# RB2B vs Warmly: Which Fits Your Team?

RB2B sends named US visitors to Slack on monthly resolution plans. Warmly adds AI chat, routing and follow-up agents on annual or quarterly contracts. Here is how to choose.

- Choose RB2B for low-cost, person-level Slack alerts on mostly US traffic.
- Choose Warmly when you want identification plus AI chat, routing and follow-up in one contract.
- RB2B names people only in the US; Warmly names people mainly in the US.
- RB2B bills by monthly resolutions; Warmly sells annual or quarterly products with credits and add-ons.
- Warmly agreed to join HubSpot in June 2026, so check integration and renewal terms before signing.

These picks assume a small or mid-size B2B team with meaningful US website traffic that wants named visitors in front of sales quickly. If most of your traffic is European, or you need ad audiences rather than alerts, neither tool is the natural pick. Leadinfo, Albacross or Vector fit those cases better.

## RB2B Vs Warmly At A Glance

RB2B and Warmly both [identify anonymous website visitors](https://growthtribune.com/website-conversion/visitor-identification/), but RB2B sends person-level alerts for US traffic on monthly resolution-based plans, while Warmly bundles identification with AI chat, routing and follow-up agents sold as annual or quarterly products.

| Tool | Pricing model | G2 rating | Who it names | Person-level geography | After a match | Billing basis |
| --- | --- | --- | --- | --- | --- | --- |
| RB2B | Freemium | 4.5/5 (284 reviews) | US people, global companies | US only | Slack or Teams alert | Monthly resolutions |
| Warmly | Paid | 4.5/5 (250 reviews) | Contacts and companies | Strongest on US traffic | Routing, chat, AI agents | Annual or quarterly credits |

The core trade-off is scope against commitment. RB2B is a narrow tool. It tells a seller who is on the site and leaves the next move to that seller or to another tool in the stack. The bill moves with the number of visitors it resolves each month.

Warmly is a wider platform. Identification is its base product, and the higher products add an AI chatbot, live chat, lead routing, automated email follow-up and an autopilot agent that qualifies visitors. The bill is a contract, paid quarterly or annually, with credits and optional add-ons on top.

Neither tool names most visitors. By Warmly's own data, person-level matches run at 5-20% of traffic, and Opensend, a competing vendor, notes that RB2B's headline rate combines person-level and company-level matches. RB2B names people only on US traffic, and Warmly mainly on US traffic. The sections below compare them on the same buyer tasks so you can see which gap matters for your team.

## How This Comparison Scores RB2B And Warmly

This comparison scores RB2B and Warmly on the same six attributes (identity level, person-level geography, activation, cost driver, best fit and limitation) and keeps best-fit calls as labelled judgement.

Each tool is judged on the same four buyer tasks:

- **Identify:** Who the tool names, and on which traffic.
- **Qualify:** How it filters visitors against your ideal customer profile.
- **Route:** Where a match goes (a channel, a CRM, a seller).
- **Follow up:** What happens next, and whether a person or software does it.

> **Note:** Identity level, geography, activation and cost driver describe how each product works. Best fit and limitation are judgement argued from them. Match rates are vendor-reported and vary by traffic, so every pick here depends on your own traffic mix.

Five tools are in scope. RB2B and Warmly are the main comparison. Vector, Leadinfo and Albacross appear as alternatives for the cases neither tool fits, such as European traffic or ad audiences.

## RB2B Vs Warmly Features And What Each Tool Does

RB2B is built to alert sellers about named US visitors in Slack or Microsoft Teams, while Warmly adds AI chat, lead routing and autonomous follow-up agents on top of identification, and [G2 reviewers rate RB2B higher for ease of use and Warmly higher for quality of support](https://www.g2.com/compare/rb2b-vs-warmly-warmly).

G2's side-by-side view also shows reviewers rating the two at parity for value, and small businesses form the largest reviewer group for both (78.0% of Warmly's reviewers and 66.8% of RB2B's).

