How to Use Clay: A Practical Guide to Lead Generation

January 15, 2026

I'd been paying for three separate data tools before I tried consolidating everything into one platform. The first table I built took maybe 20 minutes to get right, and I pulled around 340 contacts before I felt confident enough to run enrichment on a full list. It's not magic, but it does replace a lot of the copy-paste work I was doing between tools. This guide covers what actually worked, what didn't, and how I set things up for outreach.

What Clay Actually Does

Clay combines a spreadsheet interface with access to 150+ data providers. Instead of subscribing to Apollo, ZoomInfo, Clearbit, and others separately, you access all of them through Clay's "waterfall" enrichment system.

The core idea: you feed Clay a list of companies or people, it automatically searches across multiple data sources to find emails, phone numbers, job titles, and other information, and stops once it finds what you need. You only pay for successful finds.

This matters because no single data provider has 100% coverage. One tool might have contact info for 30% of your targets, another might have 25%. Clay checks them all and uses whichever one has the data, dramatically improving your match rates. OpenAI reported doubling their enrichment coverage from 40% to 80% after switching to Clay's waterfall approach.

Beyond simple contact finding, Clay operates as a complete GTM (Go-To-Market) automation platform. Think of it as a programmable data engine that connects your lead sources, enriches them in real-time, and plugs seamlessly into your outreach workflows. The platform is designed around a framework called FETE: Find, Enrich, Transform, Export.

Setting Up Your Clay Account

Start by signing up at Clay. The free plan includes 100 credits per month (1,200 credits per year) to test things out.

Once you're in, you'll see a workspace with tables. Clay works like a supercharged Google Sheets where each column can run automations.

Pricing scales based on credits consumed. Here's the current breakdown:

The cost per credit decreases significantly at higher tiers. On the Starter plan, you pay around $75 per 1,000 credits. On the Pro plan, that drops to approximately $16 per 1,000 credits-up to 7x cheaper than the Starter tier. This makes scaling more affordable as your lead volume grows.

All plans support unlimited users, which is a significant advantage over per-seat pricing models. Unused credits roll over for one month, adding flexibility to your budget.

Understanding Clay Credits

Clay credits are the currency you use to pay for data enrichment and actions. Understanding how they work helps you avoid burning through your budget unnecessarily.

Most actions cost 1-2 credits, but costs vary by data type and provider:

You only pay when data is successfully found. If Clay can't find the information in its waterfall process, you won't be charged credits. However, if a provider charges Clay for an API call even without returning data, those charges pass through to you-though most providers refund failed lookups.

Actions that clean or format data are free. External CRM connections and email tools are also free on Pro plans and above. Clay only charges for data points where they pay underlying providers.

Track your credit usage by right-clicking any column and selecting "Run Info" to see credits spent on that column. Plan your workflows on small test batches before running them at scale to avoid credit waste from poorly configured automations.

Building Your First Lead List

Create a new table and decide your starting point. You can import from:

Most people start with Clay's built-in search. Click "Add Rows" and select "Find Companies" to search by criteria like industry, employee count, location, technology used, and funding status.

For example, to find SaaS companies in the US with 50-200 employees, you'd set those filters and Clay pulls from its database. This costs about 1 credit per company found.

For people search, use "Find People at Company" if you already have a company list, or "Find People" to search by job title and location. Finding a VP of Sales at tech companies in California would use filters for title, industry, and geography.

The free plan caps searches at 100 results per individual people/company search. Starter plans increase this to 5,000 results, Explorer to 10,000, Pro to 25,000, and Enterprise to 50,000 results per search. This scaling matters when you're building large prospecting campaigns.

Setting Up Enrichment Waterfalls

This is where Clay gets powerful. Instead of manually searching for each person's email across different tools, you build a waterfall that automates it.

The waterfall method works by searching sequentially across multiple data providers until a valid match is found. Here's the process:

  1. You select from 150+ enrichment tools in Clay's marketplace
  2. The system checks each provider in sequence until it finds the data you need
  3. Once a provider returns valid data, Clay stops and charges only for that successful find
  4. If no data is found, credits are refunded and Clay moves to the next provider

Add a new column and select "Enrich Person" or "Enrich Company." Clay shows you 150+ available data sources. Select multiple providers in priority order.

