Show HN: MailShrimp – validate email lists with risk level and confidence score

Hi HN,

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.
