When Do You Check Email?

My phone checks my email accounts every 15 minutes. When I get a new email message, the phone will make a notification tone which I will then check to see if the email is legitimate, or junk. If it is junk email, I will delete it right away from the phone. If it is a legitimate email, I will usually go to my computer, and open the mail app on my PC. I will then compose the email, and send it off.
