The SaaS 50 — Decision Protocols for Retention & Profitability

What's Inside

5 stages. 50 rules. Full SaaS lifecycle coverage.

From first signup to win-back, every critical decision point is covered by a deterministic protocol.

01

Acquire & Activate

Rules 43–50

How to Read Each Rule

Not checklists. Decision protocols.

Each rule is an EMU — an Executable Memory Unit. A self-contained decision protocol with explicit conditions, actions, and safety controls. Authored once, enforced forever.

EMU Key Unique identifier: domain.category.action

Trigger Conditions that must ALL be true for the rule to fire

Intent What the rule does and why it matters

Priority 1–10 scale. Higher priority wins conflicts.

Cooldown Min time between firings per user. Prevents harassment.

Sequencing Rules that must fire before this one. Never blindside a user.

Stage 1: Acquire & Activate

The window where most SaaS products lose users permanently. These 5 rules cover signup through first value.

01

Trigger

New account created, email verified, no onboarding events recorded yet.

Intent

Initiate the onboarding sequence with personalized getting-started guidance based on plan type and stated use case. Fires exactly once per account.

02

Trigger

User created an instance/workspace but hasn't completed payment after 4+ hours. No checkout reminder sent in last 3 days.

Intent

Send checkout reminder with incentive to complete signup. Captures users who got distracted mid-funnel.

03

Trigger

User completes checkout within 24 hours of receiving a checkout reminder. No recovery bonus awarded in last 90 days.

Intent

Reward users who respond to the nudge. The 24-hour event window acts as a natural expiry — the rule stops matching after the reminder event ages out.

04

Trigger

Account is active/provisioned but has zero usage records. No activation nudge sent in last 7 days.

Intent

Send getting-started guidance to users who signed up and paid but haven't actually used the product. The highest-leverage retention email you'll ever send.

05

Trigger

User completes first meaningful action (first API call, first project created, first integration connected). No milestone acknowledgment sent yet.

Intent

Celebrate first value moment and guide toward second. Reinforces the behavior you want repeated.

06

Trigger

Account older than 48 hours, required setup steps incomplete. No setup reminder sent in last 5 days.

Intent

Prompt users to complete critical setup steps that correlate with long-term retention.

07

Trigger

Account is single-user, plan supports multiple seats, user has been active for 3+ days.

Intent

Multi-user accounts churn at dramatically lower rates — this is a retention play disguised as onboarding.

Why Decision Protocols

Rules that enforce themselves

These aren't items on a product backlog. They're deterministic protocols that evaluate, decide, and act — with built-in safety controls.

Sequencing over escalation

Critical actions like suspension always require a prior warning event. Users are never blindsided by an enforcement action.

Cooldowns prevent harassment

Every user-facing rule has a minimum interval. No user receives the same communication twice within its cooldown window.

Priority resolves conflicts

When multiple rules match, higher priority wins. Billing enforcement (7–9) always takes precedence over engagement nudges (2–4).

Implement all 50 rules in hours, not months

Memrail's code agent can author every EMU in this playbook, validate it through integration completeness checks, deploy through shadow mode, and promote to production. The full pack, stood up in days.

Case Study

How HostedShell.com governs their SaaS lifecycle with decision protocols

HostedShell provides hosted OpenClaw instances for developer teams. With 20 EMU rules from this playbook, they automated their entire billing, onboarding, and retention lifecycle — no AI involved. Pure deterministic decision governance.

Rules fire on real events: signup, payment, usage thresholds, dormancy. Every action is traced, every communication is cooldown-governed, and every suspension requires a prior warning.
