LeadPost Review: Comprehensive Breakdown [2026]

LeadPost does something most visitor identification tools don't: it identifies individual people, not just companies. For marketers who watch 97% of their website traffic leave without a trace, that distinction matters. The platform pairs visitor identification with retargeting across email, social, display, and direct mail, giving small and mid-sized businesses a way to act on traffic they'd otherwise lose.

To write this LeadPost review, we analyzed the platform extensively. We believe it's the right choice if:

• You need to identify individual B2C or B2B visitors, not just the companies they work for

• You want built-in cross-channel retargeting including physical direct mail

• You run a US-focused business with at least 1,000 monthly website visitors

• You're an agency looking for white-label visitor identification with volume discounts

• You want a single system that handles identification and activation in one place

However, LeadPost might not be the best choice if:

• You need global coverage beyond the United States

• You require a full B2B prospecting database independent of your website traffic

• You want buyer intent signals that go beyond website visits

• You need AI-powered account prioritization and automated outreach sequences

• You're building a go-to-market operation across sales, marketing, and RevOps

In this case, consider ZoomInfo: a GTM platform built on a B2B data foundation of 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business emails. It adds buyer intent signals, conversation intelligence, and AI-powered execution through GTM Workspace for sellers and GTM Studio for marketers and RevOps teams. Where LeadPost identifies who visited your site, ZoomInfo identifies who you should be targeting, whether they've visited your site or not.

We've included a detailed look at ZoomInfo later in this review, as the natural next step for teams that need more than visitor identification. If you're ready to explore a broader approach, you can start with ZoomInfo's free trial here.

What is LeadPost?

LeadPost is a visitor identification platform founded in 2020 by CEO Eric Castelli and Chief Sales Officer Tim Kastner in St. Louis, Missouri. The company set out to solve a specific problem: most website visitors leave without filling out a form, and most identification tools only tell you which company visited, not which person.

Source: LeadPost

LeadPost takes a different approach. Using a combination of deterministic (cookie-based) and probabilistic (IP and device fingerprint) matching through multiple data providers, the platform claims to identify up to 40% of anonymous website traffic at the individual level, delivering verified names, email addresses, and mailing addresses for both consumer and business visitors.

The platform has grown from a B2C retargeting tool into what it now calls a "visitor intelligence platform," with four core solutions: Lead Identification, Lead Enrichment, Visitor Insights (demographic analytics), and Cross-Channel Retargeting.

Source: LeadPost

LeadPost remains a bootstrapped company with no outside funding and approximately 7 employees. Its strongest fit is with marketing agencies (through its Agency Partner Program) and B2C businesses in high-ticket verticals like real estate, automotive, and healthcare.

LeadPost Pros & Cons

LeadPost Review: How it Works & Key Features

Website Visitor Identification: LeadPost identifies individual visitors with verified contact data, not just their employers.

LeadPost's core product is its B2B and B2C lead capture system. You place a JavaScript tracking pixel on your website (a Pixel Assistant guides installation), and the platform begins identifying anonymous visitors in real time.

Source: LeadPost

The identification process uses layered matching. Per the FAQ, it "begins with deterministic data providers (cookie-based identification) and also includes probabilistic data providers (IP and fingerprint technologies)." Once a candidate identity surfaces, LeadPost runs third-party verification: addresses are confirmed deliverable and the individual confirmed as a resident; emails are verified as deliverable where available.

For B2C campaigns, the platform delivers verified personal email addresses, first and last names, and verified home mailing addresses. For B2B campaigns, the data is richer: name, job title, verified work and/or personal email, contact phone numbers, LinkedIn profile links, company name and website, and home and business mailing addresses.

Source: LeadPost

Leads are configured through Lead Campaigns using an 8-step wizard that controls audience targeting, scheduling, suppression lists, geographic filters, data priority settings, attribution windows, and budget caps. Leads are delivered by default every five minutes, with intervals configurable up to daily.

Source: LeadPost

The filtering system is thorough. Basic filters cover pages visited, pages excluded, and minimum page views. Advanced filters include browser type, UTM parameters, time on site, scroll and click detection, mobile device detection, and Boolean logic through a Process Macro option. Geographic targeting works by US state or five-digit zip code.

Source: LeadPost

One important detail: LeadPost does not share your visitor data with anyone else. Some competing identity resolution platforms share data across their customer pool, which means your competitors could see who's visiting your site. LeadPost's no-sharing policy avoids that risk.

Data Enrichment: LeadPost fills gaps in existing contact records with verified demographic and contact data.

