Apollo.io
Apollo is the default choice for a small sales team that wants database, sequencing and dialler in one subscription without a ZoomInfo contract, and the agent layer now does the list-building and first-draft outreach that used to need a separate tool. The catch is the credit meter: AI research, enrichment and exports all draw from a pool that resets monthly, so the sticker price is the floor, not the bill.
Pros
- Database, sequencing, dialler, enrichment and meeting booking in one tool at $49 per user
- A real free plan for light use, with no card required
- MCP server, Chrome extension and Apollo Anywhere put the data inside Claude, ChatGPT, Gmail and the CRM
- Agents trained on your ICP and playbooks handle list building and first drafts
Cons
- Credits reset every cycle and do not roll over, and add-on credits bill immediately and recur
- Data accuracy varies by region and seniority, and bounces still eat sender reputation
- Price cards on the pricing page load client-side; the annual discount is not stated
- API access, SSO and advanced security are reserved for the Custom tier
