The 6 leak points

Six places subscription businesses lose revenue after signup.

Every scan checks the same six stages — from signup to silent churn — and prices what's leaking at each one.

01

List Hygiene

Dead contacts and rising bounce rates destroying sender reputation before you see the revenue drop.

Recent scan: 18% of contacts unsubscribed but still in 3 active segments — $12,600/yr compliance risk.
02

Onboarding

New signups that never activate because the first seven days weren't engineered. Often the single largest leak.

Recent scan: Zero new contacts in 30 days with a welcome sequence. Every unsupported signup is a silent churn event.
03

Engagement

Messaging that stopped resonating — opens and clicks fading long before anyone thinks to check.

Recent scan: 0 human clicks across 4 active campaigns. 140+ emails sent with zero downstream conversion.
04

Deliverability

Gmail, Yahoo, and Outlook placement failures that cap your revenue no matter how good the email is.

Recent scan: 56.3% Gmail bounce rate — sender reputation degrading with every send.
05

Re-engagement

Lapsed customers with no win-back path — quietly written off instead of recovered.

Recent scan: 34% of contacts inactive 90+ days, no win-back sequence — $4,200/mo left on the table.
06

Trigger Integrity

Broken or looping automations that silently send nothing, send the wrong thing, or never fire at all.

Recent scan: 174,000 sends queued for a 66K list — broken trigger looping at 3× the list size.