Beyond identifying website visitors, LeadPost offers a standalone Data Enrichment service for cleaning and completing existing contact records. The system works both ways: you can add verified mailing addresses to email leads for direct mail, or append emails to physical addresses to launch email campaigns.

Source: LeadPost

The enrichment process follows a 7-step self-serve workflow: select input type (email list or name/address list), choose enrichment fields, upload a CSV or Excel file, map columns, review record count, confirm credit estimate, and receive the enriched file via email or dashboard download.

Source: LeadPost

Available enrichment fields vary by input type. From an email list, you can append name and verified address (4 credits), unverified phone number (2 credits), and demographic attributes like age range, marital status, net worth range, household income, homeowner status, and education level (2 credits each).

An Enrichment API also enables single-record enrichment programmatically, allowing enrichment as leads are captured rather than only in batch.

Enrichment pricing starts with a permanent free tier of 1,000 credits per month, scaling to 50,000 credits per month at $799/month on the Premium plan.

Visitor Insights: LeadPost reveals the demographic profile of your anonymous traffic.

LeadPost’s Site Visitor Demographics feature (marketed as "Insights") goes beyond standard web analytics to show who your visitors are in real-world terms.

Source: LeadPost

Where Google Analytics tells you how many people visited and what pages they viewed, LeadPost Insights appends demographic data to identified visitors: age range, gender, marital status, presence of children, net worth range, household income range, homeowner status, education level, occupation, primary language, and automobiles owned.

Source: LeadPost

The Insights dashboard supports filtering by campaign, domain, date range, UTM source, UTM medium, and UTM campaign. Charts support hierarchical drill-down (clicking a state shows city-level data). A GPT-powered data assistant allows natural language queries against the dataset, and a prebuilt analytics report shows how top converters break down by demographics and marketing source.

This feature is useful for validating ideal customer profiles against actual visitor data, and for connecting media spend to audience quality through UTM-linked demographic attribution. Insights requires an active Lead Capture account and starts with 150 free credits per month, with paid plans from $189/month.

Cross-Channel Retargeting: LeadPost activates identified visitors across email, social, display, and physical mail from one dashboard.

Most visitor identification tools stop at data delivery. LeadPost includes a built-in Cross-Channel Retargeting system that lets you reach identified visitors across four channels without needing separate platforms for each.

Source: LeadPost

The four channels are email, social ads (Facebook and Instagram), Google display, and USPS direct mail. Each channel is configured as a separate campaign with shared architecture covering scheduling, audience selection, suppression lists, creative assignment, and budget controls. Multiple creatives trigger A/B testing with evenly split audience allocation.

Direct mail is LeadPost's most distinctive retargeting feature. Automated postcards in 4x6 and 6x9 sizes ship via USPS First-Class at $0.82 and $1.05 per piece respectively.

For high-consideration purchases with long sales cycles, this channel has produced strong results: Ryan Homes ran a 6-week postcard drip to 838 anonymous visitors and attributed 5 home sales directly to the campaign. VSP found postcard recipients converted 43% higher than a control group. An automotive dealership achieved 7 vehicle sales at a $34 cost per acquisition.

Source: LeadPost

Email retargeting runs through LeadPost's own infrastructure with no impact to your IP reputation, so you don't risk your primary sending domain by emailing cold contacts. Pricing is pay-per-send with no monthly minimums: $0.05 per email and $0.07 per record for social/display (ads run 30 days with ad spend included).

For email, LeadPost supports a drip-like sequencing approach: multiple campaigns with staggered send delays simulate multi-touch sequences without a separate marketing automation platform.

Pricing Structure: LeadPost uses volume-tiered flat fees with separate pricing for each product line.

LeadPost structures pricing across five independent product lines. All Lead Capture plans operate month-to-month with no annual commitment.

• Premium: $999/month (up to 4,500 leads)

Data Enrichment: Free (1,000 credits/month) through Premium ($799/month for 50,000 credits). Each enrichment field costs 2-7 credits depending on the data point.

Visitor Insights: Free (150 credits/month) through Premium ($849/month for 4,500 credits). Requires an active Lead Capture account.

Retargeting: Pay-per-use with no monthly fee. Postcards at $0.82-$1.05, emails at $0.05, social/display at $0.07 per record.

All Lead Capture tiers include retargeting capabilities, data enrichment, one-click integrations, and real-time chat support. The Standard plan carries a 48-hour email/ticket response SLA, while Advanced and Premium tiers receive priority support.

