Prospeo: Pricing, Features & What It Actually Does

An SDR builds a list of 200 prospects on LinkedIn Sales Navigator. The names and titles are right there, but not one email address is visible. Prospeo’s Chrome extension is built for exactly that gap — pull a name and company, get a verified work email back in a couple of seconds, without leaving the LinkedIn tab.

TL;DR

Prospeo is an email-finding and verification API and Chrome extension built for outbound sales and recruiting workflows. Give it a name and a company domain (or a LinkedIn profile through the extension), and it returns a verified email address, charging credits only when a valid result comes back rather than for every attempt. It also does mobile-number lookup and direct list export from LinkedIn Sales Navigator. It’s aimed at teams that want a lighter-weight, cheaper alternative to a full sales-intelligence platform for the specific job of finding and verifying emails. The main caveat worth knowing upfront: accuracy is strong in North America and Europe by most accounts, but at least one documented test found it drop off substantially in Asia-Pacific markets, and several reviewers report low match (“hit”) rates on certain list types despite the pay-on-success billing model.

What Prospeo does

Prospeo is built as a developer-facing API first, with a Chrome extension and a lightweight web app layered on top for people who don’t want to write integration code. It isn’t a people-search or prospecting database in the way Apollo or ZoomInfo are — it doesn’t help build a list of who to contact at a company. It helps find and confirm an email address for someone already identified some other way. That narrower scope is deliberate: rather than trying to compete with full sales-intelligence platforms on breadth, Prospeo focuses on doing the email-and-phone-finding piece cheaply and quickly enough to sit alongside whatever prospecting tool a team is already using.

Email finder and verification

The core endpoint takes a person’s name and company domain and returns a verified professional email address with a confidence indicator, drawing on a database described by the vendor as 300 million-plus professional email addresses, with a claimed average match rate around 63% and email accuracy near 98%. A separate verification-only endpoint checks an email address a team already has, at a lower credit cost than a fresh find, useful for cleaning an existing list before a send.

LinkedIn Sales Navigator export

The Chrome extension’s most distinct feature is direct export from LinkedIn Sales Navigator search results — pulling a filtered lead list, reportedly up to roughly 2,500 contacts per export and up to about 45 data points per record, without manually copying names one at a time. This is the workflow most reviewers describe as Prospeo’s practical daily use case: build a Sales Navigator search, export through the extension, get emails back attached to the list.

Mobile number lookup and bulk processing

Beyond email, Prospeo offers a mobile-number-finding endpoint, priced at a meaningfully higher credit cost than an email find because phone data is inherently harder to source reliably at scale, plus bulk search for processing larger lists through the API rather than one record at a time. For teams enriching a CRM in the background rather than working leads one by one, the bulk endpoint is generally the more practical entry point than the Chrome extension.

Pricing

Prospeo’s own pricing page didn’t return a usable table on direct fetch at the time of writing — the figures below are compiled from third-party pricing-tracking sites and should be confirmed directly at prospeo.io/pricing before budgeting.

Plan	Price/month	Credits
Free	$0	75 email credits + 100 Chrome extension credits
Basic	~$39	1,000 credits (~$0.039/credit)
Pro	~$99	5,000 credits (~$0.020/credit)
Business	~$199	20,000 credits (~$0.010/credit)
Corporate	~$369	50,000 credits (~$0.007/credit)

The billing model is pay-on-success: finding a verified email costs 1 credit, verifying an email already on hand costs roughly half a credit, and finding a mobile number costs around 10 credits, per third-party breakdowns of the credit structure. Credits do not roll over between billing cycles on monthly or annual plans — whatever’s unused at renewal expires, based on Prospeo’s own help documentation, which is worth factoring into which tier to pick since over-buying credits that then expire unused effectively raises the real cost per result. The headline per-credit price drops sharply at higher tiers, so a team with predictable, high monthly volume gets meaningfully better unit economics than one buying the entry tier repeatedly. Add-on credits can typically be purchased mid-cycle for teams that run out before renewal, though those follow the same non-rollover rule as plan credits, expiring at the end of the current billing period rather than carrying into the next one.

Pros

Pay only for valid results. Credits are charged on success, not on every attempt, so a search that comes back empty doesn’t cost anything — a meaningful difference from tools that charge per query regardless of outcome.
Fast Chrome extension workflow. Reviewers describe the extension returning verified emails in two to three seconds directly inside LinkedIn, letting reps stay in one tab instead of switching between a database tool and LinkedIn.
Strong reported accuracy in core markets. The vendor’s claimed 98% accuracy figure is echoed by several reviewers for US and European contacts specifically, which is where most of Prospeo’s target customer base operates.
Lower cost than full sales-intelligence platforms. For teams that already have a prospecting source and just need email finding bolted on, Prospeo’s per-credit pricing is meaningfully cheaper than paying for a full database subscription.
API-first design suits automated workflows. Teams enriching inbound leads or CRM records programmatically get a stable, documented API rather than being limited to a dashboard-only tool.

Cons

Accuracy drops outside core markets. One documented 500-contact test found accuracy near 98% for US/EU contacts but only around 60% for APAC contacts, meaning teams prospecting heavily in Asia-Pacific should test before committing budget.
Hit rates can be inconsistent on certain lists. At least one reviewer reported a hit rate as low as 4.5% on a 1,000-contact Sales Navigator export, with all 1,000 credits consumed in the attempt — a reminder that “pay on success” still means paying for the searches that do succeed, and a low-quality input list produces a low-quality (and possibly expensive) result regardless of billing model.
Credits expire, they don’t bank. Unused monthly or annual credits are lost at renewal rather than carrying forward, so overestimating usage wastes money more directly than with tools that let credits accumulate.
Not a prospecting tool. Prospeo assumes a team already knows who to contact; it doesn’t offer the filterable people-search functionality of a full database platform, so it’s typically a second tool alongside something else, not a replacement for one.
Support experience is inconsistently reviewed. Some reviewers describe responsive support, while others report slower or less helpful experiences, so response times may vary depending on plan tier or ticket volume.

