Independent users treat Apollo as the budget default: far cheaper than ZoomInfo, with data and sequencing bundled in one place, and good enough for US prospecting if you accept extra cleanup. The recurring complaint is data freshness: users describe stale records, people who left years ago, wrong or switchboard phone numbers and bounce rates that stay high even after Apollo's own verification, plus renewals and credit changes that raised costs. About 40% of the Reddit mentions read as promotional, including a large, coordinated cluster of near-identical comments pitching Prospeo as the Apollo replacement, so this rests on roughly 30 independent opinions.
Users like
- Costs a fraction of ZoomInfo, and users who weigh price against quality call the data good enough for the money[1][2][3][4][5]
- Several users who had both Apollo and ZoomInfo preferred Apollo overall[1][2][3]
- Database, sequencing and dialing live in one tool, which users find simple for early-stage or low-volume outbound[1][2][3]
- Works without major issues for some users, particularly when targeting the US[1][2][3]
Users complain about
- Stale records: users find people who left months or years ago (one found a contact who died 20 years earlier still listed), with bounce rates around 9% even after running lists through a verifier[1][2][3][4][5]
- Phone numbers are a weak spot: inactive, wrong-person or HQ switchboard numbers returned instead of no result, and one user reports half the numbers were unreliable[1][2][3][4]
- Costs have crept up: a long-time customer's renewal tripled after a credit system change, and others say enrichment is expensive for what it returns[1][2][3]
- Coverage thins outside the US and in some niches: it lost to ZoomInfo and Cognism in one team's US and EMEA test, and a health tech team found it missed many people after leaving ZoomInfo[1][2][3]
About 18 first-hand, non-promotional comments, many from recruiters, give a mixed but mostly favourable picture: ContactOut is rated for personal emails and for pulling contacts from LinkedIn profiles, while several senders report that not every email is verified and bounces follow, and views on its phone numbers are split. Promotion is heavy: the corpus filter already dropped 81 repeat-promoter comments, an Apollo employee called out astroturfing for ContactOut in one r/coldemail thread where several accounts praised it within days in February 2026, a September and October 2025 burst of 'tried it, tech team was great' testimonials was excluded, and many criticisms came only inside pitches for Prospeo, FullEnrich and other tools, so those are not counted either.
Users like
- Strong on personal email addresses; a tech recruiter who tried it alongside RocketReach found it the stronger of the two for personal emails[1][2]
- Works well for LinkedIn-sourced lists; one user who has used a dozen data tools says it stands out across almost every vertical when starting from LinkedIn[1][2][3]
- Email accuracy is rated well by some users, including one team reporting under 2% bounces on LinkedIn-sourced lists[1][2]
- Helps recruiters find hard-to-reach passive candidates[1]
Users complain about
- Not every email it returns is verified; several users report bounces and say results need a separate verification pass[1][2][3]
- Phone coverage was poor for SaaS contacts in one user's experience, and another found its numbers less accurate than ZoomInfo's (other users rate its mobiles well)[1][2]
- Has grown from a lookup tool into a broader sales platform; a user who only needed LinkedIn lookups found it overkill and left, and another barely used it because the interface was confusing[1][2]
- You are locked into its credit-based pricing model, which one user cites as a reason to build their own sourcing instead[1]
