標記這封電子郵件非常簡單。您可以在電子郵件 HTML 的 body 中的任何位置加入相關資訊,並使用同一種支援格式對應的結構化表單。下列程式碼區塊會顯示標記電子郵件的樣式:

JSON-LD

        }
      }
    }

上述電子郵件提供了用來定義活動預訂的最輕微資訊。你可以為電子郵件中的其他資訊加上標記,改善使用者體驗。舉例來說,FlightReservation 物件的 ticketToken 屬性可讓您新增條碼圖片 (例如 QR code),並加入登機證卡中。
