About SMTP Testing

This tool helps you test SMTP server configurations before using them in production. Select a provider from the dropdown or enter custom settings.

Note: This tool runs client-side. For security, actual SMTP testing requires a backend API endpoint. Credentials are never stored and are only used for the current session.
