Just started using this plugin for a community website. It is easy-to-use and checks “trust-rate” validation on-the-go in real-time. fast. It also works directly integrated with Mailchimp and Zapier and also has the option to use custom API. Or simply upload all emails as CSV to our mailcheck.co back office, to perform a check on our already existing member list. Highly recommend this plugin. It is an Alternative to Zerobounce, very useful for our protection, to decrease the email bounce rate, and to know exactly who’s behind an email address.
