You can use this feature independently of the widget at any stage of your process without compromising the user experience. With Zencaptcha's reliable detection of 99% of temporary and disposable email addresses, you can ensure that your marketing campaigns are targeted to the right audience, avoiding wasted resources and maximizing your ROI.
