Im curious to know what kind of job you have in which you don't get lots of emails? Maybe its because I've always had jobs working with customers but from my experience customers love sending emails.
Yeah, perhaps my comment on work email only applies to people in my line of work, engineering and not working directly with customers. For people on the customer side maybe it's unavoidable (although there are apps attempting to address this). But as far as non-customer-facing engineers go, I've found that if you're constantly flooded with email you're probably in an organization with lots of bureaucracy where few people feel empowered to make decisions. For instance, when I want to hire someone (I manage), I do it by sending an email to the HR person saying essentially 'hire them'. My boss has empowered me to make this decision and no other departments get in the way, except if they limit the budget.
