Email Domain Checker

Email Domain Checker is an Office Add-in developed by Bizwind that strengthens email security by notifying users when they attempt to send messages to external (non-company) addresses, helping prevent accidental data leaks. Designed for organizations in finance, healthcare, legal, and other industries where confidentiality is critical, the add-in integrates seamlessly with Outlook for Microsoft 365. It analyzes email metadata in real time to detect external recipients, prompting users to review and confirm before sending. This proactive safeguard supports IT administrators, compliance officers, and employees in reducing the risk of sensitive information exposure.

Key Features:

• Real-time alerts when external email addresses are detected.
• Seamless integration with Outlook on the Web, Desktop, and Microsoft 365.
• Supports data protection initiatives and compliance (e.g., GDPR, HIPAA).

SmartAlert Disclosure:

This add-in uses SmartAlerts to help protect your information. When you send an email to recipients outside your approved internal domains, a warning message is displayed before the email is sent. Internal domains are defined by the user in the add-in settings and stored in your Microsoft 365 roaming settings. The add-in does not alter message content and does not transmit information outside of Microsoft 365.
