I’ve been learning and experimenting, so I decided to build a small tool called Email Cleaner.
It’s a simple project, but it helped me practice validation logic, error handling, and working with external checks.
I’m sharing it here because I’d love to get feedback from more experienced developers.
🧹 What the tool does
The Email Cleaner scans a list of email addresses and removes or flags:
invalid or malformed emails
non‑existent domains
disposable / temporary emails
spam‑trap domains
role‑based addresses like info@, admin@, support@
The goal is to improve deliverability and reduce bounce rates.
🛠️ How it works
The tool uses a combination of:
syntax validation
domain (MX) checks
mailbox‑level verification
simple filtering rules
I tried to keep the code clean and readable so it’s easy to understand for beginners
Here’s the project if you want to check it out:

🙏 What I’d love feedback on
I’m still learning, so any advice is welcome.
Specifically, I’d appreciate thoughts on:
code structure
performance
validation accuracy
naming / organization
ideas for new features
Even small suggestions help a lot.
💬 Thanks for reading
If you take a moment to look at the project, thank you — I really appreciate it.
I’m trying to improve step by step, and feedback from the community means a lot.
If you want, I can also write:
a shorter Dev.to version
a more technical version
a more beginner‑friendly version
a version with screenshots
Just tell me what style you want.
