Datanyze vs Voila Norbert: Which One Fits Your Workflow?
Choosing between Datanyze and Voila Norbert means deciding between a browser-based contact revealer and an email finder with a sequences engine bolted on. They look similar from the outside. They solve different jobs.
30-Second Verdict
- Pick Datanyze if you're an SDR who lives in a browser and needs direct dials for cold calling. Its 48M direct dial numbers are the main draw.
- Pick Voila Norbert if your motion is email-first outbound and you want finding, verification, and sequences under one roof.

What Each Tool Actually Does
Datanyze is a Chrome extension that reveals emails and direct dials as you browse professional profiles and company websites. Click the extension, spend a credit, get the data. It also surfaces technographic data - what tech stack a company runs - which makes it particularly useful for SaaS sales teams targeting accounts based on specific tools. But the product stops there. No sequences, no API, and the workflow is essentially browser extension plus CSV export.
Voila Norbert takes a different approach. Give it a name and domain, and it finds the email with an advertised success rate of up to 98%. From there you can verify, enrich with company and role data, or drop the contact into a built-in sequence. The API supports prospecting, verification, and enrichment, making it automatable for teams running bulk workflows. That's a meaningful advantage if you're building anything beyond manual one-at-a-time prospecting.
Datanyze burns credits on failed reveals. Voila Norbert doesn't publish database size. Prospeo covers 300M+ profiles, 143M+ verified emails, and 125M+ mobile numbers - all refreshed every 7 days with 98% email accuracy.

Pricing Breakdown
Datanyze keeps it simple:
- Nyze Lite - $0 with 10 credits/month for 90 days.
- Nyze Pro 1 - $29/month for 80 credits/month ($21/month billed yearly).
- Nyze Pro 2 - $55/month for 160 credits/month ($39/month billed yearly).
One G2 reviewer called it "best bang for the buck" at 80 contact reveals for $29/mo. Fair enough for light prospecting.
Voila Norbert's pricing is modular:
- Prospecting plans range from $49/mo for 1,000 leads to $499/mo for 50,000 leads. Annual billing drops the Valet tier to $39/mo. All prospecting plans include unlimited team members and credit rollover.
- Verification runs pay-as-you-go at $0.003/email with a $2 minimum per batch.
- Enrichment starts at $0.04/email up to 2k, drops to $0.02/email up to 50k, then $0.015/email at higher volume.
- Sequences is a separate product priced per user: Starter at $19/user/mo caps at 500 emails/month - enough for a solo SDR but tight for a team.
Let's do the real math. An SDR needing 1,000 verified emails per month pays about $52/mo with Voila Norbert ($49 Prospecting + roughly $3 Verify). Datanyze at $55/mo gets you 160 reveals. For volume email work, Voila Norbert wins on unit economics by a wide margin - especially if you're running a structured B2B sales cadence.
Watch-Outs and User Sentiment
Datanyze is fast for one-off prospecting, and its direct dial coverage is the standout feature. But Trustpilot sits at 1.9/5, with support complaints, billing issues, and data accuracy concerns dominating the reviews. The credit-per-reveal model also burns through allocations faster than most SDRs expect - especially when a chunk of those reveals come back empty. If you're building a calling-heavy motion, it helps to benchmark against a dedicated guide on how to get data for cold calling.
Voila Norbert only charges for successful finds, which is a fairer credit model that G2 reviewers consistently praise alongside accuracy and ease of use. The weak spots: UX and spintax features need work per user feedback, and lower tiers can feel restrictive if you're prospecting aggressively. If verification is a core requirement, compare approaches in our email validity check breakdown.
Here's the thing: if your deal sizes sit below $15k and you're sending more than 500 emails a month, neither tool gives you the data quality or volume you need. You'll outgrow both fast. We've seen this pattern repeatedly with teams that start on a lightweight tool and hit a wall within two quarters.

When Data Freshness Is the Real Problem
Both tools share a core weakness: neither publishes a data refresh cycle. In our experience, that silence usually means the data sits for weeks or months before getting updated, and your bounce rates tell the story before anyone admits it. This is where data hygiene tools and a defined data verification process stop being “nice to have.”
Prospeo refreshes every 7 days, covers 143M+ verified emails and 125M+ verified mobile numbers, and runs a 5-step verification process with catch-all handling and spam-trap removal. The free tier gives you 75 emails and 100 Chrome extension credits per month with no contract - enough to pressure-test the data before you commit anything. If you're troubleshooting bounces, our guide to an email bounce back checker can help you isolate the root cause.
Neither Datanyze nor Voila Norbert publishes a data refresh cycle - and your bounce rates pay the price. Prospeo refreshes every 7 days, runs 5-step verification with spam-trap removal, and costs roughly $0.01 per email. No contracts, no sales calls.

FAQ
Does Datanyze charge for failed lookups?
Yes - one credit per reveal regardless of result. Voila Norbert only charges when an email is actually found, making it far more efficient at volume.
Can Voila Norbert find phone numbers?
Voila Norbert is primarily email-focused across finding, verification, enrichment, and sequences. For direct dials, Datanyze's 48M direct dial numbers or a dedicated mobile data provider like Prospeo with 125M+ verified mobiles and a 30% pickup rate is a better fit.
What if I need both email finding and real-time verification?
Prospeo combines email finding, mobile finding, and real-time verification in one platform with 98% email accuracy. The free tier - 75 emails plus 100 extension credits per month - lets you test before committing.
