Previewing merge tag personalization in Builder
Once you've set up your ESP merge tags and added merge tags to an email in Litmus Builder, you can preview different variations of personalization quickly and easily using the Personalization tab of Litmus Builder.
The Personalization tab is available from the left-hand pane of both the code and visual editors. Click on Personalization and you will see a list of all merge tags included in your email.
Each tag has an input field where you can enter different values and see how your email content and design changes in the right-hand preview pane.
Coming soon: we are also rolling out the ability to run email previews with personalized variations. When this feature is available in your account, running previews in the Email Previews tab in the preview pane will also include any values entered in the Personalization tab.
Note: for merge tags to appear on the Personalization tab, they must be configured first in your Personalization settings.
