E-mail messages can be intercepted or read by an unauthorized individual.
When you want privacy, one way is to encrypt your documents before you attach them to your email message.
Microsoft Office, for Windows and Mac, has a feature on the File menu called Protect Document. Choose that option, and enter a secret password.
Use a phrase such as: the chairs are in a row.
E-mail that file to your recipient.
Then, phone, or text, the password to your recipient. If you email the recipient the password, even if it is in a separate email message, whoever is reading your email messages will receive both the attachment and the secret code.
Please forward this to any of your friends who may want to send sensitive email attachments.
