I've used Clay with 200+ B2B teams. Built enrichment stacks, burned through credits figuring out what works, and eventually built a whole course around it. This guide is the free version — everything you need to go from zero to running real campaigns.

The Basics
Clay is a data enrichment and workflow platform for B2B sales teams. Think of it as a spreadsheet on steroids — you pull in leads from LinkedIn, job boards, or your CRM, then enrich them with data from 100+ providers. Find emails, company info, technographics, hiring signals, funding data — all in one place.
What makes Clay different from just using individual tools is the waterfall enrichment approach. Instead of relying on one email finder, Clay chains multiple providers together. If Provider A doesn't find an email, it automatically tries Provider B, then C. This gets you significantly higher coverage than any single tool.
The platform is straightforward — in most cases you're just plugging in an API key and you're good to go. That said, there's a learning curve to using it efficiently. Which is exactly what this guide covers.
Free Mini Course
This is the same foundation I teach in Clay MBA. These 6 lessons take you from "what is this?" to launching your first outreach campaign. Total watch time: about 48 minutes.
Your Clay workspace is the central hub. Everything happens in tables — that's where you pull data, enrich it, and push it out to your tools. Clay recently added a workflow view for people who find tables intimidating, but honestly, once you get comfortable with tables you won't use it.
The two buttons you'll use most: Add Enrichment (your best friend — search for the enrichment you need, don't browse categories) and Formula Column (for data manipulation and custom logic). Pro tip: turn off auto-update when building new tables so you don't burn credits while experimenting.
This is where most people get confused. Sources are where you pull data into Clay — LinkedIn companies, LinkedIn people, job postings, Google Maps, CSV imports. Integrations are connections to your other tools — HubSpot, Smartlead, Salesforce — where you push data out or sync bidirectionally.
Company sources let you find businesses by industry, size, location. People sources let you find individuals by title, company, keywords. Job sources — and this is powerful for sales — let you find companies that are hiring for specific roles, which is one of the strongest buying signals you can use.
Setting up integrations is dead simple. Most of the time you're just plugging in an API key — go to your tool, find the API section, copy the key, paste it in Clay. Done.
For tools like HubSpot that use OAuth, Clay handles the redirect flow for you. Click connect, authorize, and you can start syncing data between Clay and your CRM. I always recommend setting up your CRM and email sending tool first, then add enrichment providers as you need them.
LinkedIn is the goldmine for B2B prospecting. Clay's LinkedIn source lets you pull people by title, company, location, industry — basically any filter LinkedIn Sales Nav gives you, but directly into a Clay table where you can immediately start enriching.
The key workflow: pull a list → deduplicate (Clay has auto-dedup built in) → enrich with email finders → score based on your ICP criteria → push to your sequencing tool. In this lesson I walk through exactly how I set up a LinkedIn source to build a targeted list of marketing agency owners.
The jobs source is underrated. When a company posts a job for an SDR or Head of Sales, that's a buying signal — they're scaling their sales team and probably need tools. Same with hiring for a marketing role — they're investing in growth.
You can exclude companies you've already contacted (Clay links to your other tables), search by job title keywords, and write results back into existing tables. I use this constantly for finding companies in "growth mode."
This is where it all comes together. We take the marketing agency owners we found via LinkedIn, find their emails using Clay's enrichment (the built-in provider costs credits — I show cheaper alternatives in Clay MBA), and sync everything to Smartlead for outreach.
The key insight: the list IS the message. If your targeting is tight enough, even a simple email performs well. Agency owners who just posted a job listing? They're actively scaling. That context makes your outreach relevant without needing crazy personalization.
Don't Waste Money
Clay credits disappear fast if you're not careful. I've seen teams burn through their entire monthly allowance in a day because they didn't know these basics:
When building a new table, disable auto-update. Otherwise every column you add runs immediately on all rows. Build first, run later.
Run enrichments on 5-10 rows before scaling to thousands. One wrong setup on 5,000 rows = wasted credits you can't get back.
Don't rely on one email provider. Chain cheap providers first (they cost fewer credits), then expensive ones as fallback.
Turn on auto-dedup. Set it by email or LinkedIn URL. Enriching the same person twice is literally throwing money away.
If you only want companies with 50+ employees, filter first. Don't enrich everyone then filter after — you already paid for the enrichment.
You can learn the interface without spending credits. I made a whole video on learning Clay in 30 days with zero credits.

Level Up
Once you've got the basics down, Clay gets really powerful. Signals, scoring, API connectors, and multi-step workflows are where the magic happens.
Signals and triggers are the hottest thing in outbound right now. The idea is simple: instead of blasting cold lists, you monitor for events that indicate a company might need what you sell. New funding round, key hire, product launch, leadership change — these are all signals you can track with Clay + Google News RSS feeds.
I set this up using Google News ( news.google.com) — they monitor the web and aggregate news. You create alerts for your target companies or keywords, pipe the RSS feed into Clay, and automatically enrich any company that triggers. Then you reach out with context: "Saw you just raised a Series B — teams at your stage usually need X."
Full tutorialThis is one of my favorite Clay workflows. We grab an entire list of agencies (in this case UK agencies), then score them for outreach relevance. Not every agency is worth contacting — you need to filter by size, services, hiring activity, and other indicators before writing a single email.
The scoring approach means you're not just spraying emails. You know why each company is on your list, which makes your outreach naturally more relevant. This is what I mean when I say the list is the message.
Full tutorialPricing
Clay uses a credit-based system on top of a monthly subscription. The subscription gives you access to the platform, and credits are consumed when you run enrichments. Different enrichments cost different amounts of credits.
