Why is the _ke parameter breaking my download link?
The _ke parameter is automatically appended to all URLs that appear in your emails. This added tracking should not slow load times or break links due to its placement within the URL.
However, if you are using URLs that contain query parameters to inform your server to automatically download a file, the _ke parameter could cause your link to break. In order for the download to function properly, either toggle off _ke parameters in your account or configure your server to ignore this parameter. As of now, you can only toggle off _ke across your account; you can not turn it off for individual campaigns.