For example, to find work emails, you might choose:

  1. Prospeo (2 credits per find)
  2. DropContact (2 credits)
  3. Hunter (2 credits)
  4. Apollo (1 credit)

Clay tries Prospeo first. If it finds the email, it stops and charges 2 credits. If not, it tries DropContact, then Hunter, then Apollo. You only pay for the provider that successfully returns data.

This dramatically improves match rates. A single provider might find emails for 40% of your list. A 4-provider waterfall can hit 70-80%. Teams using Clay's waterfall enrichment routinely triple their enrichment rates compared to single-provider solutions.

Set this up for phone numbers, LinkedIn URLs, job titles, company revenue, or any other data point you need. Each enrichment type gets its own waterfall column.

Email Validation in Waterfalls

Clay's email waterfall doesn't just find emails-it validates them automatically. By default, Clay uses ZeroBounce, a best-in-class validation service, but you have flexibility to choose different providers if you know one validates better for your specific industry.

Clay considers catch-all emails valid by default. While these are often real emails, there's uncertainty about whether they belong to the specific individual or if they're aliases. If you want to be more conservative, enable the "Only mark 'Safe to Send' emails as valid" option to exclude catch-all emails from your valid list.

Validation columns are hidden by default, but you can unhide them from the Columns Panel to inspect detailed validation steps and understand exactly how each email was validated.

Using AI to Personalize Outreach

Clay includes powerful AI integration for writing personalized messages at scale. After enriching your leads, add a "Use AI" column or leverage Claygent, Clay's built-in AI research agent.

Claygent can scrape websites, read PDFs, summarize news, find podcast appearances, analyze company 10-Ks, check Yelp ratings, discover recent blog posts, and answer arbitrary questions about accounts or people. It's essentially an AI research assistant that gathers contextual insights traditional data providers can't capture.

Write a prompt like: "Write a 2-sentence personalized opener for an email to {{job_title}} at {{company_name}} mentioning their recent {{news_item}}. Keep it casual and relevant."

Clay's AI reads the data from your other columns and generates unique text for each row. This costs credits based on AI usage, roughly 0.1-0.5 credits per generation depending on prompt complexity and the AI model selected.

The platform now supports GPT-5 and Claude 3.5 Sonnet, giving you access to the latest AI models. Claude 3 Haiku became a top choice among Clay customers for cost-effective personalization, while GPT-5 delivers the best research and conversational writing for more sophisticated use cases.

The quality depends entirely on your prompt and available data. Generic prompts produce generic output. Specific instructions with rich data inputs (recent funding, job changes, tech stack, hiring signals) produce better personalization.

Test your prompts on 10-20 rows before running them on thousands. Bad AI copy at scale wastes credits and hurts response rates. Use the "Test Run" function to preview AI output before running it across hundreds of rows.

Advanced Claygent Use Cases

Claygent goes beyond simple email personalization. Here are advanced ways to leverage Clay's AI agent:

Competitive intelligence: Use Claygent to monitor what filters and keywords competitors show up for. If your company isn't appearing even with enrichments, you've got positioning work to do. You can also track if competitors are moving into certain verticals or running plays you're not seeing.

Signal detection: Set up Claygent to monitor job postings, keyword mentions, funding announcements, and other intent signals. When these triggers fire, automatically enrich the account and launch personalized outreach.

Account research: Provide Claygent with a list of companies or domains, and it will scour the web to find case studies, technology stacks, SOC-II compliance status, recent product launches, and more. The AI continuously learns and improves its research capabilities.

Finding local businesses: Most data vendors struggle with local businesses. Clay users have created workflows that scrape 50,000+ restaurant names and 30,000+ contacts by location overnight using Claygent combined with Google Maps integration.

Custom scoring: Use Claygent to build lead scoring based on multiple data points-company growth signals, hiring trends, tech stack alignment, content engagement, and recent company news. This helps prioritize outreach to high-intent accounts.

