Realtime Email Validation for Webflow Forms
As a Webflow designer or marketer, your forms are critical for lead generation and user interaction. Ensure every submission contains a valid email, eliminating junk leads and streamlining your data collection process.
The problem
Webflow forms are powerful tools for capturing leads, sign-ups, and inquiries. However, they are frequently targeted by bots and individuals who submit fake or incorrect email addresses. These invalid submissions clog your inbox, inflate lead counts with useless data, and waste valuable time as your team attempts to follow up with non-existent contacts. This directly impacts the efficiency of your sales and marketing efforts, diverting resources from genuine engagement to sifting through garbage data.
Relying on unvalidated email submissions from your Webflow forms leads to poor data quality in your CRM or email marketing platforms. When you send follow-up emails to invalid addresses, you risk high bounce rates, which can damage your sender reputation and affect deliverability for all your campaigns. Furthermore, inaccurate lead data prevents effective personalization and segmentation, undermining your ability to nurture prospects and convert them into customers, ultimately costing your business revenue and valuable time.
How Verifyr solves it
Concrete example
const emailInput = document.getElementById('email-field');
emailInput.addEventListener('blur', async () => {
const response = await fetch('https://api.verifyrhq.com/validate', {
method: 'POST',
headers: {'Content-Type': 'application/json', 'X-API-KEY': 'YOUR_KEY'},
body: JSON.stringify({ email: emailInput.value })
});
const data = await response.json();
if (data.status !== 'valid' || data.disposable) {
emailInput.setCustomValidity('Please enter a valid, non-disposable email.');
emailInput.reportValidity();
} else {
emailInput.setCustomValidity(''); // Clear error
}
});
