What read receipts do and when to use them

A read receipt is a message Outlook sends back to you when someone opens an email you sent them. It is not a may provide that they read it carefully — only that they opened it. Outlook can request a read receipt when you send, and the recipient's Outlook can send one back automatically, ask them first, or ignore the request entirely.

Read receipts are useful when you need to know whether someone has seen a time-sensitive message — a meeting reschedule, a important date change, or a document you need feedback on. They are less useful for routine emails, because many people turn off read receipts to avoid constant notifications, and some organisations block them entirely. If someone does not send a read receipt back, it usually means they have not seen it yet, their settings prevent it, or their email system does not support it.

Read receipts also create a record that someone opened your message at a specific time, which can matter if you later need to prove you sent something. They do not, however, prove that the person understood it or acted on it.

Key Takeaways

  • To request a read receipt on a single email, open the message you are composing, select the three-dot menu, choose Message Options, and check "Request a Read Receipt".
  • To set read receipts as the default for all outgoing mail, go to File > Options > Mail > Tracking, and choose your preference for both sending and responding to read receipt requests.
  • When someone sends you a read receipt request, Outlook will either send one automatically, ask you first, or do nothing, depending on your settings.
  • Read receipts only confirm that an email was opened, not that it was read thoroughly or understood.
  • Many organisations and email systems do not support read receipts, so absence of a receipt does not mean the message was not delivered.

How to request a read receipt on a single email

Open a new message and write it as you normally would. Before you send, look for the three-dot menu (sometimes called "More Options" or the ellipsis button) in the toolbar at the top of the compose window. Click it.

Select Message Options from the dropdown. A panel will open on the right side of your screen. Look for the section labeled "Tracking" or "Delivery Options". Check the box next to "Request a Read Receipt". Then send the message as usual.

When the recipient opens the email, their Outlook will either send a read receipt automatically, prompt them to decide, or do nothing — depending on their own settings. If a receipt comes back, it will appear in your inbox as a separate message with a subject line like "Read: [Original Subject]". The message will include the date and time the email was opened.

How to set read receipts as your default

If you want Outlook to request read receipts on every email you send, you can set that as your default. Go to File in the top left, then select Options. In the left sidebar, click Mail.

Scroll down and find the section labeled Tracking. You will see two dropdown menus. The first one controls what you request from others: choose "Always send a read receipt request" if you want every outgoing email to request one. The second dropdown controls how Outlook handles read receipt requests from other people: you can choose to always send one back, never send one, or always ask before sending.

Most people choose "Ask before sending" for the second option, because it gives you control over each request. Once you have set your preferences, click OK to save.

What to do when someone requests a read receipt from you

When someone sends you an email with a read receipt request, what happens next depends on your settings. If your setting is "Always send", Outlook will send a receipt the moment you open the email, without asking. If your setting is "Ask before sending", a notification will pop up asking whether you want to send a receipt. If your setting is "Never send", Outlook will ignore the request and send nothing.

Sending a read receipt does not commit you to anything — it only tells the sender that you opened the message. You can open an email, send a receipt, and then take days to respond. The sender will know you saw it, but not what you plan to do about it.

If you are unsure whether to send a receipt, remember that it is just a notification. Sending one does not obligate you to act when ready. If you prefer privacy and do not want senders to know when you read their mail, set your preference to "Never send".

Why read receipts sometimes do not work

You may request a read receipt and never receive one, even though the email was delivered. This happens for several reasons. The recipient's email system may not support read receipts — many corporate email systems and some free email providers disable them. The recipient may have their settings turned off. Or the recipient's organisation may have a policy that blocks all read receipt requests.

If you do not receive a read receipt, it does not mean the email was not delivered or that the person ignored it. It usually means their system does not send them. If you need to know whether someone has seen your message, the safest approach is to ask them directly or wait for a response.

Some email systems also treat read receipts as a privacy concern, because they can be used to track when someone is reading mail. If someone declines to send you a read receipt, that is their choice, and it is worth respecting.

Read receipts versus delivery confirmation

Delivery confirmation and read receipts are different things. Delivery confirmation tells you that the email reached the recipient's mailbox. Read receipt tells you that the recipient opened it. Outlook provides delivery confirmation automatically for most emails — you can see it in your Sent folder. Read receipts require the recipient to send one back, so they are optional and often not available.

If you need to prove that an email was sent, delivery confirmation is usually enough. If you need to prove that someone saw it, you need a read receipt. If you need to prove that someone understood it or acted on it, neither one is sufficient — you will need a response or some other form of acknowledgment.

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 message. Once an email is in the recipient's inbox, you cannot add a read receipt request to it. You would need to send a new message with the request enabled.

Does requesting a read receipt slow down my email?

No. Read receipt requests do not affect how fast your email is sent or received. They are a small piece of metadata attached to the message, and they have no impact on delivery speed.

What if someone opens my email multiple times — do I get multiple read receipts?

Usually you get only one read receipt per email, sent the first time it is opened. If the recipient opens the same email again later, most email systems do not send another receipt. Some systems may behave differently, but one receipt per message is the standard.

Can I see if someone declined to send me a read receipt?

No. If someone does not send a read receipt, you will not receive a notification saying they declined. You will straightforward not receive a receipt. It is impossible to tell whether they opened the email and chose not to send one, or whether their system does not support read receipts at all.

Is it rude to request read receipts?

It depends on context. Requesting a read receipt for a time-sensitive work email is normal and expected. Requesting one for every casual message can feel intrusive to some people, because it tracks when they read mail. If you work in an environment where read receipts are standard, use them freely. If you are unsure, ask your team what is normal for your organisation.
