Overage notifications via email and MyKinsta messages are enabled by default on all accounts. You can customize the notification method (email, MyKinsta, or both) in your User Settings in MyKinsta.
Learn more about how overages work at Kinsta.
Upgrading your plan will not reset overage notifications for that billing cycle. If you receive a notification, upgrade your plan, but then exceed your plan limits again during the same billing cycle, additional notifications will not be sent out. To prevent exceeding limits after an upgrade following a notification, we recommend checking in MyKinsta (MyKinsta > Dashboard > Resource usage) regularly to keep an eye on your resource usage.
