Unroll.Me will only move emails from your inbox to one of two places within your account.
When you elect to unsubscribe from a sender, Unroll.Me follows that sender's unsubscribe instructions. If, for whatever reason, that sender's unsubscribe instructions fail and that sender continues to send emails to your inbox, Unroll.Me will move those future emails from your inbox to your trash folder.
If you see emails you'd like to keep moving to your trash folder, then you should review and revise your "Unsubscribe" list here.
Additionally, if you add a sender to your Rollup list within your Unroll.Me settings, then emails that arrive in your inbox from those "Rollup" senders will be filtered out of your inbox and moved to the "Unroll.Me" folder in your email account.
If you see emails you'd like to keep moving out of your inbox and into your Unroll.Me folder, then you should review and revise your "Rollup" list here.
