How does Acoustic Campaign partner with Amazon for asset hosting?

You can upload assets, including images, to Acoustic Campaign for content hosting. After you upload an asset to the asset library, the asset can be referenced in your email messages. When Acoustic Campaign generates email as part of the send process, the assets are inserted by Acoustic Campaign by embedding a URL that references the asset into the message.

The URL in the email body references the client content on the Amazon system. The client content ultimately resides on Acoustic Campaign content servers, but the Acoustic Campaign content servers are only intended to be accessed by Amazon servers to pull and serve the content. When Amazon retrieves content from Acoustic Campaign, Amazon caches that content within the Amazon network so that future requests are served by Amazon directly. When a client sends an email and the recipient opens it, the recipient email program or browser fetches the assets from Amazon. The email body is sent directly from Acoustic Campaign mail servers to the recipient's mail server and is not hosted by Amazon.

Acoustic Campaign uses Amazon as a content delivery network (CDN) provider for several reasons. By using Amazon as a CDN, Acoustic Campaign takes advantage of the extensive, distributed Amazon content network, which moves the content closer to recipients. This improves the performance by which recipients can download the content. Because the Amazon network is extensive and distributed, capacity to handle the content demands from Acoustic Campaign emails is never an issue. By using Amazon to serve the email assets, it offloads the Acoustic Campaign network and server resources. This allows Acoustic Campaign resources to be more responsive and used for other purposes, such as client UI access to Acoustic Campaign, API access, and recipient click-through processing.

By using the Amazon network, Acoustic Campaign also provides a level of separation from Acoustic Campaign that can improve the uptime that recipients experience. If Acoustic Campaign content systems become unavailable temporarily, the Amazon network continues to serve content requests from recipients because the content is cached within the Amazon networks.
