I recently launched MailShrimp, a tool to validate email addresses and prevent bounces — but with a twist: it returns both a risk category (valid, risky, invalid) and a confidence score (e.g., 0.93).
It performs:
Syntax & format checks
DNS / MX resolution
SMTP verification (with proxy fallback)
Disposable & catch-all detection
Score & classify each email
It’s designed to be:
Fast Clear (human-readable results + exportable data) Dev-ready (API coming soon)
You can paste emails or upload a CSV to test. Would love your thoughts or suggestions.
