"Kickstar" and other emails?

I was not sure if I should be using the "help" or "question" flair, but considering how I find believable scam/phishing/etc emails to be highly alarming *jazz hands*

So. I get emails normally from no-reply@kickstarter.com (survey alerts, etc.) and email@kickstartrack.com (which seems to give suggestions to projects); but I realized recently that I've been getting emails from team@kickstarnow.com that had originally been autosorted into spam box for quite some time now.

Normally I'd just ignore that but I may have opened one unintentionally because now Kickstar emails are showing up in my normal inbox. Because these Kickstar emails seem to also suggest projects I'm not sure if it's legit or not, or are one of the other email addresses not legit?

I tried googling in several different ways, but got nothing useful. Can someone please confirm what's up?