Filtering and Cleaning Your Data

After enrichment, you'll have incomplete rows where Clay couldn't find certain data points. Use filters to segment your list.

Click the filter icon and set conditions like "Email is not empty" and "Email verification status = valid." This shows only rows with verified emails.

You can also filter by company size, location, or any enriched data point. Save these as views to quickly switch between different segments.

Clay's filtering approach prevents wasting credits on bad data. Inside Clay, add filters to remove contacts who don't meet your criteria-companies that are too small, contacts in the wrong region, or people already in your CRM. You can set up lookup tables to catch duplicates, block known customers, or flag bad domains.

This matters because 25-30% of B2B data becomes outdated every year. Enriching blindly risks bad outreach, wasted credits, and a messy CRM. Clay helps you filter the junk first so your enrichment budget goes further.

A lot of other tools enrich the second you upload a list. With Clay, you choose exactly which contacts get enriched and when it happens. If someone doesn't match your criteria, they don't get enriched-saving both time and money.

Delete or hide rows where critical information is missing. Don't export contacts without verified emails to your outreach tool-it tanks deliverability.

Exporting to Your Outreach Tools

Clay integrates directly with cold email platforms and CRMs. Connect your tools under the Integrations tab.

Popular integrations include Smartlead, Instantly, HubSpot, Salesforce, Pipedrive, Outreach, Salesloft, Apollo, and Lemlist.

For email outreach, map your Clay columns to fields in your outreach tool: First Name, Last Name, Email, Company, Custom Variable 1 (your AI-generated opener), etc.

Set up the integration to push leads automatically when new rows are added and pass your filters. This creates a continuous pipeline from prospecting to outreach.

If your tool isn't integrated, export as CSV and upload manually. Select your filtered view, click Export, and choose which columns to include.

CRM Integrations for Attribution

Clay's CRM integrations go beyond simple data sync. When connecting with HubSpot, for example, you can build a closed-loop system that tracks performance from first touch to closed-won.

Start by pulling filtered contact records from HubSpot using real HubSpot IDs. Clay's waterfall enrichment runs on these contacts, then updates are pushed back using ID-matching with "ignore blank values" to protect clean fields.

Tag every record with a campaign name in Clay so you can track performance in HubSpot Campaign Reports later. Associate enriched contacts to deals, then use HubSpot's reporting to connect campaigns to real revenue.

This approach saves sales teams an average of 4 hours per rep each week by avoiding manual exports and keeping CRM records synced automatically.

Building Advanced Workflows

Once you're comfortable with basic enrichment, Clay supports complex multi-step workflows.

Example: Find companies using Salesforce with 100-500 employees, enrich with recent funding data, find VPs of Sales at those companies, verify their emails, check if they're actively hiring, generate personalized openers mentioning their growth, and push to Smartlead only if all conditions are met.

This uses conditional logic, multiple enrichment steps, and filtering. Each step is a column, and you chain them together.

Clay's formula system (similar to Excel) lets you combine data, format text, or calculate values. Use it to build full names from first/last, create custom tracking parameters, or score leads based on multiple criteria.

The HTTP API column lets you connect to any external service. Pull data from your own database, trigger webhooks, or integrate tools that don't have native Clay connections.

Trigger-Based Workflows

Clay enables real-time automation based on intent signals and buying triggers:

Job change tracking: Auto-enrich contacts from LinkedIn when saved searches detect job changes at target accounts. Launch personalized outreach the moment someone moves to a new role.

Funding triggers: Monitor external signals like funding announcements from Crunchbase or news APIs. When a trigger fires, Clay finds decision-makers at newly funded companies, enriches profiles, and initiates email sequences.

Hiring signals: Track job postings and keyword mentions to detect intent. Route hot leads to Slack for immediate SDR follow-up when companies are actively hiring for roles that signal buying intent.

Website visitors: Integrate with visitor identification tools to enrich website traffic data. Create messages that address the exact pages they visited, resources they downloaded, and topics they showed interest in.

