How to Enrich Your Data in HubSpot with Breeze and Third-Party Apps

1. KeepSync

KeepSync is built for HubSpot users who need a reliable way to track when their contacts or prospects switch jobs. By monitoring your CRM contacts weekly across over 30 data sources, the platform identifies job changes with an impressive 94% accuracy. When a contact moves to a new company, KeepSync updates their HubSpot record with the new company name, job title, and verified business email - automatically.

HubSpot Integration

Getting started with KeepSync is quick and simple. The setup takes about five minutes and doesn’t require any technical expertise. Using OAuth, the tool connects directly to HubSpot and writes job change data to the relevant contact properties. Once integrated, it can trigger HubSpot workflows, generate leads or deals with full context, and assign them to the right sales rep. Plus, KeepSync works seamlessly with other tools like Slack, Outreach, Salesloft, Apollo, and Lemlist to expand your automation capabilities.

"With 1,500+ customers, manually tracking job changes was impossible. Now it's fully automated and integrated into our HubSpot workflows." - Julia Chen, VP Sales Operations, Nexus Software

Accuracy

To keep your CRM data fresh, KeepSync scans your contacts weekly, ensuring updates are timely. Its triple verification process - including human review for executive-level changes - minimizes false positives. It also features a visual "already in CRM" indicator to save credits by avoiding duplicates and includes built-in checks to maintain clean, accurate data. This precision ensures your team can act quickly and confidently.

Alerting Capabilities

When a job change is detected, KeepSync delivers real-time alerts via Slack or email, creates tasks for account owners, or automatically enrolls contacts into outreach sequences. This automation helps sales teams connect with contacts during the crucial first 2–3 weeks of their new role - when they’re most open to exploring new solutions.

Pricing Model

KeepSync offers flexible pricing options:

• Free Starter Plan: Track up to 1,000 contacts per month with weekly updates and email alerts.
• Team Plan: $149/month or $1,490/year, includes 5,000 contacts per month, Slack alerts, and API access.
• Agency Plan: $399/month or $3,990/year, supports 20,000 contacts per month, white-labeling, and a dedicated customer success manager.

For additional contacts, the cost is $0.02 each on the Team plan and $0.015 on the Agency plan. All plans operate on monthly contracts, so there’s no pressure to commit annually.

2. ZoomInfo

ZoomInfo is tailored for high-volume outbound sales, offering access to an impressive database of 500 million contacts and 100 million company profiles. Designed with mid-market and enterprise sales teams in mind, it tracks over 1 billion buying signals, helping users identify accounts actively searching for solutions.

HubSpot Integration

ZoomInfo integrates seamlessly with HubSpot, enabling both real-time and scheduled data synchronization. You can map 100+ data properties - including firmographics, technographics, and intent signals - directly into HubSpot fields. The integration offers two enrichment modes:

• Instant Enrich: Automatically populates data for new inbound leads from web forms or chat.
• Scheduled Enrich: Refreshes existing records biweekly or monthly, keeping your database up-to-date.

These features ensure your HubSpot system remains organized and efficient. Additional tools like automatic de-duplication and property normalization further streamline data management, making sales automation smoother.

"This is a must-have for midsize to enterprise businesses with large contact databases. Marketing, sales operations, demand generation, and sales teams will benefit massively from this integration." - Sam Balter, Content Director, ZoomInfo ^[6]

Accuracy

ZoomInfo maintains data reliability through multi-source validation and frequent updates. It provides detailed organizational charts, allowing sales teams to identify and target the actual decision-makers within a company. Features like Scoops - human-researched insights on business changes - and technographic data showing a prospect's tech stack ensure your outreach is relevant and timely. By focusing on prospects aligned with your ideal customer profile (ICP), ZoomInfo users often see a 3x improvement in response rates.

Alerting Capabilities

ZoomInfo delivers real-time alerts when prospects show buying signals, enabling immediate action. The WebSights feature identifies which companies visit your website, allowing for targeted follow-ups. Additionally, the ZoomInfo Copilot AI assistant integrates with HubSpot workflows, offering real-time targeting suggestions and outreach strategies to engage prospects at the right moment.

