Email account holders can stop junk mail from getting to their inbox by clicking the "unsubscribe" link in unwanted emails or by marking unwanted emails as Spam. Additionally, being selective about distributing an email address can reduce the number of emails received and the likelihood of spammers sending marketing materials and other unwanted communications via email.
Some experts recommend establishing a separate email address that is used for registering on websites and with groups online. Reserve a main email for business contacts only. Additionally, the email used should not identify the person using it by name but should be an alias of some sort to avoid becoming a target of spammers.
Some email clients are set up to prevent spam. Outlook is one such program that segregates mail that appears to be spam. Outlook also has a program that allows users to preview the email instead of opening it. This prevents the sender from thinking that the email was opened, which in turn triggers follow-up emails.
Using an email provider that blocks unwanted mail can help. For example, Yahoo blocks spam emails. If a lot of spam is coming through, changing the email address and starting over from scratch may be the best option.
