What a read receipt does and when to use it
A read receipt is a message Outlook sends back to the person who emailed you, telling them you opened their message. When you turn on read receipts for an email, the sender gets a notification — usually a popup or a message in their inbox — confirming that you read what they sent.
Read receipts are useful when you need proof that someone saw your message, especially for time-sensitive requests or important decisions. They are not the same as delivery receipts, which only confirm that an email reached the recipient's mailbox, not that they opened it.
One thing to know: read receipts only work if the person receiving your email has them turned on in their settings. If they have disabled read receipts, you will not get a notification even if they open your message. Also, some email systems block read receipt requests for privacy reasons.
Key Takeaways
- You can request a read receipt for a single email by checking the "Request a Read Receipt" box before you send it.
- To turn on read receipts for all your outgoing emails, go to File > Options > Mail > Tracking and select "Always send a read receipt."
- Read receipts only notify you if the recipient has them enabled — many people turn them off for privacy.
- The recipient will see a prompt asking whether to send you a read receipt when they open your message.
How to request a read receipt for a single email
The quickest way to get a read receipt is to turn it on just for one message. Open a new email and write your message as usual. Before you click Send, look for the tracking options in your ribbon.
In Outlook on Windows, click the Options tab at the top of the compose window. You will see a checkbox labeled "Request a Read Receipt." Check that box, then send the email normally. In Outlook on Mac, click the three dots (more options) in the compose window, then select "Request Read Receipt" and send.
When the recipient opens your email, they will see a dialog asking if they want to send you a read receipt. If they click yes, you will get a notification in your inbox. If they click no or dismiss the prompt, you will not hear back — and you will have no way of knowing whether they actually read the message.
How to turn on read receipts for all your emails
If you want every email you send to request a read receipt automatically, you can set this as your default. On Windows, click File in the top left, then Options, then Mail from the left sidebar. Scroll down to the "Tracking" section.
You will see two checkboxes: "Request a Read Receipt for All Messages I Send" and "Request a Delivery Receipt for All Messages I Send." Check the first one if you want read receipts for everything going forward. Click OK to save your changes.
On Mac, click Outlook in the top menu, then Preferences, then Mail, then Composing. Look for the "Requesting Read Receipts" dropdown and select "Always." This will explore to all new emails you send from that point on.
What happens when someone receives your read receipt request
When a recipient opens an email with a read receipt request, Outlook shows them a notification at the top of the message. The notification usually says something like "The sender of this message has requested a read receipt when you read this email." Below that are two buttons: "Send a Read Receipt" and "Do Not Send."
If they click "Send a Read Receipt," a message goes back to you confirming they opened the email. If they click "Do Not Send" or straightforward close the notification, you will not get any confirmation. Many people disable read receipts in their settings because they find them intrusive or prefer not to share that information.
Why you might not receive a read receipt even if someone opens your email
The most common reason is that the recipient has read receipts turned off. Some people disable them for privacy — they do not want senders to know exactly when they read messages. Others work in organizations where read receipts are blocked by the email administrator.
Another reason is that the recipient uses a different email client, like Gmail or Apple Mail, which may not support Outlook's read receipt system. Web-based versions of Outlook sometimes handle read receipts differently than the desktop app. If you need to know whether someone saw your message and they do not send a receipt, you may need to follow up with a phone call or a separate message asking them to confirm.
How to check if you have received read receipts
When someone sends you a read receipt, it arrives as a message in your inbox. The subject line usually says something like "Read: [Original Subject Line]." Open it like any other email to see the timestamp showing when the person opened your original message.
You can also check your Sent folder to see which emails have received read receipts. In Outlook on Windows, click on an email in your Sent folder, then look at the Details pane on the right side. If a read receipt has been received, you will see a note saying "Read: [Date and Time]." On Mac, right-click the email in your Sent folder and select "Message Status" to see read receipt information.
Turning off read receipts if you receive too many requests
If you find that read receipt requests are annoying or you prefer not to share when you read emails, you can disable them. On Windows, go to File > Options > Mail and scroll to the Tracking section. Uncheck "Request a Read Receipt for All Messages I Send" if you had it on. You can also change how Outlook handles incoming read receipt requests by selecting "Never Send a Read Receipt" from the dropdown menu in that same section.
On Mac, go to Outlook > Preferences > Mail > Composing and change the "Requesting Read Receipts" dropdown to "Never." You can also set it to "Ask Me" if you want to decide on a case-by-case basis whether to send a receipt for each incoming email.
Frequently Asked Questions
Can I see if someone read my email without requesting a read receipt?
No, not through Outlook's built-in tools. You need to request a read receipt before you send the email. If you forgot to request one, you cannot go back and add it to an email already in the recipient's inbox. You would have to send a new email with the read receipt option turned on.
What if I request a read receipt and the person says they did not get the notification?
Read receipt notifications sometimes get buried or dismissed without the person noticing. They may have clicked "Do Not Send" by accident or their email client may have hidden the prompt. The best approach is to ask them directly to confirm they received and read your message, rather than relying on the read receipt system.
Do read receipts work if I send an email to someone outside my organization?
They can, but it depends on the recipient's email system and their settings. If they use Outlook and have read receipts enabled, you will get a notification. If they use Gmail, Apple Mail, or another email client, the read receipt may not work even if they open your message. Some organizations also block read receipt requests for security reasons.
Can I request a read receipt for an email I already sent?
No, you cannot add a read receipt request to an email that is already in someone's inbox. You can only request a read receipt before you send an email. If you need to know whether someone read a previous message, you will have to send a follow-up email with the read receipt option turned on.
Will the recipient know I requested a read receipt?
Yes, they will see a notification when they open your email telling them that you requested a read receipt. They will know you want to be notified when they read the message, and they can choose whether or not to send you that confirmation.
