The ability to receive email via smartphone is a Godsend. People no longer have to fire up a laptop and find a Wi-Fi connection to see the new messages in their inbox. The 3G and 4G network makes everything instant. Smartphone can simply remove the phone from their pockets and touch the screen.
There are a couple of tips for those that obtain messages this way. The biggest thing is the push notifications. Smartphone users that receive lots of spam mail should be weary of using the push notification feature. When the push notification is turned on the phone will signal the owner every time a new message is received. This means that all spam mail that doesn’t get caught in the spam folder will alert the owner of a new message. These notifications could warn you every couple of minutes if you get lots of spam mail. People that can’t control spam will want to turn this feature off.
People that use Exchange server mail accounts should also know that the recent mail is the only thing shown in the inbox. You will not be able to access mail from last month through Exchange server accounts on the smartphone.
