A read receipt is an email notification delivered to you when a recipient opens an email you send. The receipt confirms that the recipient saw your message and records the time.
Unfortunately, there is not currently a feature in the web-based Google Mail application to set a read receipt to be sent with every message. Check with your desktop mail client (i.e. Outlook or Apple Mail) to utilize this feature.
Compose Message and Select "Request read receipt"
After composing your message,
- Click the arrow at the bottom-right corner of your composition box to reveal a drop-down menu.
- From the menu, select "Request read receipt."
Send the Message
This will send a read receipt request form to every recipient in the To: and Cc: boxes.
Status of Message
When you view a sent message for which you've requested a receipt, the current status appears just below the body of the message in the web-based Gmail client.
