How can you identify a secure email?

A secure email can be identified primarily by the fact that it comes from a verified domain. This means that the sender's email address should match the official domain associated with the organization or individual. Email addresses can be easily spoofed, so confirming the domain helps ensure that the message is genuinely from the expected source and not from a malicious entity trying to impersonate someone else.

While other factors such as the presence of attachments, formatting, and content might give some clues about an email's security, they do not provide definitive proof. For instance, emails can contain attachments that are safe, and the format (plain text or images) does not inherently determine the security of the email. Therefore, checking the domain is one of the most effective ways to assess whether an email is secure or potentially a phishing attempt.
