Still sending naked email?

“In a world of repressive governments and a growing reliance on insecure networks, there’s no way anyone can be sure their most sensitive messages aren’t intercepted by the forces of darkness. But you can make it mathematically improbable that all but the most well-funded snoops could ever make heads or tales of your communications.” Use Dan Goodin’s step-by-step guide to email encryption and keep your communications private.

Stop spam

“Once your email address is in the hands of spammers, regaining control of your inbox is a very, very difficult job indeed.”

Forwarded Messages

If you send an email to multiple recipients, send it using the Bcc: field. Never put multiple recipients into the To: or the Cc: fields, because a message forwarded in this way will soon accummulate hundreds of email addresses as part of its header. In the wrong hands, such a message can be extremely damaging to its previous recipients.

Electronic Greeting Cards

Do not use electronic greeting cards. While these are fun and easy to send, they place your email address and that of your friend into a database. Unfortunately, many greeting card sites are mere collection points for email addresses and make money by selling on their database to spammers.
