ContactOut vs Apollo.io: Which One Actually Delivers?
Apollo.io gives you a full outbound platform - sequences, dialer, CRM sync, and a credit-based data engine - in one seat license. ContactOut gives you a Chrome extension that pulls personal emails for recruiting better than almost anything else. Comparing these two means understanding they solve different problems, and picking the wrong one wastes months.
We've spent real time inside both tools, and here's the thing: the right choice depends less on features and more on what you're actually trying to do every day.
30-Second Verdict
Apollo.io if you need sequences, a dialer, and CRM sync in one platform for outbound sales at scale.
ContactOut if you're a recruiter who needs personal emails, ATS integrations (Gem, Greenhouse), and simplicity over feature depth.

Apollo.io - The All-in-One Bet
Apollo is the everything platform for outbound. A 275M+ contact database, multi-step sequences, built-in dialer, A/B testing on higher tiers, and CRM integrations - all from one login. For sales teams consolidating their stack, it's the obvious starting point.
The data quality problem is real, though. Apollo carries 503 "Inaccurate Data" and 458 "Data Inaccuracy" tags on G2 - the two most common complaints across those 9,512 reviews. One practitioner test on Reddit reported ~65% usable contacts after verification. Unlimited email credits don't help when roughly a third bounce.
Credits expire at the end of the billing cycle, overages can bill automatically, and you can't reduce seats mid-term. Two companies on the same plan can see different limits depending on when they migrated to Apollo's new credit system - a quirk nobody else is telling you about.
Wins: All-in-one platform, strong filters, fast list building. Stings: Data accuracy varies by region, credit expiration, steep learning curve (474 G2 tags for that specific complaint).
ContactOut - Built for Recruiters
A recruiter on r/Recruitment switched from Apollo to ContactOut specifically for stronger personal email coverage, lower bounce rates, and faster support. That's the story in a nutshell.
It's a Chrome extension that surfaces personal and work emails from professional profiles and company websites, with a search portal for bulk prospecting. Personal email coverage is genuinely stronger than Apollo's - 150M vs 75M - and integrations with Gem and Greenhouse make it a natural fit for talent teams. The free plan only works with standard professional profiles, not Recruiter or Sales Navigator editions.
The catch is credit limits. The $79/mo Sales (Email) plan caps you at 300 exports per month. An SDR doing serious prospecting burns through that in two days. And ContactOut's pricing page showing "Talk to us" placeholders in 2026 is a transparency red flag for what's essentially a self-serve Chrome extension. Let's be honest - if you can't show me what something costs, I'm already skeptical.
Apollo gives you ~65% usable contacts. ContactOut caps you at 300 exports/month. Prospeo delivers 98% email accuracy from 300M+ profiles, refreshed every 7 days - not every 6 weeks. At $0.01 per email, a 5-seat team spends less than either tool while sending with confidence.
Stop verifying bad data. Start with data that's already verified.
Accuracy and Data Quality
Neither tool solves the core problem: you still need to verify data before you use it.
Apollo's ~65% accuracy in that Reddit test meant 6 hours of work - 2 hours building lists, 4 hours verifying - for 500 accounts. ContactOut markets "99% confidence," but G2 reviewers still flag outdated contacts and inactive numbers. Teams that skip real-time verification often see 20-30% bounce rates regardless of what the marketing page promises.
Here's our frustration with both: if your bounce rate is above 5%, the problem isn't which tool you picked. It's that you're treating unverified data as ready-to-send. We've seen teams at Prospeo cut bounce rates from 35% to under 4% simply by switching to a 7-day data refresh cycle - the industry average is six weeks, and that gap explains most deliverability problems. (If you want benchmarks and fixes, start with bounce rate and the full deliverability guide.)
Pricing Breakdown
Apollo.io
| Plan | Annual | Monthly |
|---|---|---|
| Free | $0 | $0 |
| Basic | $49/user/mo | $59/user/mo |
| Professional | $79/user/mo | $99/user/mo |
| Organization | $119/user/mo (min 3) | $149/user/mo (min 3) |
A 5-seat Professional plan runs ~$4,740/year on annual billing - before overages. Mobile data and exports are credit-gated.
ContactOut
ContactOut's official pricing page isn't consistently transparent (it often renders as "Talk to us"), so most teams rely on plan limits shown in third-party pricing grids plus ContactOut's own "starts at $29/mo" FAQ.
| Plan | Price (Annual) | Key Limits |
|---|---|---|
| Free | $0 | 10 credits/month |
| Sales (Email) | $79/mo | ~2K emails/month, 300 exports/month |
| Email + Phone | $99/mo | ~2K emails/month + ~1K phones/month, 600 exports/month |
| Recruiters | $199/mo | 12K emails/year |
| Team / API | Custom | Quote-based |
At $79/mo with 300 exports, you're paying $0.26 per export. ContactOut's comparison page mentions plans "starting at $29/mo," though that tier doesn't appear on the main pricing page.
What Real Users Say
Apollo's G2 review volume (9,512) dwarfs ContactOut's (109), so direct comparison is lopsided. The signal is clear though: Apollo users praise filters and workflow automation, then flag data accuracy as the top complaint. ContactOut users praise ease of use, then complain about credit limits and outdated contacts.
On Reddit, a cold email practitioner evaluated both and stuck with ContactOut for cost-effectiveness on prospecting. The consensus on r/coldemail leans toward stacking a cheaper data source with a separate sending tool rather than paying Apollo's premium for an all-in-one you only half-use. Recruiters gravitate toward ContactOut for personal emails; sales teams gravitate toward Apollo for the platform.
If you're building a modern outbound stack, it also helps to compare categories: SDR tools, outbound lead generation tools, and sales prospecting techniques.
When Neither Tool Is Enough
If you're exporting contacts from either tool and spending hours verifying them, you're solving the wrong problem.
For teams that need data quality without the platform lock-in of Apollo or the credit constraints of ContactOut, that's the cleaner path.
ContactOut charges $0.26 per export. Apollo's unlimited credits mean nothing at 65% accuracy. Prospeo gives you 143M+ verified emails, 125M+ verified mobiles with a 30% pickup rate, and 30+ search filters - no credit expiration, no 'talk to us' pricing walls.
Replace both tools with one that actually delivers clean data.
FAQ
Is ContactOut more accurate than Apollo.io?
ContactOut delivers better personal email coverage for recruiting workflows, claiming 150M personal emails versus Apollo's 75M. Apollo publishes a 95% accuracy claim, but practitioner testing reported ~65% usable contacts after verification. Neither eliminates the need for post-export verification - Prospeo's 98% accuracy with a 7-day refresh cycle is a stronger option for teams prioritizing deliverability.
Which is cheaper for outbound prospecting?
ContactOut starts at $29/mo versus Apollo's $49/user/mo on annual billing, but Apollo includes sequences and a dialer. Apollo's credits expire each billing cycle with potential automatic overages; ContactOut caps exports at 300-600/month. At scale, Prospeo at ~$0.01/email often costs less than either - and you skip the verification step entirely.
Can I use ContactOut and Apollo.io together?
Yes - some teams use ContactOut for personal emails in recruiting and Apollo for work emails and outbound sequences. If you're stacking tools, consider whether a single higher-accuracy provider would be simpler and cheaper than maintaining two platforms plus a separate verification layer.
