One audience is not one list. Split it by email status first, then spend records only on the group you will send to. Connect https://api.leadocean.io/mcp (setup is on the MCP page) and paste the prompt below into Claude or any MCP client.
The prompt
I want VPs of Sales in the US, split by email status.
1. Call leadocean_list_enum_values for email_status so you use exact strings.
2. Call leadocean_count_leads three times with jobLevel VP, jobFunction Sales & Business Development, country US, facets=false:
a. emailStatus verified (send now)
b. emailStatus catch_all_valid and catch_all (send in small batches)
c. emailStatus risky, unknown and untested (verify before sending)
3. Give me a table: group, filters, count.
4. Tell me which group to pull first.
5. Do not call any tool that spends records.What it resolves to
| Filter | Value |
|---|---|
| jobLevel | VP |
| jobFunction | Sales & Business Development |
| country | US |
| emailStatus (send now) | verified |
| emailStatus (small batches) | catch_all_valid, catch_all |
| emailStatus (verify first) | risky, unknown, untested |
Never send to invalid, spam_trap, abuse or disposable. The prompt leaves them out on purpose.
How many match
Counts run on 2 October 2026 for jobLevel VP, jobFunction Sales & Business Development, country US. Each count filters on emailStatus, so none of them is the default mailable count.
| Group | emailStatus filter | People |
|---|---|---|
| Send now | verified | 27,093 |
| Small batches | catch_all_valid, catch_all | 88,243 |
| Verify first | risky, unknown, untested | 147,527 |
A search count of verified is an upper bound. Enrichment confirms each address, and that answer wins. A person can show as verified in search and come back untested on enrichment. As a filter, catch_all also matches catch_all_valid, so the second group already holds both. Untested means nobody has checked the address yet, and LeadOcean lists it as the largest status group.
What you get back
Search rows carry the fields below. These are placeholder values, not real records.
| Title | Company size | Industry | Country |
|---|---|---|---|
| VP of Sales | 51-200 | Software Development | US |
| VP, Business Development | 201-500 | IT Services and IT Consulting | US |
| Vice President, Sales | 11-50 | Marketing Services | US |
Variations
- Add "emailType work" to each count to split work addresses from personal ones.
- Change the audience to "Directors of Marketing in GB" and rerun the three counts.
- Ask for a fourth group, role, and have Claude explain why shared mailboxes like info@ sit outside your send list.
