Whether you run a WooCommerce store, blog, membership site, or business website, NoorSMTP helps ensure that password resets, contact form submissions, order receipts, and admin notifications reach the recipient’s inbox. ### 🚀 Key Features * **Custom / Standard SMTP Provider:** Connect to any SMTP host (including Sendgrid, Mailgun, Amazon SES, Brevo, Postmark, Yahoo, Zoho, or your web hosting email server) with custom port, authentication, and SSL/TLS encryption. * **Gmail API with Secure OAuth 2.0:** Send emails directly through Google’s official Gmail API without storing your Google account password or creating less secure app passwords. * **Email Delivery Logging:** Automatically track outgoing emails with delivery status (Sent / Failed), recipient, subject, mailer used, date, timestamp, and technical error diagnostics. * **Instant Delivery Test Tool:** Send test emails to any recipient address and view real-time server responses and debug logs to verify setup in seconds. * **Safe Data Management:** Your email logs and settings are preserved safely on plugin deactivation or uninstall by default. A dedicated setting with user confirmation allows full data removal only when explicitly chosen. * **Modern & Clean Interface:** Built specifically for WordPress administrators with an intuitive, accessible dashboard. ### 🌟 Need Advanced Features?

Email logging uses indexed database tables optimized for quick lookups. ### What happens if I uninstall the plugin?
