Gmail Has a Page You've Probably Never Opened
You're not drowning in promotional email because you signed up for too much. You're drowning because unsubscribing one message at a time is tedious enough that nobody does it. Gmail's "Manage subscriptions" view collapses that into one screen: every sender you're subscribed to, sorted by whoever floods you most, with a count of recent emails and a one-click unsubscribe.
Click it and Gmail sends the unsubscribe request for you. After that, mail from that sender goes to spam.
Finding It
Open mail.google.com, then Menu → More → Manage subscriptions. The worst offenders sort to the top, so the first few clicks do most of the work.
Then Clear the Backlog
Unsubscribing stops what's coming; it does nothing about the thousands already sitting there. That's a search-operator job — filter with something like category:promotions older_than:1y or is:unread older_than:6m, use "Select all conversations," and delete the lot in one pass. Block the repeat offenders so they don't come back.
What's in the Guide
The direct link to the subscriptions page, the four steps to reach it through the menu, the exact search operators to paste for a bulk cleanup, and the select-all-then-delete move that clears the backlog at once. No paid inbox app required.
