Catch the email typo at checkout — save the order

A mistyped email at checkout means a lost order confirmation, a confused customer, and a preventable support ticket. Validate inline and recover the sale in real time.

What goes wrong without email verification

Customers mistype their email at checkout more often than you think — especially on mobile, where autocorrect substitutions go unnoticed. A wrong email address means no order confirmation, no shipping notification, and a customer who thinks their order was lost.

Order confirmation failures generate immediate customer service load: "I never got my confirmation email" tickets are among the most common post-purchase contacts. Each ticket costs $5–$15 to handle — a cost that compounds across thousands of monthly orders.

Bad email addresses on post-purchase flows (review requests, loyalty programs, win-back campaigns) inflate list churn and inflate your monthly cost at ESPs charged per active subscriber.

How emailzeno solves it

emailzeno runs a five-layer verification pipeline — syntax, disposable-domain check, role-address flag, MX reachability, and live SMTP handshake — to give every address a human-readable verdict before you send, sync, or onboard.

Read the API docs
Inline validation with typo correction: The API's did_you_mean field suggests the correct domain when the user types "gmai.com" or "yaho.co" — a one-click fix that saves the order without friction.
Sub-250 ms checkout integration: Low-latency server-side or client-side call that completes well within the checkout form's natural user interaction time. Shopify Plus, WooCommerce, and custom stacks all supported.
Suppress fake orders at source: Disposable-email detection flags orders placed with throwaway addresses — a strong signal for fraud or promo abuse. Route these to manual review rather than auto-fulfilling.

Integration in under 5 minutes

// Server-side order validation (Node.js / Express example)
async function validateCheckoutEmail(email) {
  const response = await fetch('https://app.emailzeno.com/api/v1/verify', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.EC_API_KEY}`,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({ email }),
  });

  const { result } = await response.json();

  return {
    isValid:       result.status !== 'undeliverable',
    isDisposable:  result.is_disposable,
    suggestion:    result.did_you_mean ?? null,
    riskScore:     result.risk_score,
  };
}

Shopify-style checkout validation: call the API on email field blur, surface did_you_mean, block obvious disposables.

E-commerce — common questions

We recommend a risk-tiered approach: hard-block addresses the API flags as "undeliverable"; soft-warn (show a suggestion) for disposable addresses; allow "risky" and "catch-all" through with a secondary confirmation nudge. Hard-blocking disposables catches the majority of promo-abuse patterns without annoying genuine customers who use aliases.

Shopify Plus supports checkout UI extensions where you can call the emailzeno API client-side on blur. For standard Shopify, the server-side approach works via a post-checkout webhook that flags the order before fulfillment. We're building a native Shopify app — sign up for early access.

Never let a verification service become a checkout dependency. Wrap the API call in a try/catch with a 500 ms timeout; if we're unreachable, fail open (allow the order through). Our SLA is 99.9% uptime — but your checkout is more important. The verification catches 99%+ of issues; the rare miss is worth the resilience.
