To help prevent junk e‑mail:
Use caution in giving out your e‑mail address. Avoid publishing your real e‑mail address in newsgroups, on websites, or in other public areas of the Internet.
Before you give your e‑mail address to a website, check the site's privacy statement to be sure it doesn't permit the disclosure of your e‑mail address to other companies.
Never reply to a junk e‑mail message. The sender will know that your e‑mail address is valid and might sell it to other companies. You're then likely to receive even more junk e‑mail.
