Frequently asked questions

How should billing systems and email platforms divide work?

Billing systems record truth and execute mechanics (trials, renewals, retries, proration); email platforms read those states for timing while owning all persuasion. Dunning configuration lives in billing; dunning communication strategy lives in lifecycle. Confusing the layers starves both jobs — wire webhooks before building journeys.

Evaluate billing vendors on mechanics and economics, journey platforms on timing and exits — never cross the criteria.

What is the difference between pause and cancellation handling?

Pauses preserve relationships with return paths (duration options, keep-warm content, frictionless resume); cancellations end billing with dignity and timed win-back. Pause-friendly journeys retain multiples of save plays because they honor customer reality instead of fighting it. Design pause paths explicitly rather than improvising at cancellation.

Measure pause-to-return rates separately; they justify pause features against finance skepticism.

How much involuntary churn should subscriptions expect?

Failed payments silently end 2–9% of subscriptions monthly depending on customer mix and retry sophistication. Native dunning typically recovers half or more of at-risk involuntary churn — the highest-ROI email program per hour invested, installed once and compounding forever. Distinguish involuntary from voluntary churn in reporting always.

Dunning configuration belongs in billing; dunning communication belongs in lifecycle journeys reading billing states.

Should support cases pause subscription marketing?

Absolutely and automatically: customers with open cases need human resolution, never promotional pressure. Suppression must trigger on case creation and lift on confirmed resolution — manual processes miss cases at volume. Promotion during support crises reads as institutional contempt and churns otherwise-savable accounts.

Test suppression with seeded support states quarterly; untested exits fail silently.

How do you win back cancelled subscribers?

With elapsed-time respect and genuine new value: immediate exit surveys with pause alternatives, 60+ day win-back with product proof relevant to cancellation reasons, launch-triggered outreach for major releases. Never drip cancelled subscribers on schedules; pressure converts once and poisons brand perception permanently.

Measure win-back against never-mailed controls so hope never substitutes for evidence.

How do you measure subscription email honestly?

Activation rate, renewal rate, involuntary-churn recovery, pause-to-return conversion, win-back recovery, and net revenue retention — each against holdouts with revenue attributed. Mail metrics diagnose deliverability only. Report per segment; consumer, SMB, and enterprise subscriptions share neither dynamics nor benchmarks.

Cohort retention curves tell the subscription truth no snapshot can.
