Draft & Check verifies whether an email address is really deliverable before you send, so your lists stay clean and your sender reputation stays intact.

It runs a full pipeline on every address: - Syntax and DNS/MX checks - Disposable and role-address detection - Typo suggestions ("did you mean gmail.com?") - A live SMTP mailbox probe with catch-all detection

Every address returns a clear verdict (deliverable, risky, undeliverable, or unknown) and a 0 to 100 score. When a mailbox genuinely cannot be confirmed it returns "unknown" instead of a false "deliverable", honest results you can trust.

Pay-as-you-go credits that never expire. Start with 100 free, no card. Single and batch verification via a simple REST API, plus a RapidAPI listing. EU-hosted and GDPR-conscious.

  • Offers reliable delivery with automatic retries and failure handling, improving robustness
  • Saves development time by offering webhooks-as-a-service rather than requiring in-house engineering

Questions & Answers

As answered by people managing Draft and Check and Hook0.

Which are the primary technologies used for building your product?

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.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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."
