What it does

Five things that move trials toward payment.

01

Starts with activation - the first message points to the one action that predicts conversion.

02

Branches by usage - active users and stuck users get different help.

03

Uses value moments - upgrade CTAs trigger after setup, usage, or team invite signals.

04

Offers human help - low-usage trials can ask a person before they silently expire.

05

Stops after payment - Stripe success exits the sequence and updates lifecycle stage.

Deep dive

Why trial nudges on WhatsApp work.

Most trials fail quietly. WhatsApp creates a direct path from signup to activation, help, and upgrade.

01 Why trials stall

Users sign up with intent but lose momentum before they reach the product moment that proves value. Behavior-based nudges recover that momentum.

  • Silent after "yes" — wire your Flow to the CRM milestone (donation cleared, booking confirmed, ticket closed) and let the thread go quiet the instant the job is done. No duplicate ask, no nudge — one trustworthy conversation people actually open next time.

02 How to enhance it

Add product event triggers, PQL scoring, team-invite branches, account owner routing, and Stripe payment-success suppression.

03 Gotchas

Do not message every login, suppress paid accounts instantly, avoid hard-sell copy before activation, and respect quiet hours by user locale.

The point: trials convert when users reach value before the clock runs out.

Proof

What it looks like in the wild

Once the messages matched product usage, the upgrade CTA stopped feeling early.
