Infofree vs SignalHire: Which Data Tool Fits Your Workflow?
These two tools get compared a lot, but they solve fundamentally different problems. Infofree is a subscription-based list service built for business and consumer list-building - including mailing lists and territory-based prospecting. SignalHire is a credit-based contact finder designed for pulling professional emails and phone numbers via a browser extension, where credits are deducted per contact when at least one email or phone is returned. Comparing them is like comparing a phone book to a search engine.
The 30-second verdict:
- Pick Infofree if you need consumer demographics and local business mailing lists for direct mail or territory-based prospecting.
- Pick SignalHire if you need to quickly pull professional contact details one-by-one while browsing profiles online.
- Skip both if you need verified B2B emails at scale without contracts or credit caps.
What Each Tool Actually Does
Infofree is a list-building service founded by Vin Gupta. It gives you subscription access to databases of 20M businesses and 260M consumers, with filters for geography, SIC codes, income, home value, and more. Think of it as a digital list provider for business and consumer leads with a basic CRM included. It's built for the kind of prospecting where you're pulling thousands of names in a ZIP code, not hunting individual decision-makers.
SignalHire is a contact discovery tool with 800M+ professional profiles. Its core product is a Chrome extension that surfaces emails and phone numbers in 2-5 seconds per profile as you browse. It's positioned squarely at recruiters and sales reps who need contact info fast, one profile at a time. Integrations with tools like JazzHR, JobAdder, Zoho Recruit, and Pipedrive also make it popular for recruiting workflows.
If you're evaluating tools like this for outbound, it helps to map them to your broader sales prospecting techniques and the rest of your stack (CRM, sequencing, enrichment).

Pricing Breakdown
Infofree charges $150/month on annual prepay for the Starter plan, which includes 10,000 exports/year and up to two users. Choose monthly billing and you'll also eat a $99 setup fee. That works out to roughly $0.18 per exported record based on the export cap. If you're doing B2B outbound, the contract friction and setup fee don't make sense for modern sales workflows. Skip it.
If you're trying to sanity-check cost-per-lead across vendors, it’s worth looking at how other tools structure credits and verification in data enrichment services and email list providers.
Infofree charges $0.18/record with contract lock-in. SignalHire burns through credits one profile at a time. Prospeo delivers 300M+ verified B2B contacts at ~$0.01/email with 98% accuracy, 7-day data refresh, and zero contracts.

Data Quality and Accuracy
SignalHire puts its accuracy at 96% through machine learning and real-time verification. Reviews tell a different story, though: outdated or inaccurate contact info shows up as a recurring complaint for both tools. Lead databases typically see meaningful decay within 6-12 months without continuous refresh, and the industry average refresh cycle is about 6 weeks. That gap is where bounce rates quietly destroy your sender reputation.
If bounce rates are already creeping up, you’ll want to tighten both list quality and deliverability basics - start with email bounce rate and email deliverability, then work on improve sender reputation.
We've tested enough data providers to know the gap between claimed and real-world accuracy is where most tools fall apart. Prospeo's 7-day data refresh cycle with 5-step verification, catch-all handling, and spam-trap removal closes that gap in a way slower refreshes simply can't.

What Users Actually Say
Reddit threads comparing these two are thin. Most user feedback lives on G2 and Trustpilot.
Infofree - G2: 2.9/5 (20 reviews), Trustpilot: 2.8/5 (3 reviews)
Reviewers praise the geographic and demographic filtering, and customer service gets positive mentions. The complaints are sharper: data accuracy is a recurring concern, auto-renew contracts catch people off guard, and one Trustpilot reviewer described being "bait and switched." A 2.9 on G2 is rough by any standard.
SignalHire - G2: 3.7/5 (56 reviews), SoftwareSuggest: 4.8/5 (12 reviews)
Ease of use dominates the positive reviews (12 mentions on G2), and the Chrome extension speed is a genuine strength. On the flip side, "expensive for what you get" appears as a common theme, limited credits restrict proper evaluation, and several reviewers flag outdated contact info. The API is another sore spot - webhook-only enrichment with 7-10 second response times frustrates teams trying to build automated workflows.

Most People Comparing These Two Don't Need Either
Here's the uncomfortable truth: if you're searching for this comparison, you're probably doing B2B outbound, and neither tool is built for that. Infofree is a list-building service. SignalHire is a one-at-a-time contact finder with a recruiting bent.
If your real goal is scalable outbound, you’ll get more mileage from tightening your lead generation workflow and choosing the right outbound lead generation tools.
Which Should You Pick?
You need consumer or local business mailing lists. Infofree is built for this. Nothing else here replaces it for direct mail targeting.
You need quick professional contact pulls for recruiting. SignalHire's Chrome extension and ATS integrations make it the right fit. Just know the credits run out fast.
SignalHire's 5 free credits won't tell you anything. Prospeo gives you 75 free emails and 100 Chrome extension credits - enough to run a real test. With 30+ search filters, CRM enrichment, and native integrations with Salesforce, HubSpot, and Instantly, it's built for B2B outbound at scale.
Run your bake-off with data that actually connects you to buyers.
FAQ
How many credits do you get on SignalHire's free plan?
You get 5 credits per month by default, or 10 per month if you install the Chrome extension. No credit card required to start. That's enough to test the interface but nowhere near enough to evaluate data quality across a real campaign.
Is SignalHire good for B2B sales prospecting?
SignalHire works for one-at-a-time contact lookups, but its credit model and recruiting-focused integrations (JazzHR, JobAdder) make it a poor fit for high-volume B2B outbound. Teams running sequences of 500+ prospects per week typically need bulk enrichment, CRM integrations, and intent data - capabilities SignalHire doesn't offer.
