🚀 Built for the community: A free API to filter out invalid & disposable emails!

I recently struggled with cleaning up my marketing list—most email verification services were either expensive subscriptions or felt a bit sketchy (who knows if they’re collecting my data? 🤔).

So, I built my own API to quickly filter out invalid and disposable emails, and I’m making it available for free to help others facing the same issue.

No shady practices. No hidden fees. Opensource. Just a simple, reliable tool for the community.
