Build an ecommerce email marketing calendar with campaign topics, audience segments, subject lines and draft messages. Email Campaign Writer uses your products, brand voice and approved offers to plan a 30-day schedule covering welcome, abandoned-cart, post-purchase and win-back messages, ready for your team to adapt in its email platform.
Start with the month's commercial priorities: which products need attention, which offers are approved and which customers should receive them. The Skill turns that brief into a campaign calendar and develops the subject, message and next action for each audience.
It is useful when the team has promotion ideas but no coherent sending plan. Drafts and timing recommendations are delivered as planning material; list selection, automation setup and sending happen in your email platform.
The calendar connects audience, message and timing instead of listing isolated promotions. Welcome messages introduce the store, post-purchase messages support product use, and win-back messages address a different customer situation.
Develop a full month, an abandoned-cart series or subject-line alternatives from the same brief. Product claims, discounts and customer proof come from your approved material, keeping campaigns consistent when several teammates edit them.
Brand voice, products, approved offers, audience segments, and verified past campaign results.
A model chat is enough to draft from these instructions. Real system access or file changes need separately configured tools.
No email platform connection or sending code is included. Sample scarcity, customer counts, and expected rates must not become unsupported claims.
Use these instructions in a chat, or ask Codex / Claude Code to save them as a personal Skill for repeated tasks.
Set up a personal reusable instruction template for Email Campaign Writer in the app I am using.
1. Read the “Collected instruction template” section at https://ecomagenttools.com/skills/email-campaign-writer. Use only that complete instruction text, not the page’s reviews, FAQ or installation explanation. If you cannot retrieve the complete text, ask me to paste it; do not guess it or download a same-named third-party package.
2. Show which assumptions, placeholders and access requirements I need to supply. Preserve the collected task instructions. This is a locally adapted template, not an original-author package.
3. If you are Codex or Claude Code with local file access, create a personal Skill named email-campaign-writer-local under ~/.agents/skills/email-campaign-writer-local/SKILL.md for Codex or ~/.claude/skills/email-campaign-writer-local/SKILL.md for Claude Code. Add valid name and description frontmatter if absent; keep the collected instructions in the body and identify the local adaptation. Do not overwrite an existing Skill. If you are in a chat-only app, use these instructions in the current conversation instead and do not claim a local installation.
4. Return the saved path or current-chat setup result and a starter request for this task. List any required tools or data that remain unconfigured. Do not claim account/API access or a completed business workflow just because the template was saved.Network-collected; no confirmed author source. The collected text was reviewed, but it has not been linked to a verified original publication. This does not establish that no official package exists; the examples here use only the collected text.
You are an ecommerce email marketing strategist and copywriter. When given a product category and brand description, you will:
1. Generate a 30-day email calendar covering:
- Welcome series (3 emails: Day 0, 2, 5)
- Browse abandonment (Day 1 after browse)
- Cart abandonment (3 emails: 1h, 24h, 72h)
- Post-purchase (2 emails: Day 7, 21)
- Win-back (30+ days inactive)
- Weekly newsletter / promotion
2. For each email, provide:
- Subject line (with emoji)
- Preview text
- Full body copy
- CTA button text
- Recommended send time
- Target segment
3. Apply these principles:
- Personalization: use {first_name}, {product_name}, {cart_value}
- Scarcity when genuine: "Only 3 left in your size"
- Social proof: "Join 50,000+ happy customers"
- A/B test subject line variants
4. Include performance benchmarks:
- Expected open rate for each email type
- Expected click rate
- Industry average for comparison
Output format: Markdown calendar with clear email separators.Starter prompts for the main use cases—copy and use them directly.

Case input files: business-inputs.zip
Use the email-campaign-writer Skill.
Plan our next 30 days of lifecycle email. Write all 14 messages with subjects, preview text, complete bodies and a single CTA each. Coordinate welcome, cart recovery, post-purchase and newsletter messages; define frequency caps, purchase exits and support exclusions. Use our supplied historical benchmarks to set realistic review priorities.
The attached business materials are:
- inputs/brief.json
- inputs/supplemental-benchmarks.json
Deliver a complete result.md report that the operations team can read, plus any finished files needed for this task. Keep supporting calculations and evidence with the deliverables. Write the report in English; use the requested target language for customer-facing copy. The business datasets are fictional examples unless the brief explicitly names a live public website.The primary file produced by this prompt is shown below in its original language.
Decision: Run 14 email assets across November 3–December 2, 2026, inclusive, in America/New_York. These are conditional flows and four weekly newsletters, not 14 sends to every subscriber. Customer copy is en-US. All merchant data and benchmark figures supplied for this exercise are synthetic. No emails have been sent and no performance improvement is claimed.
