Send personalized cycle-based wellness emails automatically

Tracks each subscriber's cycle and sends personalized phase reminders and AI wellness tips by email, on schedule.

How the work actually flows

It repeats. Daily phase check repeats; runs once per each subscriber currently changing phase.

The problem it solves

You want to support the women in your community through every phase of their cycle, but sending the right message at the right time for each person by hand is impossible at scale. Generic one-size-fits-all content feels impersonal and gets ignored.

Who it fits

A wellness coach, women's health platform, or community builder offering cycle-aware support to subscribers.

How it works

  1. A subscriber submits their cycle details through a simple form
  2. The automation calculates their period, ovulation, and fertile window dates
  3. A welcome email with their personal cycle overview is sent right away
  4. Each morning it checks who is entering a new phase and sends the matching reminder email
  5. Every week it uses AI to write a fresh wellness digest tailored to each subscriber's current phase
What you get

Subscribers who feel personally supported all cycle

Each subscriber gets timely, personal reminders and fresh wellness tips that match exactly where they are in their cycle.

What you get

Personalized phase reminder emails and a weekly AI-written wellness digest for every subscriber.

What you need

A Gmail account, a Google Sheets account, and an OpenAI API key.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
