Frequently Asked Questions

Find quick answers to your questions about our pricing and plans.

01

Does the widget have any limits?

Each internet IP (or each single website visitor) can validate 20 emails per day using your widget. This is a security measure to protect your credits from an abuser. In this case, the widget shows “You performed many validations” error message.

02

How many emails each visitor can validate?

Each website visitor is allowed to validate 20 emails per 24 hours.

03

How can I create my own functions while using the widget?

The widget supports Event Listener. It means if you are familiar with the JavaScript language, you can write your own functions and enhance the integration.
