Apollo vs Clay: Differences, Pricing and How Teams Use Them Together

Apollo and Clay solve different problems, so the real answer is often "both." Apollo is a B2B contact database with built-in sequences and a dialer, the place you find people and work them. Clay is an enrichment and workflow layer that pulls data from many providers (Apollo included), researches accounts with AI and scores leads, then pushes the results wherever you send from.

If you can only pick one and you need pipeline this quarter, pick Apollo. If you already have data and a sending tool but need deeper research and custom qualification, Clay is the stronger addition.

The core difference: database vs workflow layer

Apollo owns its data. You search its database with filters (job title, persona, location, company size, buying intent and more), reveal emails and phone numbers with credits, and act on them inside Apollo. Our Apollo.io review covers the full feature set.

Clay does not depend on one database. It works like a spreadsheet where every column can run an action: look up an email from one provider, try a second provider if the first comes back empty (a "waterfall"), ask an AI agent called Claygent to research a company, or score a row against your rules. Clay describes itself as "infrastructure to get any data, run agentic workflows, and launch GTM plays."

That is why the comparison is not quite apples to apples. Apollo is a destination; Clay is a pipeline.

Why teams use them together

Apollo and Clay have an official integration in both directions, and each vendor frames the split the same way. Apollo's integration page describes Clay as handling "data enrichment, qualification, scoring, and workflow orchestration," with Apollo as an execution channel that is "ideal for teams who need a reliable platform for email sequences and dialing."

In practice, the combined setup looks like this:

The Clay actions that connect to Apollo

Clay's Apollo integration page lists these actions, each marked "Bring Your Own Account Required":

• Enrich Person and Enrich Company to add Apollo data to a row.
• Find People and Find People at Company By Job Title to pull contacts at target accounts.
• Find or Create Contact and Update contact to manage Apollo records.
• Add contact to sequence and Update contact status in sequence to enroll people in Apollo sequences.

One detail matters when you build the flow: the "Add contact to sequence" action requires the contact to already exist in Apollo. So a typical table runs Find or Create Contact first, then adds the contact to the sequence. Apollo enrichment called from Clay also uses your Apollo credits, so watch both balances.

A sample combined workflow

1. In Apollo, build a saved search for your ICP companies and export or sync the account list.
2. In Clay, import the accounts and run Find People at Company By Job Title for your buyer roles.
3. Add a waterfall to fill missing emails from extra providers, then a verification step.
4. Use Claygent to research each account (for example, "Is this company hiring SDRs?") and score rows.
5. Filter to qualified, verified contacts and write a short personalized line with an AI column.
6. Run Find or Create Contact, then Add contact to sequence to push them into an Apollo sequence.
7. Work replies, calls and LinkedIn tasks in Apollo, synced to your CRM.

If you would rather send from a dedicated platform than from Apollo, the same table can push contacts to a tool like Smartlead or Instantly instead. Our Apollo to Smartlead workflow shows that route end to end.

Data and enrichment

Apollo's data

Apollo's data comes from a contributor network, engagement data such as replies and bounces, public web crawling and third-party providers, according to its data overview. It labels every email (Verified, Unverified, Catch-all and others), says its verified emails have a 91% accuracy rate, and refunds the email credit if a verified email bounces within 30 days. Apollo also offers waterfall enrichment inside its own product.

Clay's data

Clay's homepage says you can "buy data from 200+ providers in one place" (Apollo's integration page cites 100+ and 150+ in different spots, so the count depends on how it is measured). The point is coverage: if one provider misses an email, the next one in the waterfall may have it. Clay also tracks signals such as job changes and promotions.

Best for coverage on hard-to-find contacts: Clay. Best for fast, filtered list building: Apollo.

Outreach and execution

Apollo was built to act on data. Sequences support automatic email, manual email, phone call, action item and LinkedIn steps, you pick sending mailboxes when you enroll contacts, and the dialer and meetings live in the same workspace. Apollo's own sending guidance is to start at 50 emails per mailbox per day and stay in the 50 to 100 range.

