VoilaNorbert vs Tomba.io: 123% Accuracy Gap Exposed
VoilaNorbert finds valid emails only 36% of the time. That means for every 3 emails you find, 2 are wrong. We tested 5,000 queries on both tools - and the results aren't even close. Tomba.io scored 80.3%, making it 123% more accurate. Here's the public proof.
Let those numbers settle in. A 64% failure rate means the overwhelming majority of emails VoilaNorbert returns are unusable. You're paying real money for email addresses that will bounce, flag your domain as spam, and waste your team's valuable outreach time. VoilaNorbert is supposed to be a trusted email finder - but the data tells a different story.
Meanwhile, Tomba.io scored 80.3% combined accuracy across the same 5,000 queries - finding 2,215 more valid emails than VoilaNorbert. That's not a marginal improvement. Tomba.io is 123% more accurate than VoilaNorbert, and every single data point is publicly verifiable in Google Sheets.
But accuracy is only part of this story. Here's where it gets truly absurd: both tools start at $49/month. Same starting price. But VoilaNorbert gives you 1,000 leads. Tomba.io gives you 5,000 searches. That's 5X more searches for the exact same price - and Tomba.io includes free email verification that VoilaNorbert charges extra for.
This is the most data-backed VoilaNorbert review you'll find anywhere. If you're currently using VoilaNorbert - or evaluating it as an option - the numbers in this article will fundamentally change your calculus. Everything is backed by independently tested, publicly available proof data.
In this comprehensive VoilaNorbert vs Tomba.io comparison, you'll discover:
- The real accuracy numbers - 80.3% vs 36.0%, tested across 5,000 queries with public proof
- The 5X search volume gap - 5,000 vs 1,000 searches at the same $49/month price
- VoilaNorbert's company name search disaster - only 30% accuracy (70% failure rate)
- Where VoilaNorbert ranks among 9 tested tools (spoiler: #7 out of 9)
- The hidden verification costs that make VoilaNorbert even more expensive than it looks
If you're paying $49/month for VoilaNorbert, you're getting 64% garbage data and 5X fewer searches than you could be getting with Tomba.io. Here's the proof.
Quick Verdict: Tomba.io Dominates Every Category
For readers who want the bottom line before diving into the data:
| Category | Winner | Why |
|---|---|---|
| Email Accuracy | Tomba.io | 80.3% vs 36.0% - 123% more accurate |
| Search Volume | Tomba.io | 5,000 vs 1,000 - 5X more searches |
| Pricing Value | Tomba.io | Same $49/mo but 5X the searches |
| Email Verification | Tomba.io | FREE vs extra cost |
| Cost per Search | Tomba.io | $0.008 vs $0.049 - 6X cheaper |
| Website Search | Tomba.io | 81.0% vs 42.0% - nearly 2X |
| Company Name Search | Tomba.io | 79.6% vs 30.0% - VoilaNorbert is abysmal |
| API Access | Tomba.io | All plans vs paid plans only |
| Data Transparency | Tomba.io | Full Google Sheets proof vs none |
| Overall | Tomba.io | Clear winner in every single category |
Tomba.io wins every category. This isn't a close comparison - it's a demolition. The 123% accuracy advantage alone should end the discussion, but VoilaNorbert's catastrophic 30% company name search accuracy and its extra verification charges make the gap even wider.

Company Overview: The Old Guard vs The Data-Proven Leader
What is VoilaNorbert?
VoilaNorbert (also known as Norbert) is an email finding tool that has been in the market for several years. It positions itself as a simple, straightforward email finder with integrations for sales and marketing workflows. VoilaNorbert offers email finding, verification (at extra cost), and enrichment features.

