What you should do is download a free email client, like Thunderbird, and then use encryption on your email. It’s still not foolproof, but it makes it considerably harder to crack your correspondence.

That's wonderful.
But I'm with Grandma. How do we deal with learning a new email client?
And how do we get around the sites tha show us a "email us" button, but will only continue if we use MS Outlook as our mail client?

Thunderbird is real easy to use, and there is PLENTY of on-line help for it.

If you allow it to be your email client, it will give you an email window when you click on an email link in your browser.

You can send documents even more securely by using ziptr.

However, you and all your correspondents must have ziptr accounts, which are free.