### RB2B

**RB2B**

RB2B is a website visitor identification tool that works as a notification engine. It matches US visitors to named people, matches companies worldwide and pushes each match into Slack or Microsoft Teams for a seller to act on.

**Verdict:** RB2B is the leaner choice for a team that wants named US visitors in a Slack channel and has a person ready to do the outreach (judgement).

**Identity level:** Contact-level and company-level identification. Starter pushes a LinkedIn profile URL for each named visitor. Pro and Pro+ add business email addresses and email enrichment.

**Person-level geography:** Contact-level identification covers US traffic only. Company-level identification is global on every plan.

**Activation:** Slack and Microsoft Teams delivery on every plan. Pro and Pro+ add integrations with Clay, HubSpot, Salesforce, Zapier, Apollo and webhooks, plus CSV export. Starter has no other integrations.

**Cost driver:** Monthly resolutions, where one resolution is one identified visitor RB2B delivers. Starter includes 300 a month, Pro comes in tiers of 600, 1,250 and 2,500, and Pro+ tiers start at 600.

**Best fit:** Founders, SDR teams and small sales teams selling mainly into the US who already work in Slack or Teams (judgement).

**Limitation:** RB2B has no chat or follow-up agents, so every match still needs a person or another tool to act on it (judgement). Opensend, a competing vendor, also notes in its RB2B review that the headline identification rate combines person-level and company-level matches.

**RB2B pros**

- Slack and Microsoft Teams delivery on every plan
- Cost scales with the visitors it actually resolves
- CRM, Clay and webhook integrations from Pro

**RB2B cons**

- Contact-level identification is US only
- No chat or automated follow-up after a match
- Headline coverage blends people and companies

### Warmly

**Warmly**

Warmly is a go-to-market platform that identifies website visitors and then engages them with AI chat, live chat, automated email and retargeting. It is sold as three products that build on each other, from identification up to an AI inbound autopilot.

**Verdict:** Warmly suits a team that wants software to qualify and engage visitors, not only to name them, and can commit to a quarterly or annual contract (judgement).

**Identity level:** Contacts and companies, with ICP filtering. Warmly runs a waterfall of more than 20 data providers, including Vector, RB2B, Clearbit, ZoomInfo, Apollo, People Data Labs and Demandbase, and requires at least two providers to agree before it shows a match.

**Person-level geography:** Warmly processes global traffic, but its own data shows US traffic matching at two to three times the rate of European or APAC traffic. Customers can restrict person-level identification to US traffic.

**Activation:** The base product covers real-time and Slack alerts, lead routing, CRM sync, sales engagement and webhook integrations, and retargeting through email, LinkedIn or ads. Inbound Chat adds an AI chatbot, "Warm Calling" live chat, Warm Offers, chat metrics and automated email follow-up. AI Inbound Autopilot adds AI goal-setting and qualification, AI-written chat follow-up, automatic email generation and auto-learning chat.

**Cost driver:** Each product starts from 10K credits a month and is billed quarterly or annually. Agent counts rise by product, and add-ons sit on top.

**Best fit:** Funded B2B teams with steady inbound traffic that want identification, chat and follow-up from one vendor (judgement).

**Limitation:** Warmly's ownership is changing. It has agreed to be acquired by HubSpot, and its public promise covers existing contracts and integrations as they stand, not future terms.

**Warmly pros**

- Identification, routing, chat and follow-up in one platform
- Waterfall of 20+ providers with a two-provider agreement rule
- Option to restrict person-level identification to US traffic

**Warmly cons**

- Quarterly or annual commitment rather than monthly usage
- Add-ons raise the cost of the full feature set
- Ownership change pending under the HubSpot agreement

The practical difference is who does the work after a match. With RB2B a seller reads the alert and decides. With Warmly, much of that first engagement can run in software.

## Which Identifies More Visitors, RB2B Or Warmly?

Neither RB2B nor Warmly names most visitors, since Warmly's own production data puts person-level matches at 5-20% of traffic and RB2B advertises 15-20% contact-level coverage on its Starter and Pro plans, rising to 35-45% on Pro+. If the job needs named people, compare the person-level share on your own traffic, not the headline rate.