Agencies receive discounts from 32% to 79% based on volume, with a single billing plan covering unlimited client accounts and complimentary client trials funded by LeadPost. Special pricing is also available for nonprofits and startups (25% off each).

Where LeadPost Falls Short

LeadPost does individual-level visitor identification well, but several limitations define the platform's boundaries. These reflect deliberate design choices around scope and scale, not product failures.

US-Only Coverage: LeadPost is available only in the US and will only identify US visitors. Any business with international traffic, global operations, or non-US target audiences cannot use the platform. There is no workaround and no timeline for international expansion.

Source: LeadPost

Website Traffic Dependency: LeadPost's identification only works on visitors who come to your website. It cannot help you find or reach prospects who haven't visited yet.

There is no standalone contact database for proactive prospecting, no intent signals from third-party research behavior, and no way to build target account lists independent of your web traffic. If your pipeline strategy requires outbound prospecting or account-based targeting beyond inbound visitors, LeadPost covers only one piece of the workflow.

No Phone Numbers in Real-Time Identification: G2 reviewers note that LeadPost does not provide phone numbers for identified website visitors. For sales teams that rely on calling cadences alongside email outreach, this limits how quickly they can act on captured leads.

Interface Learning Curve: Multiple Capterra reviewers describe setup friction: "the setup can be cumbersome" and "the learning curve is a little tough." G2 reviewers note "the platform can be unfriendly to new users." For a platform targeting SMBs and agencies, this creates an onboarding hurdle that may slow results.

Limited Integration Ecosystem: LeadPost integrates natively with Salesforce, HubSpot, Klaviyo, Mailchimp, GoHighLevel, Zoho CRM, and a handful of others. But Pipedrive and several popular CRMs are missing, requiring Zapier or webhook workarounds. The integration list works for basic marketing stacks but is thin compared to platforms with hundreds of native connectors.

No Analyst Coverage or Broad Market Validation: LeadPost does not appear in Gartner or Forrester reports. With roughly 27 Capterra reviews and 20 G2 reviews, third-party validation is limited. This doesn't reflect product quality, but enterprise buyers conducting due diligence will find less independent verification than they might expect.

These limitations point to a platform built for a specific workflow: identifying US-based website visitors and retargeting them across channels. For teams whose needs extend beyond that into full-cycle prospecting, global coverage, or AI-driven go-to-market execution, a broader platform becomes necessary.

Top LeadPost Alternative for Full Go-to-Market Intelligence: ZoomInfo

ZoomInfo addresses LeadPost's scope limitations by providing the infrastructure for an entire go-to-market operation, not just visitor identification. As a GTM platform, ZoomInfo combines B2B data with an intelligence layer called the GTM Context Graph, accessible through interfaces built for sellers, marketers, and RevOps teams, or through APIs and MCP for any external tool.

Source: ZoomInfo

B2B Data Foundation: ZoomInfo's data covers 500M contacts and 100M companies with verified direct-dial phone numbers and business emails.

LeadPost identifies visitors who come to your website. ZoomInfo gives you access to the buyers you should be targeting whether they've visited your site or not.

The platform spans 500M contacts, 100M companies, 135M+ verified phone numbers, 120M direct-dial phone numbers, and 200M+ verified business email addresses.

Source: ZoomInfo

This data is verified through a multi-source pipeline: automated ML scanning of 28 million site domains daily, third-party partner data covering 95 million businesses, a community of 200,000+ ZoomInfo Lite users who share data back, and an in-house Data Training Lab of 300+ human researchers. First-party data reaches up to 95% accuracy.

Beyond contacts and companies, ZoomInfo tracks buyer intent signals from 210 million IP-to-Organization pairings and 6 trillion+ keyword-to-device pairings sourced monthly, technographic profiles for 30+ million companies, and website visitor identification that resolves anonymous traffic to companies and buying team members.

Source: ZoomInfo

Global coverage extends to 34M+ company profiles outside North America and 200M+ professional profiles outside NA, per ZoomInfo's data page.

This data advantage holds up under external scrutiny. In a Fortune 500 competitive RFP analyzing 25 million contacts across vendors, the independent consultant concluded that "no other competitor came even close."

ZoomInfo holds Leader positions in both the Gartner Magic Quadrant for ABM Platforms and the Forrester Wave for Intent Data Providers, and earned 133 No. 1 rankings on G2 across Sales Intelligence, Buyer Intent, Data Quality, and related categories.