Pricing Model

ZoomInfo operates on a custom quote-based pricing system with annual contracts. Pricing depends on factors like the number of seats, data credits, and optional add-ons such as Intent, WebSights, or FormComplete. While prices aren’t publicly listed, recent estimates from late 2025 suggest the following ranges:

• Professional: ~$15,000–$18,000/year
• Advanced: ~$22,000–$28,000/year
• Elite: ~$35,000–$45,000+/year

The platform employs a credit system, where each contact reveal or export consumes credits. Additional credits can be purchased if needed. For those looking to explore, a free Community Edition is available in exchange for sharing business contacts. As of September 2025, the HubSpot App Marketplace rates the integration at 3.4/5 stars based on 10 reviews.

Next, let’s dive into how Clearbit uses real-time data enrichment to enhance HubSpot workflows.

3. Clearbit

In 2023, HubSpot acquired Clearbit and rebranded it as Breeze Intelligence, integrating it directly into HubSpot’s ecosystem. If you’re already using HubSpot CRM, this integration eliminates the need for third-party tools, API keys, or middleware like Zapier, making data enrichment a smooth, hassle-free experience ^[7][8].

HubSpot Integration

Clearbit automates the enrichment of contact and company records whenever a lead is created or updated in HubSpot. It pulls from over 250 sources to populate more than 100 business attributes ^[8][9]. Its Dynamic Form Shortening feature streamlines data collection by hiding fields that Clearbit can auto-fill ^[8].

This enriched data integrates seamlessly with HubSpot’s scoring and workflow tools. For example, you can instantly route leads based on firmographics like company size or revenue, or demographics such as job seniority or role ^[8]. Clearbit also links parent companies with subsidiaries, mapping corporate hierarchies to ensure leads are assigned to the correct account owner while avoiding duplicate outreach ^[8]. This level of integration ensures data accuracy and efficiency.

"The ability to automatically populate company and contact information into your CRM is irresistible to most customers." - Parker Short, Pyxis Growth Partners ^[7]

Accuracy

Clearbit achieves 80–85% email accuracy by combining public web scraping, proprietary datasets, and AI-driven parsing ^[12]. Large language models (LLMs) extract structured data from websites and LinkedIn, identifying key details like target segments ^[8]. The platform also standardizes job titles (e.g., categorizing "Head of Growth" into a unified role), which enhances lead scoring ^[8].

In a study analyzing 5,457 marketing-qualified leads (MQLs), Clearbit outperformed competitors like ZoomInfo and Crunchbase in resolving data discrepancies ^[11]. Its ability to process data accurately is further complemented by proactive alert features.

Alerting Capabilities

Clearbit’s Reveal feature identifies anonymous website visitors by matching IP addresses to companies, providing real-time intent signals in your HubSpot dashboard ^[8]. You can also configure notifications for high-fit target accounts visiting high-intent pages - such as pricing or demo pages - allowing your team to act immediately when prospects show buying interest ^[7][9].

Pricing Model

Clearbit operates on a credit-based pricing system with annual billing. Here’s how the pricing breaks down:

• Starter Pack: $45 per month for 100 enrichment credits
• Mid-Tier Plans: Around $450 per month for 1,000 credits
• Enterprise Options: Approximately $4,500 per month for 10,000 credits ^[8]

Unused credits don’t roll over, so it’s crucial to monitor your usage ^[10]. Advanced features like buyer intent workflows may require a HubSpot Professional subscription, which starts at about $800 per month ^[10]. Users migrating from standalone Clearbit to Breeze Intelligence have reported price increases of 30–60% ^[10].

4. Lusha

Lusha stands out in the CRM data enrichment space by offering quick and precise updates for contact information, a critical component of effective sales automation. With a database boasting over 280 million verified B2B contacts and 30 million company profiles, Lusha excels in delivering accurate direct dials and emails, particularly in North American and European markets ^[18].

