I unsubscribe anything that is not a person or relevant notification even if I pay for a service. [flight itinerary w/ confirmation number = ok, Spotify trending = not ok]. I suspect other people do as well.
In general you can turn off every notification option companies give you, without fear, because they are more or less required by law to send you the "transactional" (useful confirmations and notifications) emails.

I can understand there being a gray area around what is important information and what is marketing, but not getting password reset emails is just a bug. That never makes any sense and I highly doubt it was intentional.
I have to say, I'm getting quite annoyed with what some companies consider "essential" emails.
Take eBay, for instance. For certain orders (and not others), I have begun to receive emails for each of the following:
• Order confirmation
• Preparing for shipment
• Shipped
• Will be delivered today
• Actually delivered.
This is useless noise. Fine to provide the option, but damn it, I've already opted out from as many messages as possible. The only email that should be "required" is order confirmation, and maybe one additional email for when the item has shipped.
