The problem

An address without a person is dead weight.

Elsewhere

A signup or a reply from an unknown address can't be routed, scored or personalized. Enrichment vendors join it against a stale table and give up entirely on personal domains.

At Mozart

Mozart resolves the address live and answers only above its confidence bar. 2 credits when a profile is delivered, nothing when it isn't.

The mechanism

From an address to a person.

1

Resolution

The address is resolved live against public professional signals, not joined against a stored table.

2

Confidence

Candidates are scored from 0 to 1. At 0.8 and above, the profile page itself corroborated the identity, and measured precision is 100%.

3

Delivery

Above the bar: URL, name, headline, company, 2 credits. Below it: nothing, 0 credits.

Side by side

Resolved against joined.

Questions, answered whole

Confidence, price, and misses.

Does it work on personal addresses?−

Yes, gmail.com included. The lookup targets the person behind the address, not just the domain, which is what makes signup enrichment possible.

Why 2 credits?+

It's the most expensive call in the catalog and the most precise: 100% above 0.8 confidence on a thousands-email ground truth. You pay only when a profile is delivered.

What does the confidence score mean?+

At 0.8 and above, the profile page itself corroborated the identity: safe to use unattended. Between the delivery threshold and 0.8, the response flags to_verify, so give it a glance before acting on it.

What comes back on a miss?+

Nothing billable. Misses carry an error code naming the cause and cost 0 credits, like everywhere else on Mozart.

100% above 0.8.
Below it, 0 credits.

Put a face on every address that matters.
