Email campaign not delivering 100%

Hi, I have had a lot of friends say they didn't receive our newsletter (it's not in their junkmail) and was just wondering why it says 100% sent but only 97% delivered? Why are those 114 people not receiving the email campaign? 

I've tried to find the email addresses for those "sent" and "delivered" categories but I can't find a way to view them or export them. I would like to find a way to see those 114 that weren't delivered so I can try and resend to them.

I have one friend whose email address is in the system, she subscribed a day before the blast went out and under her profile it says she is subscribed to the newsletter mailing list but she still didn't receive the email.

This was the folder with csv files i got after the campaign went out and i don't really know what that means but her address is not in here anywhere:
Unsubscribed users: 1
Subscribed users: 44
Cleaned: 1

Hey - I have had the same issue, most of my emails are not being delivered which is incredibly detrimental and frustrating. 

If you get anywhere with this let me know..