> **Person-level vs company-level identification:** Person-level identification names the individual behind a visit, usually with a LinkedIn profile or business email. Company-level identification names only the organisation, typically from its network or IP address. Company matches are more common and tell you less about who to contact.

RB2B publishes coverage bands for each plan. Starter and Pro show 15-20% contact-level coverage for US traffic and 15-20% company-level coverage worldwide. Pro+ shows 35-45% for each.

Warmly publishes production averages from more than 1,600 organisations. Company-level matches run at 30-65% of traffic and person-level matches at 5-20%, with an average of about 15%.

**Reading the two ranges side by side:** The figures sit closer than they look. RB2B's Starter and Pro band of 15-20% overlaps the top of Warmly's 5-20% person-level range, and Warmly's average of about 15% sits at the bottom of RB2B's band. Only RB2B's Pro+ band of 35-45% claims clearly more named people, and that figure is RB2B's own.

The scope also differs. RB2B's contact-level band applies to US traffic only. Warmly reports international person-level matches separately, at 3-8%, so its US share sits above its overall average.

**What that means for a few thousand US visitors:** Take a site with 3,000 monthly US visitors. At RB2B's 15-20% band, that is about 450 to 600 named people a month. At Warmly's 5-20% range, it is about 150 to 600. Warmly also puts bot traffic at 10-30% of visits, so check how much of your count is human before applying any rate.

For RB2B, those numbers drive the bill. Each identified visitor RB2B delivers uses one resolution, so 450 to 600 a month is above Starter's allowance of 300 and fits Pro's tiers of 600 or 1,250. For a sales team, 450 to 600 named people a month is roughly 20 to 27 per working day, which is a real follow-up load for one seller (judgement).

Headline rates often blend the two types. Opensend, a competing vendor, makes this point about RB2B and advises comparing how many person-level and company-level resolutions each plan includes. The same question applies to any vendor's figure.

There is a second wrinkle. Warmly's waterfall lists RB2B among its data providers. Part of the RB2B versus Warmly comparison is therefore about orchestration (how many sources a tool combines and how it checks them) rather than raw data.

**Decision rule:** If you need named people, ask each vendor for the person-level share on your own traffic, split by US and non-US visitors. If company-level matches are enough, the gap between the tools narrows.

## Do RB2B And Warmly Work Outside The US?

RB2B names individual visitors only for US traffic and returns company-level matches elsewhere, and Warmly reports that US traffic matches at two to three times the rate of European or APAC traffic. For European visitors the legal context is GDPR, and [GDPR Recital 30 says people can be associated with online identifiers such as IP addresses and cookie identifiers](https://gdpr-info.eu/recitals/no-30/).

**RB2B:** Company-level identification is global on every plan. Contact-level identification is limited to US traffic. A visitor from Berlin or Paris therefore reaches Slack or Teams as a company, with no LinkedIn profile or business email attached.

**Warmly:** Warmly processes global traffic. Its own data puts international company-level matches at 20-40% and international person-level matches at 3-8%, against 30-65% and 5-20% across production traffic. A European visitor is most often a company match, and a named person in only a small share of visits.

**The US-only setting:** Warmly lets customers restrict person-level identification to US traffic. With it switched on, non-US visitors are handled at company level only, which is how RB2B works by default. A team selling into Europe may choose it to keep person-level data to US visitors (judgement).

**Europe and APAC:** Warmly reports the same two-to-three-times gap for European and APAC traffic and gives one international range for both. The figures do not separate the regions, so a team selling into APAC should plan as conservatively as one selling into Europe (judgement).

GDPR sets the context for this traffic. Under Recital 30, an IP address or cookie can be associated with a person and used to identify them. Some EU-focused vendors identify companies rather than people. Leadinfo says it relies on legitimate interest under GDPR Article 6(1)(f), processes only the visitor's IP address without storing it, and treats person-level data such as names, emails or individual IPs as generally needing consent. Albacross also identifies companies rather than individual visitors. That is the vendors' own approach, not a ruling on the law.

