Our prayers have finally been answered.
我們的愿望終于要成真了。

On Tuesday, Google announced an official "Undo Send" feature for all Gmail web accounts and the Inbox by Gmail app. The feature allows users to "take back" their emails within 30 seconds of sending them.
近日，谷歌宣布“撤回”功能正式應用于所有Gmail網絡賬號和Gmail應用軟件的收件箱。這個功能能夠讓使用者在發出郵件的三十秒內“撤回”郵件。

To activate the function, simply click onto Settings > General, and check the "Enable Undo Send" function. Then, you can choose whether to leave the function on for 5, 10, 20 or 30 seconds.
想要開啟這項功能，只要點擊設置>通用，選擇“允許撤回”功能。然后你能夠選擇5、10、20或者30秒內可以執行這項指令。?

After you send an email, a thin yellow strip appears under the search bar in your inbox, announcing that you've sent your email and giving you the option to undo or view your message. If you choose to undo the message -- within the given time frame of course -- your screen will bounce back to the original message, leaving you to delete or edit the message as you wish.
發送一封郵件之后，收件箱搜索欄的下方會出現一條黃色通知框，告訴你郵件已發出，可以選擇撤回或者瀏覽。如果你選擇撤回郵件——當然是在限定時間內——你的屏幕會跳轉到原始郵件的界面，你可以選擇刪除或者重新編輯。

Previously, the feature was available only to Gmail users who decided to enable the Labs function -- or, as Google says, "brave the Labs world." It's now a permanent Gmail function.
之前，這個功能僅應用于那些決定使用實驗室功能的人——或者，如谷歌所說，“勇戰實驗世界”的人。現在這成為了Gmail的永久功能。

The feature is available on most accounts that use Google Mail, but not yet all corporate accounts.
這項功能適用于谷歌郵箱的大多數賬號，但暫時不適用于公司賬號。
