Tip #7 — Don’t Spam People!
It can seem awfully enticing that all you need to to make money is send an e-mail. This leads certain people to the dark side. Of course I'm talking about spamming. Even if their intentions started off good, spamming is highly tempting, and the laws can be confusing.
Spam is when you send unsolicited e-mails to people. It is actually against the law.
Three things you MUST do to avoid spamming people
The spam law states that you must make sure that you make it easy for people to unsubscribe from your list (a link at the bottom of the message is best) and that they have subscribed in the first place. You are also required by law to include your postal address with all messages that you send.

Building a relationship may take longer than spamming, but the profits will be far greater in the long run.
