About the MailShield: Fake Email Blocker
MailShield protects your store by blocking fake email addresses, disposable domains, and temporary email services at checkout. Stop chargebacks, failed deliveries, and fraudulent accounts before they become problems.
The app checks every email address during checkout and rejects risky ones automatically. It blocks disposable and temporary email domains, enforces your custom blocklist, and catches common typos by suggesting the correct domain so customers can fix mistakes instantly.
After checkout, MailShield scores each order and auto-tags suspicious ones with risk notes for your team to review before shipping. You'll receive email alerts when risky orders come through, helping you prevent fraud and reduce support tickets caused by bad email addresses.
