You send out an important email, expecting to hear back quickly. But…time passes, and nothing. After a while, you start to wonder whether your recipient ever read the email? This will show you how to know.

The free version of Gmail does not include the return receipt feature. The feature is, however, available through GSuite. To use the return receipt feature in GSuite Gmail, you first must enable it.

To activate the return receipt feature, go the your GSuite Admin Console. Select Apps > GSuite > Settings for Gmail > Advanced settings. The Advanced Settings screen displays. Use the scroll bar on the right of the screen to scroll down to the Email Read Receipts option:


Click the toggle button to the left of Allow email read receipts to be sent to all addresses in my organization as well as the following email addresses. When this option is turned on, users in your organization can request and return email receipts.

Note: If you’re not the administrator of your GSuite, you’ll not be able to turn this feature on yourself. Ask your GSuite administrator to turn it on for you.

Once the Read Receipt capability is activated, simply type your email as usual. When you’ve finished, click the down arrow in the lower right corner to display a popup menu:

Click the Request read receipt option from the popup menu. When you’re ready, click the Send button to send your email as usual.
Below are the Gsuite and Gmail screen shots.
