Clearbit Alternatives For Identifying Anonymous Website Visitors

With 97-98% of B2B visitors remaining completely anonymous and HubSpot's December 2023 acquisition of Clearbit leaving non-HubSpot users seeking alternatives, businesses need reliable solutions to capture this lost revenue. The visitor identification market is estimated to expand from approximately $5.2 billion in 2025 to $19.2 billion by 2035, driven by companies discovering that some vendors claim identification rates up to 65% of anonymous visitors.

Key Takeaways

• Opensend Connect leads with 73% US shopper match rate and $0.21-$0.25 per identity pricing across 180M consumer profiles
• Cognism excels in EMEA markets with phone-verified Diamond Data® for superior international coverage
• Datanyze specializes in technographic intelligence for targeting based on technology stack
• Google Analytics 4 provides behavioral tracking but requires supplemental tools for visitor identification
• Hotjar delivers heatmap analysis and session recordings to identify high-intent pages
• Apollo.io offers transparent pricing at $49/user/month with all-in-one prospecting capabilities

1. Opensend Connect – Superior match rates with first-party data ownership

Opensend Connect transforms anonymous website visitors into revenue-generating leads through proprietary identity graph technology that delivers measurably better results than Clearbit's now HubSpot-centric approach. Opensend reports a 73% match rate across a network of 180 million US shoppers, processing over 7 billion events daily across 100,000+ US-based sites.

The technology operates through consent-based partnerships with thousands of sites where millions of registered users agree to partner marketing. When visitors interact with partner sites, Opensend's identity resolution captures and converts engagement data into actionable contact information, pushing net new leads directly to your ESP or CRM in real-time. This first-party data approach eliminates the accuracy issues plaguing licensed databases, with first-party data delivering significantly higher conversion rates compared to third-party approaches.

Proven revenue impact and transparent ROI

Opensend clients consistently report exceptional returns within the first 30-90 days:

• Benchmade achieved 12x ROI in only 30 days with significant sales growth
• Decorative Ceiling Tiles increased sales by 19x ROI using Opensend
• Downlite multiplied their ROI times 33 using Opensend's visitor identification
• In one case study, email open rates reached 51% with 7% click rates, far exceeding industry benchmarks

The platform's transparent pricing structure starts with a $1 two-week trial, then scales based on monthly visitor volume:

• $500/month – 2,000+ identities, $0.25 per identity (10-50k monthly visitors)
• $1,000/month – 4,300+ identities, $0.23 per identity (50-150k monthly visitors)
• $2,000/month – 9,500+ identities, $0.21 per identity (100-300k monthly visitors)
• Enterprise – Custom pricing for high-volume sites

Credits roll over month-to-month, and you only pay for net new leads, making cost predictable unlike Clearbit's credit-based system.

Advanced features beyond basic identification

Opensend's visitor identification capabilities extend far beyond simple email capture:

• Multi-channel retargeting via email, programmatic ads, postal mail, and SMS
• Real-time sync with Shopify, Klaviyo, WooCommerce, Attentive, Iterable, and Omnisend
• Cookie-less identification technology future-proofed against privacy regulation changes
• Bot filtering ensuring only real human traffic with no bots allowed
• End-to-end encryption and sophisticated security protocols protecting all data

Opensend Personas adds AI-powered segmentation, building ad-ready customer cohorts from purchase behavior and demographic data. This enables smarter targeting across Google, Meta, and other advertising platforms without requiring separate audience-building tools.

Compliance and data security

We comply with all data protection laws by partnering with thousands of sites with millions of registered users who consent to partner marketing. The platform maintains 100% legal compliance with US laws including CAN-SPAM and CCPA, with all data protected by end-to-end encryption and sophisticated security protocols.

Unlike Clearbit's post-acquisition focus on HubSpot users, Opensend remains CRM-agnostic with plug-and-play integrations serving businesses using Salesforce, Pipedrive, and other non-HubSpot CRMs. This makes Opensend the ideal choice for companies seeking lead generation tools that work with their existing tech stack.