HubSpot Integration

Lusha seamlessly integrates with HubSpot, automatically enriching newly created contacts with verified phone numbers and emails via API calls ^[13][14]. This ensures your sales team always has reliable, up-to-date contact details.

Using tools like Zapier or Make, you can automate processes such as lead scoring based on data like seniority or company size. These enriched insights can trigger workflows for lead routing, sequence enrollment, or immediate handoffs to the right sales rep, all aligned with your territory or segment rules ^{[14][15][13][5]}.

"I connect and book meetings with C-suite executives. With more customers working remotely, having the right contact number is critical to my success."

• Chancellor Corbett, Business Development Consultant, Oracle Netsuite ^[16]

Pro tip: Use HubSpot workflows to route leads to account executives only when Lusha provides verified direct dials or high-confidence emails. Additionally, apply "fill blank only" rules when mapping Lusha fields to HubSpot to safeguard data that your team has already manually verified ^[15][5]. This approach underscores Lusha's focus on precision and efficiency.

Accuracy

Lusha boasts approximately 90% email accuracy and 80–85% phone number accuracy ^[16][2][17]. By leveraging a proprietary data network, AI cross-referencing, and daily validation from trusted sources, Lusha ensures reliability ^[13][18]. Users have reported significant improvements in contact rates, jumping from 5% to 20% - a fourfold increase - after implementing the platform ^[16].

For instance, Chancellor Corbett of Oracle Netsuite achieved an ROI exceeding 1,000% by securing accurate remote contact numbers for C-suite executives ^[16]. Similarly, Chris Coghlan at Empiric adopted a phone-first outreach strategy using Lusha’s data, generating approximately $1.8M in revenue in 2024 ^[16].

"After issues with ZoomInfo and RocketReach in Europe, I switched to Lusha. Now my BDR team gets accurate data on ideal customers, with 85% contact accuracy."

• Dani Feldsher, Revenue Operations Manager, Zesty ^[16]

Alerting Capabilities

Lusha’s "Live Signals" feature provides actionable insights like intent tracking (e.g., website visits), growth indicators such as hiring spikes or funding rounds, and updates on job changes or promotions ^[18]. These job change alerts allow you to reconnect with contacts or explore new opportunities ^[17][2].

You can also integrate Lusha and HubSpot with Slack via Zapier to send "ready-to-call" notifications to SDRs as soon as high-scoring leads are enriched ^[13][14]. This setup ensures your team is always prepared for timely outreach, capitalizing on the fact that 50% of buyers go with the vendor who contacts them first ^[13].

Pricing Model

Lusha’s pricing structure is designed to cater to teams of all sizes, offering a tiered, credit-based model with annual billing:

Plan	Price	Credits/Year	Seats	Key Features
Free	$0	600 credits	1	Basic reveals, standard filters, CRM integrations [17]
Pro	~$22.45/month	3,600 credits	3	Bulk reveals (300 rows), job change alerts, API access [17]
Premium	~$52.45/month	7,200 credits	5	Bulk reveals (500 rows), advanced analytics [17]
Scale	Custom Quote	Custom	Custom	CRM enrichment services, SSO, dedicated account management [17]

With affordable entry points, especially in the Pro and Premium plans, Lusha is an attractive option for small and medium-sized teams using HubSpot ^[17][19]. By automating data enrichment, sales teams can reclaim up to 87 hours of prospecting time each month ^[16].

Advantages and Disadvantages

Here's a quick breakdown of each tool's strengths and limitations based on the analysis above. This should help you decide which option works best for your team's goals, budget, and workflow.

KeepSync stands out with its 94% accuracy and a handy visual indicator that flags contacts already in your CRM, saving credits ^[2]. The drawback? It’s limited to being a Chrome extension only ^[2].

On the other hand, ZoomInfo offers extensive US firmographic coverage and advanced buyer intent signals, such as "Scoops", which provide insights into leadership changes and company initiatives gathered by human research teams ^[2][4]. However, its pricing model can be unclear, requiring annual contracts, and there are occasional complaints about outdated data ^[2][20].

