Apollo.io is an all-in-one go-to-market platform that collapses a whole sales stack into one tool. Instead of buying contact data from one vendor and sequencing from another, Apollo pairs a 210M+ contact database across 35M+ companies with email sequences, a dialer, enrichment and intent data in a single interface. It even has a free plan, and paid tiers land at a fraction of ZoomInfo. The honest catch: data accuracy dips outside the US — bounce rates of 15–25% on big lists are a recurring complaint — and the credit system quietly pushes upgrades as you scale.

Frequently asked questions

How much does Apollo.io cost in 2026? +

A free plan, then three paid tiers per user per month: Basic $49, Professional $79, Organization $119, all billed annually. Paying monthly costs more — $59 / $99 / $149 — and Organization needs a minimum of three users. For perspective, a five-person team on Professional pays about $395/month annually — a fraction of a comparable ZoomInfo contract.

How is it different from ZoomInfo + Outreach? +

It's one tool instead of two. Teams normally buy contact data from one vendor and email sequencing from another, then wire them together. Apollo puts a 210M+ contact database, multi-step sequences, a dialer, enrichment and Bombora intent data in a single interface, so a rep can find a prospect and start outreach without leaving the app. Fewer tools, one bill, far less than the premium incumbents charge separately.

How accurate is Apollo's data? +

Good in the US, weaker elsewhere — the most consistent complaint. US contact accuracy sits around 88%, but it drops outside North America and for smaller companies, with 15–25% bounce rates reported on large exported lists. Direct-dial phone accuracy runs about 60%. The takeaway from reviewers: verify emails before big sends and treat Apollo as a data source, not a guaranteed-clean list.

How does the credit system work? +

Apollo meters email and phone reveals, exports and enrichment through credits that vary by plan. Fine at moderate volume, but heavy prospecting burns allowances quickly, and running low nudges you toward a higher tier or add-on credits. Budget on how many contacts you'll reveal and export each month, not just seats — credit consumption, not the per-user price, drives real cost at scale.

Apollo or ZoomInfo? +

On price and breadth Apollo wins for most SMB and mid-market teams — it bundles data and engagement in one tool at a fraction of ZoomInfo's cost, and even offers a free plan. ZoomInfo carries deeper, more rigorously verified data, stronger international coverage and more enterprise controls, which matters if accuracy is mission-critical or you sell heavily outside the US. US-focused team wanting prospecting and outreach in one affordable place? Apollo's the value pick. Need the most accurate database money can buy? ZoomInfo still leads.

Should I send campaigns from Apollo itself? +

Cautiously. Apollo's sequencer is capable — multi-step campaigns, A/B testing, manual LinkedIn and call tasks, conditional logic — but reviewers note deliverability trails dedicated sending tools. A common pattern: build and manage prospecting in Apollo, send high-volume campaigns through a specialist deliverability platform. For lighter outreach, sending from Apollo directly is fine; at scale, warm your domains and watch inbox placement closely.