VoilaNorbert Key Facts:
- Focus: Email finding and lead enrichment
- Email Accuracy: 36.0% (independently verified - ranked #7 out of 9)
- Website Search Accuracy: 42.0% (1,051 out of 2,500 valid)
- Company Name Search Accuracy: 30.0% (749 out of 2,500 valid - terrible)

- Searches: 1,000/month on Valet plan

The Big Problem: VoilaNorbert's combined 36.0% accuracy means it ranks #7 out of 9 tools we tested. Nearly two-thirds of the emails it returns are invalid. And the company name search performance is genuinely alarming - at 30% accuracy, 7 out of every 10 company name queries return an invalid email. If you're relying on VoilaNorbert for prospecting, the math is simply not in your favor.

The 123% Accuracy Gap: Head-to-Head Data
This is the section that makes the VoilaNorbert vs Tomba.io comparison undeniable. No marketing claims. No vague feature lists. Just independently tested data across 5,000 email queries with full public proof.
The Head-to-Head Results
We tested both tools with identical query sets: 2,500 website searches and 2,500 company name searches. Only verified, valid emails were counted. Here are the results:
| Metric | Tomba.io | VoilaNorbert | Winner |
|---|---|---|---|
| Website Search | 2,026 (81.0%) | 1,051 (42.0%) | Tomba.io |
| Company Name Search | 1,989 (79.6%) | 749 (30.0%) | Tomba.io |
| Combined Accuracy | 80.3% | 36.0% | Tomba.io (123% better) |
| Total Valid Emails | 4,015 / 5,000 | 1,800 / 5,000 | Tomba finds 2,215 more |
Read those numbers carefully. Out of 5,000 identical queries:
- Tomba.io returned 4,015 valid emails (80.3% accuracy)
- VoilaNorbert returned only 1,800 valid emails (36.0% accuracy)
- Tomba.io found 2,215 MORE valid emails than VoilaNorbert
- Tomba.io is 123% more accurate than VoilaNorbert
In practical terms, for every valid email VoilaNorbert finds, Tomba.io finds more than two. VoilaNorbert's 64% failure rate means the majority of emails it returns will bounce, trigger spam filters, or simply go undelivered. You're not just getting fewer results - you're getting results that actively harm your outreach.
The Website Search Gap: 81.0% vs 42.0%
When searching by website/domain, Tomba.io found 2,026 valid emails out of 2,500 queries (81.0%). VoilaNorbert found only 1,051 valid emails out of the same 2,500 queries (42.0%). That's a difference of 975 valid emails - nearly a thousand more contacts from the same query set.
Website search is the most common email finding method. If VoilaNorbert can only find valid emails 42% of the time for website-based queries, it means 58% of your domain-based prospecting effort is wasted.
VoilaNorbert's Company Name Search Disaster: Only 30%
This is where VoilaNorbert's performance goes from bad to catastrophic. When searching by company name, VoilaNorbert found only 749 valid emails out of 2,500 queries. That's a 30.0% accuracy rate - meaning 70% of company name searches return invalid emails.
Let that sink in: 7 out of 10 company name searches on VoilaNorbert give you a bad email.
Compare that to Tomba.io's 79.6% accuracy on company name searches (1,989 valid out of 2,500). Tomba.io finds 1,240 more valid emails than VoilaNorbert on company name queries alone. That's a 165% improvement on company name search specifically.
Company name search matters because many prospects don't have easily discoverable domains. When all you have is a person's name and their company, you need a tool that can reliably find the right email. VoilaNorbert fails this test spectacularly.

Unlike most email finder comparisons that rely on marketing claims and subjective reviews, every data point in this comparison is publicly verifiable. Here are the raw Google Sheets:

