How to Find Work Emails: Enrich Data for People with Datagma | Slack

Hi...I'm trying to find work emails for my targets and am struggling with the best way to go about this. I chose "Enrich Data" and chose "Emails" under the "People" banner. I'm not sure which action is best, but chose the Datagma option. When I ran it for the first ten contacts, nothing happened. Not sure what I'm doing wrong.
