Well, here's a user story: You're Kanye West. Lots of other aspiring hip-hop artists want them to know about you because you're Kanye West. As a result, your regular inbox gets 250 emails a day from said hip-hop artists. So if you're Kanye West, you stop using email all together because you can't filter out the noise. You go to this email service, though, and you get 5 emails a day, and they're from Jay-Z, Rihanna, Def Jam Records, Barbara Boxer, and an up-and-coming regional hip-hop artist who sold 12,000 records, has a growing following, and just barely met the standard to gain access to the service. Those emails would be far more useful to Kanye, and he would check that inbox far more often because of it.
