Here's one for all you gmail users. You have the option to be notified of only the first e-mail in a thread, or with each sequential message of the thread, depending on how often you like to be bugged I like to be notified of each email in the thread because generally they are important, and I don't like to miss out on important stuff. With the recent updates to the GMail application Google has burried the settings a bit further in the menu, but let's take a quick look at how to change the setting for yourself.

  1. Launch the GMail App
  2. Press menu, then more, then settings
  3. Click on the account you wish to manage
  4. Scroll to the bottom and select labels to notify
  5. Click on inbox then the bottom option "notify once" is what you will want to toggle

Having the box checked will notify you only of the first message, and unchecking the box will ensure that you are notified of each message that arrives.
