Apollo.io Guide: AI Sales Prospecting for Small Teams

Apollo.io is a sales prospecting platform. It combines a large B2B contact database (240 million+ contacts at 30 million+ companies, by Apollo’s count) with tools to email, call and track prospects in one place. In 2026 it added an AI Assistant that can research accounts, build lead lists and draft outreach from a plain-language request. For a small sales team or a founder doing outbound, it can replace several separate tools. This guide helps you define who to target, build a first outreach sequence, stay out of spam folders and choose a plan.

Find

Search contacts and companies by title, industry, size, location, technology used and buying signals such as job changes or hiring.

Enrich

Fill in missing emails, phone numbers and company details in your CRM, and keep records fresh over time.

Engage

Multi-step sequences of emails, calls and LinkedIn tasks, plus a dialer, meeting scheduler and call recording.

AI Assistant

Describe a goal (“find IT directors at 50–200 person firms in Ohio”) and it builds lists, researches accounts and drafts sequences for you to review.

Reply and meeting rates vary widely by industry and list quality. Use your own numbers after a few weeks. Sending fewer, better-targeted emails beats raising volume.

Step 4: Stay out of the spam folder, and on the right side of the law

Deliverability & compliance checklist

Outreach goes from a separate domain (like getyourcompany.com), not our main email domain. SPF, DKIM and DMARC are set up on the sending domain. New inboxes are warmed up for 2–4 weeks before full volume, using Apollo’s domain warming. We only email verified addresses, and we pause on high bounce rates. Daily volume per inbox stays modest and ramps up gradually. Every email includes our business address and an easy way to opt out (CAN-SPAM). We check Do Not Call lists before cold calling, and we’re careful emailing EU and UK contacts (GDPR).

Which Apollo plan fits?

Plan finder

We use Microsoft 365 or Outlook for email, not Gmail. We'll run regular email sequences, not just look up contacts. We want the dialer, call recording or AI features. We need deep CRM integration (Salesforce or HubSpot). We need single sign-on, API access or custom data volumes.

Tick what applies.

Apollo's plans are Free, Basic, Professional and Custom, with credits pooled across your team that reset each billing cycle. Annual billing is cheaper than monthly. Check current prices and credit limits on Apollo.io.

Treat the data as a starting point.Contact data goes stale as people change jobs. Verify before you send, and don't trust any vendor's accuracy or "meetings booked" claims until you've tested them on your own market. Use AI to research and draft, but have a person review every first email before it goes out.

Frequently asked questions

Is Apollo free?

Yes. There's a free plan with no time limit that includes database search and email campaigns from Gmail accounts. Paid plans add more credits, other email providers, AI features, calling and deeper integrations.

Is cold emailing legal?

In the U.S., B2B cold email is legal under CAN-SPAM if you use accurate headers and subject lines, include your physical address, and honor opt-outs promptly. Rules are stricter in the EU, UK and Canada, so get advice before targeting those markets.

What does the AI Assistant actually do?

You describe a goal in plain language, and it uses Apollo's data to find contacts, research accounts, build or improve sequences and pull reports. You review and approve its work. It speeds up the busywork, but your judgment on who to contact and what to say still matters most.

Does it work with our CRM?

Apollo integrates with major CRMs, including Salesforce and HubSpot, plus 200+ other tools. Deeper CRM sync features are on the higher plans.
