About Ninja Test Email
From the official readme · v1.1.1Description
Ninja Test Email is a comprehensive email testing solution for WordPress that helps you verify your site’s email configuration is working correctly. Whether you’re troubleshooting SMTP issues, testing email deliverability, or monitoring outgoing emails, this plugin provides all the tools you need.
Why Ninja Test Email?
WordPress relies heavily on email functionality for user notifications, password resets, contact forms, and more. If emails aren’t sending properly, your site’s core functionality breaks down.

- Developers testing email functionality during development
- Site owners monitoring email deliverability
- Agencies managing multiple WordPress installations
- Anyone who needs to verify SMTP configuration
How It Works
Ninja Test Email integrates seamlessly into WordPress, logging all outgoing emails automatically while providing a dedicated interface for sending test emails. The plugin uses WordPress’s native wp_mail() function, ensuring compatibility with any SMTP plugin you’re already using (WP Mail SMTP, Easy WP SMTP, Post SMTP, etc.).

Frequently asked questions
Does this plugin send emails or just test them?
The plugin does both. It automatically logs all emails sent by WordPress (from any plugin or theme) AND provides a dedicated interface for sending test emails to verify your configuration.
Will this work with my SMTP plugin?
Yes! Ninja Test Email uses WordPress’s native wp_mail() function, so it’s fully compatible with WP Mail SMTP, Easy WP SMTP, Post SMTP, Mailgun, SendGrid, and any other SMTP plugin.
How long are email logs stored?
By default, logs are kept for 30 days. You can configure this in Settings, choosing retention periods from 7 days to unlimited (never delete). The plugin runs a daily cleanup cron job automatically.
Does this slow down my site?
No. The plugin uses optimized database queries, caches results where appropriate, and stores logs in a custom table (not post meta). Email logging happens asynchronously and won’t delay email sending.
Can I use this on a production site?
Absolutely! The plugin is designed for both development and production use. The logging feature helps you monitor email deliverability on live sites, making it easier to catch and fix issues before they affect users.
What if my emails aren’t sending?
If test emails fail, check these common issues: 1. Verify PHP mail() is enabled on your server 2. Install an SMTP plugin (WP Mail SMTP recommended) 3. Check your email logs for error messages 4. Ensure your hosting allows outbound email 5. Test with different recipient addresses
Can I export email logs?
The current version provides log viewing and search. Export functionality can be added via the REST API – use the /logs endpoint to retrieve data programmatically.
Is this plugin translation ready?
Yes! The plugin includes complete internationalization support with 41 translatable strings. All user-facing text uses WordPress translation functions and includes translator comments for context.
Does this work with Gutenberg?
Yes. While the plugin doesn’t provide Gutenberg blocks, it includes a traditional shortcode that works in both the Classic Editor and Gutenberg’s shortcode block.
What happens when I deactivate the plugin?
Deactivating stops the logging and removes the scheduled cron job. Your existing logs remain in the database. To completely remove all data, use the uninstall feature.
Can I delete old logs manually?
Yes. You can delete individual logs from the Email Logs page, or configure automatic cleanup in Settings. Bulk deletion via REST API is also supported.
What PHP version do I need?
PHP 7.4 or higher is required. The plugin uses modern PHP features and follows WordPress coding standards.