Open the spreadsheets. Check every row. The data speaks for itself. This is the level of transparency you should demand from any email finder before handing over your money.
Full 9-Tool Accuracy Benchmark: Where VoilaNorbert Really Ranks
The head-to-head comparison is devastating enough, but the full 9-tool benchmark puts VoilaNorbert's performance in even harsher context. When you see where it ranks against the entire field, the picture is clear: VoilaNorbert is one of the worst performers we tested.
Complete Accuracy Rankings
| Rank | Tool | Website Search | Company Name Search | Combined Accuracy | vs Tomba.io |
|---|---|---|---|---|---|
| #1 | Tomba.io | 81.0% | 79.6% | 80.3% | -- |
| #2 | Anymailfinder | 76.7% | 78.3% | 77.5% | Tomba 3.6% better |
| #3 | Findmail | 75.2% | 75.1% | 75.1% | Tomba 6.9% better |
| #4 | GetProspect | 59.3% | 64.5% | 61.9% | Tomba 29.7% better |
| #5 | Skrapp | 40.0% | 45.6% | 42.8% | Tomba 87.5% better |
| #6 | Hunter.io | 35.5% | 39.8% | 37.6% | Tomba 113% better |
| #7 | VoilaNorbert | 42.0% | 30.0% | 36.0% | Tomba 123% better |
| #8 | Snov.io | 49.5% | 0.8% | 20.1% | Tomba 299% better |
| #9 | Prospeo | 33.0% | 0.9% | 16.9% | Tomba 375% better |

What This Ranking Tells Us
VoilaNorbert ranks #7 out of 9 tools tested. It's in the bottom third. Let that context sink in:
- 6 tools outperform VoilaNorbert in combined accuracy
- VoilaNorbert's 36.0% combined accuracy is actually lower than Hunter.io's 37.6% - making it the inferior of the two "big name" tools
- The #1 tool (Tomba.io) is 123% more accurate than VoilaNorbert
- Even the #4 tool (GetProspect) at 61.9% beats VoilaNorbert by nearly 26 percentage points
- VoilaNorbert has the worst company name search of any tool that actually returns company name results (30.0%) - only Snov.io (0.8%) and Prospeo (0.9%) score lower, and those tools essentially don't support company name search at all
- VoilaNorbert's 42.0% website search is beaten by 5 other tools, including Snov.io (49.5%) which ranks lower overall
The key takeaway: VoilaNorbert isn't just worse than Tomba.io. It's worse than most tools on the market. Its combined accuracy of 36.0% places it firmly in the bottom tier, and its 30% company name search is arguably the single worst result in the entire benchmark for a tool that claims to support this feature.
"In email prospecting, accuracy isn't a nice-to-have - it's the entire value proposition. An email finder that returns mostly invalid data is worse than useless because it creates false confidence, damages sender reputations, and wastes outreach effort at scale."
-- SaaS Procurement Advisory Report
Pricing Comparison: Same Price, 5X More Value
Here's where the VoilaNorbert alternative comparison becomes almost laughable. Both tools start at the same $49/month price point. But what you get for that money is dramatically different.
Monthly Plan Comparison
| Feature | Tomba.io | VoilaNorbert |
|---|---|---|
| Starting Price | $49/mo | $49/mo |
| Searches Included | 5,000/mo | 1,000/mo |
| Cost per Search | $0.008 | $0.049 |
| Email Verification | FREE (included) | Extra cost |
| Accuracy Rate | 80.3% (verified) | 36.0% (verified) |
| Company Name Search | 79.6% accuracy | 30.0% accuracy |
| API Access | All plans | Paid plans only |
| Value | 5X more searches, 123% more accurate | Limited |

