SalesQL vs Apollo.io: Honest Comparison (2026)
You've got budget for one data tool, your SDRs want emails that don't bounce, and you're staring at two tabs: SalesQL and Apollo.io. Here's the honest breakdown so you can stop second-guessing and start prospecting.
30-Second Verdict
Apollo wins if you need prospecting and sequencing in one platform. SalesQL wins if you live on professional profiles and just need fast, per-profile enrichment at a predictable credit cost.
On G2, Apollo holds a 4.7/5 from 9,515 reviews versus SalesQL's 4.5/5 from 166. Apollo's rating is far more battle-tested - SalesQL's smaller review base means a handful of outliers can swing the score.
Side-by-Side Feature Comparison
| Feature | SalesQL | Apollo.io |
|---|---|---|
| G2 Rating | 4.5/5 (166 reviews) | 4.7/5 (9,515 reviews) |
| Starting Price | $0/mo (free tier) | $0/mo (free tier) |
| Paid Plans | $39 / $79 / $119 per month | ~$49 / $79 / $119 per user/month |
| Credits/Month | 2,000 / 5,000 / 12,000 | Per-action credits (expire monthly) |
| Free Plan Limits | 100 credits/month | Unlimited email credits; 5 mobile + 10 export/mo |
| Credit System | 1 credit per profile (charged when at least one email is found) | Per-action credits |
| Seats Included | Basic: 1 / Pro: 3 / Org: 15 | Per-user (Organization plan typically requires 3+ seats) |
| Best For | Profile enrichment | All-in-one prospecting |
G2 sub-scores tell a useful story. SalesQL edges Apollo on Ease of Use (9.1 vs 9.0), but Apollo leads on Meets Requirements (9.1 vs 8.7) and Product Direction (9.4 vs 8.5). Worth flagging: SalesQL's Capterra Customer Service score sits at 3.3, which is a genuine red flag if you ever need help troubleshooting.
What You'll Actually Pay
SalesQL's pricing is straightforward. Monthly plans run $39, $79, or $119. Annual billing drops those to $29, $59, and $89. One credit equals one profile lookup, and you're only charged when at least one email comes back.
Apollo looks similar on paper, but per-user pricing changes the math fast. A 5-person team on Professional at ~$79/user/month runs ~$395/mo before you even factor in credit consumption for reveals, exports, and mobile lookups. Credits expire monthly and don't roll over.
Here's the thing: the decision isn't the sticker price - it's cost per usable contact. SalesQL's Basic tier gives you 2,000 profiles at $39/mo. If 80-95% are usable, that's roughly $0.02-$0.024 per contact. Apollo can be great value when the data hits, but the consensus on r/sales and r/LeadGeneration is that real-world Apollo email accuracy lands around 65-70%, which pushes your cost per deliverable email up fast if you're exporting and blasting without verification. If you're comparing options, it also helps to benchmark against other sales prospecting databases and free lead generation tools.
Apollo's real-world accuracy lands around 65-70%. SalesQL's ranges from 50% to 95% depending on the profile. Prospeo delivers 98% email accuracy through a proprietary 5-step verification process - and refreshes every 7 days, not monthly.
Stop paying for emails that bounce. Pay $0.01 for ones that land.
How Accurate Is the Data?
Stop obsessing over database size. The only number that matters is how many contacts you can actually message.
A third-party test of 1,000 Apollo contacts run through ZeroBounce found 93.2% valid, 4.1% invalid, and 2.7% catch-all. Solid on paper. But practitioners on Reddit consistently report real-world accuracy closer to 65-70% - the gap comes from data decay, role changes, and catch-all domains that pass verification but still bounce.
SalesQL's accuracy varies wildly. On Capterra, one recruiter ran 300+ emails and got just 13 undeliverable - genuinely strong. Another reviewer called it "works 50% of the time." That spread tells you accuracy depends heavily on which profiles you're targeting and how fresh the underlying data is.
Let's be honest: if your deals average under $15k, neither tool's accuracy is good enough to send raw. We've seen teams cut bounce rates in half just by adding a verification layer before anything hits a sequence. If you're trying to keep bounces under control, use an email deliverability guide and track your email bounce rate as a first-class metric.
Workflow Fit
Use Apollo if you want prospecting, filtering, and email sequencing in one platform. The search interface is genuinely good - it's one of the better list-building experiences we've tested. Skip Apollo if you need reliable send timing. Users on Reddit report 2-3 hour gaps in scheduled sequences, and the suggested workaround of running multiple email accounts isn't a real solution.
Use SalesQL if you're a recruiter or sourcer who lives on professional profiles. Its Chrome extension is the most-praised feature on G2 - users highlight speed and simplicity for grabbing contact info mid-browse. Skip SalesQL if you need CRM depth. There's no bidirectional Salesforce sync, which means manual copy-pasting at volume. For a growing sales team, that's a dealbreaker - especially if you're standardizing your stack around an SDR tool or planning to connect outreach tool to CRM.
When Neither Tool Is Enough
Both tools source data. Neither specializes in making sure that data is actually deliverable when it hits your sequences.
That's where Prospeo fits. With 98% email accuracy and a 7-day data refresh cycle, it catches the stale records that monthly-refresh tools miss. A proprietary 5-step verification process - including catch-all handling, spam-trap removal, and honeypot filtering - fills the accuracy gap that both SalesQL and Apollo leave open. The model is self-serve with transparent pricing at ~$0.01 per email, and a free tier lets you test before committing. It works as a standalone prospecting platform or as a verification layer on top of whatever you're already using. If you're evaluating the broader category, compare against other data enrichment services and email search tools.
Both SalesQL and Apollo charge credits that expire monthly - and neither guarantees the data is deliverable when it hits your sequence. Prospeo gives you 300M+ profiles with 98% verified accuracy, catch-all handling, and spam-trap removal built in.
Replace the verification layer you're bolting on. Prospeo has it built in.
FAQ
Do SalesQL credits roll over?
No. Credits renew each billing cycle and unused ones expire. If you're on a legacy plan, your terms stay active until you cancel or switch, but you can't return to old pricing once you leave.
Why does Apollo pricing feel unpredictable?
Apollo charges per user plus usage-based credits for reveals, exports, and mobile lookups - all of which expire monthly. The credit system has changed over time, and legacy accounts often have different limits than new signups. That's why two teams on the "same" plan describe completely different bills.
What's a good alternative if neither tool fits?
Prospeo is worth testing if accuracy is your top priority. It delivers 98% verified email accuracy at ~$0.01/email with a 7-day data refresh - significantly fresher than either SalesQL or Apollo. The free tier (75 emails/month) lets you benchmark it against your current tool without commitment.
Can I add a verification step to either tool?
Yes - and you should. Running exports through a dedicated verification layer before sequencing catches job changes and stale records that damage sender reputation. Teams that add this step typically report bounce rates dropping below 4%, which is the threshold most deliverability experts consider safe for sustained outbound.
