What a read receipt does
A read receipt is a notification that tells you when someone has opened an email you sent them. When you request one, Outlook sends you a message back as soon as the recipient opens your email — not when they receive it, but when they actually read it.
Read receipts work in Outlook on the web, Outlook desktop for Windows and Mac, and Outlook mobile apps. They do not work with all email providers — if you send a read receipt request to a Gmail address or Yahoo address, the recipient may see a prompt asking permission to send the receipt, but they can decline. Some workplaces also disable read receipts on their email systems.
Key Takeaways
- A read receipt tells you when someone has opened an email you sent, not whether they have acted on it.
- In Outlook desktop, you request a read receipt by opening a new message, clicking Options, and checking "Request a Read Receipt."
- In Outlook on the web, you click the three dots in the compose window and select "Request a read receipt."
- Recipients can decline to send a read receipt, and some email systems block them entirely.
- Read receipts do not work reliably across different email providers like Gmail or Yahoo.
How to request a read receipt in Outlook desktop
Open Outlook and create a new email message. Type the recipient's address, subject line, and message body as you normally would. Then click the Options tab at the top of the compose window.
In the Options ribbon, look for the Tracking group. Click the checkbox next to "Request a Read Receipt." You will see a small checkmark appear. Now send the message as usual. When the recipient opens the email, Outlook will send you a notification message in your inbox saying they have read it.
If you want read receipts on every email you send, you can set this as a default. Go to File, then Options, then Mail. Scroll down to Tracking and check "For all messages, request a read receipt." After that, every email you send will automatically request one.
How to request a read receipt in Outlook on the web
Log into Outlook.com or your work Outlook account in a web browser. Click "New message" to start composing an email. Fill in the recipient, subject, and body text.
At the bottom right of the compose window, click the three dots (more options). A menu will appear. Select "Request a read receipt" — you will see a checkmark next to it when it is turned on. Send the message. The read receipt request is now active for that email.
How to request a read receipt in Outlook mobile
Open Outlook on your phone or tablet and tap the compose button to create a new message. Enter the recipient and your message text. Then look for a three-dot menu icon, usually at the top right of the compose window.
Tap the menu and look for an option labeled "Request read receipt" or "Tracking." Tap it to turn it on. The option may be worded differently depending on whether you are using iOS or Android, but the location is usually the same menu. Send your message when you are ready.
What happens when someone receives a read receipt request
When a recipient opens an email with a read receipt request, Outlook may show them a prompt asking if they want to send you a notification. On some systems, the prompt appears automatically. On others, the recipient has to actively choose to send the receipt or decline it.
Many people decline read receipts because they feel it is an invasion of privacy — the sender can see exactly when they opened the email. Some corporate email systems are set up to send receipts automatically without asking. If the recipient uses Gmail, Yahoo, or another non-Outlook email service, they may not see a prompt at all, and the receipt may not be sent back to you.
When read receipts do not work
Read receipts are not reliable across different email systems. If you send a read receipt request to someone with a Gmail account, they may see a message asking for permission, but Gmail does not have a built-in read receipt feature, so the process is clunky. Yahoo Mail has similar limitations.
Some workplaces disable read receipts on their email servers for privacy reasons. If your organization has done this, you will not be able to request them, and the option will be grayed out in your Outlook settings. Additionally, if the recipient has their email set to not send read receipts, you will not receive one even if you request it.
Mobile email clients that are not Outlook may also ignore read receipt requests. If someone is reading your email through Apple Mail, Thunderbird, or another third-party app, they may not see the request at all.
Alternatives to read receipts
If read receipts are not working for you, consider other ways to confirm someone has seen your message. You can ask the recipient to reply with a straightforward "got it" or "received." For important work emails, you can use Outlook's importance flag to mark a message as high priority, which draws attention to it without tracking when it is opened.
Some organizations use shared task management tools like Microsoft Teams or project management software where you can see when someone has viewed a message or task. These tools often provide better visibility than email read receipts and are less likely to feel intrusive to the recipient.
Frequently Asked Questions
Can I request a read receipt on an email I already sent?
No. You can only request a read receipt when you are composing a new message, before you send it. If you have already sent an email without requesting a receipt, you cannot go back and add one. You would need to send a follow-up email with a read receipt request.
Will I know who declined to send me a read receipt?
No. If someone declines to send a read receipt, you will not receive a notification about it. You will straightforward not get a receipt notification. You will not know whether they declined, their email system blocked it, or they have not opened the email yet.
Does a read receipt mean the person actually read the email?
Not necessarily. A read receipt only means the email was opened. The recipient could have opened it by accident, skimmed the subject line, or opened it without reading the full content. For important messages, a read receipt is a starting point, not proof that someone has understood or acted on your message.
Can I turn off read receipts so others cannot track when I open emails?
Yes. In Outlook desktop, go to File, Options, Mail, and uncheck "Allow requested read receipts to be sent." In Outlook on the web, go to Settings, Mail, and find the read receipt option. On mobile, the setting is usually in the app settings under Privacy or Tracking. Once you turn this off, Outlook will not send read receipts to anyone who requests them.
What is the difference between a read receipt and a delivery receipt?
A delivery receipt tells you when an email has reached the recipient's mail server — that it was successfully delivered. A read receipt tells you when the recipient actually opened the email. Delivery receipts are more reliable across different email systems, but they do not tell you whether anyone has actually read your message.
