Avoid opening email attachments from unknown senders. Delete such email messages immediately and mark them as spam.
If the content of an email from a known sender seems strange or inappropriate, delete the email and contact the sender using a different method.
Avoid putting confidential information in your email.
Avoid writing your email address on websites that advertise promotions or contests. These sites may simply be a way to obtain valid email addresses in order to send mass emails or spam.
Do not respond to spam—not even to ask for your address to be removed from a list. The unsubscribe link could be used to validate your address and you may receive even more spam as a result. Instead, delete the message and mark it as spam.
