How to check whether a mail is read or not

Checking whether a mail is read or not depends on the email client or service you're using. Here are some common methods:

Gmail

1. Log in to your Gmail account and go to the "All Mail" or "Inbox" tab.
2. Click on the three vertical dots next to the email you want to check.
3. Select "Mark as read" or "Mark as unread" to toggle the read status.

Outlook

1. Log in to your Outlook account and go to the "Inbox" tab.
2. Right-click on the email you want to check.
3. Select "Mark as read" or "Mark as unread" to toggle the read status.

Yahoo Mail

1. Log in to your Yahoo Mail account and go to the "Inbox" tab.
2. Click on the email you want to check.
3. Look for the "Mark as read" or "Mark as unread" button at the top of the email.

Other email clients

For other email clients like Apple Mail, Mozilla Thunderbird, or Microsoft Outlook, the process is similar:

1. Open the email client and go to the "Inbox" tab.
2. Select the email you want to check.
3. Look for a "Mark as read" or "Mark as unread" button or menu option.

APIs and programming

If you're using an email client or service programmatically, you can use APIs to check the read status of an email. For example:

• Gmail API: Use the users.messages.get method to retrieve the email and check the labelIds field for the "INBOX" label. If the email is read, the read field will be set to true.
• Outlook REST API: Use the GetMessage method to retrieve the email and check the IsRead property.

Keep in mind that some email clients or services may not provide a direct way to check the read status of an email. In such cases, you may need to use workarounds or third-party libraries to achieve this functionality.
