Lifecycle email
Lifecycle email: the automated messages that carry the load
A broadcast goes to everyone at once. A lifecycle email goes to one person at the right moment, triggered by where they are in their journey. For most software companies, lifecycle email quietly does more work than any campaign, because it runs forever once it is set up and always arrives in context.
How lifecycle email differs from campaigns
A campaign is a single send you schedule: a newsletter, an announcement, a promotion. A lifecycle email is automated and event-driven. It fires when a contact does something, or fails to do something, rather than when you press send. Campaigns time a message to your calendar. Lifecycle email times a message to the person.
The core lifecycle emails
Welcome. The first message after signup, with the highest open rate you will ever see. Use it to set expectations and point to one clear next step.
Onboarding. A short series that helps a new user reach the moment the product clicks. Tie each message to a step, not to a fixed day.
Activation nudges. Triggered when someone signs up but has not done the key action yet. The trigger is the absence of an event, which is where automation earns its keep.
Engagement and education. Ongoing messages that surface features or use cases based on what a user has and has not done.
Retention and renewal. Reminders tied to trial endings, usage limits, or billing, sent before the moment rather than after.
Re-engagement and win-back. A focused sequence for contacts who have gone quiet, with a clear path back and a sunset if they do not return.
What makes them fire: events
Lifecycle email is only as good as the signals it listens to. The useful triggers are product events: account created, project started, invite sent, plan upgraded, key feature used. When your app reports these, you can send the message that matches the moment instead of guessing from a calendar.
How to build lifecycle email in Loops
In Loops, lifecycle email runs through Workflows, a visual builder where you set a trigger, then branch with timers, conditions, and emails.
Send events from your app with the Events API, or trigger on a contact being added, a property changing, or joining a list.
Build the flow on a canvas with trigger, email, timer, audience filter, branch, and experiment nodes.
Personalize each message with contact and event data, with fallback values so nothing renders blank.
Measure on the workflow goal and adjust the path over time.
Because the messages send themselves once live, lifecycle email compounds: every new signup walks the same well-tuned path. For the product side, see product and lifecycle email in Loops.
