We would like to send an e-mail out to user's who haven't renewed yet. The user's who have renewed have their current subscription expiring and then a future subscription that starts the day the current subscription ends. I can't figure out a way to filter to only get users who have not yet renewed their membership.
'Protect Content' > 'Email Users' > 'New Expiration Email' and select 'Send E-Mail Message' then set when to send E-Mail Message, for example on expiry day or so many days after.
