Side-by-Side Feature Breakdown

Data Quality & Verification

Every vendor claims 95%+ accuracy. What matters is what happens when you actually hit send.

DealSignal runs a dynamic, multi-step verification process - AI/ML, automated checks, then human researchers - and re-verifies contacts on demand right before delivery. That's fundamentally different from batch verification. Jason H., a Head of Marketing, put it plainly in his G2 review: "Their human verified phone numbers were much more accurate than those from other providers in our testing." The tradeoff is turnaround time. You need to plan around it, which rules out last-minute list pulls.

GetProspect claims 95% accuracy, but an independent Reddit benchmark testing 2,500 contacts across eight email finders found GetProspect hitting just 64.6% valid emails. That's a 30-point gap between the marketing claim and real-world performance. We've seen similar patterns in our own testing - GetProspect lists consistently bounce at higher rates than the headline number suggests.

Here's the thing: GetProspect's 95% accuracy claim is the most misleading stat in this comparison. If you're sending cold email at scale, a 35% invalid rate will torch your domain reputation faster than any spam filter.

Coverage & Ideal ICP

DealSignal's 600M+ records support enrichment and data health workflows common in mid-market and enterprise teams. They can expand coverage for specific industries or regions on demand - a genuine differentiator for teams doing ABM at scale where standard databases run thin. If your ICP is niche (think: VP-level contacts at manufacturing firms in the DACH region), that on-demand research capability is hard to replicate elsewhere.

GetProspect's 200M B2B contacts serve a different motion entirely. SMB teams and agencies building quick lists via the Chrome extension will feel at home. The extension itself is well-regarded - 4.8/5 on the Chrome Web Store with 1,100+ reviews - but one reviewer flagged that "the database coverage is limited compared to larger tools." In some industries and regions, expect gaps.

If you're comparing tools mainly for list building, it’s also worth scanning our breakdown of sales prospecting techniques and the best sales prospecting databases to sanity-check coverage claims.

Pricing Reality

DealSignal starts at $499/mo billed annually, roughly $6,000/year for 6,000 credits. Professional plans run $1,000-$2,500/mo, Enterprise scales to $3,000-$10,000+/mo. No free plan, no self-serve trial. Cost per usable contact on Starter: about $0.08.

GetProspect starts free with 50 valid emails per month. Starter runs $49/mo or $34/mo annual, Growth around $99/mo, and higher tiers go up to $399/mo. Cost per valid email credit on Starter: about $0.049. But factor in that 64.6% validity rate from the benchmark, and your effective cost per usable contact jumps to roughly $0.076.

Let's be honest - if you're just trying to validate whether a tool works for your ICP, being forced into a demo and annual billing is a dealbreaker for most teams. GetProspect wins on accessibility. DealSignal wins on what you get once you're in. (For more context on pricing models across vendors, see our roundup of data enrichment services.)

What Users Actually Say

DealSignal (4.8/5, 95% five-star) earns consistent praise for accuracy and responsive support. The cons cluster around UI navigation and the non-instantaneous turnaround that comes with human verification. Zero one-star reviews is rare for any B2B tool - that says something.

GetProspect (4.0/5, 56% five-star, 9% one-star) gets love for ease of use and the Chrome extension. But the recurring theme across negative reviews is clear: email accuracy is inconsistent, leading to bounces. One reviewer called it "an easy way to get your account shut down" with "poor customer service." In our experience, that tracks. The extension is useful for quick lookups, but we wouldn't trust it for high-volume outbound without running every list through a separate verification step (use an AI email checker or a dedicated verifier from our Bouncer alternatives list).

When to Pick Each Tool

DealSignal is your tool if verification accuracy is non-negotiable, you're enriching CRM data at scale, you want intent data layered into prospecting, and you have enterprise budget with annual commitment flexibility.

GetProspect is your tool if you need a free plan to test before committing, you're building quick prospect lists from professional profiles, you want built-in cold email alongside your data tool, and you're budget-constrained under $100/mo. Just know you'll likely need to verify those emails separately before sending.

A Stronger Alternative to Both

DealSignal's accuracy appeals to a lot of teams, but the demo-only procurement doesn't. GetProspect's accessibility is right for small teams, but the bounce rates are a real problem. Prospeo splits the difference.

One scenario we see constantly: a team signs up for GetProspect, builds a 5,000-contact list, sends a campaign, watches their bounce rate spike to 15-20%, then spends weeks warming a fresh domain. That cycle costs far more than the tool subscription. Weekly data refresh and 98% accuracy aren't just nice numbers - they're what keeps your sending infrastructure alive. (If you're scaling outbound, also watch your email velocity and use email reputation tools to catch issues early.)

FAQ

Is DealSignal worth the price?

Yes, if verification accuracy and CRM data health are your top priorities. The $499/mo Starter plan delivers 6,000 human-verified contacts with on-demand re-verification, but you'll commit annually and go through a demo first. For teams where bad data costs more than the tool itself, it pays for itself quickly.

Is GetProspect safe to use?

Generally, though some users report account restrictions when using the Chrome extension aggressively on professional networking platforms. Start with conservative extraction limits and monitor your account. The one-star reviews specifically flag this risk, so don't ignore it.

What's a good free alternative to both?

Prospeo's free tier includes 75 email credits and 100 Chrome extension credits per month - more generous than GetProspect's 50-email cap. At 98% email accuracy with a 7-day refresh cycle, it outperforms GetProspect on deliverability without requiring DealSignal's enterprise budget. Try it here.