How it compares

Hunter.io is the closest direct comparison — both are email-focused tools rather than full databases. Hunter is generally positioned as the deliverability-first option, with a longer track record and a reputation for prioritizing sender reputation over raw database breadth; it doesn’t offer phone-number lookup the way Prospeo does. For teams that want the cheapest reliable email-only tool and don’t need phone data, Hunter and Prospeo are often named together as the two budget-friendly picks in the category, with Prospeo’s edge being the added mobile-number and LinkedIn Sales Navigator export functionality.

Findymail is the other frequent comparison, positioned around bulk processing speed and a verification-bundled-with-finding approach — it only returns results that pass verification as a single step, aiming for a sub-2% bounce rate on delivered addresses. Reviewers generally treat Findymail as the choice for teams prioritizing bulk-list processing speed and the tightest bounce-rate guarantee, while Prospeo’s LinkedIn-native workflow and lower entry price make it the more practical pick for reps working lists inside Sales Navigator day to day rather than processing large batch files.

Who it’s for

SDRs already building lists in LinkedIn Sales Navigator. The Chrome extension’s direct export is built specifically around that workflow and is the feature most reviewers cite as the reason they use Prospeo day to day.

Teams that want to pay only for verified results. The success-based credit model suits teams wary of paying for searches that come back empty, though it doesn’t protect against paying for results on a poor-quality input list.

Recruiters sourcing candidates by name and company. The same name-plus-domain lookup that works for sales prospecting applies equally to recruiting workflows needing a way to reach a specific candidate.

Not the right fit for teams needing a searchable prospect database. Anyone who needs to discover who to contact at a company — not just verify an email for someone already identified — needs a people-search tool like Apollo or ZoomInfo in addition to, or instead of, Prospeo.

Developers building automated enrichment pipelines. The API-first design and bulk endpoint suit engineering teams wiring email verification into a signup flow, CRM sync job, or lead-scoring pipeline, where a browser extension used manually by one person wouldn’t scale.

Frequently asked questions

Is Prospeo free to use?

A free plan with a limited monthly credit allowance (reported as 75 email credits plus 100 Chrome extension credits) is available for testing, according to third-party pricing trackers, ahead of any paid commitment.

How accurate is Prospeo’s email data?

The vendor claims roughly 98% email accuracy on a database of 300 million-plus addresses. Independent testing reported in reviews generally supports that figure for US and European contacts specifically, but found meaningfully lower accuracy (around 60% in one test) for Asia-Pacific contacts.

Does Prospeo work with LinkedIn Sales Navigator?

Yes — the Chrome extension supports direct export of Sales Navigator search results, reportedly up to around 2,500 contacts per list with up to roughly 45 data points per record.

Does Prospeo find phone numbers, not just emails?

Yes, a mobile-number-finding endpoint is available, priced at a substantially higher credit cost per result than an email find. Phone data is generally harder to source and verify accurately across providers than email data, which is part of why the credit cost is higher.

Is Prospeo an API, a Chrome extension, or a dashboard tool?

All three, built API-first. The Chrome extension and web interface sit on top of the same underlying API that developers can also integrate directly for automated enrichment workflows.

Do Prospeo credits roll over?

No. According to Prospeo’s own help documentation, unused credits on both monthly and annual plans expire at the end of each billing cycle rather than carrying forward.

Prospeo states it processes only professional B2B data under lawful bases, supports data subject rights including access, rectification, and erasure, signs data processing agreements where required, and maintains a global opt-out and suppression list, per its published trust center materials.

What’s the difference between Prospeo and Hunter.io?

Hunter is generally described as the deliverability-focused, no-phone-data option with a longer track record; Prospeo adds phone-number lookup and native LinkedIn Sales Navigator export on top of email finding, at a broadly comparable budget price point.

Does Prospeo charge for searches that don’t find anything?

No — the billing model charges credits only when a valid result is returned (a full credit for a found email, a fraction for a verified one), not for attempts that come back empty, per the vendor’s published credit structure.

Can Prospeo replace a full prospecting database like Apollo?

No. Prospeo verifies and finds emails for people already identified by name and company; it doesn’t offer the filterable company/contact search that a database platform provides for discovering who to contact in the first place.

Does Prospeo offer a Chrome extension?

Yes, and it’s the feature most reviewers describe using day to day — it overlays on LinkedIn and Sales Navigator profiles and returns a verified email in a few seconds without needing to switch to a separate tab or tool.

How does Prospeo’s bulk search work?

The bulk endpoint accepts a list of names and company domains through the API and returns matched, verified results at scale, aimed at teams enriching larger lists or CRM records programmatically rather than searching one contact at a time through the extension.

Verdict

Prospeo is a reasonable choice for a team that already has a way to find prospects — LinkedIn Sales Navigator, a CRM, an existing list — and just needs a fast, reasonably priced way to attach verified emails to it, especially for US and European contacts where its accuracy claims hold up best in independent testing. It’s a weaker choice as a standalone prospecting tool, since it has no people-search functionality of its own, and teams targeting Asia-Pacific markets heavily should test accuracy directly before relying on it. Given the pay-on-success pricing and a free tier to test against, running a real sample list before committing to a paid plan costs nothing but a few minutes and settles the accuracy question better than any published percentage can — pull a batch of contacts from the actual regions and industries a team prospects into, and let the hit rate on that specific list decide the tier, not just the headline accuracy figure.
