Your SDR team just burned a week of sequences on a list that matched every filter and still missed the buying committee. The emails delivered. The titles were right on paper. Nobody replied, because the list answered “who fits the filters” when the real question was “who is in market right now.”
That gap is the cleanest way to understand BookYourData vs LakeB2B. Both sell verified B2B contact data. Both offer email lists, direct dials and enrichment. But they are built for different jobs.
A self-service list platform. You filter, export and pay per credit.
A managed data and growth partner. It builds custom audiences, layers in intent and technographic signals, enriches your CRM and can run the campaign for you.
The right choice depends less on database size and more on how much of the work between “list” and “pipeline” you want to own yourself.
Disclosure: This comparison is published by LakeB2B. We have used only publicly available information from each vendor’s website and independent review platforms, checked on November 3, 2026. Vendor figures are labeled as vendor claims. Pricing and ratings change, so confirm current terms before you buy.
Key takeaways
- BookYourData wins on price transparency: public credit packs start at $99 for 250 contacts, with no subscription.
- LakeB2B wins when the brief is complex: custom audience builds, healthcare and other vertical data, intent and technographic overlays, CRM enrichment and multi-channel campaign execution.
- “97% deliverability” and “95% accuracy” measure different things. Do not compare them as if they were the same number.
- The fair way to decide is a matched sample test on your exact ICP, scored on cost per usable contact, not cost per record.

What is BookYourData?
BookYourData is a self-service B2B contact platform built for speed. You log in, apply filters, review matches and export. An email check runs at the moment of export.
According to its website, the product lineup includes:
- Prospector: database search with 100+ filters, including location, industry, revenue, company size and technology.
- Pre-built lists: ready-made industry and role lists.
- BeSpoke: done-for-you research for audiences the filters cannot produce, with a free 10-row sample.
- Data appending: fills missing fields in an existing contact file.
- Direct Dials: a separate service for direct and mobile numbers.
- Email verification: an 8-step real-time check at export.
The appeal is low friction. You can test it with 10 free credits and buy more without a contract.
What is LakeB2B?
LakeB2B is a B2B data and growth partner, not just a list download. Its homepage promotes 450M+ verified business profiles, a 95% data accuracy commitment and campaign execution tied to business outcomes.
What that covers in practice:
- Custom and ready-made B2B email lists by industry, title, seniority, geography and company size.
- Healthcare data covering physicians, dentists, nurses, hospitals and other healthcare organizations.
- Technology install-base data for teams selling into specific software stacks.
- Intent data and ABM support to prioritize accounts showing buying signals.
- Data enrichment and cleansing with multi-source validation and a confidence marker on each enriched field.
- Campaign execution across email, events, content syndication and social.
The difference is who does the work. With LakeB2B, a team scopes the audience with you, builds it, enriches it and can put it to work in market.
You buy an outcome-ready audience, not a raw export.
Database size and coverage: why the headline number misleads
A bigger database does not mean a bigger usable list for your ICP. BookYourData cites 500M+ profiles and 250M+ contacts. LakeB2B cites 450M+ verified business profiles. Neither number tells you how many current, reachable decision-makers sit inside your exact segment.
A “profile” is not always a unique person with a working business email. Before you compare scale, ask each vendor to define profile, contact, verified contact and company, then count only what matches your brief.
This is where a managed model has an edge. When a LakeB2B team builds the audience with you, the conversation starts from your ICP, not from a filter screen. Gaps in coverage surface during scoping, not after you have spent credits.
Data accuracy: 97% deliverability vs 95% accuracy are different promises
These two numbers measure different things, so one is not “better” than the other.
| Promise | What it measures | What it does not cover |
|---|---|---|
| BookYourData: 97% deliverability guarantee | Share of emails that do not hard bounce; credits replaced if results fall short | Correct person, current title, phone quality, inbox placement or replies |
| LakeB2B: 95% data accuracy commitment | Correctness of the record and its fields | Inbox placement or replies; confirm the measurement window and remedy in your quote |
BookYourData’s guarantee is clear and easy to claim. But it is an email-bounce remedy. An address can accept mail and still belong to someone who changed roles last quarter.
