When you send a message with styling, links, or files attached, you're creating opportunities for things to go wrong—from accidentally exposing sensitive information to opening doors for malware. Understanding how email actually handles these elements helps you spot what's risky and what's safe, whether you're sending a resume, sharing photos, or forwarding documents at work.
These articles explain how to format emails without creating security gaps, what makes certain attachment types dangerous, and how to share files in ways that protect both you and the person receiving them. You'll learn why some formatting choices matter more than others, how to spot suspicious attachments before opening them, and practical ways to handle common situations like sending passwords or large files.
