Like for example, Paypal loves to tell me I removed a card from my account, but there's no way to turn that off in their dashboard. They just fire off every activity I've made with no option to stop these cruft emails from accumulating. Now multiply that same situation to 100x services I've created with my account and you have a big problem.
I recently heard Mozilla are offering a throwaway/disposable email service for $1.00/month and I'm excited for that and might try it, but I often want emails tied to my account and not some proxy service that could shut down at any moment and prevent me from doing password resets or reclaiming my account!
How are you people coping with an overflowing Inbox, what's your strategy?

edit: If there's some spam-ish stuff going on and I can't easily deactivate it, then I'll just spamblock them, because fuck them.
Second, Gmail and every other email provider, together with my beloved thunderbird have options to set rules to email that do different stuff on an email based on conditions like:
if subject contains "hi, hi", send to spam
if email is to gostsamo+paypal@example.com and body contains "card removed", send to trash
But, if me+paypal@domain.foo and me+irs@domain.foo are sending you different volumes of traffic, this could help you filter.
