Never give your email address to anyone. Ever.If the only way someone knows your email address is for you to give it them, then that's just like having an unlisted phone number. You still may get some calls, but you'll get a lot fewer than if you're listed in the phonebook. I got rid of my drew@hevle.com email address about four months ago, because I was getting too much spam, and I created a new one. I have my own domain, so I can create as many new email addresses as I want. I was very careful not to give out the new address to any of my online bills, site registrations, purchases, etc., except for my bible class at Second Baptist. I wrote it down in a moment of weakness, thinking that it couldn't cause any harm. Well, they use
eVite quite a bit, and already I'm getting dozens of spam emails a day on my new address. One slip and you're done.

If you have to register for a site, use a fake email address, if you can. I just add the words NOSPAM to my real address (like drew@hevleNOSPAM.com), and that way, if a human being has to contact me, they can, but the automated systems won't be able to figure it out. If the site requires you to confirm your email address, for example by receiving a password or a key, you can use a throw-away account established just for that (see
Part 5 of this article). You can also use a service such as
BugMeNot that posts usernames and passwords in order to bypass compulsory site registration.
Never give out your e-mail address indiscriminately. If telemarketers can't get your phone number, they can't call. It's the same principal with unwanted email. The last time I went to [large computer retail store] the cashier asked me for my email address when I was checking out. I told her I didn't have one. They look at you funny, but some people still don't have email addresses, and why does [large computer retail store] need my email address? There's a blank for your email address on almost every form you fill out nowdays, but it's not required or even necessary for everything but purely Internet transactions. Just say "no", or "I don't have one", or "I can't give that out, it's my employer's policy". It should be your policy too.
Once your email address is on a spammer's list, it will be there forever. Spammers sell to other spammers, and they can get more money if they confirm that the address is live, or even more if they have someone who bought something (see
Part 10 of this article). Spammers don't even bother to check for duplicate entries, much less care if one of their thousands of emails didn't go through because it is invalid. I recreated the old drew@hevle.com account and checked the email for a few days, and it's getting more spam now (60+/day) than it was four months ago when I turned it off. Every spam email that goes to that address generates a bounce-back error message, but the spammers don't care, most of them don't even receive the errors because of forged headers (see
Part 3 of this article).
Never post your email address on the Internet. Spammers search web pages for email addresses (this is referred to as scraping) so if you sign someone's guest book or comment on their blog with your real email address, it won't be long before a spammer has it too. There are websites whose whole source of revenue is getting visitors to divulge their email addresses and then selling those names to spammers. Viruses are now being written to distribute malicious programs (e.g. a virus or a trojan) that scan the victim's hard drive looking for email addresses. So even if you only tell your closest friends your email address, a less discriminating friend could give your email address to spammers just by opening a suspicious email attachment and having your email address in their address book. Those big long headers on forwarded chain letters and jokes are great fodder for spammers, too. Product registration cards collect email addresses for revenue, and so do registrations with web servers. Online purchases do too. Responding only makes it worse (see
Part 3 of this article), any email messages you have exchanged with a spammer will just guarantee that you go on more lists. Other forms you fill in that request your email address may add you to spammers lists.
Even if you never tell anyone your email address, spammers can still get you by attempt to guess your email address given a traditional mailing list containing only names, street addresses, telephone number and employer details. Some spammers use these services so they can spam people who have intentionally withheld their email address (like you should). This is especially true if you use one of the bigger ISP's (see
Part 4 of this article), they'll guess johnAsmith@aolNOSPAM.com, johnBsmith@aolNOSPAM.com, johnCsmith@aolNOSPAM.com, etc. It's harder if you have a domain like hevleNOSPAM.com. They can still guess webmaster@hevleNOSPAM.com, accounting@hevleNOSPAM.com, sales@hevleNOSPAM.com. I get those all the time.
