Within the campaign dashboard for individual sends, you are able to view the recipient activity. To dig deeper into your analytics, you can now export a list of all email addresses that have not opened your communication.
To do so, go to your specific campaign and click the "Download Report" dropdown. From there, select "Download Unopened". You will then receive an email with a CSV list of all emails with "0" opens.
