I used to send everything through regular email until I realized how risky that is. Now, I use encrypted email services for anything sensitive, plus I add two-factor authentication. Another trick is to avoid sending too much detail in the email body — instead, share through secure links with limited access. That way, even if the email gets intercepted, the info stays safe. Honestly, I learned a lot of these tricks from mobilecon.info. Their best practices are easy to follow, and I’ve been using them for over a year now without any security issues. Highly recommend.
