Draft & Check does the same real mailbox verification the big services do, without the subscription, the expiring credits, or the guesswork. Pay only for what you check, and get an honest answer every time.
Pay-as-you-go, one credit per verification, no monthly subscription and no reset. Buy a pack, use it whenever, the balance is still there next quarter. You are not renting access; you own the credits.
Every address comes back as deliverable, risky, undeliverable, or unknown, with a 0 to 100 score. When a mail server declines the probe and the mailbox genuinely cannot be confirmed, we return unknown instead of a hopeful "deliverable." A verdict you can trust is worth more than a green checkmark that bounces.
Not just syntax and DNS. We connect to the mail server, check the mailbox exists, and flag catch-all domains that accept everything. Disposable and role addresses are caught too, and obvious typos get a "did you mean" suggestion.
One REST call, JSON in and JSON out, single or batch up to 1,000 addresses. Infrastructure is EU-based and the addresses you submit are processed transiently, not stored or sold, which keeps GDPR simple.
