How is your data traffic calculated?
At Topol.io, we use Google Cloud Storage to keep and store your data. The overall number of traffic usage means the amount of data transferred during certain period. In other words it means how many images have been downloaded and what is their size.
Formula: Size of images included in an email * Emails sent * Open rate
Hosted image delivery prices are measured in MBs. The formula for calculating MBs is dividing the amount of KBs by 1024. To get the GBs amount, divide MBs by 1024 again.
As an example, if you sent an email with 5 images that are 50KB each, delivered it to 50,000 people, with a total open rate of 50%:
5 * 50KB * 50,000 * 0,5
Traffic included in subscription plans
