B2B sales intelligence platform with a 275 million contact database, email sequencing, built-in dialer, and AI-powered prospecting. The most popular starting point for outbound sales teams.
An AI sales platform that finds leads, writes personalized emails, and manages outreach campaigns — your automated sales team.
Apollo.io packs prospecting, email sequences, a phone dialer, and CRM sync into one platform at a price point that undercuts ZoomInfo by 80% or more. That all-in-one value is why 90% of SMBs start their outbound sales stack here.
The database holds 275 million contacts and 70 million companies. You search by job title, company size, industry, location, tech stack, and dozens of other filters. When you find prospects, you add them to automated email sequences, call them with the built-in dialer (with local presence numbers), and track engagement. No switching between separate tools for each step.
Apollo added an AI SDR assistant that drafts personalized outreach sequences based on prospect data. The AI lead scoring system trains on your conversion data to prioritize prospects most likely to close. Conversation intelligence records and transcribes calls, then creates follow-up tasks based on discussion content. These features ship on the Professional plan ($79/month) and above.
| Plan | Price | Key Features |
|------|-------|--------------|
| Starter | Free | 50 credits/mo, 5 mobile credits, basic prospecting |
| Basic | $49/mo per user | Unlimited email campaigns, phone dialer, CRM integrations |
| Professional | $79/mo per user | AI features, A/B testing, call recording, intent data |
| Organization | $119/mo per user | Team collaboration, advanced admin, custom integrations |
| Custom | Contact sales | Unlimited usage, dedicated infrastructure, SSO |
Replacing Apollo with separate tools: a data provider (Hunter.io at $49/month for 500 searches), an email sequencer ($50-100/month), a dialer ($30-50/month per seat), and a basic CRM. Total: $130-200/month per user. Apollo's Basic plan at $49/month per user covers all of this. The savings are clear for teams consolidating their sales stack.
The hidden cost is credits. Apollo's free plan gives 50 credits per month; each contact lookup or email verification uses credits. Heavy prospectors burn through credits fast and need paid plans.
Reddit users in r/sales call Apollo "the best" for price-to-feature ratio. The r/LeadGeneration community agrees it is "usually the cheapest data provider" and most teams view the data as "good enough." LaGrowthMachine's review highlights the all-in-one approach as Apollo's biggest selling point for startups and mid-market teams.
The complaints are consistent: data accuracy is not best-in-class. One review noted that having 275 million contacts "doesn't matter if 20% of them have bounced." Users report email deliverability issues when sending high-volume sequences without proper warmup. Several Reddit threads describe being "forced into using Apollo because I couldn't get budget" for pricier alternatives, not because it was the preferred choice. The "master of none" criticism surfaces in nearly every in-depth review.
Expect roughly 65% accuracy on email addresses based on independent testing. Verify emails before sending campaigns to protect your sender reputation. Apollo includes basic email verification, but dedicated verification tools catch more bounces.
Yes. Apollo integrates with Salesforce and HubSpot with bi-directional sync. The Organization plan adds deeper sync options and custom integrations.
Apollo does not impose a daily send limit, but email providers do. Gmail caps at 500/day for personal accounts and 2,000/day for Google Workspace. Start with low volumes and warm up gradually.
You can purchase additional credits or upgrade your plan. Credits reset monthly. The Basic plan includes more credits than the free tier but exact allocations vary by contract.

We believe in transparent reviews. Here's what Apollo.io doesn't handle well:
Apollo maintains around 85-90% email accuracy through a combination of machine learning verification and user feedback. Their data is particularly strong for North American companies and technology sectors, but coverage can be inconsistent for international markets or traditional industries. Apollo uses real-time verification and crowd-sourced updates to maintain accuracy, plus they offer credits back for bounced emails, which helps offset data quality issues.
Apollo provides built-in deliverability tools including spam testing, domain health monitoring, and sending reputation management. However, successful deliverability requires proper setup including SPF/DKIM/DMARC records, gradual sending volume increases, and maintaining good sender reputation through engagement tracking. Most successful teams limit daily sends to 50-100 emails per sending domain and use multiple domains for higher volume campaigns.
Apollo offers tiered pricing from $39/month for basic plans up to $79/month for professional features, with enterprise pricing for larger teams. Key limitations include monthly email sends (1,000-5,000 depending on plan), contact exports (500-10,000), and dialer minutes (100-2,000). Teams that need higher volumes typically need custom enterprise plans or multiple user licenses.
Yes, Apollo's account-based features include shared prospect pools, account-level tracking, and coordinated multi-person outreach sequences. You can assign multiple team members to work the same account without overlap, track all touches across the buying committee, and coordinate timing of outreach across different stakeholders. The platform also includes account scoring and prioritization based on engagement across multiple contacts.
Apollo offers native integrations with Salesforce, HubSpot, Pipedrive, and other major CRMs with bi-directional sync capabilities. The Salesforce integration is particularly robust, syncing activities, contacts, and opportunities in real-time. They also offer integrations with Slack, Zapier, and various sales engagement tools. Custom integrations are available through their API for enterprise customers with specific workflow requirements.
