What read receipts do and when to use them
A read receipt is a notification that tells you when someone has opened an email you sent them. When you turn on read receipts for a message, Outlook asks the recipient's email client to send you a confirmation — it does not track whether they actually read the content, only that they opened it.
Read receipts work best for time-sensitive messages where you need to know if someone has seen your email. They are less useful for casual messages or group emails, because not every email client honors the request, and some recipients disable read receipts on their end. Outlook respects read receipt requests from other senders, but you control whether to send them back.
The feature is separate from account security — it does not protect your account or prevent hackers from accessing your messages. It is purely a communication tool to confirm delivery and viewing.
Key Takeaways
- You can request a read receipt on individual emails in Outlook by opening the message options and checking the "Request a Read Receipt" box before sending.
- Read receipts only work if the recipient's email client supports them and they have not disabled the feature in their own settings.
- Outlook on the web, Outlook desktop, and Outlook mobile all support read receipts, but the steps differ slightly between each version.
- When you receive a read receipt request, Outlook will ask you whether to send a confirmation — you can choose to send it, not send it, or set a default preference.
How to request a read receipt in Outlook on the web
In Outlook on the web, open a new email and compose your message. Before you send, look for the three dots menu (often called "More options" or "..." button) near the Send button at the bottom of the compose window. Click it to expand additional settings.
In the menu that appears, find and click "Request a read receipt" or "Request delivery and read receipts" — the exact wording depends on your Outlook version. A checkmark will appear next to the option once it is selected. Then send your email normally. The recipient will see a notification asking whether to send you a read receipt.
If you do not see this option, your organization may have disabled read receipts at the account level. Contact your email administrator to confirm whether the feature is available to you.
How to request a read receipt in Outlook desktop
In Outlook for Windows or Mac, create a new email and write your message. Before sending, click the "Options" tab at the top of the compose window (on Windows) or look for "Message" in the menu bar (on Mac).
On Windows, the Options tab will show a "Request a Read Receipt" checkbox on the right side of the ribbon. Check the box, then send your email. On Mac, click the "Tracking" button in the Message menu, then check "Request Read Receipt" and send.
If you use Outlook frequently and want read receipts on most emails, you can set this as a default. In Outlook for Windows, go to File > Options > Mail, scroll to Tracking, and check "Always request a read receipt". On Mac, open Outlook > Preferences > General, find "Tracking", and check the same option.
How to request a read receipt in Outlook mobile
In Outlook for iPhone or Android, compose a new email. Tap the three dots menu at the top right of the compose screen. Scroll down and look for "Request Read Receipt" or "Tracking" — the label varies by phone and app version.
Tap the option to enable it, then send your email. The feature works the same way as on desktop: the recipient will be asked whether to send you a read receipt. Note that some mobile email clients do not support read receipts, so the recipient may not receive the request even if they have Outlook installed.
What happens when someone receives your read receipt request
When you send an email with a read receipt request, the recipient's Outlook will display a notification asking "The sender of this message has requested a read receipt. Do you want to send a read receipt?" They can choose to send it, not send it, or set a preference to always or never send receipts.
If they send the receipt, you will receive an email notification that says the message was opened, along with the date and time. If they decline or their email client does not support read receipts, you will not receive a notification — Outlook does not tell you which happened.
Some recipients may feel that read receipts are intrusive or a privacy concern. It is worth considering whether you actually need the confirmation before requesting it, especially for emails to people outside your organization.
How to respond to read receipt requests you receive
When someone sends you an email with a read receipt request, Outlook will prompt you when you open the message. You can click "Send Read Receipt" to confirm you have opened it, or "Do Not Send" to decline.
If you want to set a default behavior instead of answering each time, you can configure this in your settings. In Outlook on the web, go to Settings > Mail > Message Handling and look for the read receipt option. In Outlook desktop on Windows, go to File > Options > Mail > Tracking and choose your preference. On Mac, open Outlook > Preferences > General > Tracking.
Why read receipts may not work
Read receipts depend on the recipient's email client supporting the feature and having it enabled. Gmail, Yahoo Mail, and some corporate email systems do not honor read receipt requests, so you will not receive a confirmation even if the recipient opens your email. Outlook-to-Outlook messages are most reliable.
Some recipients disable read receipts in their settings because they prefer privacy. Others use email clients that strip out the read receipt request before it reaches them. If you do not receive a read receipt, it does not necessarily mean the person has not read your email — it may straightforward mean their system does not support it.
For critical messages where you need confirmation, consider following up with a phone call or a separate message asking for acknowledgment. Read receipts are a convenience, not a may provide.
Frequently Asked Questions
Can I request a read receipt on an email I already sent?
No. Read receipt requests must be set before you send the email. Once an email is in the recipient's inbox, you cannot add a read receipt request retroactively. If you need confirmation on a message you already sent, you will have to send a follow-up email with the read receipt option enabled.
Does requesting a read receipt affect email security?
No. Read receipts are a separate feature from account security and do not make your email more or less find. They do not protect against hackers or prevent unauthorized access to your account. If you are concerned about account security, focus on strong passwords and two-factor authentication instead.
Will the recipient know I requested a read receipt?
Yes. Outlook will notify them that you requested a read receipt when they open the email. They will see a prompt asking whether to send one back. This is by design — read receipts are transparent, not hidden.
What if my organization has disabled read receipts?
Some companies turn off read receipts at the account level for privacy or policy reasons. If you do not see the read receipt option in your settings, contact your IT department or email administrator. They can tell you whether the feature is available and may be able to enable it for you.
Can I use read receipts to track whether someone is ignoring my emails?
Not reliably. A read receipt only confirms that someone opened your email, not that they read it, understood it, or will act on it. Many people open emails without reading them fully. If you need a response, ask for one directly in your message rather than relying on read receipts.
