Apollo.io Pros & Cons
Pros
- The most generous free plan in B2B prospecting — unlimited email credits and verified contacts at no cost
- 600,000+ companies using Apollo validate it as the most widely adopted B2B sales intelligence platform
- 270M+ contact database with intent signals is the most comprehensive prospecting database outside enterprise tools like Demandbase
- All-in-one platform eliminates separate subscriptions for a prospecting database, sequencer, dialer, and CRM
- AI email writer generates highly personalized outreach from prospect data without manual research
- Chrome extension works seamlessly on LinkedIn for one-click contact export and enrichment
Cons
- Per-seat pricing on paid plans ($49-99/user/month) adds up quickly for large sales teams vs flat-fee tools like Instantly
- Database accuracy varies — direct dials particularly have lower accuracy than email addresses (requires verification workflow)
- Email deliverability on Apollo's sending infrastructure is lower than dedicated tools like Instantly or Smartlead for high-volume senders
- Free plan limits on mobile numbers (50/month) and export credits frustrate teams needing high volumes at no cost
- Sequencer is less customizable than Smartlead for advanced behavioral branching and multi-domain rotation
- Intent data accuracy and coverage is narrower than enterprise ABM platforms like 6sense or Demandbase