Clay has a native sequencer, and its pricing page says Launch and higher plans can send emails via Clay or integrations, with Growth adding the option to buy domains and mailboxes for the Clay Sequencer. The page is inconsistent about whether the Free plan includes email sequencing, so check before you plan around it. Apollo's own integration page frames the split the common way: Clay as the data and logic layer, with Apollo (or a dedicated sending tool) doing the sending.

Best for running sequences, calls and LinkedIn tasks: Apollo.

Pricing (as of October 2026)

Apollo

Apollo's pricing page lists Free, Basic, Professional and Custom plans without dollar figures in its page text. Third-party pricing reviews report Basic at about $49, Professional at about $79 and Organization at about $119 (three-seat minimum) per user per month billed annually, with monthly billing costing more. Credits are pooled across the team and do not roll over.

Clay

Clay prices by usage, not seats. Its pricing page (October 2026) shows:

The same page also shows headline figures of $167 and $446 per month on the plan cards and quotes $185 and $495 in its FAQ, so the number you pay depends on the action and credit tiers you choose. Actions reset each cycle; data credits roll over on Launch and Growth up to twice the monthly amount.

What this means for your budget

A solo founder or small sales team usually spends less with Apollo, because one seat covers data and sending. Clay gets more cost-effective as headcount grows (unlimited seats) and as enrichment needs get complex. Running both means paying for both, plus any Apollo credits that Clay's Apollo actions consume.

Ease of use

Apollo has a learning curve, but the path is familiar: filter, save, list, sequence. A new rep can be productive in a day or two, especially with our guide on how to use Apollo for prospecting.

Clay is far more flexible and far less guided. You design tables, chain actions, write AI prompts and debug empty columns. That power is the reason people buy it, and the reason many companies give it to a dedicated GTM engineer rather than every rep.

Strengths and weaknesses

Apollo strengths

• Data, sequences, dialer, meetings and CRM sync in one product.
• Fast list building with detailed filters, saved searches and alerts.
• Clear email statuses and a refund on verified emails that bounce within 30 days.
• Simple per-seat pricing and a free plan.

Apollo weaknesses

• One primary data source, so coverage gaps in some regions and niches.
• Phone numbers cost about 8 credits each, and credits do not roll over.
• Built-in sending is not meant for very high cold email volume.

Clay strengths

• Waterfall enrichment across many providers for better coverage.
• AI research and custom scoring that a filter-based tool cannot match.
• Unlimited seats and integrations with Apollo, CRMs and ad platforms.

Clay weaknesses

• Steep learning curve; tables take real time to build and maintain.
• Usage-based pricing that can climb fast and is confusing on the pricing page itself.
• Not a full outbound workspace for reps on its own.

Three common setups

Setup 1: Apollo only

You search, verify, sequence and call inside Apollo. This is the simplest and cheapest stack, and it fits founders, small sales teams and anyone running moderate volume. The trade-off is that you rely on one data source and Apollo's built-in filters for qualification.

Setup 2: Apollo plus Clay

Apollo stays the system reps work in, and Clay sits upstream. Clay pulls accounts and contacts (often through its Apollo actions), fills gaps with waterfalls, researches and scores each row, then pushes only qualified contacts into Apollo sequences. This setup suits teams with a GTM engineer or ops person and buyers who are hard to find in one database.

Setup 3: Apollo or Clay for data, a dedicated tool for sending

Data and qualification happen in Apollo, Clay or both, and the emails go out through a sending platform with inbox rotation and warmup across many mailboxes. This is the usual shape for high-volume cold email, and it keeps your data subscription separate from your sending infrastructure.

Questions to ask before you buy

• How many contacts do you need each month, and how many are hard to find?
• Who will build and maintain Clay tables, and do they have the time?
• Will you send from Apollo, Clay or a dedicated sending tool?
• What is your real monthly budget across data, credits and sending?

Which should you choose?