In practice, a team with half its traffic in Europe should expect most of that half to arrive as company names in either tool. Budget seller time for account research on those visits, such as finding the right contact at each company, rather than for named follow-up (judgement).

> **Note:** If more than about half of your target traffic comes from outside the US, plan for company-level results from either tool and look at the EU-focused alternatives below.

**Decision rule:** For US-heavy traffic, both tools can name people. For mostly European or APAC traffic, judge both on company-level matches only, and compare them with tools built for that case.

This section is general information, not legal advice.

## What Happens After RB2B Or Warmly Identifies A Visitor?

After a match, RB2B posts the visitor to Slack or Microsoft Teams and, from its Pro plan, syncs to HubSpot, Salesforce, Clay or a webhook, while Warmly can route the visitor, open an AI or live chat, write the follow-up email and retarget the account across email, LinkedIn and ads.

**What each tool does after a match**

| Task | RB2B | Warmly |
| --- | --- | --- |
| Alert | Slack or Teams, every plan | Real-time and Slack alerts |
| Enrich | Business email from Pro | Waterfall of 20+ providers |
| Route to CRM | HubSpot or Salesforce from Pro | Lead routing and CRM sync |
| Engage live visitor | Seller or another tool | AI chatbot or live chat |
| Follow up | Seller or another tool | Automated email follow-up |
| Retarget | Seller or another tool | Email, LinkedIn or ads |

The table shows the split in plain terms. RB2B ends its job when the match reaches a channel or a system. What happens next depends on your team or the rest of your stack (judgement).

That is why RB2B data often feeds [B2B contact databases](https://growthtribune.com/prospecting-data/b2b-databases/) and enrichment tools such as Clay. From Pro, a webhook or Clay integration can pass each match into an enrichment or sequencing workflow, and Zapier, Apollo and CSV export cover the rest.

Warmly keeps more of the workflow in one place. The base product routes leads, syncs to the CRM and retargets accounts. Inbound Chat lets the AI chatbot or a rep on "Warm Calling" live chat talk to the visitor while they are still on the page. AI Inbound Autopilot sets goals for the AI, qualifies visitors and writes the chat and email follow-up.

**Decision rule:** If a seller will follow up on every named visitor, RB2B covers the job. If nobody has time to act on alerts, Warmly's chat and follow-up products do more of that work.

## RB2B Vs Warmly Pricing And What Each One Costs To Run

RB2B's cost rises with traffic because it bills by monthly resolutions and charges 25 to 45 cents for each resolution over the plan, while Warmly's cost rises with scope because it sells annual or quarterly products and adds yearly paid add-ons such as its GTM Signals Package and Warm Experiences.

**RB2B pricing**

| Plan | Price | Billing | Notes |
| --- | --- | --- | --- |
| Free | $0 | per month |  |
| Starter | $79 | per month |  |
| Pro | $149 | per month |  |
| Pro+ | $199 | per month |  |

**What drives RB2B's spend:**

- **Resolutions:** One resolution is one identified visitor delivered. Plans include a monthly allowance (300 on Starter, tiers of 600, 1,250 and 2,500 on Pro).
- **Overage:** Each resolution over the allowance costs 45 cents on Starter and 25 cents on Pro and Pro+.
- **Extra domains:** Additional domains cost $99 a month for up to five domains on Pro and Pro+.
- **High volume:** RB2B's pricing FAQ says Pro+ volumes above 12,500 monthly resolutions are priced with its team.