"ZoomInfo gives us the information we need to execute. We don't have to spend our time digging. It's already there, so we can be three steps ahead." (Vensure)

The GTM Context Graph: ZoomInfo fuses B2B data with CRM records, conversation intelligence, and behavioral signals into an intelligence layer that captures why deals move.

Data alone tells you what happened. ZoomInfo's GTM Context Graph, which processes 1.5B+ data points daily, unifies ZoomInfo's third-party intelligence with a customer's own CRM records, conversation transcripts, email interactions, and behavioral signals to capture the context behind outcomes.

A CRM records that a deal moved to stage 4. Conversation intelligence transcribes what the VP of Finance said on the last call. Intent data logs a spike in research activity. The GTM Context Graph connects all three to surface why the deal moved and what the team should do next. This contextual intelligence powers AI-drafted outreach that addresses specific objections and account prioritization based on actual win patterns rather than generic scoring rules.

This intelligence layer exists because of two decades of data unification work, including the integration of Chorus for conversation intelligence, which captures every call, meeting, and email and extracts the signals behind deal movement.

Seismic attributed 39% of active pipeline to opportunities identified or influenced by ZoomInfo signals, with the sales team reporting 54% productivity gains. "That combination of our internal CRM data, external signals, and AI that's given all that context has helped us craft very specific account- and persona-based messages. And people have responded to them right away." (Seismic)

GTM Workspace and GTM Studio: ZoomInfo delivers intelligence through interfaces built for sellers, marketers, and RevOps.

ZoomInfo's intelligence reaches teams through three channels. GTM Workspace is the seller's front-end: an AI-powered workspace where prioritized accounts, AI-drafted outreach, deal intelligence, and CRM updates converge in one place.

Source: ZoomInfo

AI agents handle account research, outreach generation, signal monitoring, and CRM hygiene. Sellers see a complete book-of-business view combining CRM data, ZoomInfo signals, conversation history, and market intelligence.

GTM Studio is the front-end for marketers, RevOps, and GTM engineers. It provides an AI-powered canvas where teams define audiences in natural language, launch multi-channel plays (email, calls, ads, direct mail) triggered by buyer behavior, and measure pipeline impact, all without engineering support. Expansion plays that used to take 3 weeks launch in 30 minutes.

For teams building beyond ZoomInfo's own products, APIs and MCP expose the same intelligence to any custom agent, internal tool, or partner platform.

The MCP server is listed in the Claude directory and supports natural language queries against ZoomInfo's data. All three channels draw from the same GTM Context Graph: the same data, the same intelligence, regardless of where the team works.

"The plug-and-play aspect of the API means I can integrate it into any process and get information at a moment's notice." BDO Canada achieved an 87% reduction in time spent on internal data dashboard updates. (BDO Canada)

Pricing and Access: ZoomInfo offers a permanent free tier and custom-quoted plans for growing teams.

ZoomInfo provides two free entry points. ZoomInfo Lite is a permanent free tier (not a trial) that includes access to ZoomInfo's B2B database with 100M+ verified profiles, 10 monthly export credits, the ReachOut Chrome Extension, mobile app.

Source: ZoomInfo

WebSights Lite (up to 10 website visitor reveals per day), built-in email sending, and HubSpot integration. No credit card required, no time limit.

Source: ZoomInfo

A separate 7-day free trial provides broader access to core platform features including contact and company search, sales intelligence tools, intent signals, and email outreach.

Paid plans are custom-quoted based on seats, credit volume, and features. ZoomInfo organizes its paid tiers into Sales (Professional, Advanced, Enterprise), Marketing (Marketing Demand, ABM Lite, ABM Enterprise), and standalone products (Chorus, Chat). Credits work on a 1-credit-per-export model, and API access is included in all relevant plans.

ZoomInfo costs more than point solutions like LeadPost, reflecting the difference between a visitor identification tool and a full go-to-market platform. The investment pays off in documented outcomes: Snowflake achieved 200% higher conversion rates on ZoomInfo-scored accounts, and GTM Workspace users report boosting pipelines by 23% and booking nearly 60% more meetings per week.

LeadPost or ZoomInfo: Comparison Summary

Final Verdict

The choice between LeadPost and ZoomInfo depends on the scope of your go-to-market needs.

Choose LeadPost if you need a focused tool for identifying anonymous US website visitors and retargeting them across email, social, display, and direct mail. It suits B2C marketers in high-ticket verticals like real estate, automotive, and healthcare, where sending a physical postcard to an anonymous visitor can drive measurable sales. Agencies will find value in the white-label program and volume discounts. If your primary challenge is recovering lost website traffic and you want identification and activation in one platform, LeadPost delivers.

