For many companies and individuals, spam is an annoyance and undesired expense. Many products and services are available to help avoid spam. Only by using these tools can we help to stem the tide of the ever-increasing unsolicited e-mails that reach our inboxes every day. If companies with which you do business send you spam, make them stop. Support programs such as the Trusted Sender Program and efforts from companies such as the SpamCon Foundation to assist antispammers.
If you are a solution provider or developer, create e-mail-friendly solutions. Make sure you give customers an easy way to manage e-mails from you. Register with companies that may mistakenly tag your e-mails as spam.
