Lifecycle tool vs. general ESP?

Once you have 3+ triggered sequences, general ESPs become painful. Customer.io, Loops, and Braze are built for event-triggered lifecycle. Mailchimp is not.

Who owns lifecycle marketing?

The founder until $2M ARR. Then a product marketer or growth engineer — never handed to a generalist marketer, because the work is engineering-adjacent.

Push notifications too?

Only for mobile-first products where the notification carries information. Otherwise, email delivers more signal with less friction.

Lifecycle Marketing: The Missing System Between Signup

Lifecycle marketing is the sequenced set of touches that turn signups into activated users and activated users into paying customers.

Lifecycle Marketing for Startups

Most startups have acquisition and retention, and nothing in between. That gap is where 60% of signups die. Lifecycle marketing is the specific work of filling it.

The five stages

1) Onboarding (first 7 days). 2) Activation (first key action). 3) Habit (repeated use within 30 days). 4) Expansion (upgrading, adding seats). 5) Advocacy (referrals, reviews, community). Each stage has one metric and one intervention.

Trigger-based, not calendar-based

Every lifecycle email fires from a user event, not a date. "Sent 3 messages" or "Invited a teammate" is a trigger. "Day 7" without context is spam. The difference is respect — you send when the user's state warrants it.

The three sequences that matter most

Onboarding to activation (7 emails max, event-triggered). Trial to paid (3 emails max, timed to trial expiry). Churn recovery (2 emails, sent after cancel with a specific asked-for reason). Everything else is optional.

What to measure

Time-to-activation (leading indicator of retention). Trial-to-paid conversion. Churn recovery rate. Reply rate on lifecycle sends (yes, reply — one-way lifecycle emails miss half the signal).