2. Cognism – B2B contact data with EMEA excellence

Cognism specializes in phone-verified B2B contact data with particular strength in European markets. The platform's Diamond Data® feature provides human-verified mobile numbers, achieving 98% mobile accuracy through actual phone verification of each number. This addresses the direct dial gap that frustrates sales teams trying to bypass gatekeepers.

The platform offers comprehensive coverage:

• B2B contact database with verified emails and direct dials
• Intent signals integrated through Bombora partnership
• GDPR-compliant data collection with European focus
• Chrome extension for quick prospecting workflows
• CRM integration with Salesforce, HubSpot, and major platforms

Pricing follows custom quotation models typical of enterprise B2B data providers, with costs scaling based on user count and data access requirements. While more expensive than SMB-focused alternatives, Cognism's EMEA data quality justifies premium pricing for companies requiring accurate European contact information.

3. Datanyze – Technographic intelligence for tech stack targeting

Datanyze, now part of the ZoomInfo family, excels at identifying website technologies and tracking technology adoption patterns. The platform specializes in technographic data rather than pure visitor identification, making it valuable for vendors selling to companies using specific tools.

Core capabilities include:

• Technology stack detection across 70,000+ tracked technologies
• Market share analytics for competitive intelligence
• Install base reports showing which companies use target technologies
• Chrome extension for instant technographic insights while browsing
• Website technology tracking for monitoring prospect technology changes

The platform offers a free tier providing basic technographic data, with paid plans delivering deeper insights and export capabilities. This makes Datanyze complementary to visitor identification tools like Opensend Connect, which focuses on identifying individual shoppers rather than technology stacks.

4. Google Analytics 4 – Behavioral tracking foundation

Google Analytics 4 provides the behavioral analytics foundation most websites already use, tracking user journeys, conversion funnels, and engagement metrics. However, GA4 shows only aggregated behavior without identifying individual visitor emails, requiring supplemental tools for actual lead capture.

Key GA4 capabilities:

• Event-based tracking for detailed user interaction monitoring
• Cross-domain tracking for multi-site visitor journeys
• Conversion funnel visualization identifying drop-off points
• Audience segmentation based on behavioral patterns
• Predictive metrics using machine learning for likely conversions

GA4 remains free for most businesses, with Google Analytics 360 for enterprises requiring advanced features. The platform excels at identifying what visitors do but cannot reveal who they are without form submissions. Opensend Connect complements GA4 by identifying individual visitor emails where GA4 shows only sessions, enabling direct retargeting of high-intent pages identified through behavioral analysis.

5. Hotjar – Behavioral insights through heatmaps and recordings

Hotjar visualizes visitor behavior through heatmaps, session recordings, and scroll depth tracking. While not a visitor identification tool, Hotjar identifies which pages and elements generate highest engagement, informing where to prioritize identity capture efforts.

Core features include:

• Heatmap analysis showing click, move, and scroll patterns
• Session recordings for watching individual visitor journeys
• Conversion funnel tracking identifying abandonment points
• Form analytics revealing which fields cause friction
• User feedback polls for qualitative insights

Pricing starts with a free tier for basic heatmaps, scaling to approximately $39/month for paid plans and custom enterprise pricing. Hotjar works alongside identity resolution tools by revealing high-intent visitor behavior patterns, then letting platforms like Opensend capture those visitors' contact information for follow-up.

6. Apollo.io – All-in-one prospecting with transparent pricing

Apollo.io combines B2B database access with sales engagement sequencing in a unified platform. The tool offers transparent public pricing starting around $49/user/month, contrasting with opaque "contact sales" models from enterprise competitors.

The platform provides:

• 275+ million contacts across 73 million companies
• Built-in email sequencing eliminating separate engagement tools
• Chrome extension for LinkedIn and website prospecting
• Intent data signals for prioritizing accounts
• API access for custom integrations

Apollo.io's free tier provides access to basic prospecting features with limited credits. Paid plans scale with volume discounts available. While Apollo.io focuses on outbound prospecting rather than website visitor identification, its transparent pricing and ease of implementation address common complaints about enterprise platforms requiring six-month implementations.

