3: Have Your Subscribers Spread the News
If they find your newsletter of value, ask your subscribers to forward it to a friend. Better yet, send them to a page listed or linked in your newsletter where they can enter the email addresses of friends, family, and colleagues whom they feel would find your newsletter of value. Of course, you need to confirm the referred address via email, politely saying that so-and-so thought they would be interested in a subscription, and then give them a chance to opt out before you include them in your house list. The last thing you want is to be accused of spamming.