**Warmly pricing**

| Plan | Price | Billing | Notes |
| --- | --- | --- | --- |
| AI Web-Deanonymization (AI Web-Deanonymization) | $10,000 | per year |  |
| Inbound Chat (Inbound Chat) | $20,000 | per year |  |
| AI Inbound Autopilot (AI Inbound Autopilot) | $30,000 | per year |  |

**What drives Warmly's spend:**

- **Product tier:** AI Web-Deanonymization, Inbound Chat and AI Inbound Autopilot each start from 10K credits a month. Inbound Chat includes one AI Studio agent. Autopilot includes unlimited AI Studio agents plus an Autopilot agent.
- **Billing term:** Warmly invites buyers to pay quarterly to try and switch to annual to save, so annual billing is the cheaper term.
- **Add-ons:** The GTM Signals Package and Warm Experiences are each billed yearly on top of the product. The AI 24/7 Video Chat Agent is priced through sales.

RB2B's low entry point grows with traffic. A site that sends more named US visitors uses up its allowance faster and moves into overage or a higher tier. Warmly's starting figure grows with scope. The full feature set means a higher product and possibly add-ons, all on a contract.

**Decision rule:** If you want a monthly cost that tracks usage and can switch off, RB2B's model fits. If you can budget a quarterly or annual commitment and want one vendor for identification and engagement, price Warmly with every add-on you need included.

## What Does The HubSpot Acquisition Mean For Warmly?

[HubSpot agreed to acquire Warmly in a deal announced on June 30, 2026](https://www.cmswire.com/digital-experience/hubspot-acquires-warmly-to-boost-ai-sales-agents/), and Warmly has told customers that their existing contracts, pricing and integrations stay unchanged, which makes renewal and integration terms the clauses to check before signing a multi-year deal.

Warmly announced that it "has entered into an agreement to be acquired by HubSpot". It told customers that existing contracts, pricing, account teams, product experience and integrations remain unchanged. Its longer-term aim is to connect Warmly's agents with HubSpot's customer platform.

For buyers, the effect depends on the CRM (judgement):

- **HubSpot-centred teams:** The stated aim points toward closer ties between Warmly's agents and the HubSpot platform over time.
- **Teams on another CRM:** The commitment covers today's integrations. Ask what happens to the CRM integration you rely on and to pricing at renewal before you sign.

> **Warning:** Before signing a multi-year Warmly contract, get the renewal terms, price protection and the integrations you depend on written into the contract. Warmly states that existing terms stay unchanged, so ask for the same commitment on renewal in writing.

Larger buyers weighing platforms with account hierarchies and governance can compare [enterprise visitor identification tools](https://growthtribune.com/best-enterprise-visitor-identification-tools/) as well.

## Visitor Identification Platform Comparison With Alternatives To RB2B And Warmly

Teams whose traffic is mainly European usually do better with company-level tools such as Leadinfo, which identifies organisations under GDPR's legitimate-interest basis, or Albacross, which identifies companies and is operated from Stockholm with data stored in Ireland, while US teams that want ad audiences rather than Slack alerts can look at Vector, which syncs identified contacts to LinkedIn, Google, Meta and Reddit.

| Tool | Pricing model | Who it names | Main geography | Best for |
| --- | --- | --- | --- | --- |
| Vector | Paid | US contacts | US only | Paid social audiences |
| Leadinfo | Paid | Companies, decision-makers | 195-country database | European B2B teams |
| Albacross | Paid | Companies | EU focus | EU teams running ads |

These three are not drop-in replacements for each other. Each fits a case where RB2B and Warmly are a weaker match. The full field is in our guide to the [best website visitor identification tools](https://growthtribune.com/best-website-visitor-identification-tools/).

### Vector

**Verdict:** Vector fits a US team that wants identified visitors turned into ad audiences rather than sales alerts (judgement).

**Identity level:** Contact-level matching through its identity graph at about a 10% match rate, by Vector's own figures. IP-to-company matching is only a US fallback, at about 30%. Vector's FAQ also says its tests show 60-75% accuracy against cookied HubSpot contacts.

**Person-level geography:** Geofenced to the US. Vector surfaces US-based contacts only.

**Activation:** Builds contact-level audiences and syncs them to LinkedIn, Google, Meta, Reddit and more. It integrates with Salesforce, HubSpot and Pardot and sends data to Zapier or Clay through webhooks.

