Clay starts at $149/month (Starter) and Apollo starts at $49/user/month (Basic), so Apollo is cheaper for straightforward contact data and email outreach. Clay costs more because it's a data orchestration platform that aggregates 100+ enrichment sources, while Apollo bundles its own B2B database with a built-in sales engagement engine. Your best choice depends on whether you need raw automation flexibility or an all-in-one outreach tool.
Clay and Apollo solve different problems
Most teams compare these two like they're the same product. They aren't. Apollo is a sales intelligence and engagement platform — it owns a database of roughly 275 million contacts, lets you build lead lists, and sends sequences directly from the app. Clay is a spreadsheet-style automation tool that pulls data from dozens of providers (including Apollo as one of its sources), then enriches and routes it into your workflows.
Put simply: Apollo is the destination. Clay is the engine that feeds multiple destinations. If you just want to find prospects and email them, Apollo does that out of the box. If you want to chain together waterfalls of enrichment, AI scoring, and custom signals, Clay is built for that.
Apollo pricing breakdown
Apollo uses per-seat pricing with credit allocations for contact reveals (mobile numbers and verified emails). As of recent pricing:
- Free: $0 — limited credits, basic sequences, good for testing.
- Basic: ~$49/user/month — more credits, A/B testing, advanced filters.
- Professional: ~$79/user/month — adds dialer, plays, and deeper analytics.
- Organization: ~$119/user/month (5-seat minimum) — call transcripts, advanced security.
Apollo's strength is that one subscription covers data, email sending, and a built-in dialer. For a small team running standard sequences, you can run a full outbound motion for under $100 per rep. Check the Apollo pricing page for current credit limits, since they adjust these periodically.
Clay pricing breakdown
Clay charges by plan tier plus credits. Credits get consumed every time you run an enrichment or call an external provider. Recent tiers:
- Free: $0 — 100 credits/month, no credit card.
- Starter: ~$149/month — 2,000 credits, integrations, basic AI.
- Explorer: ~$349/month — 10,000 credits, more features.
- Pro: ~$800/month — 50,000 credits, advanced AI and CRM integrations.
- Enterprise: custom pricing.
The catch with Clay is that credits burn fast when you stack multiple data sources in a single waterfall. Enriching one contact through five providers can cost several credits. Teams that don't plan their credit budget get surprised by overage. See the Clay pricing page for current credit math.
Direct cost comparison
| Factor | Clay | Apollo |
|---|---|---|
| Entry paid plan | ~$149/month | ~$49/user/month |
| Pricing model | Plan tier + credits | Per seat + credits |
| Owns a contact database | No (aggregates 100+ sources) | Yes (~275M contacts) |
| Built-in email sequencing | No (routes to other tools) | Yes |
| Built-in dialer | No | Yes (Pro+) |
| Best for | Custom enrichment, GTM automation | All-in-one outbound |
Which is cheaper for outbound prospecting?
For a typical SDR running standard sequences, Apollo is the cheaper and faster path — one tool, one subscription, send from the app. Clay almost always costs more once you factor in credit consumption plus the downstream tool you'll send through (since Clay doesn't send emails itself).
But the math flips if you value data quality. Clay's waterfall enrichment can produce significantly higher email and phone match rates than any single database, because it falls back across providers until it finds a hit. If your bottleneck is bad data killing your deliverability, paying more for Clay can lower your cost-per-meeting. This matters most when you're trying to automate personalized cold outreach for B2B SaaS at scale, where data accuracy directly affects reply rates.
It's also worth comparing both against fully managed alternatives — sometimes the spend on outsourcing B2B business development lands close to a stacked Clay-plus-sending-tool setup.
A common hybrid setup
Plenty of teams run both. They use Clay for enrichment and AI-driven personalization, then push clean records into Apollo (or a dedicated sending tool) for sequencing. Clay even has an Apollo integration, so you can pull Apollo data into a Clay table without a separate seat. This combo costs more, but you get Clay's flexibility plus a reliable sending engine.
If budget is tight, start by exploring B2B prospecting platforms with generous free tiers before committing — both Clay and Apollo offer free plans you can stress-test.
Key takeaways
Apollo wins on price and simplicity for standard outbound — roughly $49 to $79 per seat covers data and sending. Clay wins on data quality and automation flexibility but starts at $149/month and burns credits quickly, plus you still need a separate sending tool. Pick Apollo if you want one affordable tool that does everything. Pick Clay if data accuracy and custom GTM workflows justify the higher spend. Many high-performing teams run both, using Clay to enrich and Apollo to send.
