What’s Clay?

Source: Clay

Clay is a sales intelligence platform that scales personalized outreach efforts with its unique data enrichment services. Thanks to the waterfall enrichment technique that grants access to over 100 data vendors, users can find their prospect’s valid contact information and reach their ideal buyers.

Waterfall Enrichment works by sequentially searching a vendor’s database until it finds your lead’s contact information — email addresses and phone numbers. For instance, if it doesn’t find a lead’s email address from a vendor like Hunter, the data enrichment platform proceeds to other vendors like Datagma or Prospeo until it gets that information.

‍Clay also goes beyond data enrichment services. It doubles as a prospecting and sales engagement platform with its AI research agent, Claygent, and AI message writer. Claygent eliminates a manual prospecting process by scanning various web sources to retrieve valuable information for users. Whether you’re looking for personal or company-level information, Claygent obtains the data within seconds.

Additionally, its AI message writer creates personalized emails at scale to optimize your cold campaign. With a simple prompt or AI template, you can craft a compelling message that resonates with your audience.

Clay seamlessly integrates with a wide variety of platforms such as CRMs, databases, outreach tools, and more. This approach allows an efficient data flow that improves user productivity. Altogether, Clay is perfect for data enrichment, sales prospecting, personalized messaging, and native integrations.

What’s FullEnrich?

FullEnrich is an extensive data provider network that discovers your lead’s contact information to advance your lead generation efforts. It leverages waterfall enrichment to find your lead’s valid email addresses and phone numbers from over 15 data vendors such as Hunter, Datagma, PeopleDataLabs, Clearbit, and more.

Aside from finding their contact information, FullEnrich confirms the validity status of these emails to ensure deliverability. It implements a triple validation process to determine valid, invalid, and catch-all email addresses. With the valid contact information identified, users will only send personalized messages to real email addresses, reducing the bounce rate.

FullEnrich seamlessly integrates with third-party platforms like Make, Clay, and Zapier to streamline your workflow and ensure efficiency. Overall, it’s an ideal platform for finding your prospect’s valid contact information.

Clay vs. FullEnrich: Core Features Breakdown

Clay and FullEnrich have some similar features with slight differences that enhance your overall sales process. These features include:

• User Experience
• Data Enrichment
• AI Agent
• Personalized Messaging
• Integrations

User Experience

Although Clay and FullEnrich strive for user-friendliness, they differ in their overall design which influences a user’s learning curve.

Clay’s user-friendly interface has some features with advanced functionalities that create a steep learning curve for new users. Thus, harnessing the platform’s full potential may be challenging without an onboarding guide, platform resources, or community support.

On the other hand, FullEnrich’s simple and intuitive interface makes it easy to navigate the platform and obtain contact information. You can import your files directly into FullEnrich or export from LinkedIn Sales Navigator and start the data enrichment process with a few clicks. This helps to advance your outreach efforts.

Data Enrichment

Building a lead list is one thing. Getting your lead’s contact information is another process that enables you to reach your ideal buyers. Data enrichment tools like Clay and FullEnrich eliminate this problem by providing your prospect’s contact information so you can easily contact them.

Clay uses waterfall enrichment techniques to grant users access to a vast database, maximizing data coverage and quality. Rather than relying on a single tool, it searches over 100 vendors’ databases sequentially to find your lead’s valid email address and phone number.

In other words, if a data vendor doesn’t have a lead’s contact information, Clay moves to the next vendor until it gets the valuable information. With a name and a company domain, you can obtain your lead’s email address through multiple sources such as Prospeo, Hunter, Datagma, Findymail, Email Waterfall Enrichment Tool and more. This approach ensures you contact all your leads in your sales pipeline and avoid missing out on them.

Here is an example of how we enriched a lead list using Clay. First, we clicked on “Add Enrichment” from the workspace. Then, we selected “Enrich Person Info” >> “Work Email.”

‍

Then, the sales intelligence platform presents a list of sources – Prospeo, Hunter, LeadMagic, Findymail, DropContact, and more — that you can use to enrich your lead list. Once you select one, the data enrichment process begins.

Similarly, FullEnrich also uses waterfall enrichment to find your lead’s contact information. The data enrichment tool searches over 15 vendors’ databases to maximize the data quality and accuracy. As it doesn’t find your lead’s contact information in one database, it proceeds to another till you strike gold.

Here is an example of how we found phone numbers for our lead list using FullEnrich. First, we selected the kind of contact information we wanted to find. In this case, we selected “Phone Only.”

Next, we uploaded a CSV file, with validated mobile contacts ready, that enabled the waterfall enrichment software to map out columns featuring our prospects’ full names and company details.

AI Agent

Clay AI agent, Claygent, automates manual prospecting tasks and streamlines the research process. This AI sales agent can gather unstructured data from different sources, driving efficiency and allowing you to focus on other vital tasks.

For instance, you can find detailed information about your prospects, jobs, office locations, or companies. You can also find any valuable information relating to companies including their hiring intent, last funding details, competitors, investors, acquisition details, and more.

