To check the email header in Gmail, you can follow these steps:

1. Log in to your Gmail account.
2. Open the email you want to check the header for.
3. Click on the three vertical dots at the top right corner of the email.
4. Select "Show original" from the dropdown menu.
5. A new window will open with the email's source code, including the header information.

Alternatively, you can also use the "View source" option to view the email's source code, including the header information. To do this:

1. Log in to your Gmail account.
2. Open the email you want to check the header for.
3. Click on the three vertical dots at the top right corner of the email.

The email header typically includes information such as:

• The sender's email address
• The recipient's email address
• The subject line
• The date and time the email was sent
• The IP address of the sending server
• The authentication information (e.g. SPF, DKIM, DMARC)

You can use this information to verify the authenticity of the email and detect potential spam or phishing attempts.

Note: The "Show original" and "View source" options may not be available for all emails, especially if they are large or contain sensitive information.
