Email Automation and Lifecycle Sequences Questions

Develop understanding of email automation platforms and how to build automated email sequences that trigger based on user actions or timeline. Common sequences: onboarding (triggered by sign-up, delivered over days), re-engagement (triggered after period of inactivity), win-back (for lapsed customers), post-purchase (upsell, cross-sell), feature announcement (to relevant users). At junior level, be able to design an email sequence: map out email flow and triggers, define content for each email, discuss frequency and timing, explain how you'd measure sequence effectiveness. Show familiarity with email automation platforms (Marketo, HubSpot, etc.). Discuss segmentation within sequences—do different user types get different content?
