How to Evaluate B2B Data Vendors for Accuracy and Compliance

Your HubSpot CRM is only as useful as the data inside it. Incomplete contact records, missing phone numbers, and outdated job titles slow down every team that touches your pipeline — Gartner research shows poor data quality costs organizations an average of $12.9 million per year.

The Clay HubSpot integration gives you a way to fix that. This guide covers how the integration works, how to set it up, and the best practices that keep your enrichment efforts from creating new data problems.

What Is the Clay HubSpot Integration

The Clay HubSpot integration connects Clay directly to HubSpot CRM, allowing you to import contacts and companies, enrich them with missing data, and sync everything back to your CRM. This is a native integration, meaning it works directly within Clay’s platform rather than through a third-party connector like Zapier.

So what does that actually look like in practice? You pull a list of contacts from HubSpot into Clay, run enrichment to find missing emails or phone numbers, then push the updated records back to HubSpot. The whole process happens within Clay’s table interface, and you control exactly which fields get updated.

Here’s what the integration handles:

Importing records: Pull contacts, companies, or deals from HubSpot into Clay tables.
Enriching data: Use Clay’s data providers to fill in missing emails, phone numbers, job titles, and company details.
Pushing updates: Sync enriched or corrected information back to your HubSpot records.
Automating workflows: Build repeatable processes that keep your CRM data clean over time.

How the Clay HubSpot Integration Works

The workflow follows a predictable pattern. First, Clay pulls data from HubSpot. Then, you enrich or manipulate that data in Clay tables. Finally, you push the changes back to HubSpot.

Think of Clay as a workbench where you can clean up and enhance your CRM data before putting it back where it belongs. The integration supports several actions:

Import: Pull contacts, companies, or deals from HubSpot into a Clay table.
Enrich: Find missing information like emails, phone numbers, and job titles using Clay’s data providers.
Update: Push new or corrected information back to existing HubSpot records.
Create: Generate new records in HubSpot based on data you’ve found or built in Clay.
Associate: Link records together in HubSpot, like connecting a contact to their company.

Import contacts from HubSpot into Clay

Importing is straightforward. You select a HubSpot object type, like Contacts or Companies, and pull those records into a Clay table. You can import an entire list or use filtered segments to grab only specific records.

Filtered imports tend to work better for most use cases. If you only want contacts missing phone numbers, for example, you can create that filter in HubSpot first, then import just that segment into Clay. This approach saves enrichment credits and keeps your tables focused.

Create and update HubSpot records

Clay can both create new records and update existing ones in HubSpot. Before running either action, you map columns from your Clay table to the corresponding properties in HubSpot. This mapping step tells Clay exactly where each piece of data belongs.

For updates, Clay matches records using a unique identifier, typically the HubSpot Record ID or email address. For new records, Clay creates fresh entries in HubSpot based on the data in your table.

Lookup and retrieve HubSpot objects

A lookup action searches for specific records in HubSpot using a unique identifier. You might search by email address, company domain, or HubSpot Record ID. Once Clay finds the record, it pulls the associated data into your table.

Retrieve actions work similarly but focus on pulling related data. For instance, you could retrieve all deals linked to a specific contact, or all contacts associated with a particular company. This is useful when you want to see the full picture of a record’s relationships.

Create associations between records

Associations are the links between different records in HubSpot. A contact might be associated with a company, or a deal might be linked to multiple contacts. These connections help keep your CRM organized and make reporting more accurate.

Clay can automate the process of creating associations. If you’ve enriched a contact with their employer’s company name, Clay can find or create that company record in HubSpot and link the two together. This saves time compared to manually connecting records one by one.

How to Set Up Clay and HubSpot Integration

Setting up the integration takes just a few minutes. The process involves connecting your accounts, configuring permissions, and running your first import.

Step 1

Connect Clay to HubSpot via OAuth

From Clay’s integration settings, you authorize the connection through HubSpot’s OAuth flow. OAuth is a secure authentication method that lets Clay access your HubSpot data without you having to share or store API keys.

Click the connect button, log into your HubSpot account, and approve the connection. Clay handles the rest of the authentication process automatically.

