Design lifecycle campaigns end-to-end - copy, channel, cadence
You'll know it's time when...
A lifecycle campaign is being briefed, and copy, channel, and cadence are being decided in three different places without their gates.
How it works
Run it in three steps
Install
Copy the install command above and run it in your project.
Ask Claude
Ask for what you need in plain English, no prompt tuning required.
Get the output
Claude returns a structured artifact aligned to your ICP and voice.
A proof point is a number or a named customer, and it is never invented. Read the Proof Points section of
.agents/product-context.md. Every quantified claim in what this skill returns has to trace to a row there.
- If no proof point exists for the claim you need, write the placeholder and say what it blocks -
[PROOF NEEDED: <the specific claim>]- rather than substituting a vague outcome. "Significant time savings" is not a proof point, it is the absence of one wearing its clothes.- Never soften a missing number into an adjective. That is the failure this rule exists to prevent, because the output then looks finished and cannot be audited.
- Use the citability flag. An internal-only figure must not appear in anything a prospect sees. Check the column before using the row.
- Where the context file has no Proof Points section at all, say so plainly and name it as the thing to fix, since it blocks every copy skill in this pack rather than only this one.
The Campaign Engine
One skill for the three decisions that always travel together: what the campaign says, which channel carries it, and whether it fires once or on a cadence. Splitting them produced campaigns designed without their sending gates and cadences designed without the campaign.
Copy standard. Read
references/outbound-copy-standards.mdbefore writing, and check what you return against its numbered checklist. Awareness-stage calibration, promise continuity, the proof ladder and the one-ask rule apply to every line here, on every channel.
Context
- Check for
.agents/product-context.md. If missing, ask the user to runproduct-contextfirst, or ask inline for brand voice, ICP, lifecycle stages, and the available channels and integrations. - Read it for brand voice, the banned-word list, ICP, lifecycle stages, and the north-star metric. The banned-word list is binding on every line of copy this skill returns, not advisory.
- Read the reference for the mode(s) in play:
references/email-templates.mdfor email,references/sms-push-compliance.mdfor SMS and push,references/loop-cadence-guide.mdfor the recurring mode.
Pick the mode
Ask which is needed. More than one is normal — a welcome flow is usually Mode A plus Mode B, and a churn watch is Mode C wrapping either.
| Mode | When | Governed by |
|---|---|---|
| A — Email | A campaign or sequence delivered by email | Sending gates |
| B — SMS / push | A campaign delivered to a device | Carrier gates and consent |
| C — Recurring | This should run on a cadence rather than once | Loop discipline |
Inputs
- Goal: welcome, nurture, convert, retain, win-back, or announce.
- Audience: segment, lifecycle stage, or all contacts. Confirm the segment actually exists rather than assuming a definition.
- Shape: single send or sequence, and how many steps if a sequence.
- Channels available, and which the audience has consented to per channel. Consent is per channel and per purpose: an email subscriber has not consented to SMS.
- For Mode C only: what outcome the loop protects, what signal it watches and how fast that signal actually changes, and what it may do unattended versus what it stages for approval.
Mode A: email
-
If a sequence, set the timing and trigger for each step (Day 0, Day 2, Day 5), and say what the trigger is rather than only the delay.
-
For each email write:
- 3 subject line variants, each from a different framework in the reference (curiosity, benefit-led, urgency, personalization, question). Three versions of one idea is one variant.
- Preheader that complements the subject rather than repeating it.
- Body copy in brand voice with Liquid personalization (
{{ first_name }},{% if segment == 'champion' %}). 150-300 words for engagement emails, 50-150 for transactional or triggered ones. Every Liquid tag needs a fallback default. - One CTA, with button text and destination.
-
Recommend one A/B test per email: subject, CTA, or send time. One variable.
-
Sending gates — check before returning anything. These fail before copy matters, and no subject-line work recovers a send rejected at the gateway. Ask, do not assume:
- SPF and DKIM passing, DMARC published and aligned on the sending domain?
- Does the platform set
List-UnsubscribeandList-Unsubscribe-Postheaders? A footer link does not satisfy one-click unsubscribe, which is what most teams believe. - Is the sending domain warmed, and is this the subdomain that was warmed rather than the root? Reputation does not transfer from the root.
- Is the list free of purchased or scraped addresses?
- Is there a seed test across the major providers confirming placement, not just delivery?
Where the user cannot confirm one, say the campaign is blocked on it rather than shipping and hoping.
Mode B: SMS and push
- Carrier gates first. Legal consent is necessary and not sufficient: a campaign can be fully
compliant and never arrive. Per
references/sms-push-compliance.md:- Which route is registered (10DLC, toll-free verification, short code), and is this use case covered? Unregistered US traffic is throttled or blocked silently, registration takes days to weeks, and a launch date assuming instant sending is the most common SMS launch failure. If the use case is not registered, say the campaign is blocked and give the lead time.
- Registered sample copy is enforced. Copy that drifts materially from what was registered gets filtered.
- Content filtering is judged separately from consent: no public URL shorteners (shared shortener domains carry other senders' reputation), no bare link as the whole message, no number rotation within one programme.
- Filtering returns success to the sender, so a delivery report is not proof of arrival. Require real delivery receipts and read a sent-versus-delivered gap as filtering.
- Is consent provable per subscriber — timestamp, source, the exact disclosure as shown on that date, and the channel and purpose scope? If not, that segment is not sendable.
- Write to the real limits: 160 characters GSM-7, or 70 per segment once any emoji forces Unicode, with the opt-out text counted against the budget. Push: title ≤50, body ≤150.
