How to know person has seen the mail in gmail

In Gmail, there isn't a built-in feature to confirm whether someone has seen a specific email or not. However, there are a few workarounds to help you determine if someone has viewed an email:

1. Read Receipt: You can request a read receipt from the recipient by adding a "Read Receipt" option to your email. This will send a notification to your email when the recipient opens the email. To do this:
   • Compose a new email or reply to an existing one.
   • Click on the three vertical dots at the bottom of the compose window.
   • Select "Show original" from the dropdown menu.
   • In the "Show original" window, click on the "Request read receipt" checkbox.
   • Send the email as usual.
   • When the recipient opens the email, you'll receive a notification in your Gmail inbox.
2. Delivery and Read Receipts: Some email clients, like Microsoft Outlook, offer delivery and read receipts. If the recipient uses one of these clients, you might receive a notification when they open the email. However, this feature is not universally supported across all email clients.
3. Email Tracking: Some email tracking tools, like HubSpot or Yesware, can track when an email is opened and provide you with analytics on how recipients interact with your emails. These tools often require you to install a browser extension or add a tracking link to your email.
4. Check the email's "Seen" status: In Gmail, you can check the "Seen" status of an email by hovering over the email in your inbox. If the email has been opened, you'll see a small clock icon next to the email's timestamp. However, this method is not foolproof, as the recipient might have opened the email and then closed it without marking it as "Read."
5. Ask the recipient: If you need to confirm whether someone has seen an email, you can simply ask them. This is the most straightforward and polite way to get an answer.

Keep in mind that there are limitations and potential issues with these methods. For example, some email clients might not support read receipts, and recipients might not open the email even if they've seen it. Always consider the recipient's privacy and consent before requesting read receipts or using email tracking tools.