By aggregating data on hiring trends, funding rounds, LinkedIn activity, and keyword mentions across 130+ real-time sources, Clay empowers GTM teams to detect high-intent accounts automatically and engage at exactly the right moment.

Avoiding Common Clay Mistakes

The first thing I got wrong was running enrichment on a list I hadn't cleaned. Burned through a few hundred credits before I realized half the companies I'd imported didn't have accurate data to pull from. Now I verify the company list first, then go looking for people. Sounds obvious in hindsight.

Waterfall setups matter more than I expected. I started with a single provider and was getting maybe 40% coverage on emails. Once I stacked three providers in sequence, that number climbed noticeably. The logic is simple once you've built it once -- each provider tries if the one before it comes back empty.

Email verification isn't optional. I skipped it early on and sent to a batch of addresses that came back from enrichment unverified. Bounce rate hit around 19%. After I added a verification step into the waterfall, it dropped to under 5%. That was a bad week I won't repeat.

I kept overbuilding workflows at first. Spent a lot of time adding logic I didn't need yet. The simpler version -- company lookup, person lookup, email waterfall -- handled most of what we actually needed. I add steps now only when something specific breaks or goes missing.

AI prompts need more specificity than feels natural. My first few attempts were vague and the output was unusable. When I started including the exact field references and what I wanted the sentence to accomplish, the copy got a lot more workable. It still needs editing, but it's a real starting point now.

Test on small batches first. I duplicate the table, run maybe 15 rows, check the results, then decide if it's ready to scale. Caught a looping issue that would have cost a lot of credits before it ran on the full list.

Watch your credit usage actively. It doesn't pace itself for you. I underestimated a campaign once and ran dry mid-run. Now I use the credit estimator before anything larger goes out.

Clay vs Building Your Own Stack

Before I found this tool, I was paying for Apollo, Hunter, and manually cross-referencing everything for leads that still came back half-empty. The per-tool subscriptions add up fast, and you're still doing cleanup work on the back end.

The credit system here is different. You pay when it actually finds something, spread across all the providers it queries. When we were enriching around 6,400 leads in a month, the cost came out to roughly $410. Running that same list through separate subscriptions would have been closer to $2,200. That math was pretty clear.

That said, there is a learning curve. I won't pretend otherwise. For smaller lists, something like Findymail or Apollo is honestly less friction. If you're under 500 leads a month, the setup time probably isn't worth it.

Compared to Apollo specifically, the biggest difference is that Apollo keeps everything in one place. Sequences, calling, tracking. Tory uses Apollo and likes not having to think about it. This tool doesn't do outreach execution, so you're wiring in a separate sender. That's a real extra step. But where Apollo gave us coverage gaps on anything outside North American SMBs, this one held up better. The waterfall approach means it's querying multiple sources in sequence, so if one misses, another picks it up.

Against ZoomInfo, the comparison is more about freshness. ZoomInfo's database is large but it's a snapshot. When we were prospecting into sectors with high turnover, the role data was often stale. Here, it's pulling in real time, which matters when someone's title changed three months ago and ZoomInfo still has the old one. On G2, company data accuracy scores about a full point higher here than it does for ZoomInfo. That tracks with what I actually saw in the results.

ZoomInfo makes sense if you're enterprise-scale and need volume above everything else. For most mid-market prospecting work, the flexibility here is worth more than the database size.

Clay Integration Ecosystem

Clay connects with 150+ data providers and business tools, making it a central hub for GTM operations:

Data providers: Apollo, ZoomInfo, Clearbit, People Data Labs, Hunter, Prospeo, DropContact, Datagma, Lusha, Snov, RocketReach, ContactOut, and 100+ more

CRMs: HubSpot, Salesforce, Pipedrive, Zoho CRM, Microsoft Dynamics 365

Email sequencers: Smartlead, Instantly, Lemlist, Outreach, Salesloft, Mailshake

Productivity tools: Slack, Notion, Google Sheets, Airtable, Zapier, Make

Intent data: Gong, Semrush, PitchBook, HG Insights, Mixrank

Social platforms: LinkedIn Sales Navigator, Twitter/X, Modash

Verification tools: ZeroBounce, NeverBounce, Findymail

Each integration has different credit costs. For example, using your own API keys (OpenAI for AI, your own data provider subscriptions) means you can use those actions in Clay free of charge. Clay's native integrations typically cost 0-2 credits per action, while premium data providers cost 2-25 credits depending on the data point.

