"Update Proof & Previews" functionality

Maintain full control over which version of your email campaign your stakeholders see with the Update Proof & Previews (or Update Previews & QA for customers without Proof) option in Builder.

Editing your email in Builder? Once you’re happy with your updates, send the updated HTML to Proof and the Previews & QA tab, ensuring that everyone on your team is always looking at the most updated version. To do this, simply click the Update Proof & Previews tabs (or Update Previews & QA for customers without Proof) button.

Once you click the button, your email will be auto-saved and the most updated HTML and subject line will be viewable in Proof and the Previews & QA tab. By doing this, a new version of your email test will be created. It works the same way as if you clicked New version button in Proof. You can still review previous iterations/versions.

Something to keep in mind: 

• Sending HTML from Builder to Previews & QA is not as accurate as sending into Litmus from your ESP.
