According to this email, the “server administrator” has sent you a confidential image. Supposedly, you can click a button in the email to view the image.
The email includes the logo for the popular web hosting system cPanel.
However, the email is not from any legitimate server administrator and has no connection to cPanel. Instead, the message is a phishing scam designed to steal your email account login credentials.
If you click the link in the hope of viewing the “confidential image”, you will be taken to a fraudulent website that asks you to enter your email address and account password into a login box.
Criminals can collect the information you enter and use it to hijack your email account. Once they have gained access to your account, they can use it to launch spam and scam campaigns in your name. If your account is linked to other services such as app stores and online file storage, the crooks can take control of those as well.
Email phishing scams like this are very common and take many forms.
