Tomba vs Voila Norbert
An independent, review-free comparison compiled by the SaaSTracker editorial team. Both products are profiled in full, and neither can pay for placement here.
The short answer
Both sides assessedTomba compared with Voila Norbert
Both are veteran-feeling web-crawl email finders that charge only for successful finds and roll credits over. Norbert is far more expensive per unit, 49 dollars for 1,000 leads against Tomba's 8.90, but includes unlimited team members, a bundled sequencer product, and separately priced verification at 0.003 dollars an email that undercuts Tomba's bundled model at very large list sizes. Take Norbert if you want unlimited seats and cheap standalone verification; take Tomba if per-email cost and API depth are what you are buying.
Voila Norbert compared with Tomba
Tomba is five times cheaper per found address, at 8.90 dollars per thousand credits against Norbert's 49 per thousand leads, and ships ten SDKs across fourteen endpoints. Norbert answers with unlimited seats, credit rollover, twelve years of stability, and a standalone verification price of 0.003 dollars that undercuts Tomba's bundled model at very large volumes. A single technical user should take Tomba on price; a five-person non-technical team should look hard at the seat structure before assuming Tomba is cheaper in practice.
Choose Tomba if
Developers and technical small teams building email finding, verification, or enrichment into their own product or internal tooling, and high-volume buyers who want a flat per-thousand price with twelve-month credit validity rather than a tier ladder.
Choose Voila Norbert if
Small teams and agencies who want a stable, long-established email finder with unlimited seats on a shared credit pool, and anyone who needs cheap standalone list verification or enrichment without committing to a subscription.

| Setup time | Fifteen minutes to a first API call: sign up, take the 75 free credits, pull an SDK, authenticate with the key and secret pair. The browser extension takes five. A production integration is a day or two depending on how many endpoints you use. | Ten minutes. Create an account, take the 50 free credits, and run a lookup or upload a CSV. Connecting a CRM adds fifteen minutes; an API integration is a few hours given the four client libraries. |
| Learning curve | Low for a developer and moderate for anyone else. The endpoint set is well enumerated and the SDKs are conventional. The concept that needs learning is the credit multiplier: emails cost one and phones cost five, so a phone-heavy workload burns a budget four times faster than the headline rate suggests. | Minimal. Norbert does one thing and the interface reflects that. The only thing worth learning is the certainty score, since treating a low-confidence result as verified is how people generate bounces and then blame the tool. |

