Send timed follow-up emails to free trial users automatically

Checks each trial user's progress daily and emails the right nudge to help turn them into paying customers.

How the work actually flows

It repeats. Daily check runs again; runs once per each active trial user.

The problem it solves

Free trial users need the right nudge at the right moment, but keeping track of who's on day three versus day thirteen across every signup is impossible to do by hand. Miss the window and you likely lose the customer for good.

Who it fits

SaaS companies running free trials who want consistent, timely follow-up without manual tracking.

How it works

  1. Every day, the system checks all users currently on a trial
  2. It calculates how far along each user is in their trial
  3. It sends the matching email for that stage, from an early nudge to a last-day reminder
  4. This repeats daily until each user converts or the trial ends
What you get

Trial users nudged at exactly the right moment

You get the right follow-up email sent automatically to every trial user based on exactly where they are in their trial.

What you get

Timely, stage-based follow-up emails sent to every active trial user.

What you need

A MongoDB database and a Gmail account.

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.
