As answered by people managing Draft and Check and Flex Software.
Draft and Check's answer
Node.js and TypeScript with a Fastify API, SQLite for storage, Dockerized on an EU (Belgium) server behind Caddy, Stripe for billing, and Cloudflare for delivery. Verification is a custom pipeline of DNS/MX lookups and a direct SMTP client for the mailbox probe.
Draft and Check's answer
It runs a real SMTP mailbox check on every address, connecting to the mail server to confirm the inbox exists, with catch-all detection, not just syntax and DNS. And it is honest: when a mailbox genuinely cannot be confirmed it returns "unknown" instead of a false "deliverable." Credits are pay-as-you-go and never expire, with no subscription.
Draft and Check's answer
It is typically 3 to 4 times cheaper per verification than incumbents like ZeroBounce, with credits that never expire and no monthly subscription. You still get real SMTP verification and catch-all detection, a clean REST API, and honest verdicts. Start with 100 free credits, no card required.
Draft and Check's answer
Developers adding email checks to signup and checkout flows, growth and sales teams cleaning cold-outreach lists, agencies and recruiters, and anyone sending email at volume who wants to protect their sender reputation.
Draft and Check's answer
Draft and Check was built by SovereignShield BV out of a simple frustration: most verifiers either lock you into subscriptions or return optimistic "deliverable" results that still bounce. We wanted verification that is honest about what it can and cannot confirm, priced fairly, and simple to wire up, so we built a deterministic pipeline that tells you the truth, including when the answer is "unknown."
