ZoomInfo is the most comprehensive B2B contact database - but at $15K-$100K+/year, it’s priced for enterprise. Here are 7 alternatives that cover most use cases at a fraction of the cost, with a guide to which one fits your team.
$15K-$100K+/year
ZoomInfo is enterprise-priced. For teams under 10 SDRs, 80-90% of contact quality is achievable at 10-20% of the cost via Apollo or Cognism.
Locked annual contracts
ZoomInfo requires annual commitment with aggressive renewal tactics. Apollo and Hunter offer monthly billing with no lock-in.
Thin EU data
ZoomInfo’s EU contact coverage and GDPR compliance are weaker than Cognism, which is purpose-built for European B2B outreach.
275M+ contacts, 73M companies. Built-in sequencer, CRM sync, intent signals, A/B testing. Free tier is genuinely useful. Replaces ZoomInfo for most SMB and mid-market teams at 10-20% of the cost. Weaker on technographics and org charts vs. ZoomInfo.
400M+ contacts. Diamond-verified mobile numbers scrubbed against EU Do-Not-Call registers. Comparable price to ZoomInfo at entry level, but purpose-built for EU GTM teams. Much stronger GDPR compliance than ZoomInfo.
If intent data and technographic filtering are the main ZoomInfo use case, SalesIntel provides similar signals at lower cost. Contact coverage is US-centric. Less comprehensive than ZoomInfo on volume but cheaper for intent-specific targeting.
Domain-based email finder with accuracy guarantee. No intent data, no org charts, no mobile numbers. Replaces only the ‘find email addresses’ part of ZoomInfo at a fraction of the cost - excellent for teams that just need emails.
LinkedIn Chrome extension that enriches profiles with direct email + mobile. Strong EU/UK coverage. GDPR-compliant. Replaces ZoomInfo for teams whose primary workflow is LinkedIn profile enrichment rather than bulk database export.
Credit-based mobile and email finder with Chrome extension. Less data depth than ZoomInfo but much cheaper for teams that need occasional lookups rather than bulk export. Available as self-serve with transparent pricing.
Enrichment workflow tool: combine 50+ data sources (including ZoomInfo data via waterfall), AI personalisation, CRM enrichment. Not a replacement for ZoomInfo’s raw database - a smarter way to use multiple cheaper data sources together.

ZoomInfo, Apollo, Cognism, and every other B2B data tool indexes contact information at a point in time. B2B email data decays at ~2% per month as people change jobs, companies fold, and domains expire. “Verified” in any platform means the address was valid when they last checked - which could be months ago. Run your exports through BounceZero before loading into your sequencer to catch addresses that have decayed since indexing.
For most teams: Apollo.io (US outbound, free tier, $49/user/month) covers 80-90% of ZoomInfo’s use case at 10% of the cost. For EU/UK outreach: Cognism (GDPR-compliant, verified mobiles). For email-only: Hunter or FindyMail. For enrichment workflows: Clay. ZoomInfo is still unmatched for breadth of US intent data and technographics at enterprise scale.
ZoomInfo is custom-quoted and annual-only. Entry level for 3-5 users typically $15K-$25K/year. Larger enterprise deployments with intent data, technographics, and advanced integrations run $40K-$100K+/year. Apollo starts at $49/user/month with no annual lock-in required.
ZoomInfo is worth it for enterprise GTM teams who need the broadest US database, intent data, technographics, and org charts at scale. For small teams doing primarily email outbound, Apollo or Cognism provide most of the value at a fraction of the cost. The deciding factors are whether you need intent/technographic data, and whether your team will fully utilise the platform breadth.
Every B2B data tool’s accuracy degrades over time. BounceZero’s live SMTP verification catches stale addresses that no database keeps current. $3/1K. 100 free credits.
