This is the case even for free subscriptions. A couple years ago I went through my emails and every time I came across something from a list I hadn't bothered to read in some time, I unsubscribed, then searched/deleted what was cluttering my mailbox.<p>It actually took me a <i>week</i> to complete. Now I have it to the very few subscriptions I like enough to read often, and aren't just sending me what I have already read online days prior.<p>Subscriptions force you to act in some manner - even if it is just to click and delete.<p>We used to say "That could have been an email" but we've reached "That could have been a social media post that I can scroll past if I don't want to read it."
