This page shows how to add Addressfinder's email verification service to a custom form.

JavaScript snippet

This is the simplest way to add email verification to your website. It only takes a few minutes.

Copy the code snippet below and update the addressSelector and licenceKey with your values, then add it within the <body> tags in your webpage - ideally just before the closing </body> tag.

<script>
(function (d) {

  // ADDRESSFINDER EMAIL VERIFICATION
  // https://addressfinder.com/email-verification

  var conf = {

    addressSelector: "input[type=email]",

    licenceKey: "ADDRESSFINDER_DEMO_KEY",

    check: "domain,connection"

    rules: {
    },
  };

  d.addEventListener("DOMContentLoaded",function(){if(d.querySelector(conf.addressSelector)){var e=d createElement("script");e.src="https://api.addressfinder.io/assets/email/v2/widget.js",e.async=!0,e.onload=function(){new AddressfinderEmail.Email.Widget(conf.addressSelector, conf.licenceKey, conf)},d.body.appendChild(e)}});
})(document);
</script>

Once the snippet is added, email verification will automatically start working with your form fields. You can further customise the verification service by adding rules.

Step-by-step guide

You should have a working web form containing an email address field.

  1. Copy and paste the code snippet at the bottom of your webpage before the closing </body> tag.
  2. Replace the value of addressSelector with the ID attribute of your email field (e.g. #email_address). You can also use a CSS selector such as input[type=email] or input[name=email_address].
  3. Replace the value of licenceKey with your credentials, you can find it in the Portal.
  4. If you prefer a faster check instead of the default full verification, change the value of check from domain,connection to domain.
  5. Customise the verification service settings by including advanced rules (optional).
