Preview and Test a Web Campaign

This article shows you different ways to preview a web campaign, and also how to test it using a sandbox segment live on your website.


The preview only shows how the campaign will look on the chosen site. Links and widgets will be non-functional as to avoid erroneous clicks/views in the analytics.
