Prospeo Review 2025: Full Test, Pricing & Honest Verdict

Struggling with poor contacts in B2B prospecting? Emails bouncing at 30%, outdated phone numbers, a CRM that looks like a graveyard? I've been testing Prospeo for several months for my cold emailing campaigns and prospecting workflows. Here's my honest review of this tool.

Spoiler: Prospeo is excellent for data quality. But watch out for the credit model that can quickly become a trap if you do high volumes.

Summary of My Prospeo Review

After several months of intensive use, here's what I take away: Prospeo is an excellent tool for B2B data enrichment, especially if you're looking for ultra-verified emails and mobile numbers. I've tested more than 15 enrichment tools, and frankly, the 98% deliverability rate that Prospeo claims is not marketing bullshit.

What really rocks:

- Real-time verified data with an impressive validity rate

- Chrome extension that lets you prospect directly from LinkedIn Sales Navigator

- Mobile Finder that gives you B2B mobile numbers (and believe me, it changes everything for response rates)

- Ultra-simple interface, even my intern understood it in 2 minutes

- Catch-all email verification system (a real technical plus)

What's problematic:

- The credit model quickly becomes expensive for large volumes (+200k listings)

- Bulk processing that sometimes struggles with domains

- Customer support that varies according to feedback I've seen

My advice: If you do less than 20,000 contacts per month and want pure quality, go for it. If you do mass volume, think about the cost per lead.

| Advantages | Disadvantages |

|---------------|-------------------|

| ✅ Verified data (emails & mobiles) | ❌ Expensive credit model for large volumes |

| ✅ 98% deliverability rate | ❌ Bulk processing not yet optimal |

| ✅ Ultra-intuitive interface | ❌ Variable customer support according to feedback |

| ✅ B2B mobile number search | |

| ✅ Chrome extension | |

| ✅ Responsive customer support | |

What is Prospeo exactly?

Prospeo is a B2B data enrichment tool that finds and verifies professional emails and mobile numbers. Period. No marketing blabla, that's their job.

For whom? Sales reps, SDRs, Growth Marketers, founders who do outbound and are tired of wasting time with poor data.

The problem they solve: You have a list of prospects on LinkedIn, names in an Excel file, or a company domain. Prospeo extracts verified emails and mobile numbers in seconds.

What differentiates them from Apollo, Hunter, or Lusha? Their proprietary catch-all email verification system. Basically, these "trash" emails that accept all messages but don't always deliver them. Prospeo can determine whether the email will really be delivered or not. It's technically impressive.

Important context: Don't confuse Prospeo with Prospero. Prospero is software for creating commercial proposals. Prospeo is 100% data enrichment. Two completely different tools.

I've been using Prospeo for 8 months now, and frankly, my listing quality has gone from an empty Google sheet to an actionable database. But let's be clear: it's not magic, and there are limits that I'm going to tell you about.

Features: Deep Dive on What Really Works

Email Finder: The Search That Doesn't Mess Around

Your browser does not support video.

The Email Finder is the main feature. You enter first name + last name + company (or domain), and Prospeo gives you the email in seconds.

How does it work technically?

Prospeo uses several methods:

- Detection of company email patterns (firstname.lastname@, flastname@, etc.)

- Real-time validation via SMTP

- MX record and domain verification

- Catch-all test and determination of real deliverability

What I've found in the field:

- Validity rate around 95% on my tests (on 2,500 emails searched)

- Works even for companies with complex email patterns

- If the email has already been searched, it's free (smart cache)

Costs:

- 1 credit per valid email found

- 0 credit if the email is catch-all (risky) or not found

- 0 credit if the email has already been searched before

Concrete use case: I set up a cold emailing campaign for a client in B2B HR SaaS. I had a list of 1,000 Senior Talent Acquisition / HRD / Head of Recruitment on Sales Navigator. Prospeo found 847 emails, of which 812 were valid after verification. Final bounce rate: 1.8%. That's very strong!

The limit: On some large companies (like Google, Microsoft), you often find generic emails like info@ or contact@. Normal, individual emails are not public.

