BookYourData Overview
Use this if you want a straightforward list-buying experience with volume discounts and no subscription. BookYourData's 500M+ contact database covers 200+ countries, and every export runs through real-time email verification. The 97% accuracy guarantee is backed by credit-based remediation for bad data - that's a real commitment, not marketing fluff.
Pricing starts with a free 10-credit pack, then $99 for 250 credits ($0.40/contact), scaling down to roughly $0.25/contact at higher volumes. Credits never expire, no contracts.
Skip this if you need intent data, technographic filtering beyond basics, or a platform that integrates natively into your sequencing stack. BookYourData is a list builder, not a prospecting workflow tool.

BookYourData charges $0.40/contact. Thomson Data hides pricing entirely. Prospeo gives you 98% verified emails at ~$0.01 each - 40x cheaper than BookYourData with higher accuracy. Real-time 5-step verification means no 20% bounce rate surprises.
Stop overpaying for static lists that wreck your domain reputation.
Thomson Data Overview
Thomson Data was founded in 2009, is based in Frisco, Texas, and employs roughly 250-500 people. They've carved out a niche in technology install-base targeting - lists of companies running SAP, Salesforce, or similar platforms. They source data from e-zines, newsletters, trade directories, and industry events. Thomson Data also guarantees 80-85% deliverability on mailing lists, a separate and lower bar than their 85-90% accuracy claim.

Their database runs somewhere between 45M and 70M contacts. The exact number depends on which third-party source you check: Datarade says 70M, BookYourData's blog says 60M+, and a separate analysis pegs it at 45M. When a vendor can't keep its database size straight across the ecosystem, that tells you something about internal data governance.
Skip this if you value pricing transparency, independently verified reviews, or guaranteed deliverability above 85%. Thomson Data requires a sales call for every quote. No pricing appears on their G2 page, Datarade, or their own website. That's a red flag in 2026. There are no credible Reddit threads about Thomson Data as a B2B list provider either - search results mostly surface Thomson Reuters discussions instead, which tells you a lot about market awareness.
Data Quality: Where Thomson Data Falls Apart
Thomson Data's own website says "100% accuracy... is a myth" and then guarantees 85-90%. That's honest framing, but an 85-90% accuracy guarantee still leaves meaningful room for wrong or outdated records, which can spike bounces and waste outreach at scale.
The real-world numbers can be worse. One Trustpilot reviewer reported over 20% hard bounces on two separate orders. Thomson Data replaced the contacts - decent customer service - but your domain reputation doesn't get a replacement. A DesignRush review details paying $1,336 for 1,336 companies, finding 1,045 irrelevant and 82 that didn't exist. The refund was refused. And this pattern isn't new: a 2014 Trustpilot review alleged paying for 267 companies and receiving just 37.

Here's the most damning signal: Datarade's unclaimed profile for Thomson Data lists 40% customer retention. That means 60% of buyers don't come back. Compare that to BookYourData's 80 Capterra reviews at 5.0 - a much larger sample of verified buyer feedback painting a completely different picture. BookYourData's 97% guarantee with real-time verification on export is meaningfully better for anyone who cares about protecting their sending infrastructure.
Pricing Transparency
BookYourData publishes everything. Free 10-credit starter pack, $0.40/contact at the entry tier, volume discounts down to ~$0.25/contact. No contracts, credits never expire. You know exactly what you're paying before you buy.

Thomson Data? Complete opacity. Not on G2, not on Datarade, not on their own site. One documented purchase came to exactly $1.00/company ($1,336 for 1,336 companies). Industry-standard list pricing typically runs $0.50-$2.00 per contact depending on targeting specificity. In our experience, vendors that hide pricing are optimizing for their margins, not your budget.
Let's be honest: if your deal sizes sit below five figures, neither of these list-buying models makes sense. You'll burn through credits or overpay per contact when you could get verified emails at a fraction of the cost from a self-serve platform with real-time verification.
Better Alternative: Prospeo
Prospeo solves the core problem - accurate contact data - without the compromises of either option. You get 300M+ profiles with 143M+ verified emails and 125M+ verified mobile numbers. The 30+ search filters include buyer intent powered by Bombora, technographics, job changes, and headcount growth signals. Everything refreshes on a 7-day cycle, and the platform integrates natively with Salesforce, HubSpot, Lemlist, Instantly, and Clay.

Where both BookYourData and Thomson Data sell static lists, Prospeo runs a 5-step verification process with catch-all handling, spam-trap removal, and honeypot filtering - the reason it hits 98% email accuracy instead of hoping for 85-97%. At ~$0.01 per email, it's also dramatically cheaper than either list provider on a per-contact basis. We've seen teams like Snyk cut bounce rates from 35-40% down to under 5% after switching, which is the kind of difference that compounds fast when you're running outbound at scale.


Thomson Data's 40% retention rate and BookYourData's lack of intent data leave gaps in your outbound stack. Prospeo combines 300M+ profiles, 30+ filters including Bombora intent data, and a 7-day refresh cycle - so your lists never go stale like a static CSV export.
Get verified contacts with buyer intent signals, not just another downloaded list.
