I have deleted most of my gmails, now I only have one because is the main email where I have a lot of accounts signed up that I don't remember, when I get an email from those services I change my email immediately. Now I use http://posteo.de http://posteo.de as my main email, any new contact or new service I use this email. The only con is that I can't use my own domain on this, but I don't really care. The only thing that keeps me from closing all my google accouns is google maps, for a person that sucks memorizing street names and locations this is very useful for me.