Mobile Finder: The Game-Changer for Cold Calling


The Mobile Finder is THE feature that changes everything if you do cold calling or if you want to complete your email sequences with phone.

How it works: You enter the prospect's LinkedIn profile URL, and Prospeo gives you their professional mobile number. Not the company number. The direct mobile.

Cost: 10 credits per valid mobile found. Yeah, it's expensive. But frankly, if you do B2B cold calling, having a mobile number vs a company switchboard is day and night.

My feedback: I tested on 500 LinkedIn profiles of VP Sales and CMO in France. Prospeo found 287 mobile numbers (57% rate). Of these 287 numbers:

- 271 were valid and reachable (94%)

- 16 were landlines or invalid (normal with solutions like OneOff / Ringover / Aircall..)

Business impact: My response rate on calls almost doubled (from 12% to 21%) using mobiles rather than switchboards. And yes, it's more expensive in credits, but the ROI is there.

Pro tip: Combine email + mobile in your sequence. Email on Monday, email reminder on Wednesday, mobile call on Friday. Contact rate explodes.

Email Verifier: No More Bounces That Kill Your Reputation

The Email Verifier is simple: you already have a list of emails (that you got elsewhere), and you want to verify they're valid before sending your campaign.

Why is it crucial? If you send to more than 5% invalid emails, your sender reputation tanks. Gmail, Outlook and other ESPs put you in spam.

What Prospeo does:

- Real-time verification

- Catch-all detection with risk scoring

- Identification of temporary/disposable emails

- Domain and MX record check

Cost: 0.5 credit per verified email (valid or invalid). The catch-all recovery system is included.

My test: I had a list of 3,000 emails recovered from an old file of CEOs/Founders. After passing through Prospeo:

- 2,234 valid emails (74%)

- 512 invalid emails (17%)

- 254 risky catch-all emails (9%)

I sent my campaign only to the valid ones. Bounce rate: 1.2%. Without verification, I would have been at 26% bounce. My reputation would have been destroyed.

Comparison with competitors: I did comparative tests with ZeroBounce and NeverBounce. Prospeo is just as accurate, but cheaper on large volumes if you take an annual plan.

Chrome Extension: Ninja Mode Prospecting


The Prospeo Chrome extension is your best ally for on-the-fly prospecting. You're on LinkedIn Sales Navigator, you see a profile you like, one click and boom: email + mobile extracted and verified.

What's crazy:

- Works on LinkedIn (individual profile + Sales Nav)

- Works on company websites

- Works even on Google search results

- Data displays directly on the page

My daily workflow:

1. I do my search on Sales Navigator (e.g., "VP Sales" + "SaaS" + "France" + "500-1000 employees")

2. I scroll through the results list

3. For each profile that matches my ICP, I click on the Prospeo extension

4. Email + mobile appear in 2 seconds

5. I add them directly to my list or CRM

Real time savings: Before Prospeo, I did this manually. I took the LinkedIn info, put it in Hunter, then in NeverBounce, then looked for the mobile on Kaspr. Time per contact: 3-4 minutes. With Prospeo: 10 seconds. On 100 contacts, I save 5h30.

The limit: The extension doesn't work with LinkedIn Recruiter (only Sales Navigator). If you're a recruiter, it's annoying.

Domain Search: Find All Emails from a Company

Domain Search is simple: you enter a company name or its domain (e.g., "salesforce.com"), and Prospeo lists all the emails it has in its database.

Cost:

- 1 credit per search (returns up to 50 emails)

- 1 additional credit per 50 additional emails

- Verification of found emails costs 0.5 credit per valid email

Use cases:

- You want to map a company (identify all decision-makers)

- You're looking for several people in the same company

- You want to bypass a generic email like info@

My feedback: It's practical for Account-Based Marketing (ABM). For example, I did a search on "leboncoin.fr": 87 emails found, of which 54 verified valid. I was able to directly contact several stakeholders instead of going through the generic contact.

Warning: Found emails are not necessarily verified. You need to pass them through the verifier afterward (0.5 credit per email).

