A Sequence (also called a Cadence) is a structured, multi-touch outreach program with a defined number of steps, channels (email, phone, LinkedIn), and timing intervals designed to maximize the probability of connecting with a prospect over a set period. Sequences automate the scheduling and reminders but should not automate the personalization — the best sequences combine process efficiency with message relevance. Most modern outbound sequences run 8–15 touches over 3–6 weeks before marking a prospect as unresponsive.
