IP Reputational risks in Survey Broadcast applications

I am currently working on a ‘Send Surveys’ application where a user can select multiple contacts from an address book and send an Email Broadcast with a link to the Surveys webpage.

I wonder if the recipients in Contact List are in hundreds (or even bigger) would it effect the IP reputation of sending email server? Is there a chance that receiving email engines i.e. Hotmail, gmail would start putting these emails into junk/spam box? Is there an IP Reputational risk involved here?
