Advanced Email Validator – Regex, MX & SMTP Check is a powerful email validation component for OutSystems. It ensures that email addresses are correctly formatted, have valid mail servers, and (optionally) exist on the recipient’s mail server. This helps prevent invalid or fake email sign-ups, improves data quality, and enhances email deliverability.

This component leverages C# in Integration Studio to perform a three-step verification:
✅ Format Validation – Uses regex to check if the email follows a proper structure.
✅ MX Record Lookup – Confirms if the email’s domain has a mail server configured.
✅ SMTP Handshake – Connects to the mail server and verifies if the email exists.

By integrating this asset into your OutSystems applications, you can ensure higher-quality user data, reduce bounce rates, and prevent fake sign-ups. 🚀
