Email Guard scans every customer in your Shopify store and flags addresses that won't deliver: typos in the domain (gamil.com, hotnail.com), invalid syntax, disposable inboxes, and role-based addresses. Once detected, you can fix them with a single click, tag them and even trigger Flow automations, restoring deliverability for transactional emails, marketing campaigns, and abandoned-cart recovery without ever leaving the Shopify admin. Built for stores where every customer matters!

• Scan customer segments, find common email typos and fix them in bulk.
• Automate email fixing, detect common patterns and get smarter with usage.
• Recover customer emails for campaigns and automations.
