What is Apollo.io?

Apollo.io combines a B2B contact database with outreach tooling, so prospecting and sequencing happen in one place. You filter companies and people by industry, size, technology and job title, save the list, then enrol contacts in multi-step email and call sequences with reminders. Its AI layer drafts and personalises email copy and consumes credits, so the generative parts are metered separately from plain searching. The differentiator is the combination: contact data, buying signals and an outreach engine in one subscription instead of three tools.

FAQ

Where does the contact data come from?

It is assembled from public web sources, contributed data and partner feeds, then verified and enriched over time. Coverage is strongest for English-speaking business contacts and thinner elsewhere, so verify important records before a large send.

Are the AI credits free?

No. Generative features such as AI-written email drafts and certain enrichment actions consume credits separate from your seat. Paid plans include a monthly allowance, and heavy outreach usually needs extra credits on top.

Can I use Apollo for cold email at volume?

The sequences can send at volume, but deliverability depends on your own domain setup, warm-up and content. Apollo does not make an unverified list safe, and local anti-spam rules still apply to every campaign.
