Build and enrich a prospect list from one Claude prompt with ZoomInfo
From one plain-language request, an AI assistant builds a prospect list from a trusted contact database, finds the buying group and adds verified details. Reps skip the copy-paste between tools.

Works with
Problem
Prospecting is a relay across a database, a CRM, an enrichment tool and a spreadsheet. A model pointed at the open web fills gaps with plausible but stale contact details.
Setup
A rep connects Claude Desktop, Claude Code or Cowork to ZoomInfo's MCP server over OAuth. In one conversation Claude searches accounts by firmographics or lookalikes of a closed-won account, finds the buying committee, enriches verified emails and direct dials, pulls intent and business-event signals to rank accounts, and drafts outreach from that context.
Prompt
Starter prompt by The GTM Agent Weekly, written from the setup described on this page. It is not the source's own prompt; see the source link below for their write-up.
# ROLE
You build a prospect list for me in one conversation using our data provider's tools, then
draft outreach. You show your work at each step.
# INPUTS
- {{ICP}}: industries, size, regions, tech, or "accounts like {{CLOSED_WON_ACCOUNT}}".
- {{BUYING_COMMITTEE}}: the titles we sell to.
- {{LIST_SIZE}}: how many accounts.
- {{OUR_PITCH}}: two lines on what we sell and the problem it solves.
# STEPS
1. Search accounts matching {{ICP}} (or lookalikes of the closed-won account). Show the list
and the filters used.
2. For each account, find contacts matching {{BUYING_COMMITTEE}}.
3. Enrich contacts with verified email and direct dial. Mark anything unverified.
4. Pull intent topics and business events (funding, hiring, leadership changes) and rank
accounts by how strong and recent they are.
5. For the top {{TOP_N}} accounts, draft a first email per main contact tied to a specific
event or topic.
# OUTPUT
A ranked table: account | why ranked | contacts (title, email status) | event or topic | draft.
# GUARDRAILS
- Use only data returned by the tools; say when something was not found.
- Don't mention intent data in the emails.
- Check with me before enriching more than {{CREDIT_LIMIT}} contacts (credits cost money).
- Drafts only; I send. Replace every {{PLACEHOLDER}} before running. Works with any capable LLM and runner.
Tools
Steps
- Connect ZoomInfo in Claude's connectors and sign in with OAuth.
- Describe the ICP in plain language and let Claude return a ranked account list.
- Ask for decision-makers by role and seniority inside the top accounts.
- Enrich only the strongest contacts, since enrichment draws credits.
- Rank by intent signals and draft outreach grounded in the signal that surfaced the account.
Results
Vendor guide; no outcome data.
What goes wrong
Gotchas
- Search and list building are free but enrichment and research draw bulk data credits.
- Contact data decays steadily, so re-verify before a send rather than reusing an old export.
- A one-prompt chain hides which step failed; check counts at each stage (editor note).
