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, you request a read receipt before you send the message — you cannot add one after. When the recipient opens your email, Gmail sends you a notification saying they have read it.
Gmail's read receipt system is different from some other email services. The recipient sees a message asking permission to send you a read receipt, and they can choose to allow it or decline. If they decline, you will not get a notification, even though they opened the email. This means read receipts in Gmail are not a may provide that you will know when someone reads your message.
Read receipts are useful when you need to confirm that an important message reached someone and that they actually opened it — for example, when sending a contract, a important date reminder, or instructions that require acknowledgment.
Key Takeaways
- You request a read receipt before sending an email by clicking the three-dot menu and selecting "Request read receipt".
- The recipient will see a prompt asking whether to send you a read receipt, and they can choose to decline.
- If the recipient declines or uses certain email clients, you will not receive a notification even if they open the email.
- Read receipts work best when both people are using Gmail or Gmail-compatible email clients.
How to turn on read receipts before sending
Open Gmail and start composing a new email. Click the three-dot menu icon in the bottom right corner of the compose window — it is next to the trash icon. A dropdown menu will appear with several options.
Look for the option that says "Request read receipt" and click it. A checkmark will appear next to it, showing that the read receipt request is now active for this email. You can now type your message and send it normally. The read receipt request will be included with the email when it goes out.
If you change your mind before sending, click the three-dot menu again and click "Request read receipt" a second time to turn it off. The checkmark will disappear.
What happens when the recipient receives your email
When someone opens an email you sent with a read receipt request, they will see a message at the top of the email that says something like "The sender has requested a read receipt for this message." Below that message, they will see two buttons: one to send the receipt and one to decline.
The recipient can choose either option. If they click to send the receipt, you will get a notification in Gmail telling you they have read the email. If they click to decline, you will not receive any notification. Some email clients and settings also send a decline notification automatically without asking the user, so you may see a message saying the recipient declined to send a receipt.
If the recipient uses an email service that does not support Gmail's read receipt system, they may not see the prompt at all, and you will not receive a notification.
When read receipts do not work
Read receipts in Gmail have several limitations. If someone uses Outlook, Yahoo Mail, or another email service that does not recognize Gmail's read receipt format, they may not see the prompt, and you will not get a notification. Even if they open your email, Gmail has no way to know.
Some recipients disable read receipts in their email settings, which means they will always decline automatically. Others may have their email client set to not load images or preview content, which can prevent the read receipt from triggering even if they do read the message later.
Mobile email apps sometimes handle read receipts differently than the web version of Gmail. A recipient using Gmail on their phone may not see the read receipt prompt, or it may not send properly depending on their app settings.
Read receipts versus delivery confirmation
A delivery confirmation is different from a read receipt. Delivery confirmation tells you that your email reached the recipient's inbox — it does not tell you whether they opened it. Gmail provides delivery confirmation automatically for most emails; you do not need to request it.
If you send an email and it bounces back because the address is invalid or the inbox is full, Gmail will notify you of that failure. That is delivery confirmation at work. A read receipt goes one step further and tells you the person actually opened the message and read it (or at least opened it).
For most everyday emails, delivery confirmation is enough. You know the email arrived. Read receipts are useful only when you specifically need to know that someone opened and saw your message.
Alternatives to read receipts
If read receipts are not working for you — perhaps because your recipients use different email services — you have other options. You can ask the recipient directly to reply to your email confirming they received and read it. This is more reliable than read receipts because it does not depend on email client compatibility.
For important documents or contracts, you can use a service like DocuSign or Adobe Sign that tracks when someone opens a document and even when they sign it. These services are more robust than email read receipts and work across different email systems.
You can also include a straightforward request in your email message itself: "Please reply to confirm you have received this." This works with any email service and any recipient, and it gives you a clear record of acknowledgment.
Frequently Asked Questions
Can I request a read receipt on an email I already sent?
No. You can only request a read receipt before you send an email. Once the email is in the recipient's inbox, you cannot add a read receipt request to it. You would need to send a new email with the read receipt option turned on.
Will the recipient know I requested a read receipt?
Yes. When they open the email, they will see a message at the top saying the sender (you) has requested a read receipt. They will know you want to know when they read it, and they can choose whether to send that information back to you.
What if someone declines to send a read receipt?
You will receive a notification that they declined, or you will straightforward not receive any notification at all, depending on their email settings. Either way, you will know the read receipt was not sent. You will not know whether they actually opened the email.
Do read receipts work on Gmail mobile app?
You can request read receipts through the Gmail mobile app the same way you do on the web version. However, recipients using the mobile app may not see the read receipt prompt, or it may not work reliably depending on their phone's email settings and app version.
Can I see a history of read receipts I have received?
Gmail does not keep a separate folder or list of read receipts. When someone sends you a read receipt, it arrives as a notification in your inbox like any other email. You can search for these notifications, but Gmail does not organize them separately or provide a report of which emails were read.