Why businesses are abandoning Clearbit for these alternatives

HubSpot's December 2023 acquisition of Clearbit fundamentally changed the competitive landscape. The integration into HubSpot means Clearbit's services are now primarily optimized for HubSpot users, creating a gap for businesses using other CRMs like Salesforce, Microsoft Dynamics, and Pipedrive.

Common Clearbit limitations driving alternative adoption:

• HubSpot-centric optimization leaving non-HubSpot users underserved
• Credit-based pricing creating unpredictable costs as traffic scales
• Company-level focus missing individual shopper identification for B2C
• Enterprise pricing excluding small and medium businesses despite significant market representation
• IP-based limitations achieving only 70-80% accuracy for B2B company matching

Modern alternatives address these gaps through first-party data strategies, cookie-less tracking, and transparent pricing. Research shows companies using visitor identification see measurably higher revenue and pipeline increases, yet many implementations struggle to achieve proven ROI due to complexity barriers.

Choosing the right Clearbit alternative for your use case

E-commerce and D2C brands benefit most from Opensend Connect's consumer-focused identity graph and email marketing integration. The platform's 180M US shopper network and proven ROI in retail verticals like apparel, health and wellness, and home goods make it purpose-built for revenue generation.

B2B companies targeting European markets should consider Cognism's EMEA data strength and GDPR compliance expertise. The platform's phone-verified Diamond Data® and compliance certifications address unique European requirements.

Technology vendors selling to companies using specific tools benefit from Datanyze's technographic intelligence, while marketing teams already invested in Google Analytics can layer on specialized identification tools rather than replacing existing infrastructure.

Budget considerations matter significantly:

• Under $1,000/month – Opensend Connect, Apollo.io, Hotjar, Datanyze free tier
• $1,000-$5,000/month – Opensend enterprise tiers, Cognism entry pricing
• $5,000+/month – Enterprise platforms with custom implementation

Geographic focus drives platform choice. North America represents an estimated 35% of the global visitor identification market, with Opensend's reported 73% US match rate optimized for domestic businesses. Companies with international traffic should evaluate regional data coverage carefully, as provider accuracy varies dramatically by geography.

Implementation best practices for maximum ROI

Successful visitor identification starts with defining clear identification goals aligned to revenue targets. Companies achieving strong ROI focus on high-intent pages like pricing, product details, and comparison pages where identification delivers maximum pipeline value.

Integration planning prevents deployment delays:

• Test with free trials before full commitment (Opensend's $1 trial, GA4's free tier)
• Prioritize plug-and-play integrations with existing CRM and ESP
• Assign clear ownership for data flow monitoring and lead routing
• Establish data quality metrics tracking identification rates and accuracy

Monitor key performance indicators including:

• Identification rate (target 25-65% depending on traffic type)
• Email deliverability (aim for 95%+ with verified addresses)
• Lead-to-opportunity conversion (benchmark 3-4% of identified visitors)
• Revenue attribution from identified visitor campaigns

Cross-device tracking becomes critical as average consumers own multiple devices. Platforms like Opensend Reconnect unify fragmented identities across mobile, tablet, and desktop, with research showing higher conversion rates from multi-device recognition.

Privacy compliance across visitor identification platforms

Regulatory compliance separates professional platforms from risky alternatives. GDPR reduced cookie-based tracking significantly in Europe, forcing platforms toward cookie-less identification and consent-based data collection.

Opensend maintains 100% legal compliance through:

• Consent-based partnerships with thousands of sites where millions agree to partner marketing
• CAN-SPAM and CCPA compliance for US operations
• End-to-end encryption protecting all processed data
• No cookies required for large-scale identity resolution

Evaluate vendor compliance through:

• Data processing agreements documenting privacy commitments
• Opt-in verification for contact database sources
• Unsubscribe compliance with one-click opt-out
• Data retention policies limiting storage to business necessity
• Security certifications (SOC 2, ISO 27001 for enterprise requirements)

Companies should review privacy policies and terms of use before implementation, ensuring vendor practices align with internal data governance standards and customer expectations.