LakeB2B approaches quality at the record level. Its B2B email lists are re-verified every quarter and compiled from multiple sources. Its enrichment service attaches a confidence marker to each enriched field and returns uncertain values as unverified instead of guessing.
For CRM hygiene, knowing which fields you can trust matters more than a single headline percentage.
Whichever vendor you test, ask for the exact definition, denominator, time window and claim process behind the number.
BookYourData pricing vs LakeB2B pricing
BookYourData publishes its prices. LakeB2B prices each engagement to the audience you need. Both are reasonable models, but they price different things.
Selected tiers from BookYourData’s pricing page, checked November 3, 2026 (USD):
| Contacts | Price (USD) | Approx. per contact |
|---|---|---|
| 250 | $99 | $0.40 |
| 1,000 | $299 | $0.30 |
| 10,000 | $999 | $0.10 |
| 100,000 | $5,499 | $0.05 |
Credits do not expire and there is no subscription. BeSpoke custom research starts at $499 for 1,000 records.
LakeB2B is quote-based, with a free sample so you can check the data before committing. A quote reflects your audience complexity, fields, refresh frequency, intent or technographic layers, integration and any campaign scope.
Compare cost per usable contact, not cost per record
A $0.10 credit looks cheap. Then you count the records that miss your ICP, the titles that have changed, the empty phone fields and the hours your team spends cleaning and loading the file. Use one formula for both vendors:
The formula
Cost per usable contact = Data fees + enrichment and verification + integration + internal labor Unique, ICP-matched, usable contactsA higher quote that includes scoping, enrichment and execution can cost less per usable contact than a cheap export your team has to finish.
If you only need a simple one-time list, the self-service model may be all you need.
Intent data, technographics and enrichment
This is where the two providers separate most clearly. BookYourData answers “who matches my filters.” LakeB2B is built to answer “who matches and is worth contacting now.”
Intent data and ABM
BookYourData says supporting signals such as intent, events, funding and job postings can be included, but availability depends on plan and export. For LakeB2B, intent data and ABM sit at the center of the offer. Accounts showing research activity on your topics can be prioritized before your SDRs touch them.
This matters more as teams hand prospecting to AI agents. An AI SDR is only as good as the data it ingests. Feed it a static list and it will write polite emails to the wrong people at scale. Feed it verified contacts with intent and technographic context and it can prioritize accounts that are actually in market.
Technographics
Both vendors offer technology targeting. LakeB2B adds technology install-base data built for vendors selling into a specific stack, which helps when you want to displace a competitor or upsell an integration. Ask each vendor which products it tracks and when each signal was last observed.
Enrichment and CRM hygiene
Both offer data appending. LakeB2B goes further with cleansing, multi-source validation and field-level confidence markers, delivered by file, API or direct CRM connection.
For a team whose real problem is a decaying CRM, ongoing managed enrichment beats a one-time export.
Integrations
BookYourData references CSV and Excel exports plus HubSpot, Salesforce, Pipedrive and Zapier. LakeB2B describes Salesforce and HubSpot connections and API delivery. For both, request a current integration matrix covering sync direction, field mapping and duplicate handling.
Healthcare and vertical data
If you sell into healthcare, LakeB2B deserves a serious look. Its healthcare email lists cover physicians, dentists, nurses, hospitals and other healthcare organizations. A healthcare recruiter reviewing LakeB2B on G2 singles out the depth of its searchable fields (see the reviews below).
BookYourData also lists healthcare professional coverage. In a matched test, check specialty, facility affiliation, current title and phone fields for your target segment.
