Hi everyone 👋

I’d like to share a plugin I recently developed for Mautic 5.2 that integrates with [UseBouncer.com](http://UseBouncer.com) for email verification.

💡 What it does:  
This plugin allows you to validate email addresses directly within Mautic, helping to reduce bounce rates and improve overall deliverability.

⚙ Key features:

- Integration with UseBouncer API

- Batch checking of existing leads

- Automatic verification each time a new lead is created (when enabled)

- Helps maintain a clean and reliable contact database

🎯 Why I built this:  
While using Mautic, I felt there was a gap in native email verification tools. This plugin aims to automate that process and make campaigns more efficient.

👨‍💻 Looking for feedback!

- Ideas for improvements

- Feature suggestions

If you’re using Mautic and care about email deliverability, I’d love to hear your thoughts!

Thanks 🙌
