When staggering a Phishing simulation and using multiple templates, it is very important that you consider these points before publishing it. 

1. You must have a minimum of 4 targets per hour for each template that you create. For example, if you choose 4 templates, the minimum guidelines mean that you must have at least 12 targets staggered across 3 hours.
2. If you stagger this exact scenario across 4 hours or more, all users will receive Template 1 from your selection.