**Cost driver:** Plans cap identified visitors and ad audiences each month, with the plan shown in the pricing table below. Vector does not charge overages, so usage pauses at the cap instead.

**Vector pricing**

| Plan | Price | Billing | Notes |
| --- | --- | --- | --- |
| Starter | $36,000 | per year |  |

**Best fit:** US B2B marketing teams that spend on paid social and want to reach known visitors there (judgement).

**Limitation:** Docket, a competitor, describes Vector's HubSpot integration as one-way and limited to a single list, notes no revenue attribution from ad engagement to pipeline, and says Vector dropped sales and outbound use cases in October 2025.

### Leadinfo

**Verdict:** Leadinfo is the stronger fit for a European team that wants to know which companies visit and who to contact there (judgement).

**Identity level:** Identifies the companies behind website visits and reveals decision-maker contact details from its international database, which covers 195 countries. In January 2026 Leadinfo, a team.blue brand, acquired Visitor Queue, a Canada-founded provider serving customers across North America.

**Person-level geography:** Leadinfo identifies companies, not individual visitors, and relies on legitimate interest under GDPR. It says person-level data generally requires consent.

**Activation:** Native integrations with Salesforce, HubSpot, Pipedrive, Microsoft Dynamics, Zendesk Sell, Teamleader, LinkedIn Ads, Slack, Microsoft Teams and Zapier. An Autopilot product targets visiting companies to book meetings.

**Cost driver:** The plan tier, shown in the pricing table below.

**Leadinfo pricing**

| Plan | Price | Billing | Notes |
| --- | --- | --- | --- |
| Starter | $107 | per month |  |
| Scale | $226 | per month |  |
| Pro | $507 | per month |  |

**Best fit:** B2B teams with mostly European traffic that sell to companies and can work from decision-maker contacts rather than named visitors (judgement).

**Limitation:** Leadinfo shows the company, not the person who visited, so a seller still has to pick the right contact at that account (judgement).

### Albacross

**Verdict:** Albacross suits EU teams that want company identification tied to intent scoring and ads (judgement).

**Identity level:** Identifies the companies visiting a site and scores accounts by fit and intent. Albacross calls its EU identification rates "#1", which is its own claim.

**Person-level geography:** Company-level identification. Albacross is operated by Albacross Nordic AB in Stockholm, with data stored on servers in Ireland, according to the European Purpose directory.

**Activation:** Runs display and LinkedIn ads and connects natively with HubSpot, Slack, Microsoft Teams, Pipedrive and Google Analytics, plus Salesforce. Its HubSpot marketplace app shares contacts, companies and deals, offers optional two-way sync and shows 300+ installs.

**Cost driver:** The plan tier, shown in the pricing table below.

**Albacross pricing**

| Plan | Price | Billing | Notes |
| --- | --- | --- | --- |
| Starter | €84 | per month |  |
| Professional | €213 | per month |  |
| Organisation | Custom pricing | per custom |  |

**Best fit:** European marketing and sales teams that want account scoring and ad targeting from the same tool (judgement).

**Limitation:** Contact data comes through a separate Chrome extension rather than the core product, so reaching a person takes an extra step (judgement). The HubSpot app also requires a Starter, Professional or Organisation plan.

## Which Should You Choose, RB2B Or Warmly?

Choose RB2B if your traffic is mostly American and a seller will act on Slack alerts, and choose Warmly if you want software to engage and follow up with visitors, because [6sense's 2025 B2B Buyer Experience Report found the first vendor a buyer contacts wins about 8 of 10 deals](https://6sense.com/?p=607322).

The same report, based on nearly 4,000 B2B buyers, found that the point of first contact moved from 69% to 61% of the buying journey, and that buyers initiated 79% of engagements. Being the first vendor a buyer talks to wins most deals, so the real question is who on your side makes that first contact, a seller acting on an alert or an AI agent (judgement).

