Mailvalid
Email verification API, 6x cheaper than ZeroBounce
Verify emails at $0.001/email. 6x cheaper than ZeroBounce, 8x cheaper than NeverBounce. Same 95%+ accuracy. Real-time and bulk verification with MX, SMTP, disposable, and catch-all detection. Detailed JSON response with 10+ data points. Webhook support for bulk jobs. Credits never expire. 100 free to start. No credit card required.
Hey PH! I am Sachin, agency founder by day and micro-SaaS builder by night.
I built Mailvalid after a client cold email campaign got their domain blacklisted overnight. The culprit? 30% of their list was invalid. They paid $200 to clean it with ZeroBounce. Way more expensive than it needed to be.
So I built the verification infrastructure myself. After validating it on real campaigns (reduced bounce rates by 90% for early users), I packaged it as an API and opened it up.
Mailvalid does:
- Syntax, domain, MX, and SMTP verification in one call
- Disposable email and catch-all detection
- Bulk list cleaning (async, up to 10k at once)
- Credits that never expire (your $50 credit from today works in 2027)
Why cheaper? No VC-funded bloat. No SDR team. Just the API.
Would love feedback on: the API docs, the pricing model, and whether the response payload has what you actually need in production.
