In today’s data-driven marketing landscape, finding accurate contact information — especially verified email addresses and mobile phone numbers — is paramount for outreach success. If you’ve been scavenging through directories, manually verifying stale contacts, or disappointed by low deliverability rates, you’re not alone. That’s where Prospeo comes in. I’ve spent several weeks using Prospeo in real outreach campaigns. In this in-depth review, I’ll walk you through what works, what doesn’t, and whether this tool is worth integrating into your sales stack.
What is Prospeo?
Prospeo is a cloud-based lead generation tool designed to help businesses and marketers find, verify, and enrich contact data — primarily emails and mobile numbers — to improve outreach and cold outreach effectiveness. It is used by over 2,000 companies globally.
Prospeo’s services include:
- Email Finder – Find any professional email from first name, last name, and company.
- Domain Search – Discover all email addresses associated with a given domain.
- Mobile Finder – Obtain mobile numbers for B2B contacts.
- Email Verifier – Test whether an email is deliverable. This helps reduce bounce rates.
- Chrome Extension – Extract contact data while browsing, directly from websites or search results.
- API Access – For integrating contact-finding and verifying capabilities into your own app or workflow.
Key Features & Highlights
Here are the standout features that make Prospeo attractive:
- High Data Quality & Deliverability
Prospeo guarantees up to 98% deliverability of emails, ensuring that most of the addresses you find are valid and usable. - Bulk Processing
You can upload spreadsheets (lists of companies, names) to find or verify emails or mobile numbers in bulk. This drastically reduces manual workload. - Free Plan & Generous Credits
The free forever plan gives you 75 credits per month, allowing some usage without investment. Great for testing or small-scale outreach. - Chrome Extension
Being able to find contact data while browsing — e.g. seeing emails or phone numbers associated with websites you visit — is very useful. It streamlines the discovery process. - API Availability
For tech teams, integration is smooth. Prospeo’s API supports endpoints for email finder, mobile finder, domain search, and verification. - Free Tools & Ease of Use
The interface and dashboard are user-friendly. Exporting data, managing leads, customizing how you receive the exports are well designed. Users often remark on the UX being better than many competitors.
Who Should Use Prospeo?
Based on my hands-on experience, Prospeo works best for:
- B2B marketers & sales teams who need accurate contact data for outreach campaigns, cold emails, or cold calls.
- Startups and SMEs who want affordable, reliable tools without huge budgets but high expectations.
- Agencies managing outreach campaigns for multiple clients and needing bulk processing, verification, and integration via API.
- Growth hackers / Lead generation specialists who rely on verified contacts to optimize deliverability and conversion.
- Anyone doing LinkedIn / website scraping who wants to validate and enrich contact data.
Less suitable if you are purely consumer-oriented (B2C) and don’t need business email/mobile data, or if you already have an enterprise contract with tools that offer similar or better local data.
How It Works (Workflow / Use Case)
Here’s how using Prospeo typically plays out in a real campaign:
- Sign Up & Free Plan
Create an account. Use the free plan to test features. You’ll get 75 monthly credits that you can use to find or verify contacts. - Choose Your Tool
Depending on your goal, pick:- Email Finder → when you know the person’s name & company.
- Domain Search → when you want all possible emails linked to a company.
- Mobile Finder → to add cell numbers to your outreach.
- Email Verifier → to clean your existing list.
- Input Data / Upload Leads
Enter name + company, domain, or upload spreadsheets. For bulk tasks, you can upload a list and let Prospeo process it. - Verification / Enrichment
After finding raw contact info, verify emails to reduce bounce. Use mobile finder for added touchpoints. - Export & Outreach
Export your data via CSV/Excel or use API to integrate into your CRM or outreach tool (e.g. Mailchimp, HubSpot, etc.). - Use the Chrome Extension
While browsing, extract contact data from public websites, company pages, Google search results etc. Useful when spotting leads in news articles, directories, LinkedIn, etc. - Scale & Maintain
Clean your lists often. Use verification to keep bounce rates low. Monitor deliverability, refine domains or sources that produce lower quality data.
Pricing
Here’s what I found in terms of pricing tiers (as of this review; always double-check on the Prospeo site for updates):
The exact pricing for higher tiers is not fully disclosed publicly without logging in or contacting sales. But based on user reports and the site, the cost is competitive vs. alternatives like Hunter, Snovio, Apollo, etc., especially when you account for the high deliverability and inclusion of mobile number data.
Pros & Cons
Based on my experience and comparison with similar tools, here are the strengths and limitations:
| Advantages | Drawbacks |
| High deliverability & accuracy – reduces bounce, more responses. | Mobile data can be spotty in certain regions; for some companies/names mobile numbers aren’t always found. |
| Free plan with reasonable credits – you can test before committing. | Limited public pricing transparency for large-scale / enterprise usage, making it hard to know exact cost until you engage with sales. |
| Bulk features and API – good for teams & scaling. | Data freshness / coverage may vary by industry or region; some emails or mobiles flagged uncertain. |
| Chrome extension + ease of use – minimal learning curve. | Credit usage: heavy users might consume credits quickly when verifying or processing large lists. |
| Includes mobile finder – many tools skip this. | Support in niche markets might be less robust; certain domain name types or small companies might have missing data. |
FAQs
Q1: How accurate are Prospeo’s email addresses and mobile numbers?
A: Prospeo claims up to 98% deliverability for emails. In my tests, most of the emails found were valid; a small percentage (perhaps 2-5%) were unusable or bounce-prone. Mobile numbers depend heavily on region and publicly available sources, so accuracy is good but less uniform than email.
Q2: What are credits and how are they used?
A: Credits are the unit by which you use Prospeo’s tools (searches, verifications, mobile lookups etc.). The free plan gives about 75 credits/month. Paid plans give many more. Every action (finding, verifying) consumes credits.
Q3: Can I integrate Prospeo with my CRM or automation tools?
A: Yes. Prospeo offers an API with endpoints for email finder, mobile finder, domain search, etc. You can export CSVs or use the API directly to push data into your CRM.
Q4: Is the Chrome extension useful?
A: Absolutely. The extension allows you to get contact info while browsing websites (company homepages, directories, etc.) or search results. It speeds up discovery significantly. In my workflow, this saved lots of time vs manually entering data into the dashboard.
Q5: Who should avoid using Prospeo?
A: If your focus is purely B2C (non-business), or your leads don’t require business email/mobile, many features may be unnecessary. Also, if you need extremely local, very niche datasets (e.g. certain small markets with weak public data), some contacts might be missing or less accurate.
Conclusion
After using Prospeo extensively in real outreach efforts, I can confidently say that it delivers solid value for B2B teams, growth marketers, startups and agencies that need high-quality, verified contact information. Its strengths — high email deliverability, reasonable pricing, inclusion of mobile data, simple UI, and useful API — make it a competitive alternative to more established players in the market.
If you’re seeking to improve your cold outreach, reduce bounce rates, scale lead generation, or enrich your existing contact lists, Prospeo is definitely a tool worth trying. Start with the free plan (using the free credits) to test it, evaluate deliverability in your industry/regional context, and then consider upgrading if you need bulk volume.
