Before you cut over

  • Set up single sign-on in ZoomInfo before you invite the team, so accounts are created through your identity provider rather than by hand.
  • If you restrict Apollo.io to office or VPN IP addresses today, check how you will enforce the same rule in ZoomInfo; we found no IP allowlisting documented.

B2B SALES OUTREACH · MIGRATION GUIDE

Switching from Apollo.io to ZoomInfo

Moving from Apollo.io to ZoomInfo means treating it as a database swap: there’s no named migration tool, so contact lists move via CSV export/import while sequences and enrichment rules get rebuilt from scratch in ZoomInfo’s engagement tools.

Quick verdict: Makes sense for larger sales orgs that need ZoomInfo’s deeper firmographic/intent data and are willing to pay enterprise pricing and sign a contract – overkill for smaller teams who were using Apollo mainly for prospecting plus lightweight sequencing.

Why teams switch from Apollo.io to ZoomInfo

Larger, more frequently verified contact database

ZoomInfo is widely regarded as having a larger and more frequently refreshed B2B contact and company database than Apollo, particularly for enterprise firmographic and org-chart data.

Intent data and buying signals

ZoomInfo’s intent and website-visitor identification products give revenue teams signals Apollo doesn’t offer natively at the same depth.

Built for enterprise revenue operations

ZoomInfo’s platform is designed around enterprise RevOps workflows – territory/account mapping, org charts, and integrations with enterprise CRMs – that go beyond what Apollo’s SMB-friendly toolset targets.

How to migrate your data

There’s no official Apollo-to-ZoomInfo import tool, so plan this as a manual data migration plus a from-scratch sequence rebuild.

StepWhat happens
1Export your Apollo contact and company listsExport the saved lists, contacts, and accounts you want to keep from Apollo as CSV files.
2Clean and dedupe the exportRemove duplicates and stale records before import, since ZoomInfo will re-enrich and may flag conflicting data against its own database.
3Import lists into ZoomInfoUpload your cleaned CSVs into ZoomInfo’s contact/list manager, mapping fields to ZoomInfo’s schema.
4Rebuild sequences in ZoomInfo EngageManually recreate your Apollo email sequences and call cadences as new sequences in ZoomInfo’s engagement tooling, since sequence steps and templates don’t transfer.
5Reconnect your CRM and enrichment syncRe-point your CRM sync (Salesforce, HubSpot) to ZoomInfo and configure enrichment rules that mirror what Apollo was doing automatically.
6Re-verify sender domains for outbound sequencingIf you’re using ZoomInfo for outbound email sequencing, reconnect and re-verify your sending mailboxes, since deliverability setup does not carry over from Apollo.
What ZoomInfo’s importer doesn’t handle: Sequences, email templates, call scripts, and enrichment/scoring rules do not transfer between Apollo and ZoomInfo in either direction – only raw contact and company records move via CSV, and everything else must be manually rebuilt.

Pricing during the transition

Apollo publishes self-serve per-user pricing while ZoomInfo is quote-only and publishes no prices.

PlanApollo.ioZoomInfo
Free plan$0 (Apollo Free, limited credits)No free plan – quote-only
Entry paid tierBasic $49/user/month billed annually (Apollo)Not published – custom quote only
Mid tierProfessional $79/user/month billed annually (Apollo)Not published – custom quote only

ZoomInfo does not publish list pricing and requires a sales conversation for any quote, so no ZoomInfo prices are shown above (as of September 2026).

Feature-parity checklist

Both platforms combine a contact database with outbound sequencing, but they’re built for different company sizes and budgets.

Frequently Asked Questions

Is there an official Apollo-to-ZoomInfo migration tool?

No – neither vendor publishes a named importer for the other; migrating means exporting contacts as CSV and rebuilding sequences manually.

Will my Apollo sequences transfer to ZoomInfo?

No, sequence steps, templates, and cadences need to be manually recreated in ZoomInfo’s engagement tools.

How much does ZoomInfo actually cost?

ZoomInfo doesn’t publish pricing – you’ll need to go through a sales call, and third-party reports suggest entry packages commonly start in the low five figures annually.

Do I need to re-verify my data after importing into ZoomInfo?

Yes – ZoomInfo will re-enrich imported contacts against its own database, which can surface conflicting or updated firmographic data you’ll want to review.

Is switching from Apollo to ZoomInfo worth the cost increase?

Only if you specifically need ZoomInfo’s larger database, intent data, or enterprise RevOps features – many SMB teams find Apollo sufficient at a fraction of the cost.
