Apollo.io review: contact data, pricing and what sales teams get
By Jan Suski, six years working in digital. How the scoring works.
This Apollo.io review covers what the platform does, how accurate its contact data is, what the free plan and paid plans cost, and how Apollo compares with the alternatives sales teams weigh it against. Apollo.io is a B2B sales intelligence and engagement platform, founded in 2015 and headquartered in San Francisco.
Co-founder Tim Zheng now serves as chairman after the company appointed Matt Curl as chief executive officer in February 2026, a promotion from chief operating officer rather than an outside hire; Curl had run the company day to day for roughly two years before the title changed.
What is Apollo.io
Apollo.io combines prospecting, outreach and analytics into one sales platform, an approach the company markets as replacing five separate point tools with a unified platform that sales teams and marketing teams can share. Apollo integrates with major CRMs including Salesforce and HubSpot, so a sales rep working a lead list doesn't have to leave an existing workflow to log a call or update a deal stage.
The platform runs on a credit-based system: contact data, verified contacts and enrichment pulls consume credits, and mobile credits are billed separately from email and general search credits. Apollo.io uses that credit system to gate certain features rather than charging a flat rate for unlimited pulls, which shapes how sales teams budget for the platform once free-plan limits run out.
Contact database and contact data accuracy
Apollo.io's contact database holds 275 million contacts and 73 million companies, the scale that makes it a default starting point for sales reps building a lead list from scratch. Apollo offers more than 65 advanced filters for lead targeting, letting a sales rep narrow that contact database by job title, company size, industry and dozens of other fields before exporting a list.
Apollo's data quality
Apollo.io claims 97% email accuracy, a figure it has published against a 230 million-contact base that predates the current 275 million count, so the headline percentage and the headline database size come from different vintages. G2 reviews score Apollo.io's data accuracy at 8.3 out of 10, a solid but imperfect mark among sales intelligence platforms. Apollo processes more than 270 million records monthly to support that data reliability claim, refreshing records rather than leaving a static database to go stale.
Real-world data accuracy tells a more mixed story than the headline number. Users report data accuracy inconsistencies, especially outside North America, and Apollo's data quality varies by region in ways the 97% figure doesn't fully capture.
Apollo's single-source enrichment limits data coverage to 40 to 60%, well short of the coverage a buyer gets from a provider that blends multiple third party providers into each contact record.
Sales reps working accounts in Europe or Asia should expect more manual cleanup of contact data than reps working purely North American accounts, and should treat the accuracy figure as a US-weighted average rather than a global constant.
Finding leads: search, filters and lead lists
Apollo data covers 275 million contacts and 73 million companies, and the search experience is built around turning that raw apollo data into usable lead lists rather than a flat export. A rep can find leads by job title, company size, industry, location and dozens of other fields, then save the results as lead lists that sync directly into a sequence, cutting out the export-and-reimport step that slows down a manual sales process.
Company data sits alongside the contact-level fields: firmographic details like revenue range, employee count and technology stack let a rep filter beyond a job title to the kind of company websites and business profile that match an ideal customer profile. Data enrichment runs in the background on saved lists, refreshing verified contacts and flagging past interactions so a rep working a list a second time isn't starting from a stale snapshot.
That enrichment layer is also where accurate contact data matters most: a lead list built on outdated titles or old company websites wastes a sales rep's time before the first call ever happens, and accurate contact data is the difference between a list that converts and one that bounces. International data coverage lags the platform's US and Canada numbers, a gap that shows up most for sales teams building prospect lists outside North America.
Free plan and paid plans
Apollo.io's pricing starts at $0 a month for a free plan, a generous one by sales intelligence platform standards: free users get real access to the core contact database and basic search rather than a crippled trial. The free plan is why Apollo.io is considered valuable for SMBs and startups that need contact data and lead generation tools without committing to a paid plan on day one.
| Plan | Price | Notes |
|---|---|---|
| Free | $0 a month | Core contact database, basic search, lower credit and sequence limits |
| Professional | $79 per user/month billed annually | Team of five: $395 a month combined |
| Organization | $119 per user/month billed annually | Shared reporting, admin controls, unlimited sequences |
Across every plan price tier, unused credits expire at the end of each billing period rather than rolling over, so a sales team that buys a plan sized for peak usage ends up paying for credits it never spends in a slower month.
