How to check whether a mail checked by reciever

Unfortunately, there is no straightforward way to check whether a mail has been checked by the receiver, as it depends on the email client or service being used. However, here are some indirect methods to help you determine if a mail has been checked by the receiver:

  1. Read Receipt: Some email clients, like Microsoft Outlook, allow you to request a read receipt from the recipient. This will send a notification to you when the recipient opens the email. To request a read receipt, you can add the following code to the email body: Disposition-Notification-To: [email protected]
  2. Delivery Reports: Many email services, like Gmail, Yahoo, and Outlook, provide delivery reports that indicate when an email is delivered to the recipient's inbox. These reports may not necessarily indicate whether the email has been read, but they can give you an idea of when it was delivered.
  3. Email Client Settings: Some email clients, like Microsoft Outlook, allow you to set up notifications when an email is opened or read. You can check your email client's settings to see if this feature is available.
  4. Tracking: Some email services, like Gmail, offer tracking features that allow you to see when an email is opened or clicked. These features are usually available for paid accounts or for specific types of emails (e.g., promotional emails).
  5. Check the Email Client's Log: If you have access to the recipient's email client, you can check their log files to see if the email has been opened or read. For example, in Microsoft Outlook, you can check the "Sent Items" folder and look for the email's "Received" timestamp to see when it was opened.
  6. Ask the Recipient: If you have a direct line of communication with the recipient, you can simply ask them if they have checked the email.

Keep in mind that these methods may not always work, as the recipient may not have enabled read receipts, delivery reports, or tracking, or they may not have checked the email at all.
