What is Apollo?

Apollo is a sales intelligence and engagement platform that combines a large B2B contact database with outreach automation and lightweight CRM functionality. The core idea is that sales teams shouldn't need four different tools to go from "identify a target company" to "booked meeting" — Apollo tries to handle the whole workflow in one place.

The database is Apollo's standout feature: over 275 million contacts with attributes including job title, seniority, company size, industry, geographic location, revenue, funding stage, and technology stack. You can filter this database with precision — for example, "find all VPs of Product at US-based SaaS companies with 100–500 employees that use Salesforce and have raised Series B or later" — and export a list of verified email addresses and LinkedIn profiles in minutes.

Once you have a list, Apollo lets you enrol prospects in automated multi-step email sequences, track opens and replies, and manage the pipeline in a basic CRM. The AI features write initial sequence drafts and suggest personalisation based on the prospect's profile. For early-stage B2B companies that need a quick path from "no pipeline" to "booked meetings", Apollo is one of the most efficient starting points available.

Who is it for?

  • Early-stage B2B founders doing their own sales and needing to build a prospect list fast
  • SDRs and account executives who need to prospect efficiently without a dedicated data provider
  • Growth teams testing new ICP segments before committing to expensive outbound infrastructure
  • Recruiters searching for passive candidates by role, location, and company size
  • Small sales teams that need a combined database + outreach tool without paying for separate subscriptions

Key features

  • Contact database: 275M+ contacts with emails, phone numbers, and LinkedIn profiles
  • Advanced filters: 65+ filtering attributes including job title, company, industry, tech stack, funding, headcount, and keywords
  • Sequences: multi-step automated email sequences with scheduling, personalisation fields, and A/B testing
  • AI email generation: describe your product and ICP and Apollo drafts outreach sequences for you
  • CRM integration: basic pipeline management built in, plus integrations with Salesforce, HubSpot, and Pipedrive
  • Chrome extension: surface contact info and company data directly on LinkedIn profiles
  • Intent signals: see which companies are actively researching topics relevant to your product (paid feature)
  • Analytics: open rate, click rate, reply rate, and bounce rate per sequence and per step

Step-by-step setup

  1. Go to apollo.io and create a free account — no credit card needed
  2. Complete the onboarding: add your company name, role, and what you sell
  3. Go to Search and use the filters on the left to define your ICP:
    • Job Titles: "VP of Sales", "Head of Marketing", "Founder"
    • Company Size: e.g., 50–500 employees
    • Industry: SaaS, FinTech, Healthcare, etc.
    • Location: United States, Europe, etc.
    • Technologies Used: Salesforce, HubSpot, Shopify, etc.
  4. Review the results and save contacts — you'll see email addresses for contacts within your monthly credit limit
  5. Create a list and add your saved contacts to it
  6. Go to Sequences and create a new sequence — use the AI generator to draft initial emails based on your product description, or write your own
  7. Enrol your contact list in the sequence, set sending delays (3–5 days between steps), and activate
  8. Install the Chrome extension to find contact info when browsing LinkedIn — saves time on individual prospect research
  9. Connect Apollo to your CRM (Salesforce, HubSpot) under Settings > Integrations if you're managing pipeline elsewhere

Tips for getting the most out of it

  • Validate your filters on a small sample first. Build a list of 20 contacts, manually review their LinkedIn profiles, and ask yourself: are these genuinely my ICP? If more than 20% are off-target, refine your filters before scaling up.
  • Use the tech stack filter strategically. If your product integrates with or replaces a specific tool, filtering for companies using that tool gives you a warm angle. You can open with "I see you're using [tool] — we integrate with it and help teams like yours do X."
  • Clean your list before importing to sequences. Apollo's email verification isn't perfect. Run your export through a verification tool (NeverBounce, ZeroBounce) before sending sequences to keep bounce rates below 3%.
  • Combine Apollo for prospecting with Instantly for outreach. Apollo excels at finding contacts; Instantly's unlimited inbox + warm-up infrastructure excels at sending. Many growth teams use both in combination.
  • Check intent signals before cold outreach. Apollo's intent data shows which companies are actively searching for solutions like yours. If a prospect is showing strong intent, prioritise them and personalise your outreach — they're 3–5x more likely to respond.
