Will I receive low quota alerts with the Email Hippo WHOIS API service?

This article describes when/how you will know when your quota is running low.

Yes, similar to our email validation services, when your WHOIS quota is running low you will receive email notification

We will let you know when your quota drops to 10% and 5% of your monthly subscription plan. 

When you receive these notifications we recommend upgrading your subscription to next subscription plan level if you do not think your quota will last until your subscription renewal date.
