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.
