Head-to-head
Apollo vs ZoomInfo: which one in 2026?
Apollo.io is a sales intelligence and outreach platform that pairs a contact database with email sequencing and a dialer, and ZoomInfo is a go-to-market data platform from ZoomInfo Technologies LLC sold as quote-only packages. Apollo starts free and tiers up by plan name, while ZoomInfo is bought through a pricing form.
Verdict
ZoomInfo sits above Apollo.io in the category ranking, and that order holds for organizations buying a broad, contracted data platform with warehouse delivery and a longer certification list. Apollo.io is the better start for a small team, since a free plan and four named tiers let someone test the work before a sales call. Neither pricing page gave a usable amount, so request quotes that spell out credits, seats and API access.
Apollo and ZoomInfo side by side
| Apollo | ZoomInfo | |
|---|---|---|
| Price entry | Quoted | Quoted |
| What can a team try before talking to sales? | A Free plan with no time limit exists, limited to email campaigns with Gmail accounts. Basic and Professional show no dollar amounts on the pricing page. | A free trial is linked from some use cases, with no length or terms stated. Pricing runs through a Get pricing form, and the FAQ headings on the page have no answers. |
| How is the product packaged? | Four tiers: Free, Basic, Professional and Custom. Professional adds higher credit limits, AI features, call recording and advanced CRM integrations; Custom adds SSO and API access. | Packages by use case, among them prospecting and pipeline, ABM, lead management, deal execution and data enrichment. The page gives one line per package and no contents. |
| How big is the data and where does it come from? | The product page states 240M+ contacts and 30M+ companies. Apollo Profile blends first-party CRM data, call recordings and signals such as job changes and website visits. | A waterfall enrichment flow checks sources, verifies across them, adds company context and keeps records fresh. The pages opened state no database size and name no signal types. |
| Outbound tooling | Email sequencing, a Parallel Dialer, domain warming, inbox rotation and reputation monitoring sit inside the product, plus compliance tools for GDPR, CAN-SPAM and DNC. | The products page lists forty plays that can run immediately and agents acting on the customer record. An example agent researches an account and drafts an opener. |
| Where can the data go? | Apollo Anywhere works from a CRM, ChatGPT, Claude, Gmail and the browser. The product page cites 200+ integrations without naming the CRMs. | Data can be delivered to Snowflake, Databricks, BigQuery or S3, contracted per dataset. API, MCP and CLI access is priced on usage, not seats. |
| Which certifications are named? | The Trust Center lists SOC 2 Type 2, ISO/IEC 27001, GDPR, CCPA/CPRA, EU-US DPF and CASA Tier 2. Hosting region is not stated; AWS and Google Cloud are subprocessors. | The security page names ISO 27001, 27701, 27017 and 42001:2023, plus SOC 2 Type II. Customer data is encrypted at rest with AES256, and hosting is described only as major cloud providers. |
| What is stated about AI training and retention? | The Trust Center says nothing on training with customer data. Data Erasure and Disk Encryption appear as headings only, with no retention periods or encryption details. | The security page does not address AI training on customer data or retention periods. Encryption is the one data-handling detail it states in full. |
Where each one wins
Apollo wins on
- A free plan without a time limit lets one rep start prospecting before anyone signs a contract
- Sequencing, dialer, deliverability tools and the database live in one product, so a small team needs fewer vendors
- Plan names run from Free to Custom, which makes the upgrade path easier to read than a list of use-case packages
ZoomInfo wins on
- Warehouse delivery to Snowflake, Databricks, BigQuery or S3 suits data teams that want records outside the app
- The security page lists four ISO certifications including ISO/IEC 42001:2023, plus a stated AES256 encryption standard
- Use-case packages for ABM, deal execution and customer expansion go beyond prospecting into the rest of the revenue process