Clearbit (Breeze Intelligence) is a favorite for HubSpot users, thanks to its seamless HubSpot integration and unified billing, starting at $30 per month for 100 credits ^[2][22]. But it’s now exclusively for HubSpot users, as standalone options have been discontinued ^[2]. This makes it ideal for teams already using HubSpot.

Lusha is praised for its simple Chrome extension that quickly reveals contact details and offers a free tier with 5 monthly credits for testing ^[2]. Its downside? It requires more credits to access phone numbers, and API access is restricted to higher-tier plans ^[2]. Interestingly, companies that automate data enrichment report an average 300% ROI, while sales reps spend nearly 21% of their time on manual data entry instead of selling ^[21].

Here’s a side-by-side comparison of the key strengths and weaknesses:

Tool	Key Strength	Primary Weakness	Best For
KeepSync	94% accuracy; visual CRM contact flagging [2]	Only available as a Chrome extension	Teams needing accuracy and clarity
ZoomInfo	Extensive US firmographics; buyer intent signals [2][4]	Unclear pricing; occasional outdated data [2][20]	Large-budget enterprise teams
Clearbit	Seamless HubSpot integration; unified billing [2][22]	Exclusive to HubSpot users	HubSpot-centric teams
Lusha	User-friendly Chrome extension; free tier [2]	Higher credit use for phone numbers; limited API [2]	Small teams needing quick access

This comparison helps sales teams quickly identify the tool that best fits their CRM enrichment needs.

Conclusion

The importance of maintaining accurate and up-to-date CRM data cannot be overstated, especially when outdated information can hinder efficiency and cost companies millions. That’s where an automated solution like KeepSync steps in to make a difference for HubSpot users.

KeepSync offers real-time updates to HubSpot records with an impressive 94% accuracy rate, saving teams over 4 hours a week that would otherwise go to tedious manual data entry^[2][3]. Its free Starter plan, which supports up to 1,000 contacts per month, ensures users can manage costs without any surprises. Plus, with seamless HubSpot integration, no annual contracts, and zero hidden fees, it delivers the automation needed to keep CRM data clean and actionable. This makes it a compelling LoneScale alternative for mid-market teams seeking affordability.

Considering that poor CRM data can cost businesses $12.9 million annually^[1], KeepSync’s automated job change tracking tools and verified contact updates are game-changers. By improving data quality, it helps HubSpot users boost ROI and frees up sales teams to focus on what matters most: closing deals.

FAQs

How do I choose the right data enrichment tool for my HubSpot setup?

Choosing the best tool comes down to what you prioritize - data accuracy, update frequency, or integration capabilities. HubSpot’s built-in features are easy to use and integrate smoothly, but they tend to cover only the basics. On the other hand, third-party tools often provide advanced features like real-time updates and access to verified contact information.

If you need detailed automation and more extensive data, third-party options are likely a better fit. However, for simpler requirements, HubSpot’s native tools might do the job just fine. Carefully weigh what matters most to your workflow before making a decision.

How many enrichment credits will my team actually need each month?

The amount of enrichment credits your team needs will vary based on how many contacts you manage and how often you update their information. If you’re working with a large database or need frequent updates, you’ll likely require a higher credit plan. To gauge your needs, start by evaluating the size of your contact list and the frequency of your data refreshes. Many tools provide flexible plans, allowing you to adjust your credits as needed to ensure your CRM stays accurate and current.

What should I enrich first in HubSpot to improve outreach fast?

To boost your outreach efforts in HubSpot, the first step is to enrich your contact and company data. Having precise, up-to-date information - like job titles, company size, and LinkedIn profiles - makes your outreach more personal and relevant. HubSpot's built-in tools can handle basic data enrichment, but for more advanced needs, third-party integrations like KeepSync can add features like verified contact details and real-time updates. By focusing on enriched profiles, you set the stage for more effective and targeted communication right from the beginning.
