Exact Data vs Prospeo: List Broker or Email Finder - Which Do You Need?
Your marketing manager just forwarded a quote from Exact Data for 10,000 contacts at $1,310. Meanwhile, your SDR team is asking for a self-serve email finder they can use right now. Here's the thing: when you compare Exact Data vs Prospeo, you're really comparing two tools that don't compete at all. One's a list broker for purchased lists. The other's a real-time B2B email finder. Let's sort out which one you actually need.
30-Second Verdict
B2B outbound sales or cold email? Prospeo. 98% email accuracy, self-serve, and native integrations with Smartlead, Instantly, Lemlist, and more.
Consumer direct mail or multi-channel postal campaigns? Exact Data. 315M consumer contacts with postal, phone, and email list options.
Need a CRM and sales engagement in one place? Skip both. Look at Apollo or HubSpot.
Picking the wrong category wastes more money than picking the wrong vendor within a category.
What Is Exact Data?
Exact Data is a mailing list provider - you describe the audience you want, they build a static list, and you pay for the data you buy. Data Axle acquired Exact Data on August 3, 2021, folding it into the Data Axle USA division. The database covers 15M business contacts and 315M consumer contacts, with list hygiene referencing NCOA and CASS on a 30-day cycle.
The model is mostly sales-assisted. You typically work with a rep who tailors the list to your criteria, though Data Axle also promotes Salesgenie as a DIY option powered by the same underlying data.
On Trustpilot, Exact Data holds a 4.2/5 across 245 reviews, with plenty of praise for responsive account managers and list tailoring. The flip side shows up on PissedConsumer, where the rating sits at 1.4/5 across 20 reviews. Recurring complaints include generic or personal email addresses - Gmail, Yahoo, info@ - instead of work emails, along with duplicate records and refund friction.
We've seen this pattern across list brokers. Data quality depends heavily on the segment you're buying. One Trustpilot reviewer noted roughly 95% of the emails they received were personal or generic addresses, not domain-specific work emails. That's a common limitation with purchased lists, not a unique failure of one vendor.
What Is Prospeo?
Prospeo is a self-serve B2B email finder built around real-time verification. The database spans 300M+ professional profiles and 143M+ verified emails, refreshed on a 7-day cycle - compared to the 6-week industry average. Every email runs through a 5-step verification process that includes catch-all handling, spam-trap removal, and honeypot filtering, delivering 98% email accuracy.
No sales call required. Sign up, search with 30+ filters, export verified contacts, and push them into Salesforce, HubSpot, Smartlead, Instantly, Lemlist, Zapier, or your own stack via API. The Chrome extension (40,000+ users) finds verified emails from any website or professional profile in one click.
Static lists decay the moment you buy them. Prospeo's 300M+ profiles refresh every 7 days with 98% email accuracy - no rep, no quote, no $885 minimums. At ~$0.01 per verified email, you get real-time data for a fraction of what list brokers charge.
Ditch the list broker. Find verified emails in seconds.

For 5,000 contacts, Exact Data typically runs around $885 as a one-time list purchase. Prospeo's credit-based model is $99/month for 5,000 credits with 98% accuracy - and you keep prospecting access all month, not just a static file.
Pricing Breakdown
Exact Data uses a pay-per-list model. Minimums start at $90 for postal lists and $180 for email + postal. Example pricing: 2,500 contacts for $510, 5,000 for $885, 10,000 for $1,310. At 50K+ volume, expect $0.05-$0.07 per contact. Validation, setup, and deployment fees can add 30-50% to the sticker price, pushing typical monthly spend to $500-$2,000.
You shouldn't need a sales call to find out how much 5,000 contacts cost. But with list brokers, you often do.
Prospeo publishes everything on its pricing page. Free tier: 75 emails/month. Starter: $39/mo for 1,000 credits. Growth: $99/mo for 5,000 credits. Pro: $199/mo for 20,000 credits. Business: $369/mo for 50,000 credits. That works out to roughly $0.01 per email. No contracts, cancel anytime.
Which Tool Should You Pick?
Look - if your primary channel is email, you have no business buying static lists in 2026. In SaaS, it takes roughly 3,249 cold emails to close a single deal, and every bounced email makes that math worse while damaging your domain reputation. Real-time verification isn't a nice-to-have. It's table stakes. (If you want the mechanics, start with email deliverability and email bounce rate.)
For B2B outbound or cold email sequences, the 98% email accuracy matters because cold email conversion rates hover around 1-5% on average. In our testing, real-time verification catches bounces that static lists miss entirely, and the difference compounds fast when you're sending thousands of emails per week. Native integrations with Smartlead, Instantly, and Lemlist mean you go from search to sequence in minutes. Prospeo also layers in intent data tracking 15,000 topics via Bombora, so you can prioritize prospects who are actively in-market - something no list broker offers.
For consumer direct mail or multi-channel marketing, go with Exact Data. The 315M consumer contacts with postal, phone, and email coverage are built for that workflow. No email finder replaces a list broker for consumer postal campaigns.
B2B on a tight budget? A free tier with 75 emails per month and no credit card required is enough to validate accuracy before spending a dollar. Worth noting: Exact Data advises against using purchased lists on retention platforms like Mailchimp or Constant Contact - a compliance red flag if email is your primary channel. (If you're building a modern outbound stack, see outbound lead generation tools and free lead generation tools.)
The consensus on r/sales and r/coldemail is consistent: in a benchmark test of 2,500 contacts across 8 email finders, no tool exceeded a 77% valid-email rate. That reinforces why verification quality matters more than raw match volume, and why we built our infrastructure around a 5-step verification pipeline rather than bulk scraping.
One Exact Data reviewer found 95% of their emails were Gmail and Yahoo addresses. Prospeo's 5-step verification delivers domain-specific work emails with 98% accuracy - and catches spam traps, honeypots, and catch-alls before they torch your sender reputation.

FAQ
Is Exact Data the same as Data Axle?
Data Axle acquired Exact Data on August 3, 2021, folding it into the Data Axle USA division. Exact Data now runs on Data Axle's database infrastructure, while Data Axle offers broader data solutions and services beyond one-off list purchases.
Can I use Exact Data lists for cold email?
Technically yes, but Exact Data itself advises against loading purchased lists into retention platforms like Mailchimp or Constant Contact. Many ESPs prohibit purchased lists entirely. For cold email, a real-time verified source avoids the deliverability and compliance risks that come with static purchased data.
Does Prospeo offer a free plan?
Yes. The free tier includes 75 email credits and 100 Chrome extension credits per month - no credit card required, no contract. That's enough to test accuracy on real prospects before committing to a paid plan starting at $39/month.
When does a list broker make more sense than an email finder?
Choose a list broker when you need consumer postal addresses, phone-append data for telemarketing, or multi-channel lists combining physical mail with digital outreach. For B2B email-first prospecting, a self-serve finder with real-time verification delivers better accuracy at a fraction of the cost. Mailchimp's guide on list quality is a good primer on why purchased lists create long-term deliverability problems.
