Frequently Asked Questions
Do most outbound teams use Clay and Apollo together?
Yes — the common stack is Clay for enrichment and personalization + Apollo or Instantly for sequencing. Clay finds and enriches prospects; Apollo sends the sequences. Each does its part of the outbound workflow.
Is Clay worth the cost?
For teams doing serious outbound, yes. Clay's enrichment reduces manual research time dramatically and produces the personalization data that improves reply rates. Most teams report 2–4× improvement in response rates from properly enriched sequences.
Does Apollo have enrichment features?
Apollo has built-in enrichment from its own database. It is solid for basic contact data but does not match Clay's waterfall enrichment from 75+ sources or the AI-powered custom research that Clay enables.
