The prompt
Find marketing directors at advertising and marketing agencies in the United States.
1. Call leadocean_list_enum_values for industry and pick the advertising
and marketing agency values.
2. Call leadocean_count_leads with jobFunction Advertising & Marketing,
jobLevel Director, those industries and country US.
3. Tell me the count and the filters you used.
4. Do not call leadocean_search_leads until I say go.What it resolves to
| Filter | Value |
|---|---|
| jobFunction | Advertising & Marketing |
| jobLevel | Director |
| industry | Advertising Services, Marketing Services, Marketing and Advertising |
| country | US |
"Agency" is not an industry value, so the prompt maps it to the three advertising and marketing strings. Enum values are exact strings, which is why step 1 looks them up. Advertising Services holds 18,581 of the matches, so it carries most of the list.
How many match
21,708 mailable people matched on 2 October 2026. Filters: jobFunction Advertising & Marketing, jobLevel Director, industry Advertising Services, Marketing Services or Marketing and Advertising, country US.
Mailable means verified, catch_all_valid or catch_all, the count_leads default. The count is free. The facets show 5,703 sit at companies with 11-50 employees and 5,160 at 1-10. Set employeeRange before you write copy: a marketing director at a 20-person shop buys differently from one at 10,000.
What you get back
Search rows carry the fields below. These are placeholder values, not real records.
| Title | Company size | Industry | Country |
|---|---|---|---|
| Director of Marketing | 11-50 | Advertising Services | US |
| Marketing Director | 51-200 | Marketing Services | US |
| Director, Brand Strategy | 1001-5000 | Marketing and Advertising | US |
Variations
- Add "only companies with employeeRange 51-200 and 201-500" to skip the micro shops and keep agencies with a dedicated marketing lead.
- Swap jobLevel Director for VP to reach heads of marketing at larger agencies.
- Change country to GB and ask Claude to count again before searching.
