Prospeo vs SalesQL: Which B2B Email Finder Is Worth Your Money?

Prospeo vs SalesQL: Which B2B Email Finder Is Worth Your Money?

Most "vs" articles pretend both tools are roughly equal. This one won't - the numbers aren't close. SDRs already spend 68% of their time on non-selling activities, and picking the wrong data tool makes that worse. We couldn't find a direct Prospeo vs SalesQL comparison anywhere online, so we built one from scratch.

30-Second Verdict

Prospeo wins on data accuracy (98% vs 70-80% email retrieval), database size (300M+ profiles vs 89M direct + 127M work emails), mobile coverage (125M+ verified mobiles vs 30M phones), and features (intent data, 7-day refresh, API). SalesQL is a cheaper entry point on annual billing ($29/mo) for solo prospectors who mainly need a browser extension. For anything at scale, Prospeo is the clear choice.

Both Tools at a Glance

Prospeo is a full B2B data platform: 300M+ profiles, 143M+ verified emails, 125M+ verified mobiles, intent data across 15,000 topics, and a 7-day data refresh cycle. It covers database search with 30+ filters, enrichment returning 50+ data points per contact, API access, a Chrome extension, and native integrations with Salesforce, HubSpot, Smartlead, Instantly, Lemlist, Clay, Zapier, Make, and more.

SalesQL is an extension-first email finder built around professional profiles. Its database covers 89M direct emails, 127M work emails, and 30M phone numbers. It's popular with recruiters and solo prospectors who live inside their browser, and it supports workflows across various professional networking platforms. The workflow is dead simple: visit a profile, grab the email, export to CSV. SalesQL holds a 4.5/5 on G2 from 166 reviews, with users praising ease of use.

Feature-by-Feature Comparison

One important distinction before the table: SalesQL reports "retrieval rate" (the percentage of profiles where an email is found), while Prospeo reports "accuracy" (the percentage of found emails that are actually valid). Retrieval without accuracy just means more bounces.

Data Quality and Accuracy

This is where the real gap shows up.

Prospeo runs a 5-step verification process with catch-all handling, spam-trap removal, and honeypot filtering on proprietary infrastructure. The result: 98% email accuracy and a 30% mobile pickup rate across regions. We've seen this hold up in practice - Snyk's 50 AEs cut bounce rates from 35-40% to under 5% after switching, generating 200+ new opportunities per month.

SalesQL retrieves emails for 70-80% of profiles, but that's a retrieval rate, not a deliverability rate. Its email verifier checks format validity, MX/server status, and mailbox status without sending an email, but it doesn't describe catch-all handling, spam-trap removal, or honeypot filtering as part of its verification methodology. G2 reviewers commonly flag outdated data as a pain point, alongside limited credits and poor customer support.

There's also an operational risk worth knowing about. SalesQL's help center highlights that profile view limits are the key constraint: roughly ~200/day on basic accounts, ~500/day on premium accounts, and ~1,000/day on recruiter-tier accounts. Push past those limits and you risk account restrictions. SalesQL recommends mitigation tactics like staying within limits and using CSV enrichment to work off-platform - which somewhat defeats the purpose of an extension-first tool.

Here's the thing: at 50 contacts a month, a 10-15% bounce rate is annoying. At 500 or 5,000 contacts a month, it's domain reputation damage that takes weeks to recover from. Prospeo's 7-day refresh cycle means you're working with current data. SalesQL doesn't publish a refresh cadence at all.

Pricing Breakdown

SalesQL's pricing page breaks down like this:

One SalesQL finding credit gets you work emails, direct emails, and phone numbers for one profile. You're paying for profile credits, and SalesQL's own benchmark is that it retrieves emails for about 70-80% of profiles - so roughly 20-30% of your credits return nothing useful. SalesQL also lists a "Campaigns" feature as coming soon, but it isn't live yet.

One more thing: if you're on a legacy SalesQL plan and cancel or switch, you can't go back. Older pricing in Reddit threads or reviews won't be available to you.

Prospeo starts free (75 emails + 100 Chrome extension credits/month), with paid plans from $49/mo for 2,000 credits at roughly $0.01 per verified email. No contracts, cancel anytime. You pay for verified results, not attempts.

Who Should Pick Which

Pick SalesQL if you're a solo recruiter or SDR who lives entirely inside a browser extension and wants a simple workflow. Reddit's recruiting community describes it as cheap and effective for exactly this use case. Skip it if you're running outbound for a team of more than two or three people.

Pick Prospeo if you're running outbound at any real scale, need verified mobiles, care about deliverability, want intent data to prioritize warm prospects, or need API/enrichment workflows. The 98% accuracy and 7-day refresh aren't nice-to-haves - they're what keep your domain off blocklists.

Let's be honest about the economics. If your average deal size is under $5K and you're emailing fewer than 100 people a month, SalesQL's free tier is fine. But the moment you scale past that - and most teams do within a quarter - the cost of bad data in bounced emails and burned domains dwarfs the price difference. In our experience, teams that switch from budget tools to Prospeo see bounce rates drop by 80%+ almost immediately, which is exactly what happened with Snyk and Meritt.

FAQ

Is SalesQL accurate enough for cold email?

SalesQL retrieves emails for 70-80% of profiles but doesn't publish a deliverability rate. At scale, expect higher bounce rates than Prospeo's 98% verified accuracy - Snyk saw bounces drop from 35-40% to under 5% after switching. If you're testing SalesQL beyond 200 contacts/month, monitor your bounces closely and be ready to pull the plug fast.

Does SalesQL offer intent data?

No. SalesQL focuses on contact extraction from professional profiles. Prospeo tracks 15,000 intent topics via Bombora, letting you prioritize prospects actively researching solutions like yours - a fundamentally different approach to prospecting that means you're not just finding people, you're finding people who are ready to buy.

Can I try both tools for free?

Yes. SalesQL offers 100 free credits per month. Prospeo offers 75 free emails plus 100 Chrome extension credits per month. Neither requires a credit card, so you can run a side-by-side test with zero risk.
