Gamalogic vs Prospeo: Email Verifier or Full B2B Data Platform?
One tool verifies emails. The other finds, verifies, enriches, and delivers them with mobile numbers and intent data attached. Comparing Gamalogic vs Prospeo is like comparing a screwdriver to a toolbox - both useful, but they solve different problems. If you've been stacking three or four tools to build and clean prospect lists, that's the real issue this comparison exposes.
30-Second Verdict
Prospeo wins for most outbound teams. It's a full B2B data platform - 300M+ profiles, 143M+ verified emails, 125M+ mobile numbers, intent data, CRM and CSV enrichment - with verification built in. You don't need a separate tool to clean what's already verified.
Gamalogic wins if you only need cheap list cleaning. It's a solid standalone verifier with great Google Sheets integration and rock-bottom pricing. If you already have contacts and just need to scrub them, Gamalogic does the job for pennies.

What Each Tool Actually Does
Gamalogic
Gamalogic is a standalone email verification platform with a developer-friendly RESTful API. You feed it email addresses - via API, CSV upload, or Google Sheets - and it tells you which ones are valid, invalid, catch-all, or unknown. Throughput hits 100,000 emails per hour, which is solid for bulk cleaning jobs. The API returns granular sub-statuses for disposable, role-based, and spam-trap addresses, plus a did_you_mean field that catches typos before they become bounces.
The Google Sheets add-on is genuinely useful for teams that live in spreadsheets. No code, no exports, just highlight a column and run. Gamalogic holds a 4.8/5 on G2 from 13 reviews and 4.7/5 on Trustpilot from 34 reviews. One Reddit user who's run Gamalogic for 3+ years reports it produces fewer "unknown" results than ZeroBounce or NeverBounce, with surprisingly fast support responses. Trustpilot reviewers specifically praise its catch-all validation for improving open rates. One caveat: reviewers note that integrations beyond Google Sheets often require development knowledge, so if you aren't comfortable with API calls, you'll feel the limitation quickly.
Prospeo
Prospeo is a full B2B data platform where verification is one feature among many. The database covers 300M+ professional profiles with 143M+ verified emails and 125M+ verified mobile numbers, all refreshed on a 7-day cycle (the industry average is six weeks). Beyond verification, you get 30+ search filters covering buyer intent, technographics, job changes, and funding signals. Enrichment returns 50+ data points per contact, and the API match rate is 92%.
Intent data tracks 15,000 topics via Bombora. Snyk's 50-person sales team saw bounce rates drop from 35-40% to under 5% after switching. The Chrome extension has 40K+ users and native integrations push contacts directly into Salesforce, HubSpot, Smartlead, Instantly, Lemlist, and Clay.
You're comparing a verifier to a platform - and that's the point. Prospeo gives you 143M+ verified emails, 125M+ mobile numbers, intent data across 15K topics, and CRM enrichment in one tool. Verification is built in, not bolted on.
Stop paying for four tools when one does it all at 98% accuracy.
Accuracy: Claims vs Reality
Gamalogic claims 99.6% accuracy. That's an aggressive number, and user reviews tell a different story - accuracy typically lands around 80-90% in practice. That gap matters. Every percentage point of bad data chips away at your sender reputation, and invalid emails cost B2B companies roughly $847 per sales rep annually in wasted outreach and domain damage.
Prospeo's 98% accuracy runs across 143M+ verified emails using a proprietary 5-step verification process that includes catch-all handling, spam-trap removal, and honeypot filtering - not just basic SMTP checks. For context, benchmarks show observed accuracy across major tools ranging from 95.9% to 98.9%, with roughly 28-30% of B2B domains running catch-all configurations. In our testing, catch-all domains are where the real accuracy gap between tools shows up.
Pricing Compared
| Tier | Gamalogic | Prospeo |
|---|---|---|
| Free | $0 for 1,000 credits | 75 emails + 100 ext. credits/mo |
| 10K emails | $15 | ~$100 |
| Cost per email | ~$0.0015 | ~$0.01 |
| What's included | Verification only | Find + verify + enrich + mobiles + intent |
There's some inconsistency in Gamalogic's published pricing - G2 lists the Starter plan at $15 for 10,000 credits, but Gamalogic's own blog references $15 for 5,000 emails. Worth double-checking their site before you commit.
