Organizing email between your computer and cell phone

My current email strategy is to use Google Apps for your Domain with my iPhone with the Apple Mail client. Because I am constantly referring to my ‘Sent Items’ and projects are sometimes managed through email, keeping my mail synchronized and organized is a challenge.

Here are some approaches:

1. Keep mail on the server for a week

Each time your laptop or phone client retrieves messages via POP (every 5 minutes, etc) you will get duplicate messages on your laptop and phone.

Mail Prefs

By setting your preferences like the above screenshot you will not surpass your quota on the mail server.

2. Whatever device you are using is the “master”

Setup both your laptop and your phone to “delete messages from the server after downloading”. Whichever mail client downloads the message first gets to keep it. This means when your computer if off your phone should be fetching your email, when you are using your computer to retrieve mail, turn off email on your phone. Some POP clients I have seen for the phone allow you to define time ranges for retrieving mail (ie: before 7am and after 7pm).