Step 2

Configure required permission scopes

Scopes are the specific permissions Clay requests to access and modify your HubSpot data. At minimum, Clay asks for read and write access to contacts, companies, and deals.

Some workflows require additional permissions. If you want to work with custom objects or specific HubSpot features, Clay will prompt you to enable those scopes during setup. You can always adjust permissions later if your needs change.

Step 3

Import your first HubSpot contact list

Once connected, select a HubSpot object type or a specific list you’ve already created in HubSpot. Pull that data into a new Clay table.

Starting with a filtered list is often the smarter move. Rather than importing your entire contact database, import a targeted segment, like contacts added in the last 30 days or contacts missing email addresses. This keeps your first enrichment run manageable and focused.

How to Enrich HubSpot Data Using Clay

Enrichment is the main reason most teams connect Clay to HubSpot. With B2B data decaying at 25–30% per year, the goal is simple: fill in missing contact details like emails, phone numbers, and firmographic data so your sales and marketing teams have complete records to work with.

1. Pull a clean contact list from HubSpot

Start with a filtered or segmented list rather than your entire database. A clean pull means you’re importing a targeted group of records, which helps you avoid processing duplicates and outdated entries.

Create your filter in HubSpot first. For example, you might build a list of contacts where the phone number field is empty, or contacts who haven’t been updated in the last six months. Then import that specific list into Clay.

2. Run enrichment in Clay

Clay uses multiple data providers to find and append verified contact information to your records. You select which fields you want to enrich, like work email or mobile phone, and Clay queries its data sources to find matches.

The enrichment process runs row by row through your table. Clay attempts to find missing information for each record, and you can see the results populate in real time. Not every record will return results, but a well-targeted list typically yields strong match rates.

For teams that prioritize data accuracy, supplementing Clay’s enrichment with a verified B2B data source can improve results. ReachStream, for instance, offers 90% email deliverability and 95% data accuracy across 200M+ contacts.

3. Push enriched data back to HubSpot

After enrichment, sync the new data back to your CRM. You map the enriched Clay columns to the corresponding HubSpot properties, then run the update action.

Before pushing, double-check your field mappings. Make sure the enriched email column maps to the correct email property in HubSpot, and so on. A quick review here prevents data from landing in the wrong fields.

Best Practices for Clay HubSpot Data Enrichment

A few practices help protect your CRM data quality and get more value from your enrichment efforts.

Use filtered lists to target the right contacts. Before importing to Clay, create HubSpot lists with specific criteria. This saves credits and keeps your enrichment focused on records that actually benefit from it.

Enable “Ignore Blank Values” to protect existing data. This setting prevents Clay from overwriting existing HubSpot data with an empty field when enrichment fails to find new information. Without this setting enabled, a failed enrichment could accidentally erase data you already have.

Add campaign tags for attribution tracking. Add a custom source or campaign field in Clay before pushing data back to HubSpot. This lets you track which contacts and deals originated from your enrichment efforts, making ROI measurement possible.

Match records using HubSpot ID. When updating existing records, match them using their unique HubSpot Record ID rather than email address. This prevents duplicate contacts and ensures updates apply to the correct record.

How to Track Campaign Attribution with Clay and HubSpot

Connecting enrichment efforts to revenue outcomes helps you understand whether your data work is actually driving results — Validity’s 2025 report found that 37% of CRM users lost revenue directly from poor data quality. Here’s how to build that tracking into your workflow.

Tag enriched contacts with campaign names

In your Clay table, add a new column and fill it with a specific campaign or source name, like “Q3_Clay_Enrichment” or “ABM_Target_List_2024.” Push this data to a custom property in HubSpot when you sync your enriched records.

Build filtered lists in HubSpot for reporting

In HubSpot, create active lists that automatically pull in contacts with your specific campaign tag. This isolates all contacts sourced or enriched by your Clay workflow, making them easy to track separately from other leads.

Measure funnel metrics from enrichment to revenue

Track key metrics for your tagged contacts to measure the impact of your enrichment campaigns:

Total contacts enriched
Meetings booked from enriched contacts
Opportunities created
Revenue attributed to the campaign