Intent data and buyer intent signals
Apollo's intent data and buyer intent signals aim to tell a sales rep who a prospect is and when that prospect is actively in-market. Intent signals draw on website visitors, website visits and other buying-intent behavior, layered with intent filters so a rep can build a lead list of accounts already showing buyer intent rather than cold-calling a static list.
Visitor identification is part of that same buyer intent picture: Apollo can flag which companies' employees are visiting a customer's website, tying anonymous website visitors back to named contacts already in Apollo's database. That combination of intent data and visitor identification is meant to help sales reps engage leads earlier in a buying cycle, before a prospect fills out a contact form.
Lead generation and engagement tools
Apollo.io offers multi-channel email sequencing and engagement, letting a sales rep or marketing team combine email, calls and tasks into a single outreach sequence rather than juggling separate tools for each channel. Apollo automates outreach with built-in email sequencing and task reminders, and includes automated lead scoring and AI-generated email support to help a rep draft a first-touch email faster.
AI assisted email writing in Apollo.io drafts a starting point rather than a finished message; most reps still edit the ai generated emails before sending, particularly for accounts with buyer intent signals worth a more personalized outreach effort. Apollo's search filters allow detailed prospect targeting that feeds directly into those sequences, so a rep can go from finding leads to launching an outreach effort without exporting a list to a separate tool, a workflow that replaces manual tasks many users used to handle in a spreadsheet.
The Chrome extension is a meaningful part of that lead-generation workflow: Apollo.io's Chrome extension allows users to extract contact information from LinkedIn directly into a lead list, skipping a manual copy-paste step that used to eat up a sales rep's morning. Engagement tools built around that extension let a rep move from finding a prospect on LinkedIn to adding them to a sequence in a few clicks.
International dialer and parallel dialer
Apollo's phone dialer and parallel dialer round out the sales engagement side of the platform. The parallel dialer lets a rep call multiple phone numbers at once and connects the call only when a live person picks up, a feature built to cut the dead time between calls that a manual dialer wastes. The international dialer extends that same calling infrastructure to mobile numbers and landlines outside the United States, letting sales teams running global sales and marketing motions call international prospects from inside the same platform.
Phone calls placed through Apollo consume mobile credits separately from email credits, and heavy dialer usage during a peak window, like the start of a sales quarter, can burn through a plan's mobile credits faster than lighter email-only outreach.
Sales engagement across calls, email and tasks is the design goal behind the whole apollo platform, and the Organization plan's unlimited sequences give larger sales and marketing teams room to run that sales engagement without hitting a cap mid-quarter. That structure is built around allowing sales reps to work a full sequence, calls included, without switching tools between each channel.
Data accuracy, deliverability and customer support
Apollo's email deliverability is affected by shared sending infrastructure: because many Apollo customers send from infrastructure the platform manages, one customer's poor sender reputation can indirectly affect deliverability for others on the same shared infrastructure.
Email deliverability best practices still apply when using Apollo.io: warming up a sending domain, avoiding spammy language and pacing sequence sends all still matter, since the platform doesn't guarantee inbox placement on its own.
Users have noted that Apollo's performance can slow during high-volume usage, particularly when a large sales team runs simultaneous sequences and dialer sessions during the same busy period. On the support side, Apollo.io's customer support rating is 4.2 out of 5 on Capterra. Apollo offers priority email support for paying customers only, while Apollo also provides 24/7 AI chat support for all users, including those still on the free plan.
Reviewers describe the support team in contradictory terms: some call the staff responsive and knowledgeable, while others report slow ticket response times during busier periods.
CRM integration and tech stack
Apollo integrates with major CRMs like Salesforce and HubSpot through two-way sync, pushing contact data, sequence activity and call logs back into a company's existing tech stack rather than living as an island. CRM integration is generally reliable for standard fields, though some users report sync delays between Apollo and a connected CRM during high-volume import periods, and custom fields sometimes require manual cleanup after a large data import.
