What a read receipt does and why you might want one

A read receipt is a notification that tells you when someone opens an email you sent them. When you turn on read receipts for a message, Outlook sends you an automatic reply the moment the recipient opens that email in their inbox — not when they click reply, but when they first view it.

Read receipts are useful when you need to know whether an important message actually reached someone's attention. A manager sending a important date reminder, a contractor confirming a job start date, or someone asking for urgent feedback might all want this confirmation. The catch is that read receipts only work if the recipient's email program supports them and if they have not disabled them on their end.

Outlook lets you request read receipts in two ways: you can ask for them on individual messages, or you can set a default so Outlook requests them on every email you send. Most people use the per-message approach because requesting read receipts on every single email can annoy recipients.

Key Takeaways

  • Read receipts notify you when someone opens an email, but only if their email program supports them and they have not turned them off.
  • You can request a read receipt on a single message by clicking Options in the message compose window, then checking "Request a Read Receipt".
  • If you want read receipts on all outgoing mail, go to File > Options > Mail > Tracking and check "Always request a read receipt".
  • A recipient can refuse to send a read receipt, and many corporate email systems block them automatically for security reasons.
  • Read receipts work best between Outlook users; other email programs may not support them or may handle them differently.

How to request a read receipt on a single email

Open a new email in Outlook and write your message as usual. Before you send it, look for the Options tab in the ribbon at the top of the compose window. Click it.

In the Options tab, look for the Tracking section. You will see a checkbox labeled "Request a Read Receipt". Check that box. The moment the recipient opens your email, Outlook will send you a notification message in your inbox saying they have read it, along with the date and time.

After you check the box, send the email normally. The recipient will see a small notification asking whether they want to send you a read receipt — they can choose yes or no. If they choose no, or if their email system blocks read receipts, you will not receive one.

How to set read receipts as your default for all emails

If you send many emails that need tracking, you can tell Outlook to request read receipts on everything you send. Click File in the top left corner of Outlook.

Select Options from the menu. In the Outlook Options window, click Mail in the left sidebar. Scroll down until you find the Tracking section.

Check the box next to "Always request a read receipt". From now on, every email you send will include a read receipt request. You can still turn it off for individual messages by unchecking the box in the Options tab before you send, if you need to.

Why you might not receive a read receipt even if you request one

Read receipts depend on the recipient's email program and their settings. If someone uses Gmail, Apple Mail, or another email service that does not fully support read receipts, they may not be able to send you one even if they want to. Outlook users can usually send them, but not always.

Many corporate email systems automatically block read receipt requests for security and privacy reasons. The recipient's IT department may have disabled them across the entire organization. In those cases, you will never receive a notification, even though your message was delivered and read.

Some recipients also manually turn off read receipts in their own email settings because they do not want senders to know when they open messages. If someone has done this, Outlook will ask them whether to send a receipt, and they can choose not to.

The difference between read receipts and delivery receipts

Do not confuse a read receipt with a delivery receipt. A delivery receipt tells you that an email reached the recipient's mail server — it arrived. A read receipt tells you that the recipient actually opened and viewed the message. One confirms delivery; the other confirms that someone looked at it.

You can request both on the same message if you want. Delivery receipts are more reliable because they come from the mail server itself, not from the recipient's choice. Read receipts are more useful for knowing whether someone has actually seen your message, but they are less dependable.

What happens when you receive a read receipt

When a recipient opens an email you sent and read receipts are enabled, a notification message appears in your inbox. The subject line will say something like "Read: [Original Subject Line]". Open that message and you will see the date and time the recipient opened your original email.

Read receipts are just regular messages, so you can delete them, file them, or leave them in your inbox. They do not require any action on your part — they are purely informational. If you receive many read receipts, you might want to create a folder for them so they do not clutter your main inbox.

When to use read receipts and when to skip them

Use read receipts when you need confirmation that someone has seen an important message: a job offer, a important date, a critical update, or a request for urgent feedback. They are also useful when you are following up on something and want to know whether the person actually read your first message.

Skip read receipts for routine emails, casual messages, or anything you would not feel awkward asking about in person. Requesting read receipts on every single email can feel like you do not trust the recipient, and it may damage working relationships. Use them sparingly and only when you have a real reason to know whether someone opened your message.

Frequently Asked Questions

Can I tell if someone refused to send me a read receipt?

No. If someone declines to send a read receipt or their email system blocks it, you straightforward will not receive one. Outlook does not notify you that the request was refused — you just never get the notification. After a few days, you can assume they either declined or their system does not support it.

Do read receipts work if I send an email to Gmail or Yahoo?

Probably not. Gmail and Yahoo Mail have limited support for read receipts. Even if you request one, the recipient may not see the option to send it, or their email program may not be able to send it back to Outlook. Read receipts work most reliably between Outlook users.

If I turn on read receipts for all emails, can I turn it off for just one message?

Yes. Even if you have set read receipts as your default, you can uncheck "Request a Read Receipt" in the Options tab before you send any individual message. This lets you keep the default on but make exceptions when you need to.

Will the recipient know I requested a read receipt?

Yes. When they open your email, Outlook will show them a notification asking whether they want to send you a read receipt. They will see that you requested one, and they can choose whether to grant it.

What if I accidentally request a read receipt on a sensitive email?

You cannot unsend a read receipt request once the email is sent. If you realize you made a mistake, send a follow-up email without a read receipt request, or contact the recipient directly to explain. Most people do not mind read receipt requests, but if you are concerned, a quick message can clear it up.