Pick by situation:

1. **Small US-heavy team that does its own outreach:** Choose RB2B. Assumes most target traffic is in the US, a seller watches Slack or Teams, and a monthly bill that tracks resolutions suits the budget.
2. **Team that wants identification, live chat and AI follow-up from one vendor:** Choose Warmly. Assumes steady inbound traffic, no spare seller time for every alert, and room for a quarterly or annual contract plus add-ons.
3. **HubSpot-centred team weighing Warmly:** Factor in the HubSpot agreement. Warmly's stated aim is to connect its agents with HubSpot's platform, while today's contracts stay unchanged.
4. **Mostly EU traffic:** Choose Leadinfo or Albacross. Assumes you sell to companies and accept company-level matches, since GDPR treats online identifiers as personal data.
5. **US team buying for paid social audiences:** Choose Vector. Assumes the goal is ad reach to known visitors, not sales alerts.

**Verdict.** RB2B is the better pick for small, US-focused teams that want named visitors in Slack or Teams at a cost that tracks usage, and have a person ready to follow up. Warmly is the better pick for teams that want identification, chat, routing and AI follow-up from one vendor and can commit to a contract. If most traffic is outside the US, neither tool names many people, and a company-level tool fits better. These picks hold for small and mid-size B2B teams; heavier traffic or enterprise governance needs change the maths.

Both tools sit at the meeting point of marketing and [sales and outbound](https://growthtribune.com/sales/), so the right choice also depends on who owns follow-up in your team.

## How To Test RB2B And Warmly Before You Commit

A fair RB2B versus Warmly trial runs both tools on the same pages, counts person-level and company-level matches separately and checks them against known CRM contacts, because Warmly's own data shows demo match rates running three to five times higher than production. Use the checklist below to run that pilot.

- [ ] Install both tools on the same pages for the same period
- [ ] Count person-level and company-level matches separately for each tool
- [ ] Check named matches against contacts already in your CRM, the way Vector benchmarks accuracy against cookied HubSpot contacts
- [ ] Split results by US and non-US traffic
- [ ] Exclude bot traffic, which Warmly puts at 10-30% of visits
- [ ] Discount any demo figure, since Warmly reports demo rates of three to five times production
- [ ] Price the result at your real monthly volume, including RB2B overage and extra domains or Warmly add-ons
- [ ] Note who acted on each match and how fast

Running both at once is practical. Warmly's waterfall already lists RB2B among its providers, so the pilot mostly shows how much Warmly's orchestration, chat and follow-up add on top of a shared data source.

Judge the pilot on the person-level matches your sellers could act on, the share that were real contacts, and the cost per usable match. A large headline number with few named, accurate people is a weak result.

Score each step's result the same way for both tools:

- **Bots first:** Remove the bot share from both counts before anything else, since Warmly puts bots at 10-30% of visits.
- **Named people only:** Compare person-level matches on their own, as Opensend advises separating person-level from company-level resolutions.
- **Accuracy:** Score the share of named matches that agree with contacts already in your CRM. Vector reports 60-75% on the same kind of test against cookied HubSpot contacts.
- **Non-US results:** Set European and APAC results against Warmly's own international person-level range of 3-8%. A pilot far above that range is worth rechecking before you trust it (judgement).

## Frequently Asked Questions

**Can you use RB2B and Warmly together?**

Warmly already uses RB2B as one of more than 20 identity providers in its waterfall and requires at least two providers to agree before it shows a match, so running both tools mostly adds a second view rather than new coverage. Running both makes sense as a short pilot, not a long-term stack.

**Does RB2B give you visitors' email addresses?**

RB2B sends business email addresses on its Pro and Pro+ plans, along with email enrichment and CRM integrations. Starter sends a LinkedIn profile URL for each named US visitor but no email address. Contact-level identification on every plan covers US traffic only, so non-US visitors arrive as companies.

**Why do visitor identification demos show higher match rates than production?**

Warmly reports that demo match rates run three to five times higher than production, so a demo figure overstates what live traffic returns. Warmly also puts bot traffic at 10-30% of website visits and reports US traffic matching at two to three times the rate of other regions. Judge any tool on your own live traffic, not a demo.