For sales teams and marketing teams running a broader tech stack, Apollo also connects to marketing automation tools and data warehouses, letting intent signals and buyer intent data flow into systems beyond the CRM itself. That tech stack flexibility is one reason Apollo shows up in both sales-led and marketing-led go-to-market motions rather than staying purely a sales tool.
Analytics dashboards let a manager track performance across a full sales team rather than pulling reports from each rep's individual sequences, one of the advanced features that separates the Professional and Organization plans from a stripped-down basic plan elsewhere in the category. A tool that ships only a basic plan tends to leave that kind of team-wide reporting out entirely.
Who Apollo.io fits and who it doesn't
A small sales team with a handful of reps can get real value from Apollo's no-cost tier alone: enough apollo data to find leads and build a first sequence without a budget line item. Once that team starts paying for a higher tier, the return depends on volume, since the platform's real strength is letting one rep run outreach efforts that would otherwise require three separate point tools, contact sourcing, sequencing and dialing, stitched together by hand.
Larger revenue teams get a different kind of value out of the same apollo data: shared visibility across reps, manager-level reporting, and enough phone numbers and mobile credits pooled across a team that no single rep runs dry mid-quarter. That's also where data enrichment pays off most, since a shared contact database only stays useful if records get refreshed as people change jobs and companies change phone numbers.
Marketing teams sit slightly outside that core use case but increasingly show up as Apollo customers anyway, mainly for the website visitors data. Tying anonymous website visitors to named contacts already sitting in Apollo's database gives a marketing team a way to find leads before those leads ever fill out a form, then hand them to sales already enriched. Teams that don't need that combination, and just want a narrow, well-built email tool, are usually better served by a lighter dedicated cold email tool than by paying for Apollo's full feature set.
Apollo's learning curve
The platform has a steep learning curve for new users, a recurring theme in Apollo.io reviews. Between advanced filters, sequence building, the dialer, intent data and CRM integration settings, a new rep can take weeks to use the platform at full capacity rather than just running basic searches.
Apollo's own onboarding resources and the AI chat support help flatten that learning curve, but sales leaders rolling Apollo out to a full sales team should budget real training time rather than expecting reps to self-teach the advanced features on day one.
Apollo.io alternatives and biggest competitors
Four names come up repeatedly against Apollo, and each wins on a different axis.
| Alternative | Where it beats Apollo |
|---|---|
| ZoomInfo | Enterprise account intelligence and intent programmes, at a higher price |
| Cognism | European data and GDPR posture; phone-verified mobiles at a claimed 98% accuracy |
| Clay | Waterfall enrichment across 150+ providers; custom workflows |
| Lusha | Simplicity and time-to-first-contact |
ZoomInfo is the enterprise incumbent, stronger on account-based marketing and intent-driven programmes and priced accordingly; comparisons routinely put Apollo at a fraction of ZoomInfo's cost, which is why Apollo dominates the SMB and startup end while ZoomInfo holds the large-enterprise end. Cognism is the answer for teams selling into Europe, where Apollo's coverage is weakest: its phone-verified Diamond Data mobile numbers carry a claimed 98% accuracy and its GDPR posture is built for European prospecting rather than retrofitted to it.
Clay takes a different approach entirely, waterfalling requests across 150-plus data providers and letting technical go-to-market teams build custom enrichment workflows, which directly addresses the single-source coverage limit that caps Apollo at 40 to 60%. Lusha competes on simplicity and speed rather than depth, aimed at teams that want contact data quickly without learning a platform.
The right alternative usually depends on which gap matters most to a team: data coverage, European compliance, deliverability infrastructure, or dialer functionality, since few competitors match Apollo on all of prospecting, sequencing and calling at once. A team whose only complaint is Apollo's international data should price Cognism or Clay before abandoning the platform, because the sequencing and dialer layers are what a narrower tool won't replace.
Frequently asked questions
What features does Apollo have?
Apollo combines a 275 million-contact database, more than 65 advanced filters, multi-channel email sequencing, an AI-assisted email writer, a parallel dialer and international dialer, visitor identification, buyer intent signals, and CRM integration with Salesforce and HubSpot into one sales platform.
Why was Apollo shut down?
Apollo.io has not shut down. The platform remains active with a generous free plan and paid plans, and it appointed Matt Curl as CEO in February 2026 while co-founder Tim Zheng continues as chairman, a leadership change rather than a shutdown.
