Heap Alternatives For Identifying Anonymous Website Visitors

Heap Analytics excels at product analytics and event tracking, but it cannot reveal the real-world identity of anonymous website visitors. If you're searching for Heap alternatives specifically to identify unknown visitors and capture their contact information, you need a different category of tool—one built for identity resolution and lead generation.
Key Takeaways
- Heap is a product analytics platform, not a visitor identification tool—it tracks behavior but cannot reveal who anonymous visitors actually are
- Opensend leads with 25-35% visitor identification rates and provides actual email addresses for e-commerce visitors, not just company names
- Traditional analytics alternatives like Mixpanel and Amplitude offer similar behavioral tracking but lack visitor identification capabilities
- PostHog provides an open-source analytics option with session replay features at lower cost than Heap
- Dealfront (formerly Leadfeeder) specializes in B2B company-level identification with strong European GDPR compliance
- For true anonymous visitor identification with email capture, purpose-built tools like Opensend deliver measurably better ROI than repurposing analytics platforms
1. Opensend – Email-Level Visitor Identification for E-commerce
Opensend Connect solves the exact problem Heap cannot address: identifying anonymous website visitors and providing their actual email addresses. While Heap tracks what users do on your site, Opensend reveals who those users are, enabling direct outreach to browsers who never filled out a form.
The platform operates through a proprietary identity graph built from partnerships with thousands of sites containing millions of registered users who have opted in to receive marketing from partners. When visitors browse your e-commerce store, Opensend's cookieless matching can identify a portion of visitors, achieving 25-35% identification rates for US traffic
Proven Revenue Impact and ROI
Opensend clients consistently report exceptional returns within their first months:
- Decorative Ceiling Tiles increased sales by 19X ROI using Opensend
- Downlite multiplied ROI 33 times using the platform
- Email campaigns see open rates averaging 50-65%, often higher than many retail benchmarks
The transparent pricing structure starts with a $1 two-week trial, then scales from $500/month for sites with 10–50K monthly visitors to $2,000/month for high-traffic properties with 100–300K visitors. Credits roll over monthly, and you only pay for net new leads.
Complete Product Suite Beyond Basic Identification
Opensend offers four integrated products that work together:
Opensend Connect detects high-intent site visitors in real-time and syncs them with your marketing tools for retargeting via email, social, postal, and programmatic ads. The plug-and-play integrations with Shopify, Klaviyo, and other platforms enable quick setup without heavy technical lift
Opensend Reconnect unifies fragmented consumer identities across devices using the proprietary identity graph. This cross-device recognition enables personalized marketing flows and activates more abandonment sequences for returning visitors.
Opensend Revive replaces bounced emails with active addresses for the same users. This automated matching process restores lost connections, prevents churn, and increases customer lifetime value by keeping your list current.
Opensend Personas delivers AI-powered audience segmentation based on real purchase and behavioral data. The platform enriches your CRM data with demographic and lifestyle attributes, then builds ad-ready cohorts that integrate seamlessly with Klaviyo, Google, and Meta.
Why Opensend Outperforms Heap for Visitor Identification
The fundamental difference comes down to purpose. Heap uses unique identifiers to track anonymous users, but cannot reveal their actual identity unless they self-identify through form submissions or logins. Opensend's technology can provide email-level matches without requiring a visitor to fill out a form.
While Heap costs $24,000-60,000+ annually for product analytics alone, Opensend provides visitor identification plus automated email activation for a fraction of that investment—with proven ROI typically within 30 days.
2. PostHog – Open-Source Analytics with Session Replay
PostHog offers an open-source counterpart to Heap’s analytics stack with autocapture functionality and session replay features. The platform targets developer teams who want full data ownership and self-hosting options.
Key differentiators from Heap include:
- Open-source codebase enabling self-hosting and complete data control
- Generous free tier with 1 million events and 5K session recordings monthly
- Built-in session replay and heatmaps without add-on costs
- SQL access for custom queries and analysis
PostHog pricing scales based on usage, with paid plans starting significantly lower than Heap's $3,600/year entry point. However, like Heap, PostHog cannot identify anonymous visitors—it provides behavioral analytics only.
For teams needing both product analytics and visitor identification, combining PostHog's analytics with Opensend's identification capabilities provides comprehensive coverage at lower total cost than Heap alone.
3. Mixpanel – Event-Based Product Analytics
Mixpanel focuses on event-based analytics with pricing starting around $20/month for paid plans. The platform offers deep funnel analysis, cohort tracking, and retention metrics similar to Heap's capabilities.
Strengths compared to Heap:
- More transparent pricing with clear tier structures
- Strong mobile analytics capabilities
- Advanced segmentation and cohort analysis
- 1 million free events monthly on the starter plan
However, Mixpanel shares Heap's core limitation: no anonymous identification. The platform tracks user behavior after identification but cannot reveal who unknown visitors are. Companies seeking visitor identification need a specialized tool like Opensend alongside their analytics platform.
4. Amplitude – User-Based Analytics for Product Teams
Amplitude positions itself as a product analytics platform for understanding user behavior at scale. The platform offers:
- Behavioral cohort analysis for identifying user patterns
- Predictive analytics powered by machine learning
- Robust free tier with 50,000 monthly tracked users
- Strong integrations with marketing and product tools
Pricing starts at $124/month for 5,000 MTUs, making it comparable to Mixpanel for mid-market companies. Enterprise plans offer unlimited events and advanced features.
