About this plugin
Tired of WordPress emails getting lost, marked as spam, or failing to deliver? 0 authentication, replacing the default PHP mail() function.
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.
