A couple of nuggets of knowledge about SPAM from the Director of Internet Marketing (aka, the Queen of Email; aka, the Fighter of SPAM).
1. When you view an email in your preview window of Outlook, Apple Mail, or another mail reader, you’re opening the email–at least in the mind of the spammer who sent you that email. That’s right, when spammers send you an email, and you view it in your preview window, they do cartwheels because they know you’re a real person with a real email address who they can keep spamming to improve their open rates. Good for spammers, bad for you. Word to the wise: Be careful using the preview screen to read email, or you’ll become an even bigger target for spammers.
2. The auto-response message that tells everyone who sends you an email that you’re out of the office on vacation in Aruba goes out to EVERYONE, including spammers. Replying to spammers is, in short, a bad idea. So… if you get a lot of SPAM in your inbox, think twice about the auto-response.
