What is Apollo.io? A complete guide to features, pricing, and use cases

Apollo.io is a sales intelligence and engagement platform used by SDR teams, sales managers, and growth marketers to find prospects, verify contact data, and run outreach, all in one place. Between its database of 210 million contacts, built-in sequencing, enrichment queries, and CRM integrations, it can be hard to know exactly what Apollo covers and where it fits in your stack. This guide covers what Apollo.io is, what it does, what it costs, and how it compares to ZoomInfo.

If you're already using Apollo and want to connect it to the rest of your tools, we'll also show you how IFTTT automates the hand-offs between Apollo and your CRM, email marketing platform, calendar, and spreadsheets.

IFTTT is an automation platform that connects over 1000 apps and services. Instead of manually copying new Apollo contacts into your CRM or exporting leads to a spreadsheet, you build the connection once and it runs on its own.

What is Apollo.io?

Apollo.io is a sales intelligence and engagement platform that combines a large B2B contact database with outreach tools. Sales and marketing teams use it to search for prospects by job title, industry, company size, and dozens of other filters; verify contact information; and reach out through email sequences, a built-in dialer, and LinkedIn tasks, without switching between separate tools.

Unlike standalone data providers that sell contact lists and leave the outreach to you, Apollo does both. A sales rep can search for a target account, find the right contact, verify their email, and enroll them in an outreach sequence in the same platform. Apollo also includes a Chrome extension that surfaces contact data directly on LinkedIn or a company website, letting you pull a prospect into your pipeline with a single click.

Apollo was founded in 2015 and has grown into one of the most widely used platforms in B2B sales, with particular adoption among SDR teams, sales-led startups, and revenue operations teams managing high-volume outbound pipelines.

What is Apollo.io used for?

Sales development teams use Apollo as their primary prospecting tool, searching the contact database, building targeted lists by ICP criteria, and launching sequences to hit outreach volume without building lists manually in spreadsheets.

Account executives use Apollo's deal management and enrichment features to research accounts before calls, track deal stages, and keep CRM records accurate with enriched company and contact data.

Revenue operations teams use Apollo's CRM sync and reporting features to maintain data hygiene across their stack, ensuring that contacts in Salesforce or HubSpot stay updated as Apollo surfaces better information.

Marketing teams use Apollo's enrichment queries and intent data to score and segment inbound leads, route high-fit contacts to the right sequences, and sync contacts to email marketing platforms for nurture campaigns.

Founders and solo sellers use Apollo's free plan and lower-tier paid plans to run outbound prospecting without the cost of an enterprise data provider. Apollo's transparent pricing and self-serve onboarding make it one of the most accessible sales intelligence platforms for small teams.

How does Apollo.io work?

Apollo is built around its contact and company database, with a search layer on top that lets you slice the data by any combination of criteria and a sequencing layer that lets you act on the results.

Prospect search is the starting point. You filter by job title, seniority, geography, industry, company size, technology used, funding stage, headcount growth, and more. Results come back as a list of contacts with verified emails, phone numbers, LinkedIn profiles, and company details. You can save these searches, build lists, and push contacts into sequences directly from the results page.

Email sequences let you build multi-step outreach campaigns with automatic follow-ups, timing controls, and personalization through merge fields. You can set conditions that branch a sequence based on whether a contact opened an email or clicked a link, and track performance with open, reply, and click rates across every step.

The dialer is built into Apollo's interface on Professional and Organization plans. You can call contacts from within the platform, take call notes, log outcomes, and auto-dial down a call list, without a separate sales engagement tool.

Data enrichment works in two directions. Apollo can fill in missing fields on contacts you import from a CSV or your CRM, and it can push enriched data back into Salesforce or HubSpot via bidirectional sync. Apollo's Pro+ queries on IFTTT extend this further, letting you enrich any person or company mid-automation, using Apollo's database as a lookup layer for contacts arriving from other tools.

Deals and pipeline give Apollo some CRM-like functionality. You can create deals, assign stages, link contacts to accounts, and track activity. For teams using Salesforce or HubSpot as their system of record, Apollo syncs deal and contact updates bidirectionally so both platforms stay current.

Apollo.io pricing

Apollo offers a free plan with limited monthly credits, enough to evaluate the product before committing. Paid plans unlock higher credit limits, faster sequence speeds, and advanced features like intent data and the built-in dialer.

Pricing is approximate, check apollo.io/pricing for current rates.

Apollo's free plan is notably more generous than most competitors, which makes it a real starting point for individual reps and small teams rather than just a trial gate. Most growing sales teams move to Basic or Professional once they need higher export volumes or access to the dialer and intent data.

