Apollo vs ZoomInfo: Data Accuracy, Coverage, and Cost Compared

The Apollo vs ZoomInfo choice turns on channel and budget: pick Apollo if your team is email-first and spends under about $10,000 a year on data; pick ZoomInfo if you sell by phone into enterprise accounts and can sign a five-figure annual contract. In Drevon's 100-account test the two were close on accuracy: ZoomInfo had 78% role accuracy and Apollo 74%. ZoomInfo found more direct dials. Apollo costs a fraction as much: a five-seat Professional team pays $4,740 a year at list, against a $33,500 ZoomInfo median.

How do Apollo and ZoomInfo compare at a glance?

Apollo is a self-serve database with sequencing built in; ZoomInfo is an enterprise data platform sold on annual contracts. Here is the side-by-side, as of October 2026.

	Apollo	ZoomInfo
Published pricing	Yes	No, quote only
Entry paid price	$49 per seat a month, annual ($65 monthly)	About $15,000 a year (third-party estimates; ZoomInfo publishes no list price)
Typical spend	$4,740 a year for 5 Professional seats at list	Median $33,500 a year (Vendr, 1,576 purchases)
Credit model	Shared pool; email 1 credit, phone 8	1 credit per contact or company export
Credits included	30,000 to 72,000 per seat per year	About 5,000 a year on entry packages (third-party)
Database claim	240M contacts, 30M companies	420M+ contacts, 120M+ direct dials, 145M+ companies
Role accuracy, Drevon test	74% (26 of 100 titles outdated)	78% (22 of 100 no longer in role)
Company coverage, Drevon test	98 of 100 target companies	Not reported separately
Direct dials, Drevon test	Not reported separately	71 of 100
Contract	Monthly or annual; monthly cancels at term end	Order-form term; not cancellable; auto-renew reported
Sequencing and dialer	Included	Dialing included; automated outreach workflows from Copilot Advanced
Best for	SMB and mid-market email outbound	Enterprise phone-led sales, intent-driven ABM

Vendor database claims are self-reported and counted differently, so do not compare them directly. The test figures come from Drevon's 100-lead test of sales intelligence tools, which covered mid-market and enterprise tech companies in cloud infrastructure, security and fintech.

Which has more accurate data, Apollo or ZoomInfo?

ZoomInfo was slightly more accurate on job titles in our test, 78% against Apollo's 74%, but both left roughly one contact in four or five pointing at the wrong person. The test checked returned titles against live company rosters and primary web profiles.

That gap is small next to the shared problem. If 22 to 26 of every 100 contacts have moved on, both tools need a verification step before outreach. People change jobs continuously, as we cover in why B2B data decays by over 30% a year.

For Apollo emails specifically, BounceZero, an email verification vendor, checked 100,000 Apollo contacts exported in the first half of 2026. It found 73.2% valid, 18.4% catch-all and 5.8% invalid. We found no comparable independent email study for ZoomInfo.

ZoomInfo puts an accuracy promise in its contract. Its public License Terms say that if more than 5% of licensed contacts are not employed at the listed company, you can notify ZoomInfo. It then has 30 days to reach 95% accuracy, or you may terminate with a prorated refund.

Neither tool's intent data links back to a source you can inspect. Our test noted that Apollo's intent relies on third-party content consumption surges and that ZoomInfo's intent does not link to the original web discussions.

Which has better coverage?

Apollo found contacts at more companies; ZoomInfo found more phone numbers. In the test, Apollo returned candidate profiles at 98 of the 100 target companies. ZoomInfo returned 71 direct phone numbers, the highest direct-dial match of the five tools tested.

The vendors' own numbers point the same way. Apollo advertises access to 240M contacts and 30M companies. ZoomInfo's sales page claims 420M+ global contacts, 120M+ direct dials and 145M+ companies.

Coverage matters most where you sell. Salesgear notes that independent tests suggest lower Apollo accuracy outside North America. ZoomInfo's about page claims 34M+ companies and 200M+ professionals outside North America. If you sell mainly in Europe or Asia, run a 50-account sample of your real territory through both trials before you commit.

How much does each cost?

Apollo costs $49 to $119 per seat a month on annual billing with prices on its website; ZoomInfo is quoted, with a median contract of $33,500 a year.

