Apollo

This is best used for B2B sales prospecting and multi-channel outreach with integrated database of 275M+ contacts. Apollo eliminates the need for separate data provider plus sequencing tool—find prospects, verify emails, and launch sequences from one platform.

Key tactical use cases: Building targeted prospect lists with 65+ filters (job title, industry, tech stack, buyer intent), multi-channel sales sequences (email, LinkedIn, calls), data enrichment and CRM hygiene with waterfall verification, Chrome extension prospecting from LinkedIn/company websites, and intent-based outreach triggered by buying signals.

Pricing reality: Free tier includes 10,000 email credits/month with basic sequences. Basic at $49/user/month adds more credits and integrations. Professional at $99/user/month unlocks buying intent and advanced reports. Organization at $149/user/month provides call recording and advanced security.

Data accuracy reality: User reports suggest approximately 65% accuracy—common complaint is burning credits unlocking direct mobile numbers for prospects who left 2 years ago. Best practice: "Don't rely on one data source—stack them" (Apollo + Clay + FullEnrich).

Integration strength: Salesforce, HubSpot, Pipedrive, LinkedIn Sales Navigator, Outreach, Salesloft, Zapier, Gong. Apollo mirrors HubSpot duplicates—dedupe HubSpot first before enabling sync.
