How much bandwidth is used?
The communication with the server is designed to consume as little bandwidth as possible by sending the information compressed. However, it depends on how you use the service. If you view many emails containing images or documents, then you will need more bandwidth to download them. If you use the application in “Push-email” mode, you will instantly and automatically receive your emails from your account, because the application is constantly connected to the server. The connection is optimized to reduce network traffic as much as possible. There is an option in the application which shows the amount of data traffic for the current session. In any case, it is advisable to check the prices offered by your internet service provider and see if it is advantageous for you to get an internet flat rate.