Take a five-rep outbound team:

	Apollo Professional (annual)	ZoomInfo (median)
Annual cost	5 x $79 x 12 = $4,740	$33,500
Data included	240,000 credits	Not published; entry packages about 5,000 credits
Cost per email reveal	$0.0198	About $3.00 per export at a $14,995 / 5,000-credit list price
Cost per phone reveal	8 credits = $0.158	Same 1 credit per export

The ZoomInfo per-export figure divides the whole contract by credits, so it includes seats and software. It still shows the scale of the difference. ZoomInfo costs about 7x as much as Apollo for this team, and the extra spend buys direct dials, intent and enterprise support.

The comparison flips only when phone numbers dominate your usage. Two pricing details favour ZoomInfo for phone-heavy teams. On Apollo a phone number costs 8 credits, against 1 for an email. On ZoomInfo every export is one credit, whatever fields it includes. A rep who calls every lead pays Apollo 9 credits per contact, which cuts a Professional seat's 48,000 yearly credits to about 5,333 email-and-phone contacts.

How do contracts and flexibility differ?

Apollo lets you start monthly and cancel at the end of the term; ZoomInfo locks you into the term on your order form. Apollo's FAQ says monthly plans can be cancelled anytime, effective at the end of the current term, and that annual plans cannot be downgraded mid-cycle.

ZoomInfo's License Terms state that the agreement "is not cancellable" and runs for the term in the Ordering Document. Cognism and Coffee, both competitors, report that standard contracts auto-renew for 12 months unless you give written notice 60 days before renewal. Your own order form sets the actual notice period, so check it on the day you sign. They also report renewal increases of 5% to 20%.

Credits behave differently too. Apollo credits are pooled across the team and expire at the end of each billing cycle. Third parties report that ZoomInfo credits also do not roll over.

Data rights after you leave also differ. Our analysis of where your prospect data goes compares what each vendor lets you keep.

How should you test Apollo and ZoomInfo before you buy?

Run the same sample through both trials and score it on your own accounts, not on vendor claims. Apollo has a free plan and a 14-day trial on Basic and Professional. ZoomInfo offers free trials on most plans. A one-week bake-off is enough.

1. Pick 50 target accounts from your real territory, mixing sizes and regions.
2. Choose two buyer roles per account, so you are looking for 100 contacts.
3. Pull those contacts from each tool and export them to a sheet.
4. Check each title against the person's current LinkedIn profile or company team page.
5. Run every email through the same verifier and record valid, catch-all and invalid.
6. Have one rep call 20 numbers from each tool and log who answers.
7. Divide the annual quote by the number of contacts that passed all three checks.

The last step gives you a cost per usable contact for your market, which beats any published benchmark. Keep the sheet: it is also your evidence in the ZoomInfo negotiation.

Who should pick Apollo, and who should pick ZoomInfo?

Apollo is the better default for most teams under 20 reps. ZoomInfo is the better buy only when direct dials and intent data change your win rate enough to cover a five-figure contract.

Choose Apollo if:

• You are a founder, small team or mid-market team with an email-first motion.
• You want published prices, monthly billing and a free plan to test.
• You want sequencing, dialer and data in one seat.
• You will add your own verification step anyway.

Choose ZoomInfo if:

• Your reps call more than they email and need direct dials at scale.
• You sell to enterprise accounts where intent topics and buying-group data shape territory plans.
• You have procurement capacity to negotiate seats, credits and renewal terms.
• Marketing will use the same data for ABM, which ZoomInfo sells as separate plans.

If neither fits, a waterfall tool may. Clay combines many providers and charges nothing for misses; see Clay vs ZoomInfo and Clay pricing. For more options, see our roundup of 15 prospecting tools.

What do Apollo and ZoomInfo both miss?

Both tell you who works where; neither tells you why an account should hear from you this week. The best signals are posts, hiring pages and public discussions, which we list in nine buying signals you can't get from a contact database.

That is the job Drevon does. It reads LinkedIn, Reddit, Sales Navigator, job boards and company sites in your own browser and returns a brief where every claim links to its source. Teams run it before they spend database credits, then export the accounts that show real signals to Clay, HubSpot or their sequencer.