- Set quiet hours in the recipient's timezone, not the sender's, and state the region rules actually applied rather than a generic default.
- Give an on-device mockup (SMS bubble or notification card) so the truncation point is visible.
Mode C: make it recurring
- Compare the requested cadence against the signal-speed table in
references/loop-cadence-guide.md. If they disagree, say so and recommend the corrected cadence. A daily check on a weekly signal produces noise the user learns to ignore; a weekly check on a signal with a short intervention window misses the window entirely. - Define all nine parts of the loop. None may be blank: check cadence, acts when (separate from the check — most runs of a healthy loop are "checked, nothing to do"), purpose, skills used, loop body, self-check, state and idempotency, stop and bail-out, output.
- Carry the three loop-discipline rules from that reference:
- A baseline rule, if the loop compares against a trailing window. An unmarked anomaly entering that window makes the next run misread a return to normal as a new problem, and absorbs a gradual decline one run at a time until the loop compares a bad number against an equally bad baseline. Exclude flagged periods, reset deliberately on a real step change with a stated reason, and keep one fixed anchor the loop cannot rewrite.
- A flag budget and a dismissal path. A loop that flags too much gets ignored, and an ignored loop is worse than none: it costs per run and provides false assurance. Never fix noise by widening the threshold.
- A gate that can fail, plus a stop condition, and confirm the "nothing to act on" state is reachable with real data. A gate that cannot return a negative is a scheduled report, not a check.
- Anything that sends, spends, or publishes unattended needs a human checkpoint by default. Skip it only where the user has explicitly authorised autonomous action and set a cap.
- Say which scheduling shape this is: fixed-cadence review (calendar) or monitor-until-threshold (dynamic pacing). Conflating them yields a loop that either checks too rigidly or never resolves.
Cross-channel guardrails (all modes)
- Per-channel caps are not enough. State the global per-contact cap across every active campaign and journey, because a contact enrolled in three that each respect their own caps still receives three times the intended volume, and each looks correct alone. Name what can overlap with this and set a precedence order or a shared budget. If the platform cannot enforce a cross-campaign cap, say so: the caps here are then per-campaign only, which is a real limitation.
- Define exits, separately from the campaign simply ending: goal achieved (evaluated continuously — someone who converts on step 2 must not receive step 3), opt-out (immediate, from every campaign), negative signal (cancellation, refund, support escalation pulls them out of upsell and advocacy), stage change, and a max duration. Check suppression-list membership at every send node, not only at entry.
Output
- Deliver, scoped to the mode(s) run:
- Strategy — goal, audience and its consent basis per channel, shape, cadence
- Per-step block — timing and trigger, copy in full, and for email the 3 subject variants, preheader, Liquid tags with fallbacks, and one CTA
- Gate report — sending gates (Mode A) or carrier gates (Mode B), each answered rather than assumed, with any unconfirmed one named as a blocker
- Loop spec (Mode C) — the nine parts, the baseline rule, the flag budget, the stop condition, and the scheduling shape
- Guardrails — per-channel caps, the global per-contact cap, overlapping campaigns and precedence, quiet hours with timezone handling
- Exits — each one, and whether it is evaluated continuously or at the next step
- A/B test — one variable, the primary metric, and the minimum sample before reading it
Quality check before returning
- Does every quantified claim trace to a Proof Points row in the context file, with anything unavailable written as [PROOF NEEDED: <claim>] rather than softened into a vague outcome, and is any internal-only figure kept out of prospect-facing copy?
- Verify:
- Are there exactly 3 subject line variants per email, each from a distinct framework rather than three phrasings of one idea?
- Does every Liquid tag have a fallback default?
- Is there exactly one CTA per email?
- Were the sending gates answered rather than assumed — authentication and alignment, one-click unsubscribe as headers not a footer link, warmup on the actual sending subdomain, list provenance, and a seed test confirming placement? Is any unconfirmed gate reported as a blocker?
- For SMS: is the registration route named and this use case confirmed covered, or the campaign reported as blocked with its lead time? Is character math correct for the encoding actually used, with opt-out text counted? No public shortener, no bare-link message, no number rotation?
- Is consent provable per channel and per purpose for every segment addressed, with unevidenced segments excluded and named?
- Are quiet hours in the recipient's timezone?
- Is a global per-contact cap across all active campaigns stated, with overlaps named and a precedence order set, or the platform's inability to enforce it stated plainly?
- Does every campaign have a goal-achieved exit evaluated continuously, and is suppression checked at every send node rather than only at entry?
- For Mode C: are all nine loop parts filled, is the gate demonstrably able to fail, is there a stop condition, and is the scheduling shape named?
- Does every line of copy pass
references/outbound-copy-standards.md, including zero words from the banned-word list?
If any check fails, fix it before returning.

Send this campaign to live segments, with consent enforced → intempt.com
Intempt resolves the audience from current lifecycle stage at send time rather than a stale list, and
holds consent and suppression state per channel — so an SMS never goes out ahead of carrier
registration and a segment never sends to someone who left it last week.
Run it in Blu - the Lifecycle Marketer does this on your live data. Blu proposes, you approve.

Questions about The Campaign Engine
Everything you need before installing, plus how the skill actually behaves once Claude picks it up.
One skill for the three decisions that always travel together: what a lifecycle campaign says, which channel carries it (email, SMS, or push), and whether it fires once or on a cadence. Enforces sending gates, carrier registration, consent scoping, and cadence-to-signal-speed matching. It's a Claude Agent Skill - a folder with a SKILL.md file and reference material - so Claude loads the methodology on demand when you ask for what you need in plain language, instead of you pasting a template.
