I was looking for inspiration for my mailing list strategy and chose to check out what the commercially cool kids were doing on Billboard’s Hot 100. I randomly chose 10 artists from this weeks Hot 100 and wanted to ask some questions: How hard is it to sign up to their mailing list? Do they have a mailing list offer with any free music? What are they offering to make me want to sign up? What catch phrases are they using to invite you to sign up?
