Automated Email Trigger Design

As a marketing automation specialist for small businesses, help me design 3 automated email triggers that will nurture customer relationships without requiring daily manual work. For each trigger, specify: 1) The customer action or time point that initiates the email, 2) The content and offer that would be most relevant at that moment, 3) Exact implementation steps in simple email platforms, 4) How to make the automated email feel personal and local, and 5) How to measure its effectiveness. My business is [describe your business] and key customer touchpoints include [describe customer journey points].
