BIG Mistake #5. They buy e-mail blasts
There are many companies that sell artists e-mail blasts to hundreds of thousands of people. What they don’t know is, it all goes to spam. The chances of someone important seeing that is almost close to none. Do not waste any money on e-mail blasts. Many of these companies promote a large number of releases and artists every day, making your chances even slimmer. When executives see any of this, they immediately flag it down as spam.
