Email verification
Finally give your CRM the spring clean it deserves
Ensure every email you collect is genuine and able to receive mail. Check and validate in real-time, or do a bulk upload to clear the cobwebs.
Reduce campaign bounce rates with in-form validation
In-form email verification goes well beyond just checking if the email format is correct. Check each email is accurate, the supplied address is known and its domain is set up to receive mail.
Sharpen up the accuracy of your CRM
Your CRM is only as good as the data that goes in, so make sure you’re really getting what you expect. Enhance your email form field by easily customising filter settings to restrict disposable, catch-all or group email addresses.
Fix historical headaches with bulk verification
Upload a CSV of your email address database, and we’ll verify that each one is valid and correct, format it consistently, and attach its associated metadata. This includes whether it’s a group email, disposable, and whether the email is verified.
How does it work?
The email verification service performs 4 checks when an email address is sent to be validated.
Syntax checks
Verifies if the email address is formatted correctly. An email address must have a username followed by the @ symbol and a domain with a valid suffix such as .com, .org or .net.
Domain checks
Verifies if the domain is configured with an MX record pointing to a valid mail server to check if it can send and receive emails.
Server checks
Verifies if the email address is registered on the mail server by checking the SMTP connection. This makes sure that the address exists and is accepting incoming emails.
Rules checks
Verifies if the email address matches your filter settings. For example, you can only allow non-disposable addresses, restrict catch-all and group emails, etc.

Installation
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 emailSelector and licenceKey with your values, then add it within the <body> tags in your web page - ideally just before the closing </body> tag.
<script>
(function (d) {
var conf = { addressSelector: "input[type=email]", licenceKey: "YOUR_ADDRESSFINDER_KEY", rules: {}, check: "domain,connection" };
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.
