We built an email validation API because bad leads were quietly killing our campaigns — would love feedback

Hey IH 👋 — founder/team here at Gamalogic, sharing since this community has been a great source of honest feedback for early-stage tools.

The problem we kept running into (and kept hearing from other teams): email lists look fine on the surface, but a chunk of "valid" addresses are actually disposable, role-based, or sitting on catch-all domains that silently bounce later. That quietly wrecks deliverability and skews every funnel metric downstream.

So we built a validation API that does real-time + bulk checks — syntax, MX/DNS, SMTP, disposable and catch-all detection — with a REST/JSON setup so it's easy to drop into a signup form or a cold-outreach pipeline. There's a free tier (500 credits, no card) if anyone wants to test it against their own list.

Genuinely want feedback — what would make something like this a no-brainer for your stack? What have other validators gotten wrong for you?
