Apollo vs Clay: which fills your sales pipeline
Pick Apollo if you want one app that finds prospects and emails them, with a free plan to start. Pick Clay if you already send from another tool and need sharper lists than any single database gives you. Apollo bundles the contacts, sequences, a dialer and meeting booking, so a founder can run outbound alone in an afternoon. Clay pulls data from many providers into a spreadsheet and lets AI research each company, which pays off for agencies and growth teams but takes real setup time.
Which one to pick
You are a founder or a two-person sales team building your first outbound pipeline and want to find, enrich and email leads from one free account.
You run outbound for several clients or segments and need custom fields, such as a company's tech stack or recent hires, researched for every lead before it reaches your sending tool.

Questions
Is Apollo cheaper than Clay?
Apollo has a free plan that includes contact search and email sequences, so you can start at $0. Clay also has a free plan, and both bill in US dollars. Clay's real cost depends on how many enrichment lookups you run, while Apollo's paid tiers add credits and seats. For a small team sending its own emails, Apollo usually covers more for less.
Can Clay send cold emails on its own?
Clay focuses on building and enriching lists: it does not replace a sequencing tool. You push the finished table into a sender or a CRM such as HubSpot, which Clay connects to natively. Apollo sends sequences itself and adds a dialer and meeting booking. That is the main reason solo founders tend to start with Apollo.
Is Clay hard to learn?
Clay asks more of you than Apollo. You design the columns, choose which providers to query and write the AI research prompts yourself. Teams that invest a week in it get lists no off-the-shelf database matches. If you want results on day one, Apollo's search filters are quicker.
Can I use Apollo and Clay together?
Many outbound teams do. Clay can enrich and score a list, then you load it into Apollo or your CRM to run the sequences. Apollo also connects to HubSpot, Pipedrive and Gmail. Start with Apollo alone and add Clay once your lists, not your sending, become the bottleneck.
Do Apollo and Clay work for prospects in Spain, Germany, France or Italy?
Both are available to teams across Europe, including Spain, Germany, France and Italy. Their data covers European companies, though depth varies by country and sector, so test a sample of your own target accounts. Cold email to European business contacts falls under GDPR and national rules. Keep your outreach targeted and give every recipient a clear way to opt out.