Customer reviews and ratings
Both vendors are rated highly, but BookYourData has far more reviews on G2. Ratings below were checked on November 3, 2026 and will change.
| Platform | BookYourData | LakeB2B |
|---|---|---|
| 4.9/5 from 362 reviews | 4.8/5 from 7 reviews | |
| 4.9/5 from 103 reviews | No comparable listing found | |
| No current figure captured | 4.5/5 from 17 reviews |
BookYourData reviewers praise ease of use, fast list building and flexible pricing. Common requests include more detail on smaller companies, finer job-title filters and clearer visibility into credit usage.
LakeB2B reviewers most often highlight responsive support, post-sales follow-up, tailored lists for custom requirements and affordable pricing. LakeB2B’s review sample is smaller, so treat ratings as a signal and judge the data itself through a sample.
What LakeB2B customers say on G2
“Lakeb2b has been an essential partner for us in our email campaign process.”
“This level of detail is something I haven’t found with other platforms…”
“Knowledgeable with the industries and request was customized as per our clients.”
“What caught our attention is that lists gave us deliverability of over 95%”
“Customized Requirements and Post-sales followup”
Across these reviews, the same three themes repeat: lists built to the buyer’s exact criteria, fast and responsive people, and pricing reviewers call affordable or reasonable. The one improvement request is specific: Colleen T., who recruits in healthcare, asked for more search fields to help recruiters target exactly the profiles they need.
Excerpts are quoted word for word from public reviews on G2, shortened only where marked, and shown with the reviewer’s G2 display name, role, rating and review date. “G2 invite” means G2 asked the customer to review, with no incentive provided; “organic” means the review was written without any invitation. Individual results, such as the deliverability figure above, reflect one customer’s experience and are not a guarantee.
Compliance for US B2B outreach
No vendor can make your campaign compliant for you. The FTC states that CAN-SPAM has no exception for B2B email. You need accurate headers, honest subject lines, a physical postal address and an opt-out you honor within 10 business days. Buying a contact does not make that person a subscriber.
Phone and SMS outreach carries separate TCPA and Do Not Call obligations, explained in the FCC’s guidance.
On the policy side, LakeB2B publishes a CCPA privacy notice, a data security policy, a Do Not Call compliance policy and a public opt-out. BookYourData’s privacy policy references GDPR and CCPA and describes its data sources.
If your program includes calling, LakeB2B’s dedicated Do Not Call policy is a practical advantage.
For either vendor, request a DPA, source categories and the suppression process in writing.

The Usable Contact Test: a 4-step way to decide
Do not decide on database size or a headline percentage. Run this test with both vendors on the same brief.
- Match. Send both vendors the same ICP: industries, company size, titles, seniority and US geography. Request a sample of 500 to 1,000 records, or the largest each will provide.
- Verify. Check a slice manually against company sites and professional profiles. Run emails through your own verifier and log title accuracy, duplicates, catch-all rates and phone completeness.
- Price. Calculate cost per usable contact with the formula above, including your team’s time to clean, enrich and load.
- Comply. Get the DPA, source categories, suppression process and Do Not Call screening in writing before launch.
The vendor that wins the Usable Contact Test on your ICP is the right vendor, whatever the brochure says.
Questions to ask both vendors
- What percentage of my target records have a verified business email, direct dial and current title?
- When was each field last verified?
- Does your guarantee cover wrong titles, former employees and invalid phones, or only email bounces?
- What is the all-in price for 1,000, 10,000 and 50,000 contacts on this ICP?
- Can I reuse the data across campaigns, and what are the license limits?
- Where does your intent data come from, and how old are the signals?
The bottom line
BookYourData is a strong, transparent tool for buying a list. LakeB2B is built for teams that need that list to become pipeline: scoped to a complex ICP, enriched, layered with intent and technographic signals, kept fresh in the CRM and, when needed, put to work across channels.
If your growth plan depends on reaching the right accounts at the right moment, you need an intelligence layer, not just an export. That is the work LakeB2B does.
