But I like sending links to important articles or videos. How can I help my friends and relatives feel safe and yet open the email.
Easy, I send each of my friends and family an email that says:
“Please check this email by writing back and asking if I really sent it, or even better by calling me at 339-201-6010 From now on, when I send you email with a link, I will put the word fadoodle* at the bottom, so that you know it is really from me. Please do the same if you are sending me a link”
*Fadoodle is any made up word and not the one I use
This simple mechanism reassures the recipient that the email really came from you. You can use any word, but you are best doing what you would do with a password: the longer the better.
There definitely are more secure ways to do this, but this is sufficiently secure for me, and it is painless.