Choose ZoomInfo if your go-to-market strategy extends beyond website visitor recovery into proactive prospecting, account-based marketing, buyer intent monitoring, and AI-powered sales execution. ZoomInfo's data foundation (500M contacts, 100M companies, 135M+ verified phone numbers), the GTM Context Graph's contextual intelligence, and interfaces built for sellers and marketers provide the infrastructure for a complete revenue operation. For teams that need to find buyers before they visit your site, understand why deals move or stall, and act on signals across the full buyer journey, ZoomInfo is built for that work.

Get started with ZoomInfo here.

The core difference is scope. LeadPost answers "who visited my website?" ZoomInfo answers that and extends into "who should I be targeting, what signals indicate they're ready to buy, and what should my team do next?" Both serve their audiences well. Your choice depends on whether visitor identification is your complete need or the starting point of a broader strategy.

LeadPost FAQ

What does LeadPost do?

LeadPost is a website visitor identification platform that identifies anonymous visitors at the individual level and delivers verified contact data including names, email addresses, and mailing addresses. It supports both B2B and B2C identification and includes built-in retargeting across email, social, display, and direct mail. The platform claims to identify up to 40% of anonymous US website traffic using a combination of cookie-based and probabilistic matching methods.

How much does LeadPost cost?

B2B Lead Capture starts at $199/month for up to 250 leads, and B2C Lead Capture starts at $249/month for up to 750 leads. Both include a 14-day free trial with no credit card required. Data Enrichment has a permanent free tier (1,000 credits/month), and cross-channel retargeting is pay-per-use with no monthly fee. ZoomInfo offers a permanent free tier (ZoomInfo Lite) with 10 monthly export credits and access to its B2B database, while paid plans are custom-quoted based on team size and needs.

Does LeadPost work outside the United States?

No. LeadPost is available only in the US and identifies only US-based visitors. International privacy laws such as GDPR and CASL are out of scope. Businesses with global operations or non-US traffic will need a platform with international coverage. ZoomInfo provides global data including 34 million company profiles and 200 million professional profiles outside North America.

What integrations does LeadPost support?

LeadPost integrates natively with Salesforce, HubSpot, Klaviyo, Mailchimp, GoHighLevel, Zoho CRM, Zendesk Sell, GetResponse, AWeber, Campaign Monitor, Constant Contact, Reply.io, and Facebook. Additional connections are available through Zapier and custom webhooks. Pipedrive is a frequently requested but unsupported integration. ZoomInfo's App Marketplace lists over 120 partner integrations, and API access is included in all relevant plans.

Can LeadPost identify individual people, not just companies?

Yes, this is LeadPost's primary differentiator. While most B2B visitor identification tools only match website visitors to company names via IP lookup, LeadPost identifies the specific individual who visited. B2B leads include name, job title, email, LinkedIn profile, and company details. B2C leads include name, verified email, and home mailing address. ZoomInfo also identifies individual contacts through its website visitor tracking (WebSights), and extends this with a searchable database of 500 million contacts for prospecting beyond website visitors.

Does LeadPost provide phone numbers?

LeadPost does not deliver phone numbers through its real-time website visitor identification. Phone numbers are available as an enrichment field through the Data Enrichment product (at 2 credits per record), but these are flagged as unverified. Teams that rely on phone outreach may find this limiting. ZoomInfo's database includes 135 million verified phone numbers and 120 million direct-dial numbers.

Is LeadPost compliant with privacy regulations?

LeadPost operates exclusively in the US, so international privacy laws like GDPR and CASL do not apply. For US regulations, the platform notes that state privacy laws have focused on notification and opt-out requirements, and advises customers to review their own privacy policies. LeadPost does not publicly disclose SOC 2, ISO, or other formal security certifications. ZoomInfo maintains ISO 27001, ISO 27701, SOC 2 Type II, and TRUSTe GDPR/CCPA validations, all renewed annually.

Does LeadPost offer direct mail retargeting?

Yes, direct mail is one of LeadPost's most distinctive capabilities. The platform automates postcard delivery in 4x6 and 6x9 sizes via USPS First-Class at $0.82 and $1.05 per piece, with no monthly minimums. Case studies show strong results in high-ticket verticals: Ryan Homes attributed 5 home sales to a 6-week postcard campaign targeting 838 anonymous visitors, and VSP found postcard recipients converted 43% higher than a control group.