Strengths and limitations
Tomba
Strengths
- A flat 8.90 dollars per thousand credits at every volume, which removes tier guessing entirely and is the cheapest published per-email rate in this batch.
- Explicit and correct billing rules: no charge for a failed search, no charge for a duplicate search inside the same month, and one credit per valid email.
- Twelve-month credit validity plus a one-time purchase option, so a finite project does not need a subscription it will forget to cancel.
- Ten official open-source SDKs across Python, Node.js, PHP, Ruby, Go, Java, Dart, Lua, R, and Elixir, which is broader language coverage than any competitor here.
Limitations
- The interface is a secondary concern; non-technical sales users will find Skrapp, SalesQL, or GetProspect better places to work.
- Phone lookups at five credits are poor value against SalesQL's single-credit pool if calling is your main channel.
- No searchable people database to filter by title and seniority, so Tomba answers questions about people you can already name rather than helping you decide who to contact.
- No per-second or per-minute API rate limits are published, only an uptime figure and a response-time claim, which is a real gap for a product sold primarily on its API.
Voila Norbert
Strengths
- Unlimited team members on every prospecting plan on a shared credit pool, which makes team economics far better than any per-seat competitor in this category.
- Credits are charged only for successful finds and roll over rather than expiring, so the allowance maps to results.
- Standalone pay-as-you-go verification at 0.003 dollars an email, dropping to 0.001 above 500,000, is a genuine commodity price that needs no subscription.
- Standalone enrichment priced per email with volume tapering, also with no subscription, which suits a one-off CRM cleanup.
Limitations
- No phone numbers at all, on any plan, at any price, which removes Norbert from consideration for any team that calls.
- Per-lead pricing is high: roughly 0.049 dollars at the entry tier against Tomba's 0.0089 and Skrapp's 0.0145, and the gap does not close at volume.
- No searchable people database, so Norbert cannot help you decide who to contact, only how to reach someone you can already name.
- The 98 percent success claim is a marketing figure with no contractual guarantee behind it, unlike Anymail Finder's written commitment.
Pricing compared
Tomba
Usage-priced credits at a flat rate per thousand, bought as a monthly subscription or as a one-time block, with twelve-month credit validity and no conventional tier ladder.
- Free$0
- Growth$89
- Custom volume$8.90 per 1,000 credits
Tomba is the cheapest published per-unit price in this batch and one of the cheapest anywhere self-serve. At 1,000 verified emails a month you spend 8.90 dollars in finder credits, roughly 0.0089 per address, against Skrapp at 0.0145, GetProspect at 0.034, and Hunter's Starter at about 0.025 euros. At 10,000 emails a month you spend 89 dollars, well under Hunter's Growth tier at 149 euros for the same volume and better than any tier-laddered competitor here. Phone numbers are the weak point: at five credits, 1,000 mobiles costs 44.50 dollars and 10,000 costs 445, which is respectable in absolute terms but four to five times SalesQL's single-credit pool. The honest summary is that Tomba is the best price per email in this batch and a middling price per phone, and it is worth the switch mainly if you are calling the API rather than clicking a button, because the interface does not justify the move on its own.
Voila Norbert
Subscription prospecting plans priced by monthly lead allowance with unlimited team members, plus separately priced pay-as-you-go verification and enrichment utilities, plus a distinct per-seat email sequencing product.
- Valet$49
- Butler$99
- Advisor$249
- Counselor$499
Per lead, Norbert is expensive: 1,000 finds for 49 dollars is about 0.049 each, five times Tomba's 0.0089 and more than three times Skrapp's 0.0145. At 10,000 you are on the 249 dollar Advisor tier paying about 0.025 per found address at your real volume, still well above the field. The case for Norbert therefore does not rest on unit price at all. It rests on unlimited seats, which for a five-person team turns a nominally expensive plan into a cheaper one than any per-seat competitor, and on the standalone verification price of 0.003 dollars per email, which is a genuine commodity rate that undercuts most dedicated verifiers and requires no subscription whatsoever. Buy the prospecting plan for the seat structure and the stability; buy the verification for the price. If you are a single user optimising cost per email, Norbert is simply the wrong choice and Tomba is the right one.
Editorial verdict on each
Tomba
Tomba is the best-value email lookup in this batch and the only one in it genuinely built for developers. Eight dollars ninety per thousand credits at every volume, with failed and duplicate searches free and credits valid for twelve months, gives an honest cost of under a cent per verified address, and ten open-source SDKs across fourteen endpoints is more API surface than anyone else here offers. The Author Finder endpoint and the Clearbit-compatible person and company endpoints are real differentiators rather than list padding. What is missing is everything around the API. There are no published rate limits, no seat terms, no searchable people database, no sequencer, a thin interface, and almost nothing disclosed about who runs the company. Phone lookups at five credits are middling value. Buy Tomba if code is calling it and price per verified email is the number that matters. Do not buy it as the tool a salesperson opens in the morning, and do not buy it as your phone data provider.

Voila Norbert is the least exciting product in this batch and, for a particular kind of buyer, the correct one. Per lead it is expensive, several times Tomba's rate and well above Skrapp or GetProspect, and it sells no phone numbers, has no searchable database, and publishes almost nothing about how its data is sourced. What it does have is a set of structural choices that quietly matter more than unit price for a small team: unlimited seats on every plan, credits that roll over and are charged only on success, bulk and API access included rather than gated, and standalone verification at 0.003 dollars an email that undercuts most dedicated verifiers and needs no subscription. Behind that is twelve years of trading and seven under stable profitable ownership without a single repositioning. Buy it if you are a team rather than an individual, if you value a vendor that will still be here in three years, or if you simply need to clean a very large list cheaply. Do not buy it if you are one person optimising cost per address, because in that comparison it loses to almost everything.
