How to remail people who didn't open email

Britt Malka

I've checked this forum, but never found an answer that could help me with this problem:

How do I send an email to those who didn't open a particular campaign?
Hi there, I am probably missing something, But I cannot find a way to do it on the Setup or Details section. Thank you!
I feel a bit stupid :) where can I find the more options on this page, I seem to be missing something. Thank you!
