The answer up front: this is a 10-20x price decision before it is a data decision. Apollo is self-serve and published: free tier, then $49-119 per user/month billed annually, cancel monthly if you pay monthly. ZoomInfo publishes no prices: reported floors start near $15,000/year, the median buyer pays about $33,500/year (Vendr marketplace data across 1,571 purchases), contracts are annual-only, and its auto-renewal notice windows are the single most documented complaint in the category. Buy ZoomInfo when you genuinely need its direct-dial coverage, org charts and intent depth at enterprise scale. Buy Apollo when you need a capable database plus sequencing at self-serve prices. And if the list was always a means to replies, there is a third question worth asking - at the end.
Disclosure: this comparison is published by Valley, which does not sell a contact database but does compete for outbound budget. Every figure below is dated September 7, 2026 and labeled confirmed (vendor's own page) or reported (named third party), so you can check us line by line.
Valley is an AI outbound platform that finds the people most likely to buy from you - from live buying signals, natural-language search, or your own lists - qualifies them against your ICP, researches each one, and sends personalized messages across email and LinkedIn that get 15-45% reply rates, against a category average of about 2%.

Head to head, on what is verifiable
Apollo | ZoomInfo | |
|---|---|---|
Published pricing | Yes: Free / $49 / $79 / $119 per user/mo annual (about $59/$99/$149 monthly, tracker-reported); Organization needs 3 seats | No. Reported floors ~$15,000/yr; median actual spend ~$33,500/yr (Vendr, 1,571 purchases); real all-in commonly $30-60K with add-ons |
Contract | Monthly available, cancel anytime, free tier | Annual-only, ~3-seat minimum, auto-renewal standard |
Database claim | 240M+ people, 30M+ companies (their comparison page; other Apollo pages say 210-275M depending on vintage) | 500M contacts, 135M+ verified phones, 120M+ direct dials (their data page; third parties note these are cumulative profiles) |
Accuracy claim vs reported reality | Claims 98% email accuracy; independent roundups report ~65-80%, with 15-25% bounce reports on "verified" contacts in r/coldemail threads | Claims up to 95%; independent testing roundups report ~75-85% |
What is bundled | Sequences, dialer (US on Pro), buying-intent topics, CRM integrations - a work platform, not just data | Org charts, technographics, Scoops, WebSights, intent built on trillions of keyword pairings - the deepest firmographic layer sold |
The metering | Email credits effectively unlimited (fair-use capped); mobile credits (75-200/mo) run out first and drive upsells; credits burn even on stale records (documented complaint) | Credit packages by tier; overages, intent add-ons ($5-15K reported) and international data (~$10K reported) are where quotes grow |
Reviews | G2 4.7/5 (~9,600 reviews) vs Trustpilot 2.9/5 (~1,050) - the gap is billing/suspension complaints | G2 4.5/5 (~8,900 on the sales product) vs Trustpilot 1.7/5 (~320, acknowledged on ZoomInfo's own reviews page) |
The contract clause that decides more deals than the data
ZoomInfo agreements typically require 60-90 days written notice before renewal - and the notice window can close 60 days before term end. Miss it and you own another year, often with a built-in 5-10% escalator (Vendr documents the escalation clauses; Lead411 and LeadGenius maintain detailed write-ups, and those write-ups reference a class-action complaint over the auto-renewal practices - reported, not independently verified by us). None of this makes the data worse; it makes the calendar reminder part of the total cost of ownership. Apollo's equivalent risk is different: its Trustpilot cluster is billing disputes and account suspensions, worth reading before you load a card.
The decision, by scenario
Under ~50 employees, or any team without procurement: Apollo, and it is not close. The $0 and $49 tiers answer the question for free, and even ZoomInfo reviewers flag it as poor value for teams selling to small companies.
Enterprise motion that lives on direct dials, org charts and account intelligence: ZoomInfo, negotiated hard. Anchor on Vendr's $33,500 median (buyers reportedly save ~22% off initial quotes), cap the escalator, and calendar the notice window the day you sign.
Either way, price the credits, not the seats: Apollo's mobile credits and ZoomInfo's add-ons are where the real bill lives. Our deep dives: Apollo pricing and credits · ZoomInfo pricing explained · ZoomInfo alternatives for small teams.
The third question
Both tools answer "who could we contact?" Neither answers "who is likely to reply this week?" - which is the number outbound actually lives on. A static list, however accurate, tells you nothing about timing; the people most likely to answer are the ones already circling you: viewing profiles, engaging posts, following competitors, hiring, raising. That is the lane Valley works: live buying signals pick the prospects (or bring your own Apollo/ZoomInfo export - CSV import is native), qualification discards bad fits, 200+ sources of research feed a message in your voice across LinkedIn and email, and you approve every send. 15-45% reply rates against a ~2% category average, methodology published in our benchmarks report. $149/month billed quarterly, 7-day free trial.

How to choose in 30 seconds
No procurement team: Apollo. Enterprise data needs and a negotiator: ZoomInfo, with the renewal window on a calendar. Replies this week rather than records this quarter: signals, not lists - the alternatives tree covers all three paths.
FAQ
Is ZoomInfo worth it over Apollo? Only when its exclusive assets - direct-dial coverage, org charts, deep intent - map to your motion at enterprise scale. Reported median spend is ~$33,500/year against Apollo's $588-1,428 per user; the delta buys a lot of elsewhere.
What does ZoomInfo actually cost? Unpublished. Credible reported figures (September 7, 2026): floors near $15,000/year, median ~$33,500 (Vendr, 1,571 purchases), $30-60K all-in with add-ons common. Every figure is negotiable; buyers reportedly average ~22% off initial quotes.
How many seats does Apollo's Organization plan require? Three, at $119/user/month billed annually - Apollo's own comparison page confirms 3, though older write-ups still say 5.
Why are both vendors' Trustpilot scores so much worse than their G2 scores? Different populations: G2 skews active, invited users; Trustpilot collects the billing and cancellation disputes. Apollo sits at 2.9 there (~1,050 reviews) and ZoomInfo at 1.7 (~320) - read both before signing anything annual.
Can Valley replace Apollo or ZoomInfo? Not as a database - Valley is not a contact-data vendor. It replaces the workflow after the list: signal-based selection, qualification, research, and writing across LinkedIn and email. Many customers pipe an Apollo export into Valley via CSV.