The plan uses the $24, 500ml insulated stainless steel mug without discounts, inventory urgency, review quotes or customer-count claims: none has supporting evidence. The campaign starts on the supplied date; do not backfill missed sends if activation occurs later.
| Asset | Schedule | Purpose |
|---|---|---|
| W1 | Opt-in Day 0 | Introduce the mug and terms |
| W2 | Opt-in Day 2 | Answer product, care and shipping questions |
| W3 | Opt-in Day 5 | Help a nonbuyer decide |
| B1 | 24 hours after qualifying product browse | Offer another look |
| C1 | 1 hour after cart inactivity | Restore the cart |
| C2 | 24 hours after cart inactivity; hour 25 if C1 sent at hour 1 | Explain shipping |
| C3 | 72 hours after cart inactivity | Final cart reminder |
| P1 | 7 days after confirmed delivery | Explain care |
| P2 | 21 days after confirmed delivery | Check in |
| R1 | November 26, for contacts inactive 30+ days | Reintroduce the mug |
| N1 | November 6, 10:00 | Daily coffee or tea routine |
| N2 | November 13, 10:00 | Care reminder |
| N3 | November 20, 10:00 | Shipping threshold explanation |
| N4 | November 27, 10:00 | Gift consideration without arrival promises |
For example, a November 3 opt-in receives welcome candidates on November 3, 5 and 8. A November 3 confirmed delivery generates post-purchase candidates on November 10 and 24. Each candidate still requires the checks below. Later entrants may have steps falling after December 2; those are outside this campaign window and must be reviewed for the next cycle. Existing entrants may receive in-window steps based on their true event dates; never replay already-sent steps.
Cap example: If C1 sends at cart hour 1, C2 cannot send at hour 24 because only 23 hours have elapsed. Its earliest slot is hour 25. C3 may send at hour 72 if quiet hours and the rolling seven-day count permit it. Those three sends consume the entire three-per-seven-day allowance; a newsletter is skipped. If earlier marketing has already used the allowance, cart also waits or expires—priority never overrides the cap.
Known return case: The supplied unopened-item request was made 14 days after delivery. It appears eligible for review within the 30-day unused-item window, but a refund is not approved by this plan. Keep the contact suppressed while Mia handles the request and Alex reviews any final refund. Its nominal delivery+21 check-in would fall on November 10 and must be excluded while the case is open. Never turn a return request into a win-back or cross-sell opportunity.
The supplemental file supplies planned email rates and a synthetic “industry comparison.” Neither file contains historical email sends, delivered counts, opens, clicks, conversion rates, unsubscribes or complaints. Therefore the table below is a planning reference, not a forecast validated by history or a measured industry average. Expected rates here mean the supplied planning assumptions, shared by all messages of that type.
Define open rate as unique recipients with a recorded open / delivered emails; click rate as unique recipients clicking a primary product/cart CTA / delivered emails. Exclude footer clicks, filter bot activity where supported, and do not treat click rate as click-to-open rate. Confirm these definitions match the platform before comparing results. Privacy-related opens make opens directional.
| Type / IDs | Planned open | Planned click | Synthetic comparison open / click | Difference, percentage points open / click | Review focus |
|---|---|---|---|---|---|
| Welcome W1–W3 | 45% | 4% | 35% / 2% | +10 / +2 | Entry quality, welcome-to-purchase path |
| Browse B1 | 38% | 3% | 35% / 2% | +3 / +1 | Identification and browse/cart suppression |
| Cart C1–C3 | 42% | 5% | 35% / 2% | +7 / +3 | First: exits, caps, cart links and checkout completion |
| Post-purchase P1–P2 | 40% | 3% | 35% / 2% | +5 / +1 | First: delivery anchors and support exclusions |
| Win-back R1 | 30% | 2% | 35% / 2% | −5 / 0 | Lower priority: consent, inactivity quality and complaints |
| Newsletter N1–N4 | 35% | 2.5% | 35% / 2% | 0 / +0.5 | Engagement and broadcast collision checks |
The only supplied historical business comparison is weekly store activity: orders 100→120, sessions 4,000→4,800, gross sales $2,400→$2,880, refunds $120→$144 and ad spend $300→$360, all up 20%. Average order value stays $24, orders per session stays 2.5%, refunds/gross stays 5%, and ad spend per order stays $3. Gross less refunds rises $2,280→$2,736. These show scale growth with flat ratios; they do not demonstrate better email performance or an email-driven sales lift. Gross per ad dollar is 8 in both weeks, an aggregate ratio rather than attributed advertising ROAS.
At $24 per mug, two mugs total $48 and do not qualify for free shipping; three total $72 and do. Illustrative one-unit contribution is $17 including the $5 shipping collection, after $8 unit cost and $4 merchant shipping cost, before taxes, fees, returns and advertising. Without shipping collection it is $12. This is arithmetic using the supplied per-order assumptions, not realized profit or a multi-unit shipping-cost model. Keep the campaign at full price; there is no approved offer or measured basis for a discount.
Every message below has two subject variants. Keep body, preview, timing and eligibility identical. Start with a 50/50 persistent random split of eligible contacts within each flow; broadcasts retain stable contact assignment. Do not resend to non-openers. With no list size or baseline variance, do not promise statistical significance. Test W1 first, then C1 if volume supports it; use A for the other assets until enough eligible volume exists. Select a winner using primary CTA click rate, while monitoring purchase outcomes and unsubscribes. Report counts and uncertainty; a small difference is inconclusive. Email-attributed orders are descriptive and are not proof of incremental lift without a separately designed holdout experiment.
All bodies below are complete apart from required personalization and merchant-owned URLs/contact details. Append the exact shared footer shown after the messages to every body. Each message has one promotional CTA button; preferences and unsubscribe links are mandatory utility links. Reply invitations are support access, not extra promotional buttons. No images or extra product links are required.
