I didn't.

Or rather I took back control. I have now 2 email addresses - one for humans, one for the rest.

And I systematically unsubscribe from every email I don't want to receive (gosh I miss Europe for that), I delete everything that I have no reason to keep, and I archive anything that needs to be kept.

It demands a lot of effort at the beginning. But now my inbox is useful again.

Is there an automated way of unsubscribing?

Unroll.me is owned by Rakuten, and they clearly state that they extract stats and trends from your transactional and commercial emails.

Set up an email for each subscription. E.g. [e-mail]. Block anything coming without a + extension. When you want to unsubscribe, create a rule to delete any email from the specific address you set up for that subscription.

Not really - some webmail clients act like they have one but they almost never works.

The other way is when you create an account somewhere, first thing you have to do is to go in their privacy and / or notifications settings. Stop it at the source.
