<b>Clay vs Apollo: enrichment engine vs all-in-one</b>
Both feed your sequences, but they're built for different jobs.

Apollo is a database + sequencer: 270M+ contacts, find-and-send in one tab, $49-99/mo per seat. Data is decent, deliverability tooling is thin, and emails get shared widely (read: burned).

Clay isn't a database — it's a waterfall enrichment table that chains 50+ providers, so if one source misses an email, the next tries. Pricey (credits burn fast at scale) and it has a learning curve, but match rates crush single-source tools.

Pros / Cons
— Apollo: cheap, fast, all-in-one, over-shared data
— Clay: best-in-class match rate, no native sender, credits add up

Who it's for: Apollo for quick small-team prospecting. Clay when data quality is your bottleneck and you send through Smartlead/Instantly.

Verdict: 4/5 Apollo for speed, 4.5/5 Clay for accuracy. Use Clay to build the list, a real sender to mail it. Apollo tries to do both and stretches.