Like Heap and Mixpanel, Amplitude cannot identify anonymous website visitors. The platform assumes users are already known through authentication or form submission. For e-commerce businesses where most visitors remain anonymous, identifying visitors requires a dedicated identification tool.
5. Dealfront (Leadfeeder) – B2B Company-Level Identification
Dealfront, formed from the merger of Leadfeeder and Echobot, specializes in B2B visitor identification with GDPR-compliant tracking. The platform identifies companies visiting your website rather than individuals.
Key capabilities:
- ~35% company identification rate for B2B traffic
- European data compliance with ISO 27001 and ISO 27701 certifications
- CRM integration for sales team workflows
- Google Analytics compatibility
Pricing starts at €99/month for tracking up to 50 companies, with a free tier identifying 100 companies monthly with 7-day data retention.
The critical limitation: Dealfront provides company names, not individual email addresses. For B2C e-commerce businesses, company-level identification offers minimal value. Opensend's email-level identification delivers actionable contact data for direct-to-consumer marketing.
6. Clearbit Reveal – Enterprise Data Enrichment
Clearbit Reveal provides company-level website visitor identification with deep firmographic data. Following acquisition by HubSpot, the platform now integrates with Breeze Intelligence.
Capabilities include:
- 100+ data attributes per identified company
- ~50% company match rate for website visitors
- Firmographic, technographic and demographic intelligence
- Four-stage verification process for data quality
Pricing through HubSpot's Breeze Intelligence starts at approximately $10 for 1,000 credits, scaling significantly for high-volume usage. The platform targets enterprise B2B companies with complex sales processes.
For e-commerce visitor identification, Clearbit shares the same limitation as other B2B tools: company-level data only. The platform excels at enriching known contacts and identifying business visitors but cannot provide the email addresses that email marketing strategies require.
Understanding the Category Difference
The fundamental insight when evaluating Heap alternatives is recognizing that Heap solves a different problem than visitor identification tools. Heap's autocapture technology tracks events and user behavior—valuable for product optimization—but explicitly does not identify unknown visitors.
When you need to understand what users do: Heap, Mixpanel, Amplitude, and PostHog compete on analytics capabilities, pricing, and ease of use.
When you need to know who users are: Opensend, Dealfront, and similar identification platforms provide contact data for marketing activation.
Many businesses benefit from combining both capabilities: analytics for understanding behavior patterns, and identification for converting anonymous traffic into leads.
Choosing the Right Solution
For e-commerce businesses seeking to capture email addresses from anonymous shoppers, Opensend provides unique email-level identification with proven ROI. The platform's e-commerce specialization and ESP integrations enable automated email flows within minutes of installation.
For B2B companies needing company identification for sales teams, Dealfront or Clearbit Reveal offer firmographic intelligence—though neither provides individual contact information.
For product teams needing behavioral analytics (not visitor identification), PostHog offers the best value with its open-source model, while Mixpanel and Amplitude provide mature alternatives to Heap at more transparent prices.
For comprehensive coverage, combining Opensend's identification with a dedicated analytics platform delivers both capabilities without the complexity and cost of enterprise solutions that attempt to do everything.

Frequently Asked Questions
What is the primary difference between Heap Analytics and visitor identification tools like Opensend?
Heap is a product analytics platform that tracks user behavior through event capture and session replay. It cannot reveal the identity of anonymous visitors—users must self-identify through forms or logins before Heap can associate behavior with a person. Opensend and similar identification tools proactively match anonymous visitors to contact information using identity graphs and partner networks, providing email addresses without requiring visitor action.
How do cookie-less identification methods work?
Cookie-less identification relies on proprietary identity graphs built from networks of partner sites with millions of registered users who have opted in to receive marketing from partners. When a visitor browses your website, the identification platform matches browser signals and behavioral patterns against this network to associate the session with a known identity. This approach maintains effectiveness as third-party cookies phase out and provides compliance with evolving privacy regulations.
Can anonymous website visitor identification tools improve email marketing ROI?
Visitor identification platforms like Opensend directly impact email marketing ROI by expanding your addressable audience beyond form submissions. Identified visitors show open rates of 50-65%—significantly higher than cold outreach—because they've demonstrated interest by browsing your site. This high-intent audience drives conversion rates that justify the identification investment, with many Opensend clients achieving 7-20X ROI within 90 days.
What is an identity graph and why does it matter for cross-device recognition?
An identity graph links multiple identifiers (email addresses, device IDs, browsing patterns) to unified consumer profiles. This enables recognition of the same person across smartphones, tablets, and desktop browsers. For marketing, cross-device recognition means you can identify a returning visitor who previously browsed on mobile and now visits via desktop, activating personalized engagement regardless of device.
What are typical pricing models for visitor identification solutions?
Pricing models vary by vendor and use case. Opensend offers tiered subscriptions from $500-2,000/month based on traffic volume, with per-identity costs of $0.21-0.25. B2B platforms like Dealfront charge €99+/month for company identification with volume-based scaling. Analytics platforms like Heap range from $3,600 to $100,000+ annually depending on session volume and features—though they don't provide identification. Most platforms offer trials or free tiers for evaluation before commitment.
