Sounds really useful. Still, I believe Emailable does that, including the scores. Have you tried it?

Thanks!We&#x27;re using a proprietary multi-layered algorithm that combines a series of criteria, checks, and heuristics to assess each email address.It includes:Format and domain-level validations
SMTP-level interaction with fallback logic
Detection of disposable domains, catch-all behavior, and risky patterns
A scoring model that returns both a risk label (valid, risky, invalid) and a confidence score (0.0 to 1.0)
And much more — especially for nuanced edge cases and deliverability signalsUnlike many validators that return a binary result, MailShrimp gives you both a label and a score, so you can decide what’s safe to keep based on your own thresholds.We&#x27;re also focused on speed and usability.
Our logic is designed to handle edge cases often missed by more generic tools.Still early stage — feedback is very welcome!

Neat. What are you using on the backend to verify? How is it different from other platforms such as Emailable?

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 &amp; format checksDNS &#x2F; MX resolutionSMTP verification (with proxy fallback)Disposable &amp; catch-all detectionScore &amp; classify each emailIt’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.
