Apollo Overview
What is Apollo?
Apollo.io is a sales engagement platform that combines a B2B contact database (~275M+ contacts), email sequencing, dialer, and CRM-style workflows in a single product. It is positioned as the all-in-one alternative to running ZoomInfo + Outreach + a dialer separately.
Apollo Pros
- All-in-one: prospecting + sequencing + dialer in one platform
- Self-serve pricing, sign up and pay by credit card
- Free tier with limited credits, no sales call required
- Strong Chrome extension for LinkedIn
- Larger personal-email coverage than ZoomInfo
Apollo Cons
- Export credits cap aggressively, even paid plans hit limits fast
- Data quality varies; some segments (especially non-US SMB) feel thin
- UI tries to do too much, onboarding curve for new sellers
- Sequencing is functional but trails Outreach/Salesloft on advanced features
Best For
Inside sales teams under 50 reps, agencies running multi-client outbound, and founders who want a single tool to source and sequence prospects without buying a separate CRM.
Apollo Pricing

- Basic: ~$49/seat/month, 200 credits
- Professional: ~$79/seat/month, 1,000 credits + sequences
- Organization: ~$119/seat/month, advanced filters + integrations