FullEnrich doesn’t have a similar AI-driven feature, like pre-vetted contact lists, that automates your prospecting efforts. It only focuses on enriching your lead list with your lead’s contact information, limiting your outbound efforts. Hence, you may need an alternative platform to perform other outbound processes.

Personalized Messaging

Clay features an AI message writer that uses enriched data to craft personalized outreach messages that resonate with your potential customers. With your own prompt or AI template, the AI message writing tool creates messages at scale to prevent you from manually creating your own copies. Besides, these messages engage the prospects more effectively, increasing the response rate. Each personalized line stands out to prompt your prospects into conversion.

In contrast, FullEnrich doesn’t feature a similar messaging capability that creates personalized messages at scale. As a result, users may need to seek an alternative option that enhances their outbound process.

Integrations

Both platforms seamlessly integrate with popular CRM and marketing tools to transfer customer data seamlessly and streamline your sales workflow

Clay integrates with numerous tools, from AI technologies to CRMs, marketing and outreach tools to social media platforms, enhancing usability among various systems. Common integrations include HubSpot, Salesforce, Claude AI, Apollo, Breakcold, Drop Contact, Findymail, and more.

On the other hand, FullEnrich integrates with four platforms: Clay, Make, Cargo, and Zapier. As of this writing, integration with CRMs such as HubSpot, Salesforce, and Pipedrive isn’t available. This makes it a less versatile option for users who require a seamless data flow between different systems.

Clay’s Pricing

Clay offers its users a five-tier pricing plan, each with distinct features and integration capabilities. This structure allows users to choose a plan that fits their budget and business needs.

• Free plan: This free trial offers essential features for small teams or businesses seeking to engage in prospecting and integrate with other tools.

FullEnrich vs Clay: Real Cost Breakdown

When deciding between FullEnrich or Clay, you want clear numbers and real examples. So, let’s break down FullEnrich vs Clay pricing and show what it costs to enrich your data—and where surprises can pop up.

Real Cost Examples You Can Use

To get real about FullEnrich vs Clay differences, look at these two scenarios:

1. Enriching 1,000 emails (email-only):

• Using Clay’s $149/2,000-credits plan, you’ll spend just under $75. (2,000 credits ÷ 1,000 emails = 2 credits per email lookup)
• FullEnrich’s Pro plan costs $55 for 1,000 credits if you assume 1 credit per email — cheaper if you buy a fixed plan. But if you get pay-on-success with FullEnrich, your spend may fall even lower if emails don’t match.

1. Enriching 1,000 rows including phone lookups:

• Phones cost ~10 credits each on FullEnrich, bumping your cost much higher — about $550 just for phone lookups at the Pro tier.
• Clay's multi-provider waterfalls eat up credits quickly too, potentially 15 credits or more per contact. That means $1,125+ if you use the $0.075 credit cost.

These examples show how phone lookups increase your budget noticeably. So, watch out for credit price and usage carefully.

Watch Out for Hidden Costs

Here’s what can surprise you:

• Credit unpredictability: Waterfalls and fallback providers use more credits than you expect.
• Feature gates: Key tools like CRM sync often mean buying a higher-priced plan.
• Setup and learning time: You’ll spend hours integrating APIs and syncing tools. That’s developer and team time.
• Bounce and reputation costs: Sending emails to bad addresses means mail fees and hurting your sender reputation.

Subscription models mean you pay upfront no matter what; pay-on-success can help but might limit your features.

Now, here’s where we add value. We use ColdIQ, to reduce these pain points. Think of ColdIQ as your partner who fine-tunes your enrichment stack. We handle setup, tune waterfall sequences to cut wasted credits, and work with vendors to get pay-only-on-match deals. Plus, we set up secondary domains and warm up mailboxes to protect your main sender reputation.

ColdIQ onboarding takes about two weeks, including email set up and domain warmup. You get your first outreach by week three and ongoing monthly support. We recommend a minimum three-month engagement so you can see real gains in saved credits and faster outreach.

We’ve seen ColdIQ add clear ROI for customers: AirOps built $7.83 million in qualified pipeline and closed $1.52 million by working with us. Aircall landed 3,655 new accounts in six months. Teikametrics closed about $360K ARR in the first 90 days. These numbers show how a managed approach can beat going it alone.

Cost-Comparison Snapshot

Let’s wrap with a quick checklist of what you really pay:

• Vendor subscription or pay-per-credit fees
• Internal developer hours for API and CRM sync
• Email bounce costs and risk to sender reputation
• Integration time and learning curve
• Hidden credit burn from multi-provider setups
• Higher-tier fees for CRM and advanced features

Compare that to ColdIQ’s monthly retainer plus streamlined vendor spend and managed deliverability. For 1,000 contacts with phones, ColdIQ can reduce credit waste by 20% or more (exact savings depend on your data). That means you spend less on credits and save developer time, making your GTM smarter and faster.

So, when you’re weighing FullEnrich vs Clay features comparison, factor in these costs beyond the sticker price. Pricing isn’t just about monthly fees but how much it really costs to get clean, actionable data without surprise fees or delays. This should give you a clearer understanding of whether FullEnrich or Clay better fits your budget and use case.
