This n8n workflow performs automated menstrual cycle tracking, reminders, and personalized wellness guidance by managing subscriber data and delivering timely emails based on each userâs cycle phase. It starts when a user submits their menstrual cycle details through a form, capturing inputs such as last period date and cycle length. The workflow calculates key cycle milestones including next period, ovulation, fertile window, and PMS phase, and stores this data in Google Sheets as a centralized database. A personalized welcome email is immediately generated and sent to the user with their cycle overview. The system then runs daily at 8 AM to evaluate each subscriberâs current cycle phase and determine whether a reminder should be sent, such as period alerts, ovulation insights, or PMS preparation tips. It ensures duplicate messages are avoided by tracking previously sent emails. Additionally, the workflow runs a weekly AI-powered wellness digest that generates personalized insights, tips, and guidance based on the userâs current cycle phase. Finally, all emails are logged and tracked to maintain consistency and provide a complete history of user engagement, enabling a fully automated and personalized menstrual wellness experience.
