Outreach Automation platforms orchestrate multi-channel sales prospecting sequences — coordinating email, phone, LinkedIn, and SMS touches in timed cadences with automated follow-ups and task triggers. Core capabilities include sequence/cadence builder with multi-step workflows, automated email sending and follow-up, call and LinkedIn task scheduling, A/B testing of sequence variants, engagement tracking (opens, clicks, replies), rep productivity dashboards, and integration with CRM, dialer, and email systems. The category spans dedicated outreach platforms (Outreach, Salesloft, Apollo sequences, Instantly) and outreach modules within broader sales engagement suites.
