Captain Verify vs SalesQL: A Finder and a Verifier Walk Into a Comparison
Comparing Captain Verify to SalesQL is like comparing a car wash to a car dealership. One cleans what you already have. The other gets you something new. They solve fundamentally different problems - an email finder discovers addresses from inputs like a name plus a company domain or profile URL, while an email verifier checks whether an existing address is valid before you hit send.
The real question isn't which tool is "better." It's which problem you actually have right now, and whether you need two tools or one that handles both. We've tested both, and the difference is immediately obvious.
30-Second Verdict
- Already have a list that needs cleaning? Captain Verify. Cheap SMTP-based verification, servers in France, unknowns re-credited.
- Need to find emails from scratch? SalesQL. Browser extension pulls contact data from professional profiles, with a usable free tier.
- Want finding + verification without juggling two tools? Skip both. Prospeo combines 300M+ professional profiles with 98% email accuracy and real-time verification in one platform. Free tier: 75 verified emails/month.
What Captain Verify Does
Use this if you're sitting on a marketing list of 10,000-500,000 contacts and need to scrub it before a campaign. Captain Verify runs SMTP-based checks - syntax validation, MX record lookups, and mailbox-level pings - without actually sending an email. If a result comes back "unknown," those credits get returned to your account. That's a nice touch most verifiers don't offer.
Their servers are in France with ISO 27001 and SOC certification, which matters if you're operating under GDPR. The tool carries a 4.5/5 on Capterra across 19 reviews, with users praising how easy it is to use and the detailed verification results. One nuance worth knowing: bulk checks and single checks can sometimes produce different outcomes when a mail server is temporarily unreachable, so budget for occasional re-checks on borderline results.
Skip this if you don't have emails to verify. Captain Verify doesn't find contacts - it only validates them. Also, one Capterra reviewer flagged a GDPR concern about being added to a mailing list after signing up (the vendor responded publicly). Check their data processing terms before going all-in.
What SalesQL Does
SalesQL takes the opposite approach. Instead of cleaning existing data, it generates new data from scratch.
The Chrome extension pulls contact information - work emails, personal emails, phone numbers - from professional profiles and lets you bulk-export from search pages to CSV. It handles roughly 25 profiles at a time. Their database covers 127M work emails, 89M personal emails, and 30M phone numbers. They also bundle a built-in email verifier with separate credit pools: 100 on Free, then 5,000-20,000 depending on plan.
SalesQL holds a 4.5/5 on G2 with 166 reviews. On Reddit, recruiters call it cheap and praise the CSV export workflow - one user in r/recruiting tested SalesQL against Seamless and SignalHire and concluded SalesQL delivered "same or better info, way cheaper."
Skip this if you need a full outbound platform. SalesQL's "Campaigns" feature is still listed as "Coming Soon," so you'll need a separate sequencer. G2 reviewers also flag occasionally outdated data, limited credits on lower tiers, and slow customer support responses.
Why pay for SalesQL to find emails and Captain Verify to clean them? Prospeo's 300M+ profiles come pre-verified at 98% accuracy - no CSV exports, no re-imports, no wasted credits between two dashboards.
One tool. One credit pool. 75 free verified emails every month.
Pricing Breakdown
Captain Verify
Captain Verify uses one-time credit packs (subscriptions save ~10%):
| Volume | Price | Cost/Email |
|---|---|---|
| 1,000 | EUR 7 | ~EUR 0.007 |
| 10,000 | EUR 60 | ~EUR 0.006 |
| 50,000 | EUR 150 | ~EUR 0.003 |
| 100,000 | EUR 200 | ~EUR 0.002 |
| 500,000 | EUR 500 | ~EUR 0.001 |
| 1,000,000 | EUR 650 | ~EUR 0.00065 |
At scale, Captain Verify is dirt cheap for pure verification - under a tenth of a cent per email at the 1M tier. If all you need is deliverability checks, nothing in this comparison beats it on price. (If you're comparing verifiers, see email verification options too.)
SalesQL
SalesQL bundles finding and verification credits on monthly or annual plans:
| Plan | Monthly | Annual | Credits/mo (Monthly) | Credits/mo (Annual) |
|---|---|---|---|---|
| Free | $0 | - | 100 | - |
| Basic | $39 | $29/mo | 2,000 | 24,000 |
| Professional | $79 | $59/mo | 5,000 | 60,000 |
| Organization | $119 | $89/mo | 12,000 | 144,000 |
Annual plans include dramatically higher credit allocations. Basic annual gets 24,000 credits/month versus 2,000 on monthly billing. That's a 12x difference, making annual the obvious choice if you're committed. One note: SalesQL updated its plan structure, so if you're on a legacy plan, switching or canceling means you can't go back.
Feature-by-Feature Comparison
| Category | Captain Verify | SalesQL | Prospeo |
|---|---|---|---|
| Primary function | Email verification | Email finding | Finding + verification |
| Best for | List cleaning | Prospecting | Both workflows |
| Free tier | 100 verifications on signup | 100 credits/month | 75 emails + 100 ext credits/mo |
| Pricing model | Pay-per-batch | Monthly subscription | Credit-based, ~$0.01/email |
| Built-in verification | Core feature | Secondary feature | 98% accuracy |
| Built-in finding | No | Yes | Yes, 300M+ profiles |
| Data refresh cycle | N/A (verifies on demand) | Not disclosed | 7 days |
| Integrations | API | HubSpot, Salesforce, Zapier, Make, API | Salesforce, HubSpot, Clay + 7 more |
Running Captain Verify plus SalesQL means two dashboards, two billing cycles, and zero shared data between them. That friction adds up fast. If you're building a broader stack, compare outbound lead generation tools and SDR tools before you commit.
What If You Need Both?
Here's the thing: most teams shopping this comparison don't actually need both tools. They need one that does both jobs. In our experience, running two separate platforms creates more friction than anyone expects, and the credits never line up when you need them.
Let's be honest - the whole "find emails in one tool, verify in another, export CSV, re-import" workflow is a time sink that feels like 2019. Prospeo handles this by combining 300M+ professional profiles with 30+ search filters and real-time verification on every result. Their proprietary email-finding infrastructure doesn't rely on third-party providers, which is why teams like Snyk saw bounce rates drop from 35-40% to under 5% after switching. The free tier gives you 75 verified emails and 100 Chrome extension credits per month, and paid plans run about $0.01/email with no contracts. (If deliverability is the real pain, start with an email deliverability guide and email bounce rate benchmarks.)
Snyk's 50 AEs dropped bounce rates from 35-40% to under 5% after switching to Prospeo - because every email is verified at the moment of discovery. At ~$0.01/email with a 7-day data refresh, you get fresher contacts than SalesQL and built-in verification that outperforms Captain Verify.
Ditch the two-tool workflow. Find, verify, and export in one click.
FAQ
Can I use Captain Verify and SalesQL together?
Yes. Use SalesQL to find emails, export to CSV, then run them through Captain Verify's bulk verifier. It works, but you're managing two tools and two billing cycles. A combined platform handles both steps in one workflow at roughly the same cost.
Does SalesQL verify emails?
SalesQL bundles a built-in verifier with separate credit pools - 100 verification credits on Free, then 5,000 to 20,000 depending on your plan. For high-volume campaigns where you need bounce rates below 3-4%, a dedicated verifier or a platform with proprietary verification infrastructure will catch more edge cases.
Is Captain Verify GDPR compliant?
Captain Verify runs servers in France with ISO 27001 and SOC certification - a strong baseline for EU data residency. One Capterra reviewer flagged a concern about being added to a mailing list after signing up. Review their data processing terms before committing at scale.