Is Apollo.io still good?
Apollo.io remains a widely used sales intelligence platform, with G2 reviewers scoring its data accuracy at 8.3 out of 10 and Capterra reviewers scoring customer support at 4.2 out of 5. Its main limitations are a steep learning curve and data accuracy that varies by region.
Is Apollo.io not free anymore?
Apollo.io still offers a free plan starting at $0 a month with access to its core contact database and basic search. Paid plans, including the Professional plan at $79 per user per month and the Organization plan at $119 per user per month, unlock advanced filters, larger credit allowances and the dialer.
How much is Apollo IO per month?
The Professional plan costs $79 per user per month billed annually, so a team of five pays $395 a month. The Organization plan costs $119 per user per month billed annually. Both sit above the $0 free plan, which covers core contact records and basic search.
Can I get Apollo for free?
Yes. Apollo.io's free plan costs $0 a month and includes access to the contact database and basic search, though free users have lower credit limits and sequence limits than paying customers on the Professional or Organization plan.
Who is Apollo's biggest competitor?
ZoomInfo, on the enterprise side, where its account-based marketing and intent tooling compete directly with Apollo at a considerably higher price. Cognism, Clay and Lusha are the other three names that come up most, competing on European data, enrichment waterfalls and simplicity respectively.
Is there something better than Apollo?
Better depends on the gap. Cognism beats Apollo on European contact data and GDPR posture; Clay beats it on enrichment coverage by waterfalling across 150-plus providers; ZoomInfo beats it on enterprise account intelligence; Lusha beats it on time-to-first-contact. None of the four matches Apollo on combining prospecting, sequencing and dialing in a single platform with a free tier underneath.
What can I use instead of Apollo?
ZoomInfo for enterprise data depth, Cognism for European prospecting, Clay for custom enrichment workflows, and Lusha for straightforward contact lookups. Dedicated cold-email specialists are the alternative for teams whose only requirement is deliverability and sequencing.
Is Apollo.io reliable?
Apollo.io is reliable for its core use case, contact data and outreach automation, with G2 reviewers rating data accuracy at 8.3 out of 10. Reliability drops for accounts outside North America, where Apollo's data quality and coverage are weaker than the headline accuracy figure suggests.
Is Apollo trustworthy?
Apollo is a legitimate, actively maintained sales platform used by large sales teams rather than a scam or an abandoned product. Its main trust gap is data accuracy variance by region rather than any question about the company's legitimacy.
How much does Apollo.io cost per month?
Cost ranges from $0 a month on the free plan to $79 per user per month on the Professional tier and $119 per user per month on the top tier, both billed annually, with mobile credits and other usage-based costs layered on top depending on dialer and enrichment usage.
What does the Apollo.io do?
Apollo.io functions as a combined prospecting and engagement platform: it finds leads through its contact database and advanced filters, engages leads through email sequencing, an AI-assisted email writer and a phone dialer, and tracks performance through analytics dashboards, all integrated with a company's CRM.
Is Apollo.io free with no catch?
The free plan costs $0 a month without requiring a credit card that auto-converts to a paid plan, though users on the free tier face lower credit limits, sequence caps and feature access than customers on a paid plan.
What is Apollo by Palantir?
Apollo.io is not affiliated with Palantir Technologies. The confusion usually stems from Palantir's own internal deployment platform, which Palantir also calls Apollo, an unrelated product built for managing Palantir's own software releases rather than for sales prospecting.
Can I use Apollo.io on my phone?
Apollo.io's dialer features, including the parallel dialer and international dialer, are built around placing calls to mobile numbers, and the platform supports mobile access for reps managing sequences and calls away from a desktop.
Is Apollo.io legitimate?
Yes. Apollo.io is a legitimate, established sales platform with a large customer base, transparent published pricing for its plans, and an active support team, unlike a fly-by-night data broker.
Does Apollo AI work?
Apollo's AI features, including AI-generated emails and automated lead scoring, work well enough to draft a usable starting point for outreach, though most sales reps still edit AI-generated emails before sending rather than relying on them unedited, particularly for accounts flagged with strong buyer intent signals.
