How to Find Email Address from Website With Claude

Give Claude a company website and it returns named people with a verified work email at that domain, not a generic info@ inbox. Connect the server at https://api.leadocean.io/mcp first. Setup is on the MCP page.

The prompt

Find work emails for decision makers at acme.com.
1. Call leadocean_count_leads with domain acme.com, jobLevel C-Team and VP,
   emailType work and emailStatus verified.
2. Tell me the count and the filters you used.
3. If the count is above zero, call leadocean_search_leads with the same
   filters and limit 10. Show title, seniority and email_status.
4. Do not search until you have told me the count.

What it resolves to

work means an address at the person's current employer. work_other is a different company, usually a former one, so avoid it here. Enum values are exact strings, which is why Claude checks them with leadocean_list_enum_values.

How many match

2,934,906 people on 1 October 2026. Filters: jobLevel C-Team or VP, emailType work, emailStatus verified, with no domain set.

This is a count of people with a verified work email, not the default mailable count, because emailStatus replaces that default. Adding your domain narrows it to one company. Run the count first: it is free.

What you get back

Search rows carry the fields below. These are placeholder values, not real records.

Variations

• Replace the domain line with a list of ten domains and ask for a count per domain before any search.
• Change jobLevel to Director and add jobFunction Sales & Business Development.
• Drop emailStatus and ask Claude to report the count again, labelled as people with a work email.

Records it spends

The count and enum lookups are free. leadocean_search_leads costs 1 record per person returned, so limit 10 costs 10 records. Free gives you 1,000 records one-off with no card. Pro is $499 a month. See pricing.
