Some of this could be solved if we could create "expiry filters" to delete after __ days.
There's so much "junk" in my inbox that was actually important in the moment, but by the time it's assuredly useless, a new wave of mail would have pushed it out of sight and mind.
Service notifications (outage report, terms of service updates, watched Github repos, 2-factor email auth codes, someone "followed" you), delete after a week.
Newsletters - delete after a month.
Also merging might be useful -
Receipts - merge by month after 6 months (email templates for each retailer are pretty similar, group the items?), maybe export to google drive / dropbox and clean itself up from my mailbox.
