Hey Product Hunt! I'm the founder of Sealch Pro. I was spending $500+/month cleaning email lists with premium verification tools. The thing is, email verification is not complicated technology — it's an SMTP handshake that checks if a mailbox exists. But the market charges $5-8 per 1,000 emails for it. So I built my own infrastructure and launched Sealch Pro at $0.35 per 1,000. Same SMTP verification, same accuracy, fraction of the price. How it works: paste your list or upload a CSV, we connect to the recipient mail servers and check each address in real time, then you download segmented results — deliverable, risky, and invalid as separate CSVs. A few things we do differently: → Unknown results are free. If the mail server doesn't respond, you're not charged. → PAYG credits never expire. Buy once, use whenever. → Disposable emails are detected and flagged at no cost. → REST API included on paid plans. Most teams integrate in 20 minutes. Free 7-day trial with 100 verifications per day, no credit card needed. Would love for you to try it and tell me what you think. Happy to answer any questions about how email verification works under the hood!
