emailval — Email Validation API
Email validation API — 10× cheaper than ZeroBounce
emailval runs every email address through a five-layer validation pipeline and returns a deliverability score from 0 to 100. Layers: syntax check → MX record lookup → disposable domain detection (350k+ domains) → catch-all probe → SMTP mailbox verification. Pricing: $0.0008 per email via Stripe. No monthly fee, no contracts, no minimums. 10× cheaper than ZeroBounce ($0.008) and 8.7× cheaper than NeverBounce ($0.007). Self-serve: pay with Stripe, get your API key by email in seconds.
Hey Product Hunt! 👋
I'm Dmytro, the developer behind emailval.
The problem: email validation APIs are expensive. ZeroBounce charges $0.008/email, NeverBounce $0.007. If you're cleaning a list of 1 million addresses, that's $8,000. Most of that cost isn't justified by the underlying work.
So I built emailval — a five-layer validation pipeline at $0.0008/email. Ten times cheaper.
How it works technically:
Layer 1: RFC 5321/5322 syntax check (<1ms, no network call)
Layer 2: Async DNS MX lookup with Redis caching
Layer 3: Checked against 350,000+ disposable domain blocklist (updated weekly)
Layer 4: Catch-all detection via SMTP probe with random UUID address
Layer 5: Full EHLO → MAIL FROM → RCPT TO handshake — no email is ever sent
The result is a deliverability score 0–100. 100 = mailbox confirmed. 60 = valid but provider (Gmail/Outlook) blocks SMTP verification. 20 = disposable or catch-all. 0 = invalid.
Self-serve: pay with Stripe → API key arrives by email in seconds. No sales call, no trial form.
Happy to answer any technical questions about the SMTP layer or how I handle catch-all detection. It's more interesting than it sounds 🙂
