Deliverability

Frequently asked questions
Apollo is the GTM agentic system that unifies B2B data, AI-driven intelligence, and execution tools into one connected system — to help your team find the right buyers, reach them at the right moment, and close more deals without stitching together five different tools to do it.
240M+ contacts and 30M+ accounts, with verified emails, mobile numbers, direct dials, firmographics, job changes, intent signals, and more. It's one of the largest and most complete B2B datasets available — and it gets more accurate the more it's used.
Accurate enough to take Claiton.io's email deliverability from 72% to 94%. Apollo regularly refreshes contact data across its network, so records stay current instead of going stale. You're not working off a static export — you're working off a living dataset that improves over time.
No single data provider has everything. Waterfall enrichment fills gaps in your records by pulling from 20+ trusted third-party sources, in sequence, until each field is complete. Higher match rates, fewer dead records, better deliverability. One less thing to worry about.
Yes. Connect your CRM, data warehouse, call transcripts, calendar, emails, deals, and third-party data sources. Apollo works with what you already have, so your first-party reality becomes part of every workflow, not something siloed off in another tool.
That's exactly how most teams use it. Apollo pipes enriched, verified data directly into Salesforce, HubSpot, or wherever you work — filling gaps, deduplicating records, and keeping things fresh. No rip-and-replace required.
Apollo gives you world-class B2B data at an affordable rate, built into a platform that lets you act on it. That way you're not paying for a data export you then have to move somewhere else. The data lives where the work happens: prospecting, outreach, and engagement all in one place.
