What if I exhaust my purchased quota limit?
For all products except VWO Insights, all your running tests and data capture will stop upon exhaustion of quota. Automatic extension of quota does not happen.
For VWO Insights, due to our sampling feature, MTU quota is dynamically distributed across the entire month and the user sampling adjusts automatically as per your incoming traffic. So you will never run out of Insights quota. Please check this doc to understand the methodology behind quota distribution.
