LeadPost Review: Visitor Identification Features and Insights

LeadPost does something most visitor identification tools don't: it identifies individual people, not just companies. 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: an all-in-one AI GTM Platform built on a B2B data foundation of 500M contacts and 100M companies, 135M+ verified phone numbers, and 200M+ verified business emails. It adds buyer intent signals, conversation intelligence, and AI-powered GTM execution. 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.

Using a combination of deterministic (cookie-based) and probabilistic (IP and device fingerprint) matching, 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.

LeadPost has grown from a B2C retargeting tool into a "visitor intelligence platform" with four core solutions: Lead Identification, Lead Enrichment, Visitor Insights, and Cross-Channel Retargeting. It remains a bootstrapped company with approximately 7 employees, strongest in 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 and 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. A JavaScript pixel placed on your site identifies anonymous visitors using layered matching: deterministic (cookie-based) first, then probabilistic (IP and device fingerprint). Per the FAQ, once a candidate identity surfaces, LeadPost runs third-party verification on addresses and emails before delivery.

B2B data includes name, job title, verified work and personal email, LinkedIn profile, and company details. B2C data includes name, verified email, and home mailing address. LeadPost does not share visitor data across customers, so your competitors cannot see who is visiting your site through the same platform.

Data Enrichment and Visitor Insights: LeadPost fills gaps in existing records and surfaces audience demographics.

Beyond identification, LeadPost offers standalone Data Enrichment for cleaning and completing existing contact records: add mailing addresses to email leads, or append emails to physical addresses. The Visitor Insights module delivers demographic analytics (age range, income, education, homeownership, marital status) on your actual website traffic, useful for validating ICP assumptions and connecting media spend to audience quality through UTM attribution. Data Enrichment starts with 1,000 free monthly credits; Visitor Insights starts with 150 free monthly credits (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 covering email, social ads (Facebook and Instagram), Google display, and USPS direct mail, all from a single dashboard.

Direct mail is the most distinctive feature: automated postcards in 4x6 and 6x9 sizes ship via USPS First-Class at $0.82 and $1.05 per piece with no monthly minimums. Ryan Homes attributed 5 home sales to a 6-week postcard campaign targeting 838 anonymous visitors; VSP found postcard recipients converted 43% higher than a control group. Email retargeting runs through LeadPost's own sending infrastructure (no IP reputation impact) at $0.05 per email; social and display retargeting runs at $0.07 per record with 30-day ad spend included.

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

All Lead Capture plans are month-to-month with no annual commitment.

B2B Lead Capture: Free Trial (14 days, 100 leads, no card) / Standard $199/month (250 leads) / Advanced $349/month (500 leads) / Premium $649/month (1,000 leads)

B2C Lead Capture: Free Trial (14 days, 200 leads, no card) / Standard $249/month (750 leads) / Advanced $499/month (2,000 leads) / Premium $999/month (4,500 leads)

Agencies receive discounts from 32% to 79% based on volume. Nonprofits and startups qualify for 25% off.

What Users Say: LeadPost G2 and Capterra Reviews

LeadPost carries approximately 20 reviews on G2 and 27 on Capterra. Review volume is modest, reflecting the platform's niche audience. The feedback pattern is consistent: reviewers praise accurate contact data, reliable lead delivery, responsive support, and measurable improvements in direct-response conversion rates. Agencies highlight the white-label program and per-client billing.

The friction themes are equally consistent. G2 reviewers note the platform can be "unfriendly to new users" and that phone numbers are absent from real-time identification. Capterra reviewers describe the setup as cumbersome with a learning curve that slows time-to-value. LeadPost does not appear in Gartner or Forrester reports, meaning enterprise buyers will find less independent third-party validation than they might expect.

Where LeadPost Falls Short

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

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

Website Traffic Dependency: LeadPost only works on visitors who come to your website. There is no standalone prospecting database, no third-party intent signals, and no account-based targeting beyond inbound visitors. Teams that need outbound prospecting find LeadPost covers only one piece of the workflow.

No Phone Numbers in Real-Time Identification: LeadPost does not deliver phone numbers for identified visitors. They are available as an unverified enrichment field at 2 credits per record. Sales teams relying on calling cadences will find this limiting.

Interface Learning Curve: G2 and Capterra reviewers consistently describe setup friction and a learning curve that slows time-to-value, particularly for smaller teams without dedicated ops support.

Limited Integration Ecosystem: Native integrations cover Salesforce, HubSpot, Klaviyo, Mailchimp, GoHighLevel, and Zoho CRM. Pipedrive is absent. Additional connections require Zapier or webhooks.
