The short answer
Editorial assessmentLeadPost compared with RB2B
RB2B is the free-tier reference point for US person-level B2B identification, pushing names into Slack. LeadPost costs $249 a month minimum but resolves consumers rather than only business visitors, adds postal addresses, and executes retargeting rather than only notifying. If your visitors are B2B buyers and you want a name in Slack, RB2B is nearly free. If your visitors are consumers, RB2B has nothing for you and LeadPost is the correct category.
Choose LeadPost if
Consumer businesses in high-ticket verticals such as real estate, automotive, and healthcare where a named individual with a postal address is worth pursuing, marketing agencies running identification and retargeting for a portfolio of B2C clients, and ecommerce brands that want to recover anonymous browsers into Klaviyo without waiting for a form fill.
Choose RB2B if
United States focused small businesses and startups with meaningful inbound traffic who want to know which specific human is evaluating them, teams that already live in Slack and will act on an alert within minutes, and founders who want to run a warm outbound motion off their own site without buying an enterprise ABM platform.

| Best for | Consumer businesses in high-ticket verticals such as real estate, automotive, and healthcare where a named individual with a postal address is worth pursuing, marketing agencies running identification and retargeting for a portfolio of B2C clients, and ecommerce brands that want to recover anonymous browsers into Klaviyo without waiting for a form fill. | United States focused small businesses and startups with meaningful inbound traffic who want to know which specific human is evaluating them, teams that already live in Slack and will act on an alert within minutes, and founders who want to run a warm outbound motion off their own site without buying an enterprise ABM platform. |
| Setup time | Minutes. One line of code, no forms, no cookie configuration, and no per-platform integration. Connecting Klaviyo, HubSpot, or an FTP delivery adds perhaps another half hour. | Under thirty minutes. Paste the pixel through a tag manager, connect Slack, and identifications start arriving with the next wave of traffic. The genuinely useful work is the filtering configuration afterwards. |
| Learning curve | Low on identification, moderate on retargeting. The identification side needs no configuration, but running four channels well, particularly direct mail with its production lead times and per-piece costs, is a real marketing discipline rather than a toggle. | Very low as software, moderate as a process. The tool is a feed; the skill is deciding what to do with a name and how quickly. Teams that treat identifications as a to-do list rather than a curiosity feed get value, and the rest churn. |

Strengths and limitations
LeadPost
Strengths
- The only tool in this category that returns a verified postal address and can execute USPS direct mail from the same dashboard, which opens a channel no company-level competitor can reach.
- Genuinely cross-channel: email, Facebook and Instagram, Google display, and physical mail all managed from one interface rather than exported to four platforms.
- Every feature on every tier, with the three published plans differing only in lead volume and support response.
- An unusually long and explicitly named integration list for a seven-person company, including Klaviyo, HubSpot, Salesforce, Mailchimp, Zoho, Reply.io, webhooks, Zapier, and automated FTP.
Limitations
- The ethical position is the most exposed in this category. Posting physical mail to the home address of someone who browsed anonymously is a step beyond what most buyers have thought through, and the recipient consented to a data partner rather than to you.
- GDPR compliance is asserted rather than documented. There is no published legal basis, no data residency statement, and no certification, and the model is fundamentally a US consumer identity product.
- Opt-out is claimed but the workflow is not published, nor is the data partner list, nor any data broker registrations.
- The up-to-40-percent match rate is a vendor claim with no stated denominator and no methodology, unlike competitors such as Knock2 that at least define what traffic they are measuring.
RB2B
Strengths
- Person-level identification with a name and a LinkedIn profile, which is categorically more actionable than the company-level identification every other tool at this price provides.
- Real-time Slack delivery, often while the visitor is still on the site, which turns a signal into a same-hour conversation rather than a weekly report.
- Pricing that a small business can actually buy: free to start, $79 to $199 a month, month to month, no implementation fee, and published overage rates.
- Bootstrapped and profitable with no investor timeline forcing a move upmarket, which is a genuine stability argument in a category where funded competitors get acquired and shut down.
Limitations
- Person-level identification is United States only, with IP ringfencing preventing overseas resolution, which rules the product out for most European and Asia-Pacific focused businesses.
- Match rates are a share of traffic, not all of it, and that share varies enormously by audience, so the same plan delivers wildly different value to two different companies.
- The product ends at the identification. There is no intent scoring model, no account research, no sequencing, and no sending; you supply everything downstream.
- It generates a stream of false positives by construction: job seekers, competitors, existing customers, and analysts all trigger identifications and consume resolutions.
Pricing compared
LeadPost
Flat monthly subscription metered on identified leads per month, with three published self-serve tiers differing in lead allowance and support level rather than in features.
- Standard$249
- Advanced$499
- Premium$999
Judged against B2B company-level tools LeadPost looks expensive, but that comparison is meaningless: those tools return a company name and LeadPost returns a household. Judged against what it replaces, which is a purchased consumer mailing list plus a separate email platform plus a separate audience-push tool, 22 to 33 cents per verified identified person with four retargeting channels in one dashboard is reasonable. The pricing curve is unusually flat, so there is little economic reward for scaling up, and the every-feature-on-every-tier structure means a small operator gets the whole platform at $249. The value hinges on your vertical: in real estate, automotive, healthcare, and high-ticket ecommerce, where a single conversion is worth thousands, the maths works easily. In low-margin ecommerce or B2B SaaS it does not.
RB2B
Self-serve monthly subscription metered by identification resolutions, with published overage rates and a per-domain add-on.
- Free$0
- Starter$79
- Pro$149
- Pro Plus$199
For a United States focused business, RB2B is the highest-leverage $149 in this category. Person-level identification with a business email address, pushed to Slack in real time, is a capability that ABM platforms charge tens of thousands a year for, and RB2B sells it month to month with a published overage rate. The value depends entirely on two variables you can measure in a week: how much of your traffic is American, and what share of it resolves. If both numbers are good, nothing else here competes on capability per dollar. If your traffic is European, the product degrades to company-level identification and cheaper alternatives do that job just as well.
Editorial verdict on each
LeadPost
LeadPost is the consumer answer in a category built almost entirely for B2B, and on its own terms it is well made: person-level resolution with a verified postal address, four retargeting channels including physical mail in one dashboard, an honest published traffic minimum, a long named integration list, and every feature available at the $249 entry price. For real estate, automotive, healthcare, and high-ticket ecommerce, where a single conversion is worth thousands and direct mail still converts, the economics work easily at 22 to 33 cents per identified person. For B2B software it is the wrong shape, and for anyone with European visitors it is the wrong jurisdiction. The thing to settle before buying is not the pricing but the premise: the person whose home address arrives in your dashboard consented to one of LeadPost's data partners, not to you, and the vendor publishes neither the partner list nor the opt-out workflow. If posting a letter to that household still feels right after thinking it through, this is a capable tool. If it does not, that instinct is worth more than the match rate.

MomentumRB2B is the cheapest way to find out which specific human is on your website, and for a United States focused small business that is a genuinely unfair advantage for $149 a month. The pixel takes minutes, the alert lands in Slack while the person is still reading, and the pricing is month to month with published overage instead of an annual ABM contract. Two things decide whether it works for you, and both are measurable in a week: how American your traffic is, and how much of it resolves. Run the free tier, then the seven-day Pro trial, and look at the actual match rate before you commit. If your buyers are European, walk away and buy a company-level tool built for that market. And whatever your geography, understand that RB2B hands you a name and stops; the scoring, the judgement, and the message are still your job.