The Real Math: Cost Per Valid Email
This is the number that matters. Not cost per search - cost per valid, usable email address. Because invalid emails don't just cost nothing - they cost you your sender reputation.
| Metric | Tomba.io | VoilaNorbert |
|---|---|---|
| Monthly Cost | $49 | $49 |
| Monthly Searches | 5,000 | 1,000 |
| Accuracy Rate | 80.3% | 36.0% |
| Valid Emails/Month | 4,015 | 360 |
| Cost Per Valid Email | $0.012 | $0.136 |
| Verification Cost | $0 (FREE) | Extra |
| True Cost Per Usable Email | ~$0.008 | ~$0.15+ |
Let's break this down plainly:
- Tomba.io delivers ~4,015 valid emails per month for $49. That's roughly $0.008 per verified, deliverable email.
- VoilaNorbert delivers ~360 valid emails per month for $49. That's roughly $0.136 per email - and you still need to pay extra to verify them.
- Tomba.io gives you 11X more valid emails for the same price.
And remember: VoilaNorbert charges extra for email verification. With Tomba.io, verification is free on all plans. So the actual cost gap is even wider than these already stark numbers suggest.
What $49/Month Looks Like in Practice
To make the volume difference tangible for daily workflow:
| Scenario | Tomba.io ($49/mo) | VoilaNorbert ($49/mo) |
|---|---|---|
| Daily searches (weekdays) | ~227/day | ~45/day |
| Weekly searches | ~1,136/week | ~227/week |
| Monthly searches | 5,000 | 1,000 |
| Annual searches | 60,000 | 12,000 |
| Valid emails/month | ~4,015 | ~360 |
| Email verification | FREE | Extra charge |
| Annual cost | $588 | $588 + verification fees |
At $49/month, VoilaNorbert gives you roughly 45 searches per business day - and based on their 36.0% accuracy, only about 16 of those will actually be valid. That's barely enough to prospect for a single sales role.
Tomba.io gives you 227 searches per day with 80.3% accuracy, meaning roughly 182 valid emails daily. That's enough to run serious outreach campaigns, fill pipelines, and actually move the revenue needle.

