MailPoet on "[Plugin: MailPoet Newsletters] Send newsletter just to user didn't open de first newsletter"

I would like to send a standard newsletter but then, send another newsletter to the same list but only for those who have not opened the email or who opened but didn't click in link.
I have no problem to send the first email but the next I don't know how I do.

@ luizcarlosgimenes if you go into the MailPoet Stats page, you can view unopens and create new lists from these unopens. Unfortunately, this is only available in the Premium plugin.
