CDN short for Content Delivery Network is a way of hosting and handling website files. CDN decreases the load time of our website content by distributing it over a geographically-diverse content delivery network covering North America and Europe.
When users open your emails with remote images, the bulk of the response time is due to content download such as images, style sheets, and scripts. When you are using our Managed CDN Hosting service, however, your visitors will download that content from the nearest available server on the CDN network, resulting in significantly faster response times.
