I'm not sure but IMO, its probably the bandwidth allocation of the NBN and your Mobile Data Blocks. 

If you notice, when using smart phone some of application have a feature that controls the Data Usage. Maybe your Email client's settings is not set to maximize the Data to save your Mobile Data block.