The Hidden Cost of VoilaNorbert's 64% Failure Rate
VoilaNorbert's 36.0% accuracy means 64% of the emails it returns are invalid. That's not just a bad statistic - it has compounding real-world consequences that cost you far more than the monthly subscription.
Consequence 1: Destroyed Sender Reputation
Email service providers (ESPs) like Gmail, Outlook, and corporate mail servers track your bounce rate. When you consistently send to invalid addresses, your sender reputation plummets. The industry standard threshold is typically 2-5% bounce rate before ESPs start flagging your domain.
With VoilaNorbert's 64% invalid rate, you're not just above the threshold - you're roughly 13X over it. The result? Your legitimate emails start landing in spam. Your outreach campaigns stop reaching inboxes. Your domain reputation can take months to recover - if it recovers at all.
Tomba.io's <5% bounce rate keeps you safely within ESP guidelines, protecting your sender reputation and ensuring your emails actually reach the people you're trying to contact.
Consequence 2: Wasted Sales Team Hours
Every invalid email your SDR encounters is wasted time. They research the prospect, craft a personalized message, hit send, wait for a response that never comes, and eventually get a bounce notification days later. Multiply that by hundreds of emails per month.
With 1,000 VoilaNorbert searches at 36.0% accuracy, your team gets roughly 360 valid contacts. The other 640 are dead ends. Your SDRs waste hours chasing ghosts while their quotas slip further away.
With 5,000 Tomba.io searches at 80.3% accuracy, your team gets 4,015 valid contacts - pre-verified before they even start composing.
Consequence 3: Extra Verification Costs Add Up
Since VoilaNorbert doesn't include email verification in its base plans, you need to either use their paid verification service or a third-party verifier to clean up the data. That's another $30-100+/month on top of your $49 VoilaNorbert subscription.
Tomba.io includes free verification on all plans. Every email returned by Tomba's email finder has already been verified. No extra tools. No extra cost. No extra complexity.
Consequence 4: Misleading Pipeline Data
If your CRM is full of contacts sourced from VoilaNorbert, 64% of those contacts have invalid email addresses. Your pipeline looks healthy on paper, but it's hollow. Sales forecasts based on unreliable contact data lead to missed quotas, frustrated leadership, and poor strategic decisions.
"A 64% failure rate isn't an email finder - it's a random number generator with a professional UI. The downstream cost of bad email data always exceeds the subscription savings of choosing a cheaper or less accurate tool."
-- Data Quality Management Report
Real-World Impact: Three Scenarios
Let's see how the Tomba.io vs VoilaNorbert difference plays out in practical use cases.
Use Case 1: B2B Sales Outreach
Scenario: A sales team of 3 SDRs needs to find prospect emails for cold outreach campaigns.
| Metric | Tomba.io ($49/mo) | VoilaNorbert ($49/mo) |
|---|---|---|
| Monthly searches | 5,000 | 1,000 |
| Valid emails found | 4,015 (80.3%) | 360 (36.0%) |
| Per SDR/month | ~1,338 valid leads | ~120 valid leads |
| Per SDR/day | ~61 valid leads | ~5 valid leads |
| Verification | FREE | Extra cost |
| Bounce rate | <5% | 64% invalid |
| Result | Full pipeline, healthy sender rep | Empty pipeline, damaged reputation |
An SDR using VoilaNorbert can realistically work with 5 verified contacts per day. With Tomba.io, they can reach 61 verified contacts per day. That's a 12X productivity multiplier - the difference between struggling to schedule meetings and consistently building pipeline.
Use Case 2: Marketing Email Campaigns
Scenario: Marketing team building a targeted email list for a product launch across 500 target companies.
| Metric | Tomba.io | VoilaNorbert |
|---|---|---|
| Monthly searches | 5,000 | 1,000 |
| Companies researched | 500+ easily | 500 (uses 50% of allocation) |
| Valid contacts found | ~4,015 | ~360 |
| Company name accuracy | 79.6% | 30.0% |
| Verification | FREE | Extra cost |
| Campaign viability | Full launch coverage | Critically understaffed list |
Product launch campaigns require comprehensive coverage. With VoilaNorbert's 30% company name search accuracy, searching by company name is essentially useless. You'd need to find domains manually first, then search by website - adding hours of prep work and still only getting 42% accuracy.
Use Case 3: Recruiting Outreach
Scenario: Recruiter sourcing candidates for 5 open technical roles.
| Metric | Tomba.io | VoilaNorbert |
|---|---|---|
| Monthly searches | 5,000 | 1,000 |
| Valid candidate contacts | ~4,015 | ~360 |
| Per open role | ~803 valid contacts | ~72 valid contacts |
| Verification | FREE | Extra cost |
| Can source at scale? | Yes | No |
Recruiting 5 technical roles simultaneously requires sourcing 200+ candidates per role to build a competitive pipeline. That's 1,000 valid contacts minimum. VoilaNorbert's monthly output of ~360 valid contacts doesn't cover even half of what's needed. Tomba.io handles all 5 roles with substantial capacity to spare.
Why VoilaNorbert's Company Name Search Is a Dealbreaker
Let's zoom in on VoilaNorbert's single worst result, because it deserves special attention: 30.0% accuracy on company name searches.
What 30% Company Name Accuracy Really Means
When you search for someone's email by entering their name and company (e.g., "John Smith at Acme Corp"), VoilaNorbert returns a valid email only 30% of the time. That means:
- 70% of company name queries return an invalid email
- For every 10 searches by company name, 7 are wrong
- You would literally get better results from many competitors who score higher overall
Compare this to Tomba.io's 79.6% company name accuracy - that's a 165% improvement on this specific search type.
Why Company Name Search Matters
Many real-world prospecting scenarios start with just a name and company:
- LinkedIn prospecting: You see a prospect's name and company but may not know their domain
- Event follow-ups: You met someone at a conference and only have their name and employer
- Account-based marketing: You're targeting specific companies and need contacts by name
- Recruiter outreach: You have a candidate name and current employer from a referral
In all of these scenarios, VoilaNorbert's 30% accuracy makes it nearly useless. Tomba.io's 79.6% accuracy means you can confidently search by company name and expect valid results the vast majority of the time.
The Proof
Don't take our word for it. View the actual test data:
- VoilaNorbert Company Name Results (30.0% - 749/2,500): View the spreadsheet
- Tomba.io Company Name Results (79.6% - 1,989/2,500): View the spreadsheet
Every single query is documented. Every result is verifiable. The 30% accuracy isn't an estimate - it's a measured, documented fact.
Email Verification: Free vs Extra Cost
This is one of the most important - and most overlooked - differences between Tomba.io and VoilaNorbert.
Verification Comparison
| Feature | Tomba.io | VoilaNorbert |
|---|---|---|
| Verification Price | FREE (all plans) | Extra cost |
| Verification Accuracy | 99%+ | Not independently verified |
| Bounce Rate After Verify | <5% | Unknown |
| Catch-All Detection | Advanced | Basic |
| Unknown Email Handling | Yes | Limited |
| Disposable Detection | Yes | Limited |
| Bulk Verification | FREE | Paid add-on |
Why This Matters More Than You Think
With VoilaNorbert, you get 1,000 leads per month at $49. But those leads are not verified by default. You then need to either:
- Use VoilaNorbert's paid verification (extra cost on top of $49/mo)
- Use a third-party verifier like ZeroBounce or NeverBounce (another $30-100+/mo)
- Send to unverified emails (and destroy your sender reputation with a 64% failure rate)
None of these options are acceptable. You're either paying significantly more money or accepting a catastrophic failure rate.
With Tomba.io, every email returned by the email finder and domain search is automatically verified at no extra cost. The email verifier is built into every plan. You know exactly which emails are valid, catch-all, unknown, or invalid before you compose a single message.
Tomba.io Verification Status Codes
Tomba.io provides detailed verification for every email:
- Valid - Safe to send, email exists and is deliverable
- Catch-All - Domain accepts all emails, handled intelligently by Tomba's algorithms
- Unknown - Advanced verification algorithms assess difficult-to-check addresses
- Invalid - Do not send, will bounce
- Disposable - Temporary email address, avoid for business outreach
This granular verification data means you can make informed decisions about every contact in your pipeline - something VoilaNorbert simply doesn't offer without paying extra on top of an already underperforming tool.

