Quick answer: Clay and Apollo.io are different kinds of tool. Apollo is a contact database (240M+ contacts, 30M+ companies) with sequences, a dialer and a CRM layer built in, sold per seat from $49 a month billed annually. Clay is an enrichment and workflow builder that buys data from 150+ providers, runs waterfalls and AI research on your lists, and bills by usage from $185 a month (unlimited seats). Pick Apollo if you want one place to find contacts and email them. Pick Clay if you already have lists and need deeper, custom enrichment. Many outbound teams run both. Prices vendor-published, checked September 2026.
“Clay vs Apollo” is a slightly unfair fight, because the two products start from opposite ends. Apollo gives a rep a searchable database and a sending engine on day one. Clay gives a RevOps person or GTM engineer a spreadsheet-like canvas where every column can call a data provider, an AI model or another app. Plenty of teams feed one into the other.
This guide compares them feature by feature, then covers pricing, data coverage and who each fits, and ends with how the two work together. For deeper single-tool coverage, see our Clay review and Apollo.io review.

What Is the Difference Between Clay and Apollo?
The simplest way to see it: Apollo sells you data plus a place to use it. Clay sells you a way to assemble data from many sources and move it where it needs to go.
In Apollo, a rep filters the database by title, industry, headcount or intent topic, reveals emails and phone numbers with credits, and drops the contacts into a sequence. The whole loop happens inside one app, and each seat gets its own inbox connections, tasks and dialer.
In Clay, you start with a table of companies or people. That list might come from a CSV, your CRM, a Clay search, a LinkedIn export or Apollo itself. You then add columns: find the work email through a waterfall of providers, pull a mobile number, ask Claygent to read the company’s careers page, score the account against your ICP, write a first line, and push the row to your CRM or sequencer. Clay describes its two meters plainly: Data Credits pay for the data, Actions pay for the work Clay does.
So the honest answer to “is Clay better than Apollo” is that they win on different jobs. Clay wins when the data you need is unusual (a tech stack, a hiring signal, something only visible on a website) or when one provider’s coverage is too thin. Apollo wins when speed, simplicity and a built-in sending tool matter more than squeezing out the last 10% of coverage.
How Waterfall Enrichment Differs in Clay and Apollo
Both tools now run waterfalls, which is where the comparison gets closer than it used to be.
- Clay: its guide defines a waterfall as a fallback chain where “you stop at the first confident result”. You choose and reorder the providers, and Clay’s product page names Prospeo, DropContact, Datagma, Hunter, People Data Labs, Apollo, Lusha and Snov among the email sources. If an enrichment returns nothing, Clay charges neither Actions nor Data Credits.
- Apollo: waterfall enrichment launched at ApolloNEXT in October 2025 and became the default for paid plans in December 2025. Apollo is always the first source and cannot be moved. Apollo’s help center notes that its run “continues until a validated result is found or every source has been tried” and that an optional validator charges separately, so more than one source can bill on a single record. Apollo’s API docs put a typical email waterfall at 1 to 4 credits and a phone waterfall at 8 to 25.
In practice, Apollo’s waterfall is a convenience layer on top of its own data. Clay’s is the product itself, with far more control over order, providers and cost.
Clay vs Apollo Pricing
The two price in completely different ways, which is why like-for-like comparisons online are often wrong.
Apollo.io pricing
| Plan | Billed annually (per seat/mo) | Billed monthly | Credits |
|---|---|---|---|
| Free | $0 | $0 | 900 per seat per year, granted monthly |
| Basic | $49 | $65 | 30,000 per seat per year upfront (2,500 a month on monthly billing) |
| Professional | $79 | $99 | 48,000 per seat per year (4,000 a month) |
| Organization | $119, minimum 3 seats | Annual only | 72,000 per seat per year |
An email costs 1 credit and a phone number 8. Add-on packs run from 400 credits for $10 to 5,000 for $100 a month. Vendor-published, checked September 2026. Full breakdown in our Apollo.io pricing guide.
Clay pricing
| Plan | Billed monthly | Billed annually (per mo) | Actions / Data Credits a month |
|---|---|---|---|
| Free | $0 | $0 | 500 / 100 |
| Launch | From $185 | From $167 | 15,000 / 2,500 |
| Growth | From $495 | From $446 | 40,000 / 6,000 |
| Enterprise | Custom | Custom, annual commitment | 100,000+ / 200,000+ Actions |
Data Credits start at $0.05 each and Actions at under $0.01. Seats are unlimited on every plan. Vendor-published, checked September 2026. See our Clay pricing guide for the slider tiers.
What 1,000 contacts a month costs on each
Using only the published rates above, for one user on monthly billing:
| Scenario | Apollo.io | Clay |
|---|---|---|
| 1,000 work emails | 1,000 credits. Fits in Basic’s 2,500 a month: $65 | Clay’s own example (0.5 credit for the profile plus 0.5 for the email) fits Launch’s base allowance: $185 |
| 1,000 emails and 1,000 phone numbers | 9,000 credits. Professional (4,000) plus a 5,000-credit pack ($100): about $199 | At Clay’s “6 to 20 Data Credits per fully enriched record”, 6,000 to 20,000 credits: $350 to $940 |
| Five users doing the above | Five seats, so roughly five times the cost | Same price; seats are unlimited |
Two caveats. Phone hit rates are never 100%, and both vendors say they only charge when data is found, so real bills usually land lower. And Clay’s figure buys data from several providers with custom research on top, which Apollo’s price does not include. For a single rep, Apollo is cheaper. For a team where one operator enriches lists that five reps use, Clay’s unlimited seats close the gap.
