Apollo.io vs ZoomInfo

Most startups and small sales teams should pick Apollo.io. It combines a B2B contact database with email sequences and calling, has a free plan, and you can buy it with a card today. Pick ZoomInfo when you're a larger revenue org that needs intent data, ABM and enrichment workflows across teams, and you're ready for a negotiated contract.

Pick Apollo.io if

• You want prospecting data and outreach sequences in one tool instead of two.
• You're a founder or small team that needs to start for free or on a monthly plan.
• You want published per-seat prices you can budget without a sales call.
• Your reps run their own outbound and need contacts, sequences and call recording in one place.

Pick ZoomInfo if

• You run outbound at scale across SDR, marketing and RevOps teams.
• Intent signals and account-based marketing data drive who you target.
• You need data delivered by API, MCP or straight into a warehouse such as Snowflake or BigQuery.
• You already have a sales engagement tool and want the data layer, not another sequencer.

How they differ

Pricing. As of November 2026, Apollo.io has a free plan, with email campaigns limited to Gmail accounts. Its paid plans are priced per seat: Basic is listed at $49 per month and Professional at $99 per month on monthly billing, and annual billing costs less per month. Credits are pooled across the team and don't roll over, and every seat on an account must be on the same plan. ZoomInfo doesn't publish prices. Its pricing page describes custom packages by use case, a free trial, usage-based pricing for API access, and per-dataset contracts for warehouse delivery.

Core strength. Apollo.io's strength is that data and action live together. You find a contact and drop them into a sequence without leaving the tool. ZoomInfo's strength is the depth of its data platform: contact and company data, intent signals, and workflows for prospecting, ABM and customer expansion.

Where it falls short. Apollo.io's credit limits shape how much you can export and reveal, and the plan you need depends on usage you may not know in advance. ZoomInfo's quote-only pricing makes it hard to compare up front, and for a team of a few reps it's usually more platform than they'll use.

Buying process. Apollo.io is self-serve, with a Custom plan for larger teams. ZoomInfo goes through sales, so expect demos and negotiation.
