Only 1 page fetched?

Hi I have like 25000 emails, read and unread. I am wondering when executing the script, the result I get is:

Email is worth the time, leaving as unread
Total number of unread emails fetched: 37
Total number of pages fetched: 1
Total number of emails marked as read: 0
Final number of unread emails: 37

How do I make it so the script goes through all 25.000 emails and deletes the ones that are not important?

@isafulf Any ideas?
