Seeking Guidance on Email Enrichment in Clay: Documentation Needed

Email Enrichment: Hi All, new Clay user and looking for documentation or a guide to enrich email. I'm not finding what I need as a search in the docs returns a single result anchoring to the novalidate tag. (wrong Clay support/docs site) Goal is to enrich(?) search results in a table. I added an email column, but then I believe I need to burn some more credits to fill that column somehow? Thanks in advance for any pointers. P.S. Is email not part of the standard search results for companies or people?
