What did GPT-5.6 Sol, Terra and Luna unlock that made your launch possible?

We used GPT-5.6 to solve the biggest pain point in email verification: catch-all domains. Standard SMTP probes struggle with catch-all mail servers because they accept all incoming requests regardless of whether the mailbox exists. GPT-5.6's low-latency inference allows us to run real-time predictive risk scoring on these domains during our 200ms verification pipeline. By analyzing historical domain behavior, MX server configurations, and address syntax patterns in real-time, we can accurately predict whether a catch-all email is a legitimate inbox or a risky drop—protecting our users' sender reputation without slowing down our API.

Hey Product Hunt 👋 I'm Sadnan, founder of LeadPure. When we were building outbound campaigns, one thing always bothered me: most email verification tools are ridiculously expensive for what they do. If you're a lean team or solo founder, paying high monthly fees just to clean a list feels like a tax on growth. So we built LeadPure to be affordable, fast, and straightforward. Our main focus is email verification. Instead of relying on old cached data, LeadPure runs a live 30-step SMTP check directly against recipient mail servers. It checks if the inbox actually exists, filters out spam traps, and flags catch-all domains—protecting your domain health before you hit send. We also added a simple lead finder on the side, so if you need to discover a contact's email by name and domain, you can do that in the same workflow. We're giving everyone 500 free credits to test it out on your own lists. Would love to hear your feedback on the tool and pricing!
