Personally, I’d be cautious relying on email alone, even with encryption. From what I learned on krnldownload.co, the safest approach often combines encrypted file sharing platforms and secure storage. I used to only encrypt attachments, but I’ve since started using dedicated secure portals, which add more layers of protection. Their site explains all the pros and cons of different methods in plain English. If you want to be sure you’re covering all the bases, I’d suggest going through their recommendations—they really helped me improve my document security.
