What Apollo does
Apollo combines prospecting data with outreach operations. Its waterfall enrichment can query partner sources after Apollo’s data, so evaluating it as only a static contact database misses part of the product.
Start with Apollo when your job is finding contacts, reviewing them and running outreach in the same system. Choose by the process you need, not an arbitrary company revenue or sales-team size. Do not buy it on the assumption that a large database guarantees coverage of your particular market.
Pricing: verify the account, then model usage
Apollo’s current pricing page names Free, Basic, Professional and Custom plans. We have not verified a current numeric paid entry price; check the selected plan and billing term before budgeting.
Request a quote or account summary that includes seats, credit allocation, add-ons, renewal terms and the integrations you require. Confirm whether your existing account follows legacy terms. API charges depend on the endpoint, returned data and plan; a rate from another account is not a budget.
Use this calculation for the pilot: allocated subscription cost plus extra credits, external verification and review labor, divided by accepted records. Count failed lookups and discarded records in the numerator. Keep the billing period consistent when comparing a monthly workflow with an annual contract.
Its role in our enrichment workflow
Apollo is an optional source of contact or company data before the Clay and Claude workflow. That workflow’s download contains 20 invented records and runs offline. It does not include an Apollo connector, an Apollo coverage test or a sending integration.
To adapt the process, export only the required fields with stable row IDs. Preserve where and when each fact was obtained. A database field alone does not satisfy the bundle’s exact-quote evidence contract; collect supporting source text separately or mark the fact for review. Do not invent a quotation to make an export pass validation.
Clay is useful here when you need to assemble additional research and exception routes. Claude can extract candidate facts from that text. Neither is a mandatory extra purchase: first check whether your existing process produces acceptable records without them.
MCP and operating limits
Apollo MCP connects assistants to search, enrichment and sequence actions, including on Free. Treat access to an action as a permission to configure carefully, not a reason to automate it immediately.
- A connected assistant can change records or outreach state. Start with a bounded lookup task, inspect the output and require review before writes or sequence enrollment.
- Usage follows the work performed. Check Credit usage, including its MCP/API surface filters. Set a run budget and investigate repeated requests before increasing volume.
- A populated field can still be wrong or stale. Verify role, company match and required contact fields on a sample from your target segment. Keep rejected records out of sending lists.
How to choose
Use the same sample and acceptance rules in our enrichment evaluation guide. Record missing fields, corrections, review minutes and accepted-record cost. Prefer Apollo if its combined process meets those requirements. Read Clay vs Apollo when you need additional research steps or custom gates; add that complexity only when the measured improvement pays for it.
