Apollo.io — All-in-one sales intelligence and engagement platform with a 210M+ contact database, built-in sequences, and a dialer.

Verdict at a glance

Overall rating: 4.0/5 ★★★★☆
Standout: A huge B2B contact database plus outreach sequences and a dialer in one affordable tool.
Watch out: Data accuracy (direct dials and outside the US/UK) trails ZoomInfo, and credit costs climb at scale.

The best all-in-one starter for SMB outbound — database, sequences, and dialer in one place at a fair price. Scrub lists before sending, and expect costs and limits to grow as your motion matures.

Quick facts

• Ideal team: Startups & SMB sales teams
• Learning curve: Low
• Setup time: Minutes
• Support: Email, chat, docs
• Key limit: Credit caps + data-accuracy gaps (direct dials, non-US/UK)
• Top integrations: Salesforce, HubSpot, LinkedIn, Gmail/Outlook

Overview

Apollo.io is a sales intelligence and engagement platform that combines a massive B2B database (210M+ contacts, 30M+ companies) with outreach automation, a built-in dialer, meeting intelligence, and light pipeline tools. You search the database, filter by firmographics, persona, technology, and buying intent, reveal emails and phone numbers, and push prospects straight into sequences — all in one tool.

Its biggest strength is being an affordable all-in-one for SMB outbound; its biggest weakness is data accuracy, with reports of 10–15% outdated emails, weaker direct-dial coverage, and quality that drops outside the US and UK. It is a capable starter that can become expensive and limiting as a GTM motion matures.
