What a read receipt does in Gmail
A read receipt is a notification that tells you when someone has opened an email you sent them. In Gmail, when you turn on read receipts for an email, you get a small notification — usually a checkmark or a timestamp — showing that the recipient opened the message. This is different from a delivery confirmation, which only tells you the email reached their inbox.
Gmail's read receipt system works in both directions. You can request a read receipt when you send an email, and you can also choose whether to send read receipts back to people who request them. The person receiving your email will see a request asking if they want to let you know they've read it.
One important thing to understand: Gmail's read receipt is not foolproof. A recipient can decline to send you a read receipt, and some Gmail settings or third-party tools can block read receipts from being sent at all. So a missing read receipt does not necessarily mean someone ignored your email — it might just mean they declined to share that information.
Key Takeaways
- Gmail does not have a built-in read receipt feature in the standard web version, but you can use third-party extensions like Mailtrack or Boomerang to request and track read receipts.
- When you send an email with a read receipt request, the recipient sees a prompt asking if they want to notify you that they've read it.
- Recipients can choose not to send you a read receipt, so the absence of one does not mean they ignored your message.
- Gmail's mobile app does not support read receipts through extensions, so this feature only works reliably on the desktop web version.
- Some organizations block read receipt requests for privacy reasons, so your request may not reach the recipient at all.
How to set up read receipts using a Gmail extension
Gmail itself does not have a native read receipt button, so you will need to install a browser extension to use this feature. The two most common options are Mailtrack and Boomerang, both of which are free to start and work with Gmail in your web browser.
To install Mailtrack: Go to the Chrome Web Store, search for "Mailtrack," and click the blue "Add to Chrome" button. A popup will ask you to confirm — click "Add extension." Once installed, you will see a Mailtrack icon appear in your Gmail compose window. When you write an email, look for a small icon (usually a checkmark or envelope symbol) that lets you toggle read receipts on or off before you send.
To install Boomerang: Go to the Chrome Web Store, search for "Boomerang for Gmail," and click "Add to Chrome." Confirm the installation. In your Gmail compose window, you will see a Boomerang button. Click it, and you will see options including "Get read receipts." Toggle this on before sending your email.
Both extensions work the same way once installed: when you send an email with read receipts turned on, the recipient gets a notification asking if they want to let you know they have opened the message. If they agree, you will see a timestamp or notification in your Gmail inbox showing when they read it.
What happens when someone receives your read receipt request
When you send an email with a read receipt request, the recipient does not see anything unusual in their inbox. However, when they open the email, a small prompt appears — usually at the bottom of the message or in a banner — asking something like "Marcus Chen would like to know when you read this message. Let them know?"
The recipient has three choices: they can click "Yes" to send you a read receipt, click "No" to decline, or straightforward ignore the prompt. If they click "Yes," you will get a notification in your inbox showing the date and time they opened the email. If they click "No" or ignore it, you will not receive any notification.
Some email systems and organizations automatically block read receipt requests for privacy reasons. If the recipient's email system has this setting turned on, they may never even see the prompt, and you will not receive a read receipt even if they open the email.
How to see read receipts you have received
Once someone sends you a read receipt, you will see it in your Gmail inbox as a notification or label, depending on which extension you are using. With Mailtrack, you will see a small checkmark or timestamp appear next to the email in your inbox list, and you can click on the email to see more details about when it was read.
With Boomerang, read receipts appear in a similar way — you will see a notification in the email itself or in your inbox showing that the recipient has read your message. Both extensions also let you click on an email to see a timeline of when it was delivered and when it was opened.
If you do not see a read receipt for an email you sent with read receipts turned on, it means the recipient either declined to send one, their email system blocked the request, or they have not opened the email yet.
Why Gmail does not have built-in read receipts
Gmail's parent company, Google, has chosen not to build read receipts directly into Gmail the way some other email services do. This is partly a privacy choice — many people prefer not to share information about when they read emails, and Google respects that preference by not making it a default feature.
Another reason is that read receipts can create awkward situations. If someone knows you have read their email, they may expect an when ready response, which can add pressure to your inbox. By keeping read receipts optional and requiring a third-party tool, Gmail lets users decide whether they want this feature without forcing it on everyone.
Microsoft Outlook and some other email services do offer built-in read receipts, but they work similarly to Gmail extensions — the recipient can still decline to send one, and many organizations disable them for security or privacy reasons.
Limitations and privacy considerations
Read receipts are not a reliable way to confirm someone has actually read and understood your email. A read receipt only means the email was opened — it does not tell you whether the person read the whole message, understood it, or will act on it. Someone might open an email by accident and close it when ready, and you would still get a read receipt.
Privacy is another consideration. Some people find read receipts intrusive because they feel like being watched. If you regularly request read receipts, some recipients may start declining them or blocking them entirely. In professional settings, read receipts are generally acceptable, but in personal communication, they can feel pushy.
Corporate email systems often block read receipts at the server level, which means your request will not reach recipients at those organizations at all. If you are trying to track emails sent to a large company, read receipts may not work for most of those recipients.
Alternatives to read receipts
If you need to know whether someone has seen your message but do not want to use read receipts, there are other options. You can ask the person directly in your email: "Please let me know when you have seen this." You can also use Gmail's scheduling feature to send a follow-up email a few days later if you have not heard back, which serves as a gentle reminder without being intrusive.
For important messages, you can request a response in your email itself — for example, "Please reply to confirm you received this." This gives you a clear signal that someone has not only opened the email but also engaged with it enough to respond.
If you are managing a team or project, tools like Asana, Monday.com, or Slack often provide better visibility into whether people have seen messages and tasks, because they are designed specifically for that purpose rather than being add-ons to email.
Frequently Asked Questions
Can I use read receipts on Gmail's mobile app?
No. Browser extensions like Mailtrack and Boomerang only work on the desktop web version of Gmail. The Gmail mobile app does not support these extensions, so you cannot request or track read receipts from your phone or tablet. You would need to use the web version on a computer to access read receipt features.
Does the person know I requested a read receipt?
Yes. When someone opens your email, they see a prompt asking if they want to notify you that they have read it. They will know you requested a read receipt, though they can choose to decline without you knowing they declined.
What if someone turns off read receipts in their Gmail settings?
If a recipient has disabled read receipts in their email system or browser settings, they will not see your read receipt request at all, and you will not receive a notification when they open your email. Some organizations also block read receipts at the server level, which prevents the request from reaching employees entirely.
Can I turn off read receipts so people cannot track when I read their emails?
Yes. In most email systems, you can choose not to send read receipts when someone requests one. When you see the prompt asking if you want to notify them, you can click "No." However, there is no universal setting to block all read receipt requests — you have to decline them individually each time.
Is there a difference between read receipts and delivery confirmations?
Yes. A delivery confirmation tells you the email reached the recipient's mail server — it arrived in their inbox. A read receipt tells you they actually opened and viewed the email. Delivery confirmation happens automatically in most email systems, while read receipts require the recipient's permission.
