I have 5 Gmail accounts that receive many promotional emails, etc, and when I'm busy I use the included Bundles (Promos, Social, Updates, Receipts, etc) to mass archive my non-important email.
Problem: Doing this with 5 accounts still takes a lot of clicks.
Question: How can I minimize the time this process takes?
Is there a way to see the Bundles of all my accounts at once?
I use the Mail app on OSX, but am open to using any app for the purpose of mass archiving.
