Get as much data as you need at no extra cost - all included in your inbox plan. People search, enrichment, SMTP + deep catch-all verification.
The three jobs
Cold-email "data" is really three discrete jobs stacked together. Search for people. Enrich them to find their email. Verify the email lands. Most operators pay a different vendor for each - three logins, three layers of complexity, three markups stacked.
Bundled tools that do all three usually cost a fortune. We don't charge extra for any of it - you pay for access to inboxes, the rest comes free.
01 - People search
800M professionals, filtered by title, industry, location, headcount. Apollo's job.

02 - Enrichment
50+ databases pulled, candidate emails tested, heuristics applied. Leading enrichment providers' job.

03 - Verification
SMTP check + deep catch-all check. Two vendors' job everywhere else.

01 - People search
800M+ professionals indexed across every industry, role, and geography. Filter by title, company, industry, headcount, location, funding stage - the same dimensions you'd search on in Apollo. The result set runs 80–90% of Apollo's for the same query, depending on niche.
And every contact gets re-validated on a 30–60 day cycle. Job changes captured. Old emails rolled out. New ones rolled in. The contact you pulled today is the contact who actually has that role today.

included · no credits02 - Enrichment
Once you have a name and a domain, the question is: what's the email? We pull from 50+ different databases, generate candidate emails using heuristics, and test each one. The one that resolves cleanly is the one we hand back.
We've benchmarked our enrichment head-to-head against the top enrichment services in the market. Neck-and-neck on accuracy. In some cases, actually better.
01 · Pull
Every credible source we have access to is hit in parallel. Public records, pattern banks, breach-validated identities, our own crawl.
02 · Generate
Heuristics on name + domain shape: first.last@, f.last@, firstlast@, etc. Plus pattern inference from existing employees at the same company.
03 · Test
Each candidate runs through our verification stack before we hand it back. The one we return is the one that lands.
Head-to-head benchmark
We benchmark our enrichment against the top providers across hundreds of thousands of sample contacts. Neck-and-neck on match rate. In some cases, ours pulls ahead. You don't pay for any of it. It's bundled into your inbox plan.
03 - Verification
Verification is two checks. SMTP verification - does the mailbox accept mail? - is solved tech across the industry. We do it well. So does everyone credible.
The hard one is deep catch-all verification: when a domain accepts every address ("info@", "contact@", and yours), is the email actually deliverable to a real person? Most verifiers fall down here. Ours is built on methods that work really well, so we hit very high accuracy.
We've benchmarked head-to-head against the top verification services. Neck-and-neck. In some cases, ours is actually better.
SMTP verification
A handshake with the receiving server. Solved tech across the industry - every credible verifier hits this, including ours.
Deep catch-all verification
When the server says yes to every address, you need a deeper check. Methods that work - very high accuracy.
Head-to-head benchmark
We benchmark our verification stack against the top services in the market - both SMTP and deep catch-all. Neck-and-neck on accuracy. In some cases, ours actually pulls ahead. You pay for inbox access. The rest comes free.
Break it down
Plug in your monthly volume and what you're paying across source, enrichment, and verification. We'll show your cost per 1k valid emails and the annual savings if you switched.

Old data dumps
Some cold emailers prefer cheap, old data dumps for their lists. Some lead sellers package that stale data and sell it back to you. It's shitty data - about 30% of professionals change roles every year, so half the contacts don't exist in those roles anymore.
No point using it. Ours is fresh, enriched on demand, and verified on demand.
The alternative
Ours is fresh, enriched on demand, and verified on demand. Every contact re-validated on a 30–60 day cycle. The contact you pull today is the contact who actually has that role today.
800M professionals refreshed monthly. Enrichment on par with the leading providers. Deep catch-all on par with the gold standard. Included.
