I use a spark as my OS X email client but my mail is hosted by Google. After about seven years I found that I reached Google’s free 15 GB email limit and I could not receive any more emails. I could have started all over again with a new Gmail account but I wanted to keep my existing Gmail address. I could have deleted some old emails but I wanted to keep a record of them all. What I did is I created a new gmail account to keep a record of my old emails before I deleted them. I copied all my emails to this account. Then I could delete all my emails and get some more room on my everyday Gmail account. Here’s how to do that.
