Chester,
If you can cope with notifying everyone from whom you want to receive emails of a change in your address, then there are three things you should do to ensure that you stop receiving spam.
1.
Change your email address so that it has numbers in it (e.g.
Chester867Taje@somethingorother.com). Spammers generate email addresses by using first and last names from sources such as telephone directories. Introducing numbers into your email address makes it impossible for a spammer to generate it.
Protect this email address. Give it only to your bank, your family, your close friends --- people and organizations from whom it is important that you receive email and whom you trust to protect your address.
2.
Create an second, alternative, email address under Yahoo, or Google, or Hotmail and use it ONLY for registering on websites such as this one. Both Yahoo and Google have good spam filters which you can customize.
3. Never provide either of your email addresses to people who want you to register for a "free gift", or a "draw for a valuable prize". The whole point of these schemes is to collect email addresses which can be
sold to other organizations, some of whom send spam.
Best of luck,
