A cadence is a set of actions or tasks that are performed at specific intervals or stages. In the LeadsApp CRM, a cadence is used to help sales teams be more efficient by providing a series of touch points, such as emails, texts, calls, and voicemails, to be performed in a specific order. Cadences are tied to a data form and run in the background, with different logic or triggers determining when to move from one step in the series to the next. The goal of using a cadence is to improve the efficiency and effectiveness of the sales team by providing a structured approach to managing leads.
