Spam email refers to unsolicited messages sent in bulk, often for advertising purposes. These emails can clutter inboxes and may contain misleading information or offers that are too good to be true. Many spam emails promote products, services, or scams, and they can sometimes include harmful links or attachments. Email providers use filters to help identify and block spam, but some may still slip through, making it important for users to be cautious and avoid engaging with suspicious messages.