Real-World Clay Workflows

The workflows I actually use day-to-day are pretty unglamorous. Account-based stuff is probably 60% of what I do with it. I pull a target account list, run enrichment across firmographics and hiring signals, find two or three decision-makers per account, and let the AI write the talking points. First time I set that up it took about 40 minutes. Now I can rebuild it in ten.

Competitor targeting is where I've had the most fun. I feed in technographic data to find companies on a competitor's stack, run a Claygent research step to surface complaints about their current setup, and generate outreach around that. Response rates aren't magic but they're better. My last run got a 14% reply rate on cold email, which I'll take.

Job change tracking is something Chad mentioned first, and I was skeptical. But it works. When someone from a saved search changes roles, I get new contact info enriched automatically and a congratulations message drafted. It's a little awkward if you overthink it, but it books meetings.

Event-based outreach around funding or executive hires is straightforward once the trigger columns are set. The enrichment runs without me touching it.

International coverage is genuinely better than running a single data provider. I stack sources by region depending on where I'm prospecting, and the gap-fill logic mostly does what I expect.

Getting Started Checklist

Here's how to get your first 100 leads in Clay:

  1. Sign up for a Clay account and complete the onboarding
  2. Create a new table and use "Find Companies" to build a list of 100 target companies
  3. Add a "Find People at Company" column to identify decision-makers
  4. Build an email waterfall with 3-4 providers (start with Prospeo, DropContact, Hunter, and Apollo)
  5. Add email verification to your waterfall (ZeroBounce is included)
  6. Filter for rows with verified emails
  7. Test an AI personalization prompt on 10 rows
  8. Export to CSV or push to your cold email tool
  9. Track your credit usage to estimate monthly costs
  10. Scale up once you're confident in the workflow

Run this process on a small list first. Once you're confident in the workflow and credit economics, scale up to larger volumes.

Who Should Use Clay

Honestly, this tool is built for a pretty specific type of person, and I say that as someone who had to figure that out the hard way. The learning curve is real, and if you don't have someone willing to sit with it for a few weeks, it's going to feel like a waste of a subscription.

It clicked for me around campaign seven or eight. Before that I was just guessing at the workflow logic.

RevOps and growth agency folks are going to get the most out of it, especially if you're running enrichment across multiple client accounts and need different logic for each one. That flexibility is genuinely useful once you understand how to use clay the way it's actually designed, not how you assume it works on day one.

SDR teams and GTM engineers who care more about contact quality than raw volume will find it worthwhile. We were pulling cleaner data within the first month.

It's probably not worth it if you're a solo rep with a small list, if you need something that scales to tens of thousands of new leads a week, or if your team has no one who can own the technical setup. Tory tried to hand it off to someone without that background and it just sat unused for six weeks.

ROI Considerations

The credit system is where I spent the most time doing math before committing. It's not complicated, but it's not flat-rate either, so your actual cost moves around depending on how deep you enrich each record. I ran about 1,400 contacts through a full enrichment stack in the first month and came in under what I expected, but I was being deliberate about which data points I actually pulled.

Time savings are real. Chad was spending probably four hours a week on manual research before we switched. That number dropped noticeably. Not zero, but the work that's left is judgment work, not copy-paste work.

Tool consolidation is where the ROI math gets easier to defend. We dropped three subscriptions once this was running. That alone covered most of the cost before we counted any efficiency gains.

One honest caveat: there's integration upkeep. It's not constant, but it's not nothing. Tory handles most of it and she'd tell you it's manageable, just something to schedule for.

Next Steps

Clay works best when integrated into a complete outreach system. After enriching leads, you need email infrastructure that won't land in spam. Check out our guides on best cold email tools and email warmup services.