Here's the thing: Gamalogic is cheaper per email if all you need is verification. ZeroBounce charges ~$90 and NeverBounce ~$80 for 10K verifications, so Gamalogic undercuts both significantly. But Prospeo at ~$0.01/email replaces your email finder, your verifier, your mobile number provider, your data enrichment tool, and your intent data layer. If you're currently paying for three or four separate tools, the consolidated cost-per-contact is almost certainly lower than your stack.
For teams sending under 1,000 emails per month, Gamalogic's free tier handles verification fine. But the moment you need to find contacts - not just clean them - you're paying for a finder, a verifier, and probably a phone number tool. At that point, a single platform saves money and headaches.
Beyond Verification
This is where the comparison stops being close.
| Capability | Gamalogic | Prospeo |
|---|---|---|
| Email verification | Yes | Yes |
| Email finding | Basic API | 143M+ verified emails |
| Mobile numbers | No | 125M+ verified (30% pickup rate) |
| Intent data | No | 15K topics (Bombora) |
| Enrichment (CRM/CSV/API) | No | 92% match rate, 50+ data points |
| Chrome extension | No | 40K+ users |
| 30+ search filters | No | Yes |
| Native CRM integrations | No | Salesforce, HubSpot, + more |
Let's be honest - if you're doing outbound at any real volume, verification alone doesn't cut it. We've watched teams cobble together a finder from one vendor, a verifier from another, a phone number tool from a third, and then wonder why their data doesn't match across systems. Consolidation isn't just about cost. It's about data consistency.
When to Pick Which
Pick Gamalogic If
You already have contact lists and just need to clean them. Budget is tight and verification is the only thing you're buying. You live in Google Sheets and want a no-code add-on that just works. Or you're running a waterfall verification setup and need a cheap secondary checker - the consensus on r/coldemail is that stacking a $15 second pass behind your primary verifier catches edge cases without blowing your budget.
Skip Gamalogic if you need to find contacts, not just verify ones you already have. It doesn't do prospecting.
Pick Prospeo If
You need to find contacts and verify them in one workflow. You want mobile numbers and intent data alongside emails. You're running outbound at scale and can't afford bounces tanking your domain. Or you want to skip the waterfall entirely - the 5-step verification handles catch-all resolution in one pass with a 7-day data refresh.
We've used both tools in outbound workflows, and the difference in workflow efficiency is stark. Gamalogic does one thing well. But when you're stitching together four tools, the time cost alone justifies consolidating into a single platform. Stack Optimize built from $0 to $1M ARR using Prospeo, maintaining 94%+ deliverability and under 3% bounce rates across all their clients - that's the kind of result you get when your data source and verification layer are the same system.
Gamalogic cleans lists. Prospeo builds them. 300M+ profiles, 30+ search filters, 7-day data refresh, and a 92% API match rate - so the contacts you pull are already verified before they hit your CRM. Teams using Prospeo book 35% more meetings than Apollo users.
Find, verify, and enrich contacts in one workflow - no stacking required.
FAQ
Is Gamalogic accurate enough for cold outbound?
Gamalogic claims 99.6%, but users report 80-90% in practice. A 90% accuracy rate can leave up to 1,000 bad addresses per 10,000 sends - enough to wreck sender reputation. Double-check catch-all results at minimum, or use a tool with built-in catch-all handling.
Can Prospeo replace Gamalogic entirely?
Yes. Prospeo includes email verification as part of its 5-step process, plus email finding, 125M+ mobile numbers, CRM enrichment, and intent data. The free tier (75 emails/month) lets you test accuracy before committing.
Do I need two verification tools?
Most teams don't if their primary tool handles catch-all domains well. A 5-step verification process with dedicated catch-all handling and spam-trap removal reduces the need for a second verifier. Stack a second tool only if you're sending 50K+ emails monthly and want an extra safety net.
