Leaving a great a company

Personally, I think the cult of 'exit emails' is vastly overrated unless you held a very senior position in the company and you held it for some time.

Otherwise it's just an exercise in narcissism to think that everybody in the company other than those that you yourself can think of are interested in your 'exit'.

Your close coworkers and your immediate contacts sure (if you're in sales or have other outside contacts that includes your customers to pass them off to your replacement), but everybody ?

"Send it to ALL" -- when I was working for banks with (tens of) thousands of employees, I often received such carefully crafted exit emails from people/departments I had never heard of. And I considered all of them SPAM.