Bulk Processing: Mass Processing (with Its Limits)

Bulk Processing is for processing entire contact lists in bulk. You upload a CSV file with your data (name, first name, company), and Prospeo gives you the emails and mobiles.

What's good:

- You can process up to 2,500 profiles simultaneously

- The final report clearly tells you what worked or not

- It's faster than doing one by one

What's problematic (and this is where Prospeo has limits): According to my experience and several user feedbacks I've seen on G2 and in Growth forums:

- Bulk only works well if you have the company domain

- If you only have the company name (without domain), results are less good

- Some users have reported a match rate of only 4-5% on large LinkedIn lists

My personal test: I uploaded a list of 500 contacts extracted from Sales Navigator (with well-defined names + companies). Results:

- 312 emails found (62%)

- 89 mobiles found (18%)

The rate isn't great, but the quality of the data found was top. Of the 312 emails, 97% were valid.

Technical limit: Prospeo limits scraping to 5,000 profiles from Sales Navigator. If you do massive industrialization, it's a brake.

Prospeo Pricing: Detailed Analysis of the Credit Model

Let's be straight: Prospeo's pricing is simple to understand but can become expensive depending on your usage. It's a credit model, like many enrichment tools.

Different plans (US prices in $)

| Business | 50,000 credits | $369 | ~$258 | ~$3,096 |


How Are Credits Consumed?

This is where it becomes crucial to understand:

Email Finder:

- 1 credit per valid email found

- 0.5 credit per verified email (valid or invalid)

- The catch-all recovery system is included

- 1 credit per search (returns up to 50 emails)

- 1 credit per 50 additional emails

- Email verification costs 0.5 credit extra per email

My Economic Analysis (the Real Costs)

Let's take concrete cases I use daily:

Scenario 1: I do pure prospecting (emails only)

- Growth plan: 5,000 credits / $99 per month

- Cost per email found and verified: about $0.02 (1 credit to find)

- Number of complete contacts possible: 5,000 contacts / month

- If I want to verify emails I already have: $0.01 per email (0.5 credit)

Scenario 2: I want emails + mobiles

- Growth plan: 5,000 credits / $99 per month

- If I search email (1 credit) + mobile (10 credits) = 11 credits per complete contact

- Number of complete contacts possible: 454 contacts / month

- Cost per complete contact: $0.22

Scenario 3: I do ABM with bulk

- Pro plan: 20,000 credits / $199 per month

- List processing with verification: about 1.5 credits per contact on average

- Capacity: about 13,000 contacts / month

- Cost per contact: $0.015

Comparison with Competition

Apollo:

- Email + mobile: plan starting at $49/month for 1,200 credits

- More expensive per credit but includes CRM and sequences

FullEnrich (waterfall enrichment):

- Starting at $29/month for 1,000 credits

- Waterfall on 15+ data providers, so better coverage

Lusha:

- Starting at $39/month for 500 credits

- More expensive than Prospeo

My verdict on pricing: Prospeo is competitive on email alone, but becomes expensive if you want emails + mobiles in bulk. The credit model is transparent, but be careful: credits don't roll over from month to month on monthly plans (only on annual).

Concrete Use Cases: How I Use Prospeo Daily

The Real Advantages of Prospeo (What I Validated in the Field)

1. Data Quality is Real

I've tested 15+ enrichment tools (Apollo, Lusha, Hunter, Kaspr, ContactOut, etc.). Prospeo is in the top 3 for email accuracy. The validity rate claimed at 98% is not bullshit. On my real tests, I'm around 95-97%, which is excellent.

2. The Catch-All Verification System is a Real Plus

Most tools tell you "it's a catch-all, deal with it". Prospeo goes further: it determines whether the catch-all email will really deliver or not. It's a massive technical advantage.

3. Sales Navigator Integration is Smooth

The Chrome extension works perfectly with Sales Navigator. It's really plug-and-play. In 2 clicks, you have your email and mobile. It's life-changing.

