Last year I wrote a column about some "not-so-obvious" things in the world of email that I'm thankful for. I focused on the people and technologies that keep email safe and secure. To be honest, I'm still thankful for all those things. While the fight against spam, phishing, spoofing and more wins many battles, the war continues and there is much work still to be done. This year, though, I wanted to turn my attention to more aspects of the email ecosystem that I think give us reason to be grateful.
