Emails moved to trash are permanently deleted by Google after 30 days, at which point the storage space is fully released. To reclaim space immediately, go to Gmail Trash folder and click Empty Trash now.

Do unused credits roll over to the next month?

Cleanup credits do not roll over between billing periods. They reset at the start of each new cycle. If you consistently need more credits, upgrading to a higher tier provides significantly more capacity at a better per-email rate.