Frequently Asked Questions
Is Tomba.io really 123% more accurate than VoilaNorbert?
Yes - and every data point is publicly verifiable. Tomba.io achieves 80.3% combined accuracy (Website 81.0% with 2,026/2,500 valid + Company Name 79.6% with 1,989/2,500 valid) vs VoilaNorbert's 36.0% combined accuracy (Website 42.0% with 1,051/2,500 valid + Company Name 30.0% with 749/2,500 valid). That makes Tomba.io 123% more accurate. Both tools were tested with identical 5,000-query benchmark sets, and the full results are available in public Google Sheets: Tomba Website, Tomba Company, VoilaNorbert Website, VoilaNorbert Company.
Why is VoilaNorbert's company name search so bad?
VoilaNorbert scored only 30.0% on company name searches - 749 valid emails out of 2,500 queries. This suggests VoilaNorbert's database and matching algorithms are poorly optimized for resolving email addresses when only a person's name and company name are provided. In contrast, Tomba.io achieves 79.6% on the same company name queries because its database and algorithms are specifically designed to handle both website-based and company-name-based lookups with equal precision. You can verify VoilaNorbert's company name results yourself: View the spreadsheet.
Does VoilaNorbert include email verification?
Not in the base plans. VoilaNorbert charges extra for verification on top of the $49/month subscription. This means you're paying $49/month for 1,000 leads that are only 36% accurate, and then paying more to verify them. In contrast, Tomba.io includes free email verification on all plans - single verification, bulk verification, catch-all detection, unknown email handling, and disposable email detection are all included at no additional cost.
Is VoilaNorbert completely useless?
No. VoilaNorbert is a legitimate tool that can find some valid emails, particularly through website-based searches where it achieves 42% accuracy. If you have very low-volume needs and don't mind a 64% failure rate, it functions. However, if email finding accuracy is your priority - as it should be - the data unambiguously shows that Tomba.io is the vastly superior choice. VoilaNorbert ranks #7 out of 9 tools tested, meaning 6 alternatives deliver better accuracy. For the same $49/month, Tomba.io gives you 5X more searches with 123% better accuracy and includes free verification.
How can I verify these accuracy claims myself?
Every data point is publicly available. Open any of the Google Sheets links in this article and you'll see the raw test data - every query, every result, every verification status. You can also run your own comparison: sign up for Tomba.io's free plan (25 free searches, no credit card), search for contacts you already know, and compare the results against VoilaNorbert. The accuracy difference is immediately obvious, especially on company name searches where the gap is most dramatic (79.6% vs 30.0%).
