# Apollo Core Workflow B: Email Sequences & Outreach ## Overview Build Apollo.io email sequencing and outreach automation via the REST API. Sequences in Apollo are called "emailer_campaigns" in the API. This covers listing, searching, adding contacts, tracking engagement, and managing sequence lifecycle.
