How Can I Reduce the Amount of Spam that I Receive?
Try not to display your email address in public.
That includes newsgroup postings, chat rooms, websites or in an online service’s membership directory. You may want to opt out of member directories for your online services; spammers may use them to harvest addresses.
Read and understand the entire form before you transmit personal information through a website.
Some websites allow you to opt out of receiving email from their “partners” — but you may have to uncheck a preselected box if you want to opt out.
Decide if you want to use two email addresses — one for personal messages and one for newsgroups and chat rooms. You also might consider using a disposable email address service that creates a separate email address that forwards to your permanent account. If one of the disposable addresses begins to receive spam, you can shut it off without affecting your permanent address.
Use a unique email address. Your choice of email addresses may affect the amount of spam you receive. Spammers use “dictionary attacks” to sort through possible name combinations at large ISPs or email services, hoping to find a valid address. Thus, a common name such as jdoe may get more spam than a more unique name like jd51x02oe. Of course, there is a downside — it’s harder to remember an unusual email address.
Use an email filter. Check your email account to see if it provides a tool to filter out potential spam or a way to channel spam into a bulk email folder. You might want to consider these options when you’re choosing which Internet Service Provider (ISP) to use.
Reduce your exposure to "harvesting".
Once your email address is on a spammer's list, it can be very hard to get off, especially if he's selling it. Here are some tips on how to stop spam before it starts.
Who's Spamming Who? Could it be You?
Spammers may be using your computer to send unsolicited — and possibly offensive — email offers for products and services. Spammers are using home computers to send bulk emails by the millions. Indeed, computer security experts estimate that as much as 30 percent of all spam is relayed by compromised computers located in home offices and living rooms, but controlled from afar.
