Apollo.io vs Clay:
Which for B2B data and outbound?

Apollo and Clay show up in the same searches, but they do different jobs.

Apollo is a sales platform. You filter its own contact and company database into a target list, enrich the contacts and reach them through email sequences in the same tool. For a rep the flow is simple: filter, save, add to a sequence. Apollo positions itself the same way: one platform to find leads, manage pipeline and close deals.

Clay is a data and workflow platform. You open a table; each row is a company or a person and each column a step: find an email with one provider, ask a second if the first comes back empty (a waterfall), research the company's website with AI, score the result and send the qualifying records to the CRM or a sequencing tool. Clay's pricing page highlights enrichment from 150+ data providers and Claygent, an AI agent that researches the web. Clay is not a sequencing tool or a CRM on its own; it is the layer that connects them.

That is why the real question is often not "Apollo or Clay" but "do we need Clay at all?". Apollo is already one of the data sources Clay can use.

Apollo is priced per user. As of October 2026, on annual billing Basic costs USD 49 per user per month, Professional USD 79 and Organization USD 119 (minimum three users); on monthly billing Basic is USD 65 and Professional USD 99. On annual plans, credits are granted upfront per user per year: 30,000 on Basic, 48,000 on Professional and 72,000 on Organization. The free plan includes 900 credits per user per year. Apollo says credits are pooled across the team and do not roll over at the end of the cycle.

Clay is priced per account and uses two separate meters. Actions measure the work Clay does (running enrichments, calling AI models, exporting); data credits pay for third-party data bought from Clay's marketplace. Launch starts at USD 167 a month on annual billing and USD 185 on monthly billing; Growth at USD 446 and USD 495. Users and tables are unlimited on every plan. When you bring your own API key, you spend no data credits for that provider, but you still spend actions.

In practice, Apollo's cost grows with the size of the sales team, and Clay's with data volume and workflow complexity. A five-rep team reaching a few hundred accounts a month may find Apollo's per-user price more predictable. An operation that enriches and scores thousands of records from several sources can justify Clay's flexibility. Either way, watch credit use closely in the first month.

B2B data quality varies by country, industry and company size. As of October 2026, neither Apollo nor Clay publishes a coverage or accuracy figure for Türkiye. Our advice is simple: take a sample of 100–200 companies from your own target list, run it through both tools, verify the emails and phone numbers found and compare.

That is exactly the logic of Clay's waterfall: where one provider comes back empty, a second and third are tried. Apollo also offers waterfall enrichment on Basic and above. The difference is that in Clay you design which providers run in which order and how the result is handled. For the concept, see the data enrichment entry in our glossary.

Apollo syncs with the CRM and offers automated CRM enrichment and CRM integrations from the Basic plan. Contacts that reps find in Apollo land in the CRM, and sequence activity is written back.

In Clay, CRM auto-sync, data warehouse connections, HTTP API integrations and webhook signals come with the Growth plan. Launch includes signals such as job changes and company news, scheduled runs and email sending, but no CRM integration. If you are building a continuous flow that feeds the CRM, budget for Growth.

The real work in a Clay setup is designing which signal triggers which action, which record is scored on which criteria and where the result is written. That role is increasingly called GTM engineering.

Apollo offers deliverability tools and email warm-up; Clay sends email through its own sequencer or integrations. No tool on its own keeps you out of the spam folder. A separate sending domain, SPF, DKIM and DMARC records, gradual warm-up, a verified list and a sensible sending volume are prerequisites for either setup. If you are comparing Apollo with a sequencing tool, our Apollo vs Lemlist comparison covers this in detail.

Apollo is based in the US; its privacy policy says data may be processed in the US and in other countries where its providers operate, and it sets out GDPR rights and how people can opt out of the Apollo database. Clay says it is SOC 2 Type II compliant and offers a custom DPA on Enterprise; its pricing page does not state a data region.

With both tools, personal data is processed outside Türkiye, and companies here face two separate questions. The first is cross-border transfer: since the 2024 amendment to Article 9 of KVKK, standard contracts are one of the safeguards, and a signed standard contract must be notified to the Authority within five business days. The second is cold email: commercial electronic message rules and the recipient's right to object need their own review. Settle both with your legal counsel; in the setup we keep lists, source records and opt-out requests traceable in the CRM.

In Apollo the first steps are clear: save filters that match your ideal customer profile, connect the CRM, prepare sending domains and mailboxes, and start the first sequences at low volume. In the first weeks, watch bounces alongside open and reply rates.

In Clay the first month is mostly design work: which source supplies which field, the order of providers in the waterfall, which question each AI step answers and the scoring rules. Test on a small table, measure credit use, then scale. That order is the most reliable way to avoid surprise credit spend.

Choose Apollo if your reps will pull lists from a ready database and send sequences from the same tool, you want a predictable per-user cost and you do not yet need custom data workflows.

Choose Clay if you need to combine several data sources, research companies with AI, apply your own scoring rules and write the result to the CRM automatically, and you have a GTM engineer or team to build it.

Use both if you want Apollo as the reps' daily tool and Clay as the background layer that enriches and prioritises the data. Plan the credit budget for both tools together. Without a clear ideal customer profile (ICP), neither tool performs well.
