Building a list of subscribers can be as easy as purchasing a few thousand email addresses from list marketers, but that temptation should be avoided. Not only will your new subscribers not appreciate receiving unsolicited e-mails, many of them might wonder who the heck you are in the first place. That’s because a list broker isn’t likely to target your niche as closely they need to in order to get great results.
Opt-in subscribers who sign up of their own accord are by far the best subscribers you could hope to have for your newsletters. These folks have already expressed an interest in your work and will deliver those higher open rates you crave.