Apollo.io vs. ZoomInfo

ZoomInfo is Apollo's most commonly compared competitor, both offer large B2B databases and are used by enterprise sales teams. The main difference is breadth vs. accessibility.

ZoomInfo generally has a larger and more verified database and stronger intent data coverage, but it's priced for enterprise buyers and requires a sales call to get started. Apollo is more accessible for growing teams, includes sequencing and a dialer without add-on costs, and offers a real free tier. For teams that need to connect Apollo to other tools in their stack through automation, only Apollo has IFTTT support.

What are Apollo.io's limitations?

Data accuracy is the most commonly cited limitation. Apollo maintains over 210 million contacts, but contact data decays, people change jobs, emails go stale, and phone numbers change. Apollo flags bounced emails and uses community verification to improve accuracy over time, but no database eliminates this problem entirely. Teams running high-volume outbound should expect some bounce rate and verify critical contacts before campaigns.

Apollo is not a CRM replacement. Its deal management and pipeline features cover the basics, but teams with complex sales cycles, custom objects, or detailed reporting requirements will still need Salesforce or HubSpot as their system of record. Apollo works best as a prospecting and outreach layer that feeds into a dedicated CRM rather than as a standalone sales operations platform.

Intent data and the most advanced enrichment features are gated behind higher-tier plans. Teams that want to use buying signals as a core part of their outbound strategy need to be on Professional or Organization, which increases the per-seat cost significantly compared to Basic.

Data coverage outside of North America and Western Europe is thinner. Apollo's database is strongest for US-based contacts and companies. Teams targeting markets in Southeast Asia, Latin America, or parts of Eastern Europe may find gaps in coverage that require supplementing with other data sources.

The free plan's credit limits are tight enough that they're suited to evaluation rather than ongoing use. Teams that want to run meaningful outbound volume will need a paid plan fairly quickly after signing up.

How IFTTT works with Apollo.io

Apollo tracks what happens in your sales pipeline: new contacts created, accounts added, deals opened. IFTTT connects that activity to the other tools in your stack, routing new contacts into your CRM, syncing leads to your email marketing platform, and pulling in contacts from wherever they first appear, without anyone moving data manually.

IFTTT's Apollo integration includes 10 triggers, queries, and actions, including triggers like new contact created and new deal created, and Pro+ queries like enrich a person by email and enrich an organization that let you use Apollo's database as a data layer mid-automation.

Add contacts to Apollo from other tools

The most common use case: bringing contacts into Apollo from wherever they first appear. When someone books a Calendly meeting or gets added to a Google Sheet, IFTTT can create the Apollo contact automatically, so your database stays current without manual imports.

Sync Apollo deals with your CRM

When a new deal is created in Apollo, IFTTT can create the matching deal in Pipedrive, and the reverse works too. Stage changes in Pipedrive update the corresponding Apollo contact stage, keeping both platforms aligned without manual reconciliation.

Connect Apollo to email marketing

When Apollo creates a new account, IFTTT can add it to a Mailchimp audience automatically. The reverse works as well, new Mailchimp subscribers can be created as Apollo contacts, keeping your outreach and nurture lists in sync without a manual export step.

Frequently asked questions about Apollo.io

Is Apollo.io a CRM?

Apollo includes light CRM features, contact records, account management, deal pipelines, and activity tracking, but it's not designed to replace a full CRM like Salesforce or HubSpot. Most teams use Apollo alongside their CRM, with the two syncing bidirectionally. Apollo handles prospecting and outreach; the CRM handles post-sale activity and reporting.

How accurate is Apollo.io data?

Apollo uses a combination of machine learning, third-party data partners, and community verification to maintain contact accuracy. Email addresses are verified before export, and the platform flags bounced or outdated records over time. Data accuracy varies by industry and role seniority, it's generally strong for North American contacts in technology, finance, and professional services, and thinner for some international markets and niche industries.

What's the difference between Apollo.io and Outreach or Salesloft?

Outreach and Salesloft are pure sales engagement platforms, they handle sequences and pipeline management but don't include a prospect database. Apollo does both: it provides the contact data and the outreach tools in one platform. Teams that already have a data source and just need sequencing often choose Outreach or Salesloft; teams that need both tend to find Apollo more cost-effective.

Does Apollo.io work with Salesforce?

Yes. Apollo integrates natively with Salesforce on Professional and Organization plans, with bidirectional sync for contacts, accounts, activities, and deals. HubSpot, Pipedrive, and other CRMs are also supported depending on your plan.

Can small teams use Apollo.io?

Apollo's free plan and relatively low Basic pricing make it accessible for individual reps and small sales teams. Many early-stage startups use Apollo as their primary prospecting and outreach tool before they need a dedicated CRM or a more specialized engagement platform. The free plan's credit limits are tight but sufficient for evaluation and light use.
