Invalid email addresses at checkout mean lost order confirmations, failed cart recovery, and damaged sender reputation. Verify at the point of entry — before invalid addresses ever touch your database.
From checkout validation to list hygiene, VeriMails keeps your customer data clean and your transactional emails delivered.
Verify email addresses the moment a customer registers or checks out. Return a clear error before form submission if the address is invalid, disposable, or has syntax errors.
Disposable email services like Mailinator and Guerrilla Mail are a common vector for promo abuse and fake accounts. Block them automatically at registration before they enter your system.
Order confirmations, shipping notifications, and password resets are mission-critical. A clean email list keeps your transactional sending infrastructure healthy and out of spam filters.
Cart abandonment campaigns only work if the email address is real. Verify addresses during checkout to make sure your recovery sequence reaches actual shoppers.
Run your entire customer database through bulk verification to identify stale, invalid, and undeliverable addresses before your next campaign or re-engagement series.
Most email service providers charge by list size or email volume. Removing invalid and unengaged addresses reduces your monthly bill and improves engagement metrics — both for pricing and deliverability algorithms.
Integrate verification at checkout, block bad addresses on entry, and run periodic hygiene on your existing database.
Integrate the VeriMails API into your checkout or signup form. One GET request returns a full verification result in under 2 seconds — invisible to the customer.
Use the API response to block disposable addresses, show inline errors for syntax failures, and flag suspicious entries for review before they reach your database.
Schedule monthly bulk verification runs on your full customer list to catch addresses that have gone stale since signup. Keep your list clean on an ongoing basis.
“We added VeriMails to checkout and saw fake account signups drop by over 30% in the first week. Order confirmation deliverability went from 87% to 99%.”Sarah M., E-Commerce Director at Online Retail Marketplace, Germany
