Sales Engagement Platform (SEP)

2026-05-31 8 min read

A sales engagement platform (SEP) orchestrates the multi-touch outbound and inbound cadences used by sales development reps (SDRs) and account executives (AEs). Functions include sequenced email + call + LinkedIn outreach, A/B testing of cadences, prospect engagement tracking, and CRM activity sync. Leaders include Outreach, Salesloft, Apollo.io, and HubSpot Sales Hub. The category overlaps with revenue intelligence (Outreach acquired Sounds in 2020) and SDR AI agents (newer 2024–25 wave).
