Process

How it works

A simple 3-step system everyone can follow.

Step 01

Subscriber Intake & Cycle Calculator

Subscribers submit name, email, last period date, and cycle length; the AI agent calculates dates (next period, ovulation, fertile window, PMS) and stores them.

Step 02

Daily Cycle Monitor & Smart Reminders

Every morning at 8AM, the AI agent reviews active subscribers, determines today’s phase, constructs phase-specific emails, and sends them via Gmail after validating no duplicates.

Step 03

Weekly Wellness Digest

Each Sunday at 9AM, the AI agent sends phase data to GPT-4o, which generates tailored tips across five wellness categories; the digest is emailed in branded HTML.


Example

Example workflow

A realistic scenario showing day-by-day actions.

A subscriber named Anna signs up on a Monday, providing name, email, last period date, and cycle length of 28 days. The AI Agent immediately sends a personalized welcome email with her full cycle overview. In Anna’s 28-day cycle, the Agent triggers four emails: 3 days before her next period (preparation tips), on the period start day (comfort tips), on ovulation day (fertility energy tips), and at the start of PMS (mood and boundary tips). Every send is logged, and the cycle dates recalculate if her period shifts. On the following Sunday, a GPT-4o generated wellness digest is sent based on her current phase.

FAQ

FAQ

Common concerns and practical guidance.

The AI Agent checks the last email type sent for the current cycle before sending, ensuring a single reminder message per phase per subscriber. If a period date shifts, the Agent recalculates future dates and adjusts upcoming sends accordingly. A centralized Send Log provides visibility into each delivery and helps prevent any re-sends. If two phase emails would occur on the same day, the Agent prioritizes the most relevant phase based on the subscriber's current cycle day. This approach minimizes confusion and keeps communications clean.

The AI Agent stores name, email, last period date, cycle length, calculated cycle dates, last email sent, and a delivery log. This data drives date calculations, phase detection, and email sequencing. Data is used to personalize messages and ensure timing aligns with each subscriber’s unique cycle. The Send Log enables auditing and engagement analysis. All processing respects the defined workflow and keeps subscriber data organized for ongoing campaigns.

The AI Agent is designed to track each subscriber’s current cycle based on their last period date and cycle length, recalculating as new data comes in. It maintains a single active cycle per subscriber within the Google Sheet, updating dates as needed. If a subscriber reports a significantly different cycle length, the next recalculation reflects that change. The system is built to prevent overlapping cycle tracking that could cause conflicting emails. For most use cases, a single cycle per subscriber provides clear, actionable reminders.

Setup is a one-time configuration that includes creating a Google Sheet with the required sheets, connecting Gmail and Google Sheets OAuth2, and placing your OpenAI API key. You will also import or configure the intake form and email templates. After connectors are authenticated, you can customize the cycle parameters and recipient list. The initial data migration from existing subscribers is optional but helpful for immediate testing. Once configured, the AI Agent runs automatically with no ongoing manual steps.

Required integrations include Google Sheets for data storage and logging, Gmail for sending emails, and OpenAI GPT-4o for wellness content. An intake form (e.g., via n8n Form) is used to capture new subscribers. Additional optional components include a dedicated Send Log sheet for auditability and branding templates for HTML emails. These integrations work together to enable end-to-end automation of data capture, date calculations, messaging, and wellness coaching.

Yes. The AI Agent supports opt-out handling by respecting subscriber preferences. When a user unsubscribes, the agent pauses sends for that email type and marks the subscriber as inactive in the sheet. It stops future phase emails and digest emails unless the subscriber re-enrolls. Opt-out data is also logged to maintain accurate engagement metrics. This ensures compliance with user consent while preserving system integrity.

Weekly wellness tips are generated by GPT-4o using the subscriber’s name, current phase, cycle day, and days until next period. The AI blends phase-specific guidance across five categories: energy, nutrition, movement, mindset, and expectations for the week. Each tip is formatted into a branded HTML email with adaptive colors and emojis based on the phase. The digest is sent automatically, and every send is recorded in the delivery log for transparency and analysis.
