Certified Marketing Cloud DeveloperDemo

A developer built an email that uses the @subjectLine variable for its subject line. After revisions, the developer declared @subjectLine in multiple places within the email, including:

• %%[ SET @subjectLine = 'Enjoy 10% off today' ] %% declared at the top of the HTML body
• %%[ SET @subjectLine = 'Enjoy 15% off today' ]%% declared at the top of the Text body
• %%[ SET @subjectLine = 'Enjoy 5% off today' ] %% declared at the bottom of the HTML body
• %%[ SET @subjectLine = 'Enjoy 20% off today' ]%% declared within the Subject Line

Which subject line will be used at deployment time?
