# Find a work email address – without guessing.

First the person – name, role, company, LinkedIn –, then the address from data providers, then the check. There is no guessed address: Hunter measured in 2026 that 76 percent of email addresses produced by language models are invalid.

## Inputs and connections

First name, last name and company or domain – or a LinkedIn URL, or the other way round an address whose owner you want to know. From Claude Code, ChatGPT or n8n.

Every step needs the agent's sign-in (or a key); address and check also need workspace credits.

## Steps

1. **Identify the person** (Your agent · by call). find_person returns candidates with role, company, LinkedIn and a confidence (high, medium, low) – no credits and no contact data. It also works in reverse: the person behind an address.
2. **Find the address** (ListPlus · by call). enrich_records asks several providers in turn. The price comes first in the answer (expected and at most); only a hit is charged.
3. **Check deliverability** (ListPlus · by call). verify_email confirms the mailbox exists. Catch-all stays as a hint.
4. **Keep it** (Your agent · by call). The result goes back to your agent; in a list you shared with it, the row is filled in place – with source and date per value.

## Expected sample result

find_person names Mia Winter, Head of Buying at HelioWorks, confidence high. enrich_records finds an address (one hit, charged once), verify_email answers valid.

## Costs and boundaries

The person lookup costs no credits. The address from name and company: expected 2.39 credits, at most 9 credits ($0.32 on Pro) – charged only on a hit. The check 0.3 credits.

The person lookup deliberately returns no email – contact data only comes from enrichment and costs only when found. An address is a provider's hit, not proof the person still works there.

## Agent prompt

Find the work email of Mia Winter at HelioWorks. First find_person: show me the candidates with role and confidence. Ask me before you start enrich_records and name the price. Verify the found address with verify_email. Never guess an address.
