About MailShield ‑ Email Validator
Bad email addresses cause failed deliveries, chargebacks, fake accounts, and support tickets. Email Risk Guard checks every email at checkout and blocks the risky ones before the order is placed. It rejects disposable email domains, enforces your custom blocklist, and catches common typos, suggesting the correct domain so customers can fix it. Each order can also be scored after checkout, tagged by risk, and noted for your team to review before shipping. Block disposable and temporary email domains at checkout Catch common email typos and suggest the correct domain Enforce your own custom list of blocked email domains Auto-tag and add risk notes to suspicious orders after checkout Email alerts when a risky order comes through Show more Show less
