Apollo.io

by Apollo

ZoomInfo

by ZoomInfo

Pros

• ✓240M+ verified contacts and 30M+ companies with filters for funding stage, technographics, hiring signals, intent data, job change alerts, and AI-powered Lookalikes (BETA), all without a separate data provider.
• ✓Autonomous sequence execution runs outreach end-to-end once configured: Apollo sends, waits, follows up, and logs to CRM without per-step human approval. AI Assistant (introductory free on paid plans) provides conversational access to prospecting data and campaign analysis.
• ✓Publishes a first-party remote MCP server at mcp.apollo.io on every plan including the free one, with prebuilt connectors for Claude, ChatGPT and Perplexity, and CRM sync with Salesforce and HubSpot runs in both directions.

Limitations

• –Usage runs on credits: a verified email is 1 credit, a phone number 8, enrichment 1 to 8 per record and US dialing 1 per 30 seconds, with additional credits bought separately.
• –Organization starts at 3 seats at $119 per user per month on annual billing, and downgrades take effect immediately without mid-term refunds.
• –Apollo's AI policy allows Customer Data to be used to train its internal models, and it publishes no customer opt-out.

Pros
