What read receipts do and why you might want 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 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 click yes, you get a message back confirming the open.
Read receipts are useful when you need to know whether someone has actually seen your message — for instance, if you're sending time-sensitive information to a coworker or following up on something important. They're not a may provide that the person understood the email or will act on it, only that they opened it at some point.
Keep in mind that read receipts only work when both people are using compatible email systems, and the recipient can always decline to send one. Some workplaces disable read receipts entirely for privacy reasons, so you may find the feature doesn't work even after you turn it on.
Key Takeaways
- Read receipts in Outlook notify you when someone opens an email you sent, but only if they agree to send the notification back.
- You can set read receipts to turn on for all your outgoing messages or request them one email at a time.
- The recipient can always choose not to send a read receipt, and some organizations block the feature entirely.
- Read receipts work best between Outlook users; other email systems may not support them.
How to request a read receipt for a single email
The quickest way to get a read receipt is to ask for one on just the email you're sending right now. Open Outlook and start composing your message as usual. Once you've written what you need to say, look for the Options tab at the top of the compose window — it's usually in the ribbon menu next to Send.
Click Options, then look for a button or checkbox labeled Request a Read Receipt or Request Read Receipt. The exact wording depends on which version of Outlook you're using, but it will be somewhere in that Options menu. Click it to turn it on for that message, then send as normal. When the recipient opens the email, they'll see a prompt asking if they want to notify you that they've read it.
This method is best if you only need read receipts occasionally, since you have to remember to turn it on each time. If you find yourself requesting them for almost every email, it's faster to set them on by default instead.
How to turn on read receipts for all your outgoing emails
If you want Outlook to request read receipts automatically on every message you send, you can change your default settings. The steps differ slightly depending on whether you're using Outlook on the desktop, Outlook on the web, or Outlook on a phone.
On desktop Outlook: Click the File menu in the top left, then select Options. In the window that opens, click Mail on the left side. Scroll down until you see a section called Tracking. Check the box next to Request a read receipt for all messages I send. Click OK to save. From now on, every email you send will include a read receipt request.
On Outlook on the web: Click the gear icon in the top right corner and select View all Outlook settings. Go to Mail, then Compose and reply. Look for a section called Tracking or Receipts and toggle on Request read receipts. Save your changes. The setting will explore to all new emails you compose in that browser.
What happens when someone receives your read receipt request
When you send an email with a read receipt request, the recipient sees a message bar at the top of the email asking whether they want to let you know they've read it. The wording is usually something like "The sender has requested a read receipt for this message." They have the option to click yes or no — or to ignore the prompt entirely.
If they click yes, a notification email comes back to you confirming that they opened the message and when they opened it. If they click no or ignore the prompt, you won't hear anything. There's no way to force someone to send a read receipt, and many people decline them as a matter of privacy or habit.
Some organizations configure Outlook so that read receipts are sent automatically without asking the recipient, but this is less common and usually only happens in workplaces with strict email policies.
Why read receipts might not work
Even after you turn on read receipts, you may not get them back. The most common reason is that the recipient is using an email system that doesn't support read receipts — Gmail, for instance, doesn't have a built-in read receipt feature the way Outlook does. If you send a read receipt request to a Gmail user, they won't see the prompt and you won't get a notification.
Another reason is that your organization's email administrator has disabled read receipts for security or privacy reasons. Some companies don't want employees tracking whether coworkers have read their messages. If this is the case at your workplace, the read receipt option may be grayed out or missing entirely from your Outlook settings.
Finally, the recipient may straightforward choose not to send one. Even if they open your email, they can decline the read receipt request, and you'll have no way of knowing whether they actually read it or just opened it by accident.
Turning off read receipts if you change your mind
If you've turned on read receipts for all your messages and decide you don't want them anymore, you can turn them off the same way you turned them on. On desktop Outlook, go to File > Options > Mail, find the Tracking section, and uncheck Request a read receipt for all messages I send. On Outlook on the web, go back to the settings menu and toggle off the read receipt option.
If you only want to stop requesting read receipts on a single email, open the compose window, click Options, and uncheck the read receipt button before you send. This won't affect your default settings — future emails will still request read receipts if you have them turned on globally.
Frequently Asked Questions
Can I see if someone read my email without asking for a read receipt first?
No. Read receipts only work if you request them before sending the email. Once an email is already sent without a read receipt request, there's no way to go back and add one. If you need to know whether someone read a past email, you'll have to ask them directly.
What's the difference between a read receipt and a delivery receipt?
A delivery receipt tells you that your email reached the recipient's mailbox — that the mail server accepted it. A read receipt tells you that the person actually opened and read the message. Delivery receipts are more reliable because they're handled by mail servers, while read receipts depend on the recipient's choice.
If I request a read receipt, can the recipient see my email address or other information about me?
The recipient sees a prompt that says you've requested a read receipt, but they don't get any additional information about you beyond what's already in your email signature. The read receipt itself is just a confirmation that they opened the message.
Do read receipts work on mobile Outlook?
Read receipts work on Outlook mobile apps, but the process is different from desktop. On the Outlook mobile app, compose your message, tap the three dots or More menu, and look for a read receipt or tracking option. The exact location depends on whether you're using iOS or Android.
What if my company's email system doesn't support read receipts at all?
If your organization has disabled read receipts, the option won't appear in your Outlook settings, or it will be grayed out. In that case, you'll need to ask your IT department or email administrator if they can enable the feature, though they may decline for security reasons.