4. Ease of Use

Even if you're not technical, you understand Prospeo in 5 minutes. The interface is clear, no useless features, everything is oriented towards efficiency.

5. Mobile Finder Changes the Game for Cold Calling

Having direct mobile numbers (not company switchboards), it doubles your contact rate in cold calling. It's a fact. Prospeo is one of the few to offer this at this scale.

6. The Credit Model is Transparent

No surprises on the bill. You know exactly what you consume. Some tools are more opaque on pricing.

The Real Limits of Prospeo (Let's Be Honest)

1. The Credit Model Becomes Expensive on Large Volumes

If you do massive industrialization (like 50,000+ contacts/month), Prospeo becomes expensive. The Business plan at $369/month for 50,000 credits is expensive. At this level, tools like Apollo or waterfall solutions like FullEnrich are more profitable.

2. Credits Don't Roll Over (on Monthly)

On monthly payment, if you don't use all your credits, you lose them. It's frustrating. Solution: go annual, where you get all the credits upfront.

3. Bulk Processing Has Limits

According to several user feedbacks (and my own tests), bulk processing doesn't work as well as unit use. Match rates are lower, especially if you don't have well-defined company domains.

4. No Native Backend Search

Unlike Apollo or Lusha, Prospeo doesn't have an integrated search engine to build lists. You need to come with your own lists (from Sales Navigator, a file, etc.). It's more an enrichment tool than an end-to-end prospecting tool.

5. Customer Support is Variable

I've read contradictory feedback. Some users say support is great and responsive, others talk about tickets unresolved for weeks. My personal experience: I got responses in less than 24h on 3 tickets, but I've seen less positive reviews.

6. No LinkedIn Recruiter

The extension only works with LinkedIn Sales Navigator, not with LinkedIn Recruiter. If you're a recruiter, it's a problem.

7. Coverage is Not Perfect

Prospeo doesn't find 100% of emails. On my tests, the match rate is around 70-80% (which is in the high average of the market). To increase coverage, you need to combine with other sources.

My Final Verdict: Should You Go for Prospeo?

After several months of use and tens of thousands of contacts processed, here's my straight verdict:

Prospeo is an excellent B2B enrichment tool if you're looking for quality rather than quantity. The 98% deliverability rate, the Mobile Finder, and the ease of use make it a solid tool for sales and growth teams who want reliable data.

You should go for Prospeo if:

- You do less than 10,000 enriched contacts per month

- Data quality is your #1 priority

- You want B2B mobile numbers for your cold calls

- You use Sales Navigator for your prospecting

- You want a simple and effective tool without hassle

You should look elsewhere if:

- You do massive industrialization (50,000+ contacts/month)

- You want an all-in-one tool with integrated CRM and sequences

- You use LinkedIn Recruiter (not Sales Navigator)

- You want to maximize coverage at all costs (waterfall)

- Budget is ultra-tight and you do large volumes

What I Would Do in Your Place

Scenario 1: Freelance / Small Sales Rep

Start with the free plan (75 credits). Test on your first 50-75 contacts. If the results are there, move to Starter at $39/month.

Scenario 2: Startup / SME with Sales Team

Take the Growth at $99/month. It's the quality/price sweet spot. 5,000 credits gets you about 300-400 complete contacts (email + mobile) per month, or 5,000 emails alone.

Scenario 3: Scale-up / Large Team

Either you take Pro ($199/month), or you combine Prospeo for quality + a waterfall tool like FullEnrich for coverage.

My Personal Use

I'm on the Growth plan ($99/month annual, so $69/month real). I use Prospeo for:

- Enriching my Sales Navigator lists (2-3 times per week)

- Verifying my existing lists before my cold email campaigns

- Finding mobiles for my top prospects

I complement with other tools (Apollo for the database, Clay for workflows, Lemlist for sequences), but Prospeo remains my reference tool for pure enrichment.

The Verdict in One Sentence

Prospeo is excellent for B2B data quality. Yes, the credit model has a cost, but a single deal signed thanks to clean data largely pays for the subscription. If you do serious outbound, it's an investment that makes sense.
