Captain Verify vs DealSignal: Different Tools, Different Jobs
Captain Verify vs DealSignal isn't a real comparison - it's a category mismatch. One verifies emails and mobile numbers you already have. The other helps you build your prospecting pipeline with verified contact data from scratch. If you're weighing these two, you probably need to decide what you're actually shopping for first.
Email lists decay by roughly 28% every year. That stat matters whether you're cleaning an existing database or building a new one. But the tool you pick depends on which side of that equation you're on.
30-Second Verdict
Use Captain Verify if you already have a contact list and need to scrub it before hitting send. One-time email verification pricing starts at EUR 7 per 1,000 verifications.
Use DealSignal if your SDR team needs net-new contacts with verified emails, direct dials, intent signals, and firmographic data. It starts at $499/mo billed annually on the Starter plan.
Skip both if you want verified prospecting data without a $499/mo commitment or the limitations of a standalone verifier. Prospeo covers 300M+ profiles with 98% email accuracy, intent data across 15,000 topics, and a free tier - no sales call required.

Captain Verify Deep Dive
Captain Verify is a straightforward email verification tool with optional mobile number verification via HLR lookup. Upload a list, get back valid, invalid, risky, or unknown statuses, download the cleaned file. That's it.
What works well:
- Genuinely cheap: EUR 7 for 1,000 verifications, scaling to EUR 650 for 1,000,000 on one-time tiers.
- Subscriptions save an extra 10%, and annual plans include two months free.
- Strong privacy positioning with servers in France, plus ISO 27001 and SOC certification.
- Unknown results get re-credited - you don't pay for inconclusive checks.
Where it falls short:
- One G2 review reports bulk processing taking 70+ minutes for fewer than 1,000 emails. That's painful if you're on a deadline.
- The "unknown" and "risky" categories cause confusion. Capterra reviewers mention uncertainty around how to handle those results, which defeats the purpose of a verification tool.
- No prospecting database, no Chrome extension, no intent data. If you need to find contacts, you need another tool entirely.
Captain Verify cleans lists but can't find contacts. DealSignal finds contacts but costs $499/mo. Prospeo does both - 300M+ profiles, 98% email accuracy, and 125M+ verified mobiles - starting with a free tier. No sales call, no annual contract.

DealSignal Deep Dive
Paying $499/month for DealSignal to verify a list you already have is like buying a pickup truck to carry groceries. But if you need to build that list from scratch, DealSignal is a legitimate ZoomInfo alternative with real teeth. One Capterra reviewer reported reaching "40% more people in our ICP due to their coverage" - that's the kind of result that justifies the price tag.
DealSignal's core differentiator is a dynamic, multi-step verification process combining AI/ML, automation, and human researchers to reverify data just before delivery. Lists can be refreshed within 2-24 hours before campaigns go out, which is a nice touch for teams running time-sensitive outreach.
The platform includes 100+ data points per contact - verified emails, direct dials and mobile phones, mailing addresses, and intent data. Their 97%+ accuracy claim comes with what they call the industry's only 100% accuracy guarantee, where inaccurate contacts get credited back.
The tradeoffs? That verification rigor means turnaround isn't instant. G2 reviews also point to some UI and navigation friction. And Trustpilot sits at 3.8/5 from just 5 reviews - a small but mixed sample that includes at least one scathing critique. We'd want to see a bigger review pool before drawing conclusions there.
Pricing Breakdown
The price gap tells you everything about the category difference.
DealSignal isn't just verifying - it's sourcing contacts, enriching them with firmographics and technographics, and layering intent signals on top. The Starter plan runs $499/mo for 6,000 credits billed annually. Credit mechanics are simple: 1 credit per contact and 4 accounts per credit.
On pure per-contact math, DealSignal's Starter works out to roughly 10-15x more expensive per exported contact than Captain Verify's EUR 7/1,000 verification rate. That comparison isn't entirely fair since DealSignal is also doing sourcing and enrichment, not just cleaning a list - but it illustrates how different these tools are.
Pro and Enterprise tiers require a sales call. Expect Pro in the $1,000-2,500/mo range based on credit volume.
Let's be honest: if your average deal size is under $5K, DealSignal's Starter plan probably costs more than the deals it helps you close. Run the math before signing an annual contract.
When to Pick Each
Pick Captain Verify when:
- You exported 10,000 contacts from a trade show and need to clean them before tomorrow's campaign
- You're running a one-off list scrub and don't want a monthly subscription
- Your verification budget is measured in tens of euros, not hundreds of dollars
Pick DealSignal when:
- Your SDR team needs net-new contacts with verified emails, direct dials, and intent signals
- You're building targeted account lists from scratch with 100+ data points per contact
- You've outgrown manual list-building and want a platform that replaces ZoomInfo at a lower price point
A Third Option Worth Considering
Here's the thing: most teams weighing Captain Verify vs DealSignal don't need a pure verifier or a $499/mo platform. They need something in between.
We've seen this pattern repeatedly - a team signs up for a cheap verifier, realizes they still need to source contacts somewhere else, then cobbles together three tools that don't talk to each other. Or they commit to a big platform and end up using 20% of it. Prospeo sits in that middle ground with 300M+ professional profiles, 98% email accuracy, and 125M+ verified mobile numbers on a 7-day data refresh cycle. It includes intent data tracking 15,000 topics via Bombora, 30+ search filters, and native integrations with Salesforce, HubSpot, Lemlist, and Instantly - all at roughly $0.01 per email.
The free tier gives you 75 verified emails and 100 Chrome extension credits every month. No contract, no sales call, no annual commitment. For growing sales teams that need more than a verifier but aren't ready for a $6K+ annual commitment, it's the fastest way to start prospecting.
Email lists decay 28% per year. Prospeo's 7-day data refresh cycle keeps your contacts current - 6x faster than the industry average. Add intent data across 15,000 topics and 30+ search filters, and you've replaced both a standalone verifier and an enterprise data platform at ~$0.01/email.
Get fresher data than DealSignal at a fraction of the cost.