Data Coverage: Who Has Better Data?
Apollo’s coverage is its own: “240M+ contacts and 30M+ companies” on its site, with emails verified through a seven-step process and phone numbers verified when you request them (Apollo’s claims). Its data is partly contributed by a network of users who connect inboxes and CRMs. Coverage is strongest for North American tech and SMB contacts; Apollo publishes no regional breakdown.
Clay has no single database, so its coverage is whatever its 150+ partners hold, stacked in the order you choose. That is the main argument for Clay: one provider rarely finds every email, and waterfalling several raises the hit rate. Clay’s own product page says waterfalls “routinely triple” coverage for its customers. That is a vendor claim, not an independent test, but the logic holds for niche markets and regions where any single database is thin.
Public sentiment on Apollo’s data is mixed. On Trustpilot, Apollo is rated 3.1 out of 5 across 1,333 reviews, with complaints about support delays and some wrong phone numbers alongside praise for the feature set (checked September 2026). Clay’s quality depends on the providers you connect, so there is no single accuracy figure to quote.
Is Clay an Outbound Tool Like Apollo?
Partly. Clay now includes the Clay Sequencer for email on every plan, and Growth lets you buy domains and mailboxes for it. But most Clay users still push enriched rows into a dedicated sending tool such as Instantly, Smartlead or lemlist, or into Outreach or Salesloft. Clay has no dialer, no task queue for reps and no meetings or deal pipeline.
Apollo is the opposite: sequences, a dialer with call recordings and AI insights (Professional), deal management and meeting booking are part of the seat. If your reps need one tab to live in, Apollo is that tab. For the sending side, see our cold email software comparison.
Can You Use Clay and Apollo Together?
Yes, and it is one of the most common stacks in outbound. Three patterns come up again and again:
- Apollo as the list source, Clay as the enrichment layer. Export or sync accounts and people from Apollo’s search, then use Clay to find what Apollo missed (mobiles, personal emails for founders, tech stack, hiring signals) and to write personalised lines. Send the finished rows back to Apollo sequences.
- Apollo as one provider inside a Clay waterfall. Apollo is named on Clay’s waterfall page as an email source. If you already pay for Apollo, connecting your own API key means Clay only charges Actions for those lookups.
- Clay for the operator, Apollo for the reps. One GTM engineer builds and maintains enrichment tables in Clay; reps prospect, call and sequence in Apollo seats. This keeps Clay’s learning curve in one person’s hands.
The trade-off is paying two bills. If your team has fewer than three reps and no one who enjoys building workflows, starting with Apollo alone is usually the better call.
Who Should Choose Clay
- RevOps teams and GTM engineers who want full control over data sources and cost per field.
- Teams selling into niches or regions where one database misses too many contacts.
- Companies that need custom signals: job posts, website changes, funding news, technology used.
- Larger teams where unlimited seats beat per-seat pricing.
- Anyone enriching CRM records at scale (Growth plan and up).
Who Should Choose Apollo
- Founders, solo sellers and small SDR teams who need contacts and sequences in one place.
- Teams that want a free plan to test data quality in their market before paying.
- Reps who call as well as email, since the dialer is built in.
- Buyers who want predictable per-seat pricing over usage meters.
If you are weighing Apollo against enterprise data, our Apollo vs ZoomInfo comparison covers that decision. If neither tool fits, see the lists of Clay alternatives and Apollo.io alternatives.
How to Choose Between Clay and Apollo
- Start with who will use it. Reps who prospect daily lean Apollo. An operator who builds lists for others leans Clay.
- Test coverage on your own market. Take 100 real target contacts. Run them through Apollo’s free plan and Clay’s free plan and count verified emails and mobiles found.
- Price your real volume. Work out emails and phones per month, then use the tables above. Phones drive cost on both.
- Check where emails will be sent. If you already use a sequencer, Clay slots in front of it. If you have nothing, Apollo covers sending out of the box.
- Consider both. Many teams end up with Apollo for reps and Clay for enrichment once volume grows.

Frequently Asked Questions
Is Clay better than Apollo?
Not across the board. Clay is better for custom, multi-source enrichment and workflow automation. Apollo is better for finding contacts and emailing or calling them from one tool. The right choice depends on whether your bottleneck is data depth or rep speed.
Does Clay use Apollo data?
It can. Apollo is listed as one of the email providers in Clay’s waterfall. You can also connect your own Apollo API key in Clay, in which case Clay charges Actions but no Data Credits for those lookups.
Which is cheaper, Clay or Apollo?
For one user, Apollo. Basic is $49 per seat a month billed annually and covers 1,000 emails a month. Clay starts at $185 a month. Clay becomes competitive for larger teams because its seats are unlimited, while Apollo charges per seat.
Can Clay send emails?
Yes. The Clay Sequencer is included on every plan, and Growth adds in-app domain and mailbox purchase. Most teams still pair Clay with a dedicated cold email tool for deliverability features like warmup and inbox rotation.
Does Apollo have waterfall enrichment like Clay?
Yes, since late 2025. Apollo checks its own data first, then 20+ partners in an order you set. Clay offers more providers (150+) and more control, and stops at the first confident match.
Is Clay hard to learn?
Harder than Apollo. Clay is a blank canvas of tables, columns and integrations, so expect a few days to build your first reliable workflow. Clay offers templates and a free plan capped at 200 rows per table to practise on.
Should a startup use Clay or Apollo first?
Most early-stage teams start with Apollo because it gives them contacts and sending on a free or $49 plan. Clay makes sense once someone owns list quality full time or the market is too niche for one database.
