Lifecycle messaging triggered by behaviour, not by the calendar
Newsletters go out on Tuesdays; lifecycle messages go out when something happens. The event model — signups, orders, inactivity, milestones — that makes email and WhatsApp feel timely instead of scheduled.

The difference between marketing email that is read and marketing email that is deleted is usually timing. A message that arrives because of something the customer just did — signed up, bought, stalled, hit a milestone — is relevant by construction. A message that arrives because it is Tuesday is relevant by luck. Lifecycle messaging is the practice of building the first kind, and it starts with events.
Define the events
List the moments in the customer's life with your business: account created, first action taken, first purchase, repeat purchase, cart abandoned, subscription renewed, usage dropped, support ticket closed, review left, referral made. Each is an event with a timestamp and properties. If your systems do not emit these events, the first job is to make them — a webhook, a database trigger, a nightly diff.
Design a journey per event
For each event: what should happen, on which channel, how many touches, ending on what condition. Cart abandoned: a WhatsApp reminder in an hour, an email with the items the next morning, a last nudge with a small incentive two days later, stopping if they buy. Usage dropped: a check-in from a named person, a help resource, an offer of a call. Keep journeys short and specific; long branching journeys are rarely maintained.
Choose the channel by the moment
Transactional and time-sensitive: WhatsApp or SMS. Content and consideration: email. Anything requiring a reply: the channel the customer used last. Respect the customer's stated preference over all of this, and respect quiet hours in their time zone.
Measure by journey
For each journey: entries, completions, conversions, unsubscribes, revenue. A journey with high unsubscribes is annoying people; one with no conversions is not worth its inbox space. Retire what does not work, and write the next journey from the next most common event.
Questions people ask next
- Do we still need a newsletter if lifecycle messaging exists?
- Yes, for what lifecycle cannot do: sharing what is new, an opinion, a story. The newsletter is a relationship with the whole list; lifecycle messages are conversations with individuals about what they did. They are different jobs and both worth doing.
- How do we avoid customers getting too many messages?
- A frequency cap per customer across all journeys, a priority order when journeys collide, and a suppression rule for anyone with an open complaint. Enforce these in the platform, not in each journey, so they hold as journeys multiply.
- Which event should we build first?
- The one closest to revenue with the most volume — abandoned cart for a store, trial expiry for software, quote sent for services, missed appointment for a clinic. One journey done well proves the model; the rest follow the same pattern.
