Our plugin will be useful to those who are working every day to increase conversion in email mailings and want to decrease bounce rate or accept only real users of all submissions. We will also be useful to those who want to know who is behind that email.
We created a plugin that gives the most accurate data, reachable leads, and which will only accept email addresses from users who have submitted valid emails through any type of form.
At the moment we integrate with: 
* WP-forms 
* ACF 
* Contact Form 7 
* WooCommerce 
* Elementor 
* Mailpoet
You can install and use the plugin by adding an API key, generated from the account <a href="https://www.mailcheck.co" rel="nofollow ugc">free account</a>. 
We aimed to help and make sure you have accurate list of the real users
