In many cases, as soon as I see the welcome email, I hit report spam to block any further email. If it's something I will be using for a long time or for specific purpose, I will bother fiddling with their email settings so I don't get overloaded. If it's a one-off or an app or something, I literally never want to hear from you. So I preemptively mark the first email as spam so I never have to see another one.
No, Runkeeper, I don't need an email when I set a personal record. You told me that in the app, literally as it happened. That's why I reported your email as spam and blocked everything you have to say to me. You're an app, you already have a way to contact me.
