The Reality of Retention

Your Team Is Built to Create Campaigns. Not to Monitor Infrastructure 24/7.

×

Human eyes miss silent logic errors

Even your best lifecycle marketer can't manually check every data property sync, webhook, and Liquid logic branch across dozens of active workflows. Fields get deprecated. Event payloads stop firing after a product update. Automations break silently — and your team won't know until the revenue drop shows up weeks later.

×

A manual audit is obsolete the next day

Hiring a specialist to audit your workspace costs $1,500 or more. But a manual audit is a snapshot — frozen in time. The moment your engineering team pushes a product update or changes a user event, new leaks open up immediately. You're paying for a report on what was broken last month.

×

Finding leaks after users churn is too late

If you're waiting for a quarterly review to catch a broken onboarding flow, hundreds of trial users are bleeding out in the meantime. By the time a human spots the error, those users have already moved to a competitor. The leak doesn't pause while your team schedules a review.

The Math

24/7 Protection for Less Than a Single Manual Audit.

A traditional consultant charges $1,500+ for a one-time workspace review. It takes weeks to schedule, days to complete, and the report is outdated the moment your team ships the next product update. Perennus runs a full diagnostic every 6 hours — 1,460 scans a year — for $199/month.

What Perennus Monitors

Six Pillars of Lifecycle Health. Scanned Every 6 Hours.

List Hygiene

Invalid addresses, suppression gaps, segment decay. The ceiling on every email you send.

Deliverability

Bounce rates by provider, domain reputation, authentication status. Whether your emails reach the inbox.

Onboarding

Activation rates, trigger coverage, time-to-value gaps. Where new signups stop becoming customers.

Engagement

Open and click trends, fatigue signals, send frequency. Whether your audience is still listening.

Re-engagement

Win-back performance, sunset policies, churn risk. Whether lapsing users are recovered or lost quietly.

Trigger Integrity

Broken automations, stalled queues, event payload failures, timing drift. Whether your workflows are actually running.

Testimonials

"What impressed me most was the depth of his thinking around retention. Instead of jumping straight into tactics, he analysed our entire customer journey and connected that with lifecycle messaging in a way that made complete sense."

"Isaac turned what felt like a messy problem into a clear system. He mapped our onboarding journey, showed us exactly where users were dropping off, and delivered email flows ready to launch immediately."

From a single workspace scan: 66,000 contacts analyzed. 32% invalid emails identified. 74% inactive contacts flagged. A broken behavioral trigger silently queuing 174,000 emails — zero delivered. That same diagnostic framework now runs inside Perennus, automatically, every 6 hours.
