Prospeo vs SignalHire: Which Contact Data Tool Is Worth Your Money?
The Prospeo vs SignalHire decision boils down to one thing: do you want bundled contact data or split billing? SignalHire separates emails and phone numbers into separate paid plans. Want both? That's $110/month on an annual contract - and you're still capped at 5,000 credits under their "unlimited" fair-usage policy.
We're not going to dance around a winner here. Prospeo bundles everything for $49/month with 2,000 credits and no hidden caps.
30-Second Verdict
Prospeo wins on four of five dimensions: pricing, email accuracy (98% vs SignalHire's self-reported 96%), data freshness (7-day refresh vs unspecified), and integrations (native CRM connections vs webhook-based workflows). SignalHire's one genuine edge is shared team credits without per-seat pricing - attractive for large recruiting teams splitting a pool across 10+ users. For sales teams and outbound agencies, Prospeo is the better tool.
Side-by-Side Feature Comparison
| Feature | Prospeo | SignalHire |
|---|---|---|
| Database size | 300M+ verified profiles | 850M+ profiles |
| Email accuracy | 98% (5-step verification) | ~96% (vendor claim) |
| Data refresh | Every 7 days | Not specified |
| Pricing model | Bundled (emails + phones) | Split plans |
| Free tier | 75 emails + 100 Chrome credits | 5 credits/mo (10 with extension) |
| Bulk enrichment | CSV + CRM enrichment | Up to 1,000 per run |
| API | Yes (92% match rate) | Webhook-based |
| CRM integrations | Salesforce, HubSpot, + more | Salesforce, HubSpot, Zoho |
| Email sequences | No (use Lemlist, Instantly, etc.) | Built-in (basic) |
| G2 rating | 4.3/5 | 3.7/5 (56 reviews) |
The 850M vs 300M gap looks dramatic on paper. But database size alone doesn't guarantee deliverability. SignalHire's G2 review themes include outdated info, incomplete data, and even "fraudulent information" as a tagged complaint. Bigger isn't better if half the records bounce. If you're evaluating other databases too, start with our guide to B2B database platforms.
Pricing Breakdown
| Prospeo | SignalHire | |
|---|---|---|
| Free tier | 75 emails + 100 Chrome credits/mo | 5 credits/mo (10 with extension) |
| Emails only | N/A (bundled) | $57/mo annual |
| Emails + Phones | From $49/mo (2,000 credits) | $110/mo annual |
| Cost per unit | ~$0.01 per verified email | ~$0.057 per credit |
| "Unlimited" cap | No cap language | 5,000 credits/mo fair-usage |
Prospeo runs roughly 5-6x cheaper per unit of email lookup. You don't have to decide upfront whether you need emails, phones, or both - everything's bundled into one credit pool.
Here's a nuance that matters for budgeting: SignalHire uses a profile-based credit system where clicking Get Contacts subtracts 1 credit if at least one email or phone is returned, and it can return multiple contacts for that person. Prospeo charges 1 credit per verified email unlocked. In our experience running outbound campaigns, the per-email model is far more predictable when you're forecasting costs at scale (especially if you track cost of lead generation closely).
And about that "unlimited" plan? Read the fine print. Your spending is capped at 5,000 credits per month under their fair-usage policy. That's not unlimited. It's a hard ceiling with better marketing.
SignalHire charges $110/mo for emails and phones - then caps you at 5,000 credits. Prospeo bundles everything at $49/mo with 98% email accuracy, 125M+ verified mobiles, and a 7-day data refresh. No split billing, no fair-usage ceiling.
Stop paying double for data that bounces.
Accuracy: Claims vs Reality
SignalHire's own press release claims 96% accuracy. G2 reviews tell a different story. With a 3.7/5 rating across 56 reviews, recurring complaints include "outdated information," "incomplete data," and "fraudulent information" as tagged themes on the pros and cons page.
One recruiter on r/recruiting tested SignalHire head-to-head against other tools and got an Alaska phone number for a prospect who'd never been to Alaska, plus "a bunch of cell and home numbers from his past." That's the kind of data quality issue that wastes your reps' time and tanks connect rates. If you're trying to reduce bounces systematically, see our breakdown of types of email bounces and the benefits of email verification.
Prospeo's 98% email accuracy comes from a 5-step verification process with catch-all handling, spam-trap removal, and honeypot filtering - all refreshed on a 7-day cycle versus the 6-week industry average. When Snyk rolled out the platform across 50 AEs, their bounce rate dropped from 35-40% to under 5%, and AE-sourced pipeline jumped 180%. (If you're building a repeatable motion, pair this with an outbound sales playbook.)
Integrations and API
Use Prospeo if your stack includes Salesforce, HubSpot, Lemlist, Instantly, Smartlead, Clay, or anything connected via Zapier or Make. The API returns a 92% match rate for enrichment workflows, and native CRM connections work out of the box.
Skip SignalHire if you need real-time API enrichment. One G2 reviewer noted it "just has a webhook" with 7-10 second latency. SignalHire does include built-in email sequences, which is useful if you don't already have a sending tool. But if you're running Lemlist or Instantly - and let's be honest, most outbound teams are - that feature is redundant. If you're comparing senders, use our roundup of best email sequence software.
Who Should Pick Which
Here's the thing: if your deal sizes are above $5k and you're running any kind of outbound motion, you need bundled emails and phones. Paying for them separately in 2026 is like buying a car with the engine sold as an add-on.
Pick SignalHire if you run a recruiting team with 10+ users who need shared credits without per-seat pricing, or you primarily prospect via browser extension across professional profiles, Facebook, GitHub, and company websites. The email-only plan at $57/month is reasonable for light recruiting use. If you're still shopping around, compare it against other options in our AI lead generation tools list.
Pick Prospeo for everything else. 98% email accuracy, 7-day refresh, native CRM connections - at $0.01 per verified email instead of $0.057 per credit. For outbound sales or agency work, the math isn't close. We've seen teams like Stack Optimize build to $1M ARR while maintaining 94%+ deliverability and sub-3% bounce rates across all their clients.
Snyk's 50 AEs cut bounce rates from 35% to under 5% and grew pipeline 180% after switching. Stack Optimize hit $1M ARR with sub-3% bounces across every client. That's what 98% accuracy and 7-day refresh actually deliver.

FAQ
Is SignalHire's "unlimited" plan really unlimited?
No. Their fair-usage policy caps you at 5,000 credits per month - a hard ceiling that resets monthly. If you're running high-volume outbound, you'll hit it within the first two weeks.
Which tool has better phone number accuracy?
Prospeo's verified mobiles deliver a 30% pickup rate across all regions from a database of 125M+ numbers. SignalHire has recurring G2 complaints about outdated numbers and wrong geographies, including numbers from states prospects have never lived in.
Can I try Prospeo for free before committing?
Yes - 75 verified emails and 100 Chrome extension credits per month, no credit card required. That's 15x more free credits than SignalHire's 5/month starter allowance.
How does data freshness compare?
Prospeo refreshes all records on a 7-day cycle, well ahead of the 6-week industry average. SignalHire doesn't publicly specify a refresh cadence, which likely explains the "outdated information" complaints on G2.
