I do keep two separate e-mail accounts. One primary for work, and one primary for personal. I then set all of the various ones to automatically forward to one or the other based upon category. This makes it really nice so that I can 100% focus on work, and 100% unplug when I need to. I have my iPhone set to connect to both Gmail (personal) and my work one, so I still get immediate updates for both and can choose which one to pay attention to.

I honestly haven’t looked into Yahoo mail in a number of years. I used to run my own e-mail server for personal mail for both the experience and the security, but I signed up for a Gmail account when I took a trip out of the country a few years back. Well I fell in love with Gmail back then because of it’s simplicity as well as it’s then unheard of 1 GB worth of storage space, so I migrated everything from my personal server into it and shut down the server.

Not knowing much about Yahoo mail, here are some of the must-haves that make Gmail great for me.
- Not really “mail,” but it’s integration with Google Calendar. This provides business class calendaring for my personal use. The fact that I can then share it with both work colleagues as well as friends and family is a huge plus. I can also have a large number of sub-calendars. (I have one for work, one for social, and one for consulting jobs.)
- Exchange Sync – This allows my iPhone (and other smart phones) to connect to it just like a Microsoft Exchange server. So you get all of the neat stuff like server push, and instant updates to calendars.
- Lots of storage space. 7.7 GB last time I looked.
- The ability to send mail as a different address. This is nice because I can receive and send e-mail as my personal domain account, vs something @gmail. This helps with the validity of my professionalism for consulting purposes. (No one wants to hire “computerdude173@aol.com”)
