The industry's dirty secret

We verify catch-alls. We just never bill a guess.

When a domain accepts every address, most tools bill you a guess marked ‘valid’, or give up. Mozart runs its deeper signals on catch-alls too, and returns a result only when it's highly probable. Below that bar: no result, and nothing billed.

Questions, answered whole

Ask us the hard ones.

How does Mozart handle catch-all domains?−

We verify them too. A catch-all domain accepts every address, so a surface check proves nothing. Mozart runs its deeper signals on it and returns the address only when it's highly probable. Below that bar we return nothing, and the held credit goes straight back to your balance. You never pay for a guess.

How accurate is the email finder?+

96% precision on returned addresses, measured on +15 000 real campaign leads. What we cannot prove comes back as not-found, and we tell you which.

Where does Mozart's data come from?+

Nowhere it could go stale. Mozart holds no stored email database and buys from no data provider, so you never receive a contact that was scraped two years ago and never re-checked. Every result is established live, at the second you ask, from DNS, MX, SMTP and Microsoft 365 signals, then forgotten. Your lists never leave our infrastructure.

Is the free plan a trial?+

No. You get 50 credits at signup, no card, no expiry. They follow the same rule as paid credits: only proven results are billed.

Is Mozart GDPR compliant?+

Yes. Mozart is made in France, processes B2B professional data only, and queries no third-party provider. Your lists never leave our infrastructure and are never resold.

Can I use every tool through the API?+

Yes. Every tool on this site runs through one API key, single or bulk, with the same billing rule. Responses carry billable and charged fields, so your accounting can mirror ours to the line.
