The "RESET CLIENTS" button allows you to force a cache refresh on ALL CLIENTS when they visit the site again.
That's useful if:
1) you are testing a campaign and need to clear the cache without having to reset cookies over and over
2) you want to make sure that campaigns are visible to users even if they joined previously
A/B Testing your campaigns with Drop-a-Deal is simple!
All you need to do is create various campaigns and enable them at the same time.
The system will take care to alternate them by assigning a different campaign to each new visit.
If you are A/B Testing colors and text, there is a convenient CLONE button that allows you to clone campaigns to apply changes.
