Span Global Services vs. Apollo.io
Apollo’s own reviews tell two different stories. Here’s what each one is actually about, and what it means for your data.
Both ratings are real. They’re just measuring different things.
A Fair Analysis to Help You Choose Your Data Partner
Apollo.io is not really a like-for-like competitor to a data provider. It’s an all-in-one go-to-market platform that bundles a contact database with sequencing, a dialer, enrichment, and CRM sync. That bundle has earned it a strong following: 4.7 out of 5 on G2 from roughly 9,500 reviews, most of them praising the workflow, the search filters, and the price-to-feature ratio for smaller teams.
But look at Trustpilot, and the picture shifts: independent aggregators reviewing the same company put it at roughly 2.9 out of 5 from over 1,000 reviews, with billing disputes, account issues, and data-quality complaints doing most of the damage. Both ratings are real. They’re just measuring different things.
This page is about that gap: what’s actually behind it, and what it means if accurate, send-ready contact data is the thing you actually need.
We’re not arguing Apollo is a bad product. The G2 number alone makes that a hard case to make, and we’re not going to pretend otherwise.
The more useful question for you is narrower: is Apollo’s data the reason you’d recommend it, or is the platform doing the heavy lifting while the data quietly costs you bounce rate and sender reputation?
Here’s what its own reviews say.
The Mixed Feedback, and What It Really Tells You
What G2 Ratings Measure
G2 ratings often reflect how useful a platform feels overall. Since Apollo combines multiple sales functions into one tool, many users rate it positively for convenience, even when they may have concerns about areas like data accuracy, customer support, and bounce-rate commitment.
What Trustpilot Reviews Measure
Trustpilot reviews, on the other hand, are more likely to come from customers reporting a specific problem, such as billing issues, suspended accounts, or email lists with high bounce rates.
Apollo’s ratings across both platforms follow this pattern: the platform itself is highly rated, while its data quality and billing practices receive more criticism and mixed feedback.
So instead of asking “Is Apollo good or bad?”, the more useful question for a buyer is: which of these two ratings is actually measuring the part of Apollo I’m about to pay for?
Where Span Does It Differently
Every contact we deliver passes through automated screening and then a human tele-verification pass, including phone numbers, which are called to confirm they reach the actual person, not just a company switchboard.
That’s our claim, and like any vendor’s claim, including one with a thin review base, it deserves scrutiny rather than blind trust. Our team ensures a bounce-rate commitment, and we’ll show you exactly how each record is validated and verified.

What the Reviews Say Once You Look Past the Average
Across G2, Capterra, Trustpilot and independent review analyses, a handful of specific, recurring issues show up consistently enough to be worth addressing directly to decision-makers rather than averaging away.
Bounce Rates Are Above What’s Advertised
Multiple independent review analyses report real-world bounce rates of 15 to 35% on exported Apollo contacts, depending on industry and geography, notably higher than the accuracy figures Apollo advertises.
One frequently cited pattern: a batch of “verified” contacts coming back with an 18% hard-bounce rate on day one, plus another quarter returning “no longer at company” replies, leaving less than half the list actually usable by the time a campaign finishes.
15 to 35% reported real-world bounce rateG2 ReviewThe reviewer calls data accuracy “the biggest frustration,” citing bounce rates higher than expected and roughly 10 to 15% of contacts with outdated information.
A Steep International Data Gap
Apollo’s coverage is strongest in the US, Canada, and UK, where independent estimates put accuracy around 85 to 90%. That figure drops to roughly 75 to 85% in Western Europe, and multiple G2 reviewers report accuracy falling to somewhere between 50% and 70% in APAC, LATAM, and Eastern Europe, with outdated job titles and invalid phone numbers as the most commonly cited problems in those regions.

