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 turn on read receipts in Outlook, the person who receives your message gets a prompt asking whether they want to let you know they've read it. If they say yes, Outlook sends you back a message confirming the date and time they opened your email.
Read receipts are not the same as delivery receipts. A delivery receipt tells you the email reached the recipient's mailbox. A read receipt tells you they actually opened and read the message — or at least opened it long enough for Outlook to register the action.
One important thing to know: read receipts only work if the person on the other end is also using Outlook or a compatible email client, and they have to choose to send the receipt back. Many people decline read receipt requests, either because they don't want to confirm they've read something, or because their email settings block them automatically.
Key Takeaways
- Read receipts in Outlook require the recipient to confirm they've opened your email, and many people decline or have them blocked.
- You can request a read receipt for a single email when you send it, or set Outlook to request them for all outgoing messages.
- The steps differ depending on whether you use Outlook on the web, Outlook desktop for Windows, or Outlook for Mac.
- Read receipts only work reliably between Outlook users or users of compatible email systems; Gmail and other providers may not support them.
How to request a read receipt on one email in Outlook desktop
If you use Outlook on your Windows computer, open a new email or reply you're composing. Look for the Options tab at the top of the compose window. Click it, then look for a button labeled Request a Read Receipt or Request Read Receipt — the exact wording depends on your Outlook version. Click that button, then send your email as normal.
When the recipient opens the email, they'll see a dialog box asking if they want to send you a read receipt. If they click yes, you'll receive a notification in your inbox confirming they read it. If they click no or close the dialog, you won't get a notification.
How to request read receipts for all emails in Outlook desktop
If you want Outlook to request a read receipt on every email you send, you can set this as a default. Click File at the top left, then Options. In the Options window, click Mail on the left side. Scroll down until you find a section called Tracking.
In the Tracking section, check the box next to Request a read receipt for all messages I send. Click OK to save. From that point forward, every email you send will include a read receipt request — though recipients can still decline.
Be aware that requesting read receipts on every message can annoy some recipients, especially in professional settings where people prefer not to confirm they've read something. You might want to use this setting only if you have a specific reason to track opens, like confirming that important time-sensitive messages reached the right people.
How to request read receipts in Outlook on the web
If you use Outlook through a web browser (outlook.com or your organization's web version), the process is slightly different. Compose a new email, then look for three dots or a menu icon near the send button — usually in the bottom right of the compose area. Click it and look for an option labeled Request Read Receipt or Request a read receipt. Click that option, then send your email.
Outlook on the web does not have a setting to request read receipts for all messages by default. You'll need to request them one email at a time.
How to request read receipts in Outlook for Mac
On a Mac, open a new email or reply. Look for the Options button in the toolbar at the top of the compose window. Click it, then find and click Request Read Receipt. Send your email as normal.
To set read receipts as a default for all emails on Mac, click Outlook in the menu bar at the very top, then Preferences. Click Mail, then look for Sending Options or Tracking. Check the box for requesting read receipts, then close the window.
Why read receipts often don't work the way you expect
Read receipts have real limits. If the recipient uses Gmail, Yahoo Mail, or many other email providers, they may not see the read receipt request at all, or their system may not be able to send one back. Even if both people use Outlook, the recipient's email administrator might have disabled read receipts on their account for privacy reasons.
Some people also have their email client set to automatically decline all read receipt requests, or they manually decline them every time. There's no way to know in advance whether someone will send you a read receipt, so you can't rely on them as proof that someone actually read your message.
If you need to know whether someone received and read an important email, the most reliable approach is to ask them directly or use a different method of communication — like a phone call or a message through your organization's internal chat system — to confirm they got it.
Frequently Asked Questions
Does a read receipt mean someone actually read the whole email?
No. A read receipt only confirms that someone opened the email. They might have opened it, glanced at the first line, and closed it. Outlook registers it as read either way. Some email clients also mark messages as read automatically without the person actually looking at them.
Can I see if someone declined my read receipt request?
No. If someone declines or ignores a read receipt request, you straightforward won't receive a notification. You have no way to know whether they declined it, their email system doesn't support it, or they never saw the request at all.
What happens if I request a read receipt from someone using Gmail?
Gmail does not support read receipts in the traditional sense. The recipient won't see a prompt asking to send you a read receipt, and you won't receive one. Some third-party tools claim to track Gmail opens, but they work differently and are not built into Gmail itself.
Can I turn off read receipts so others can't track when I open emails?
Yes. In Outlook desktop, click File, then Options, then Mail, then look for Tracking. Uncheck the box that says Process requests for read receipts on messages I receive. You can also choose to always decline read receipt requests without being asked each time.
Is there a difference between read receipts and delivery receipts?
Yes. A delivery receipt confirms your email reached the recipient's mail server. A read receipt confirms they opened it. Delivery receipts are more reliable because they're generated automatically by the mail server. Read receipts depend on the recipient's choice and their email system's support.
