The lifecycle runs on a timer, or it doesn’t exist.

The problem

Why it happens.

Onboarding fires on day one, three and seven, whatever the user did. A trigger misfires and nobody sees it. Deliverability quietly decays. Or leads arrive and nothing carries them to a purchase at all.

Better emails don’t fix any of that. The system has to respond to what customers actually do.

Two ways in

Rebuild what exists, or build from zero.

What Perennus does

The work.

1. Fix the foundations first

   Authentication, list hygiene, suppression logic, data and the rules for which system owns which relationship.

2. Build around behaviour, not the calendar

   Onboarding and activation, conversion moments, re-engagement and win-back, branching on what customers actually do.

3. Write the strategy before the flows

   Objectives, triggers, audiences, behavioural conditions, exit criteria and deliverability rules, reviewed and approved before implementation.

4. Implement in your stack

   In the platforms you already run. Our case work spans Customer.io, Beehiiv, GoHighLevel, Typeform and Zapier.

5. Benchmark and hand back

   Every flow gets a benchmark, and your team gets the documentation to run the system.

Who it’s for

A good fit when…

• Companies with a Diagnostic in hand, ours or their own, and a clear view of what’s broken
• Teams whose lifecycle was built once and never revisited
• Businesses with traffic and signups but no system between the first click and the first purchase

The engagement

What it looks like.

1. 1Diagnosis
2. 2Strategy
3. 3Build
4. 4Benchmark and handoff

A project with an agreed scope. Where there’s no recent diagnosis, it starts with one.

Length depends on the scope: the AI companion rebuild ran for six weeks, and larger systems run longer.

Deliverables

What you get.

• Fixed infrastructure: authentication, list hygiene, suppression and ownership rules
• A lifecycle strategy document, approved before build
• Live, behaviour-driven flows in your platform
• A benchmark for every flow
• SOPs and a handoff guide your team can run from

What happens after

Afterwards.

• Your team runs the system from the documentation we hand back.
• Or continue with a Lifecycle Partnership and keep improving it together.