Mobile Numbers That Don’t Reach the Person
Direct-dial accuracy is reported at roughly 50 to 70%, and it’s one of the most consistent complaints across G2 and Capterra: numbers flagged as verified frequently connect to a company’s main switchboard rather than the actual contact, after the credit for that lookup has already been spent.
50 to 70% reported direct-dial accuracyTrustpilot ReviewThe reviewer says Apollo’s data was reportedly 30% inaccurate and that they were unable to reach a live person for support.
A Credit System That Adds Friction as You Scale
Apollo charges users in credits for contact lookups, but not every lookup costs the same number of credits. Mobile number lookups can cost several times more than email lookups. This means that when a mobile number turns out to be wrong or simply connects to a company switchboard, you still lose the higher number of credits spent on that lookup.
Independent pricing breakdowns also point out that Apollo has reduced the number of credits available on its free tier over time, while its highest paid plan requires a minimum of three seats, meaning you may have to pay for three seats even when only one person needs access.
A Documented Data-Sourcing Complaint
Among Apollo’s Trustpilot reviews, at least one details a contact saying their personal email address was added to Apollo’s database without their consent or an opt-in. Apart from data accuracy issues, this is also an important consideration for companies that prioritize consent-based sourcing and compliance.
The Other Side of the Ledger
Apollo has satisfied users who highlight accurate data, efficient workflows, and the time saved by having multiple sales tools in one platform. The concerns above are not presented to suggest Apollo is “broken”; rather, they reflect specific issues reported by customers across other review platforms. A fair evaluation should consider both the overall satisfaction score and the recurring data quality concerns revealed through broader customer feedback.
Ask Us About Our Customers’ Real Results
Span Global Services is building a stronger library of real customer journeys and case studies that showcase the results businesses have achieved using our data. As these stories take time to document and publish, they may not yet be fully reflected on our website. In the meantime, you can speak directly with our representatives to learn about real campaign results, measurable outcomes, and the impact our data has delivered.
Why Bundling Data With Your Outreach Tool Can Hide the Real Problem
When your contact data and sending platform are part of the same subscription, a bounced email is simply recorded as “a bounce.” This can make it difficult to determine whether the problem comes from the contact data itself or from other factors such as your subject line, sending domain, or send timing.
That’s arguably part of why Apollo’s data-accuracy complaints coexist so comfortably with a 4.7 rating on G2: reviewers are largely scoring the workflow, and list quality gets absorbed into “how Apollo works” rather than showing up as its own, separately accountable line item.
Separating your data source from your sending tool does the opposite. It puts list quality somewhere you can actually see it, test it, and hold a single vendor accountable for it, independent of your domain reputation, your template, or your send schedule.
That’s the case for sourcing your contact data from a dedicated provider rather than the same platform you send from: not because the platform is bad, but because bundling the two makes it harder to tell which one is actually responsible when a campaign underperforms.
Don’t Take Our Word for It, Check the Sample
With a specific, well-documented bounce-rate range already on the record for Apollo, a same-conditions test is the fastest way to see whether that gap actually shows up in your own target list.

- A validation step you can actually see, including phone numbers. Every contact passes through automated screening and then a human tele-verification pass, and we’ll take care of what gets rejected and why.
- A bounce-rate commitment defined in plain language before you sign, not an average rating that blends software satisfaction with data quality.
- No forced seat or volume minimums that lock you into paying for capacity you don’t use.
- Consistent validation regardless of region, rather than a data set that’s strong in North America and considerably weaker elsewhere.
- A free sample list you can test against your current numbers before you commit to anything, so the decision is based on your own data, not our word for it.
- A named account contact and a stated replacement turnaround, so a bad batch of records is a fixable problem, without worrying about a credit you’ve already spent.
Why Teams Choose Span as Their Apollo Data Alternative
The case for Span isn’t “Apollo is bad.” It’s that the two products are optimized for different things, and it’s worth being deliberate about which one you’re actually buying data from. Here’s what we hear most from teams making this call.
Commitments That Go Beyond Data Delivery

We provide data quality commitments based on the engagement model. Bounce-rate guarantees are available for managed campaigns where campaign factors such as sender reputation and domain health can be controlled.
Flexible Volume Requirements
Standard data programs may include minimum volume commitments, while custom and white-label projects are designed with flexible volume structures based on customer requirements.
Replacement Support for Inaccurate Records
We provide replacement contacts for inaccurate records to help customers maintain reliable and usable prospect databases.
Campaign Optimization Support
Our managed campaign services and dedicated customer success representatives help customers improve campaign execution, targeting, and overall outreach performance.
Customer References When Applicable
Prospects can review available testimonials and customer experiences, with direct references possible when approved and not restricted by confidentiality agreements.
Proven Results Through Case Studies
We share anonymized and named case studies (where permitted) to demonstrate real-world applications and campaign outcomes.
Compliance-Focused Data Practices
Our data processes align with regulations and standards including GDPR, CCPA, DPDP, and enterprise compliance frameworks such as ISO and HIPAA where applicable. Read our data security policy.
None of this is a claim that Span is flawless, or that Apollo is a bad vendor. Its available reviews are mostly positive, and we’re citing that honestly rather than cherry-picking.
What it does show is how we’ve built an all-inclusive process that addresses the documented gaps and gives you greater visibility into areas you may not be able to verify independently when a vendor has a mixed public track record. We also invite you to test our data against your own list before taking our word for it.

