Design a lifecycle email sequence

Email teams often lack a clear lifecycle map and send too frequently. This skill creates flow plans with timing, exits, and safeguards before copywriting begins.

Agent request
Review the Skillstore skill "email-sequence-designer" from https://skillstore.io/skills/aaron-he-zhu-email-sequence-designer.md and its manifest at https://skillstore.io/api/skills/aaron-he-zhu-email-sequence-designer/manifest.

Test it

Using "email-sequence-designer". Design a welcome flow for a subscription fitness app.

Expected outcome:

  • Trigger: completed account signup.
  • Step 1: send immediately with setup guidance; exit on first workout logged.
  • Step 2: send after two days to inactive users with a workout recommendation.
  • Guardrail: maximum two lifecycle emails in seven days.

Using "email-sequence-designer". Create an abandoned-cart sequence with a discount branch.

Expected outcome:

  • Trigger: cart inactive for one hour.
  • Step 1: send after one hour with cart reminder; exit on purchase.
  • Step 2: send after 24 hours; show discount only to non-purchasers.
  • Sunset: stop after step three or an unsubscribe, bounce, or suppression event.

Security Audit

Most static findings are false positives caused by Markdown code fences and relative documentation links. Two risks remain: the Resend shell example lacks safe handling for supplied values, and the save filename is derived from a flow or goal without a stated sanitization rule.

These are real local capabilities that may be expected for this skill, so they require review but are not counted as confirmed malicious behavior.

High
Path traversal sequence
On user confirmation, save to `memory/email/email-sequence-designer/YYYY-MM-DD-<flow-or-goal>.md` β€”
The output filename includes the flow or goal placeholder without a stated filename allowlist or path normalization. A crafted value could escape the intended memory directory if an implementation interpolates it directly.
Medium
Ruby/shell backtick execution
**Zero-dependency flow activation (when Resend is the ESP)**: once a flow step's creative is approve
The skill directs a shell invocation whose segment identifier and message fields are placeholders for user-controlled values. It provides no safe argument construction or validation guidance, creating a command-injection risk when copied into a shell.

What You Can Build

Plan a welcome journey

Create a triggered onboarding sequence with progressive goals, timing, and exits for new subscribers.

Reduce abandoned-cart friction

Design a cart recovery flow with discount branches, purchase exits, and frequency limits.

Control list fatigue

Set cadence rules, quiet hours, and sunset thresholds across overlapping campaigns.

Try These Prompts

Beginner: welcome flow
Design a three-step welcome flow for a skincare brand. The trigger is newsletter signup. Include timing, goal, and exit conditions.
Intermediate: cart recovery
Build an abandoned-cart sequence for our online store. Use three steps over five days, an exit on purchase, and a discount branch.
Advanced: cadence governance
Map our welcome, cart, post-purchase, and re-engagement flows. Set global caps, quiet hours, fatigue rules, and a sunset policy.
Expert: B2B outbound lifecycle
Design a cold-outbound sequence for mid-market IT buyers. Include reply exits, role-based branches, send windows, and a SEND N score.

Best Practices

  • Confirm the trigger source and target segment before finalizing enrollment rules.
  • Use explicit conversion, reply, bounce, and unsubscribe exits in every relevant flow.
  • Apply one global send cap across flows to prevent overlapping messages.

Avoid

  • Do not send all recipients through the same flow without lifecycle segmentation.
  • Do not continue a sequence after a conversion, reply, unsubscribe, or bounce.
  • Do not treat a re-engagement branch as consent to resume mailing indefinitely.

Frequently Asked Questions

Does this skill write email copy?
No. It designs the flow structure. Use an email copywriting skill for subjects, bodies, and calls to action.
Can it plan an abandoned-cart campaign?
Yes. It can define cart triggers, delays, purchase exits, discount branches, and frequency safeguards.
Can it send emails through my provider?
It can document an optional Resend activation workflow, but sending requires your confirmation and valid consent controls.
What information should I provide?
Provide the lifecycle goal, trigger event, target segment, current flows, and any cadence or complaint data.
Does it handle unsubscribe compliance?
It includes unsubscribe exits in flow design, but a separate quality or compliance review should verify implementation.
Can it design win-back programs?
It can add a light re-engagement branch. Closed-loop re-consent programs for lapsed cohorts are outside its scope.
