Your question is a bit general. To see if you have any email, you need to log into your e-provider. It's the same as logging into any other website. Note: There are 'monitor' add-ons and/or programs that can display that 'You Have Mail.' Warning: Sometimes you may see a popup saying you have mail, but that is just an ad. But sometimes it can lead to malware. It you are not sure, do not access such a popup.