Why Teams Are Comparing Span Global Services With Apollo, and How It Helps You
“Data quality” means something different depending on what you’re using Apollo for. Here’s what we hear most often from teams weighing Span alongside it.
You’re Already Noticing Bounce or Accuracy Issues With Apollo’s Data
If your exported lists are bouncing at a rate that’s hurting sender reputation, that’s a data problem, not a workflow problem, and it’s worth sourcing your contacts from a provider whose entire job is getting that number right, rather than a feature inside a bigger platform.
You’re Prospecting Outside North America
Apollo’s reported accuracy drops meaningfully outside the US, Canada, and UK, and international teams are exactly where the documented data gap shows up hardest. This is where human, per-record verification and the global coverage of Span Global Services data matter most, regardless of the region you’re targeting.
You’re Hitting Apollo’s Credit Ceiling as You Scale
Once mobile lookups and export volume climb, the credit system and its 3-seat minimum on top tiers start showing up as a real line item. Teams in this spot often find a quote-based model from SGS, priced against the list they actually need, easier to plan around.
What Switching Can Look Like
The two examples below are composites, built to show the kind of outcome teams typically report after moving their contact data to a verified data provider that puts opt-in lists first.
Moving Off a Bounce-Heavy List Before It Cost Them Their Domain
- Profile
- A mid-market SaaS sales team sourcing target lists from Apollo’s database ahead of a renewal-quarter outbound push.
- The Problem
- Their last quarterly export bounced at roughly 22%, within the 15 to 35% range widely reported for Apollo-sourced lists, and the resulting spam-complaint volume began denting their domain’s sender score right before the campaign that mattered most.
- The Switch
- They requested a free sample list from Span filtered to their next target segment, and moved their sourcing to Span once the difference was clear.
- The Typical Outcome
- Teams in this position typically see bounce rates fall from the 20%+ range into the mid-single digits, alongside a measurable recovery in sender and domain reputation score within one to two sending cycles.
Closing the Accuracy Gap Outside North America
- Profile
- A revenue team expanding outbound into Western Europe and APAC after building initial US pipeline in Apollo.
- The Problem
- Non-US segments performed noticeably worse than domestic ones, consistent with the roughly 50 to 70% accuracy reported for Apollo’s APAC and Eastern Europe coverage, with a high share of credits spent on numbers that reached a switchboard rather than the named contact.
- The Switch
- They requested a human-verified list from Span for the specific regions they were expanding into, rather than relying on Apollo’s broader global database for those markets.
- The Typical Outcome
- Teams in this position typically report accuracy on non-US segments moving into the high 80s to low 90s, with a materially higher connect rate on direct-dial numbers and fewer credits wasted on dead lookups.
On Pricing
Credit-Based, Per Seat
Apollo’s credit-based pricing is public: a free tier, then paid tiers commonly reported around $49 to $149 per user per month depending on billing terms, with the top tier requiring a three-seat minimum before you send a single email.
Quoted Against Your Actual List
Span doesn’t publish a rate card; pricing is quoted against your actual target list, with a bounce-rate guarantee included as part of that quote. A custom list tailored to your needs means you pay for the contacts you’ll actually use.
If your Apollo costs are climbing due to mobile-credit consumption or seat minimums, it’s worth quoting the same volume against a per-contact model to see which works out cheaper for your use case.
Frequently Asked Questions
Span Global Services vs. Apollo.io: What’s the Core Difference?
Apollo optimizes for volume and speed at a low entry price. Span Global Services optimizes for verified accuracy, provides a custom list, and takes care of the opt-in process.
Which Has Better International Data Coverage?
Apollo’s accuracy is strong in the US (around 85 to 90%) but drops to roughly 50 to 70% outside North America, since it has no fallback source when a record is stale. Span Global Services is built around verification across regions, not just US-first coverage.
Which Has More Reliable Phone and Mobile Numbers?
Apollo’s direct-dial accuracy is estimated at 50 to 70%, with numbers often routing to a switchboard instead of the named contact. Span verifies numbers by phone before they’re added to a record.
How Do the Pricing Models Compare?
Apollo charges by credits, so a bad lookup still costs you. Span Global Services uses a net-new model, so you only pay for contacts you don’t already have.
Which Is Better for Early-Stage Teams vs. Scaling Teams?
Apollo is a reasonable fit for small teams testing outbound on a budget. Span Global Services fits teams that have hit accuracy pain (bounces, bad numbers, weak international reply rates) and need reliability over rock-bottom cost.
Do I Have to Switch Entirely, or Can I Test First?
No full switch is needed upfront. Request a sample list from Span against your next Apollo export and compare bounce and connect rates directly.
Is Span’s Data Actually More Accurate Than Apollo’s?
We believe our human tele-verification step closes the specific gaps documented above, particularly on phone numbers and international coverage, but you shouldn’t take our word for it any more than you’d take a vendor’s advertised accuracy figure at face value. Run the side-by-side test described earlier on a live sample from your own target list; it’s the only comparison that reflects your actual use case.
