I still have work to do in some of my individual file folders and I will be decluttering them (deleting old and obsolete emails) but for the time being, my inbox is functioning the way an inbox should function and I feel like a weight has been lifted. The maintenance process is working well and that feels wonderful!
The more I use the app, the easier it gets.. I have updated my email subscriptions several times since I installed the app and have added more to the rolled up emails as well as the unsubscribe category. I no longer dread opening up my email inbox.
