I moved over my domain email to Gmail five years ago and have never looked back. My current stats are Inbox (39,745) and Spam (2,399) where I receive on average about 325 emails/day with 25 of these being automatically filtered as important and the remaining 300 designated as spam which are automatically deleted after 30 days. In the past I managed my own email server which I accessed through my Outlook client which took about an hour out of my day to manage and wade through all the emails especially since I had to keep refining my junk email rules to keep out all of the spam which for the most part is automatically done by Google when using Gmail. In the five years since, I manage everything remotely through my Google Dashboard with nothing downloaded locally and with Google's powerful search capabilities I am able to quickly find any email I have ever sent or received without having to necessarily set-up the folder infrastructure to keep everything neat and tidy like I use to have to do with Outlook and instead just use various labels and such and sometimes not even these as their search works so great. I literally have gained back an hour to my schedule for everyday of the week which is some 365 hours/year or 9.13 forty hour weeks/year or one full 52 week year every 5.70 years if my quick off the head arithmetic is correct and I still never have ever deleted an email except for spam of course, but the pain of managing it all rest Google's more than capable hands and all for free at that leaving me to do other more productive and less mundane pursuits.
