About this skill

Email Copywriter

Writes send-ready newsletter, promotional, welcome and reactivation emails: subject lines, preheader, body and one CTA, mobile-first and in British English. Core principle: emails must earn the right to sell; value first, sell second.

Use When

  • We need this month's newsletter written for our customers or members.
  • A sale, launch or event needs a promotional email with a clear offer and one call to action.
  • New subscribers should get a welcome email that sets expectations and makes a first offer.
  • Lapsed customers need a reactivation email to bring them back.
  • Our open rates are low and we want subject line and preview text options to test.

Do Not Use When

  • 07-email-marketing-strategy for the lifecycle programme, segmentation and measurement plan.
  • direct-response-funnel-copy for multi-step sales sequences inside a launch funnel.
  • caption-writer for social post copy.
  • Stop before sending or scheduling in Mailchimp or any email platform, and before emailing anyone who has not opted in.

Required Inputs

Artefact Source/provider Required? If absent
Client business name (the inbox sender name), industry and country/city Client brief Yes Default the market to Uganda/East Africa; ask for the sender name before writing.
Email type (newsletter, promotional, welcome, reactivation) and primary goal (awareness, relationship, conversion, reactivation) Account manager or 07-email-marketing-strategy Yes Stop and ask; the structure depends on the type.
Audience segment (leads, active customers, lapsed customers, VIPs) and its opt-in status Client CRM or email platform export Yes Write for the named segment only; stop if the list's consent is unknown.
Key message (one sentence), offer or content to feature, and the CTA Approved brief Yes Draft the key message from the brief and flag the assumed CTA for confirmation.
Brand tone (3 words) and banned vocabulary 04-brand-voice-intake No Take tone from recent client emails and apply the engine's banned-word list.
Offer terms, prices, deadlines, testimonials and metrics Client source pack or authorised owner Conditional Hold urgency and social proof lines unless they are genuine and traceable.

The full intake list is in the email type templates.

Workflow

  1. Confirm the email type, segment, goal and sending boundary; route to 07-email-marketing-strategy for the lifecycle programme or to direct-response-funnel-copy for multi-step launch-funnel sequences.
  2. Inventory the offer facts, proof, deadlines and consent status; stop if the goal, segment or opt-in basis is unknowable.
  3. Pick 3 subject line approaches from the 12 subject line formulas that suit the type and audience, and write a preheader of 40–90 characters that extends the subject line rather than repeating it.
  4. Build the body to the type's structure in the email type templates: newsletter (value first, 150–250-word feature), promotional (desire-led hook, four-element offer, one proof line, 3 button options, genuine urgency only, PS), welcome (specific thanks, three what-to-expect bullets, first gift) or reactivation (honest acknowledgement, re-engagement hook, explicit opt-out).
  5. For welcome sequences, launches, waitlists, event promotion or reactivation flows, sequence the emails with launch and sequence copy; for premium or high-ticket offers apply premium-commercial-writing.
  6. Apply the writing standards (British English, sentences under 20 words on average, 2–3-sentence paragraphs, one CTA, written to one person, mobile-first, personal sign-off) and run the direct-marketing ethics filter on selling emails.
  7. Run the anti-ai-slop humanising passes and the quality checks below; correct any failing section and rerun the checks before delivery.
  8. Deliver send-ready copy with the claim register and the approval step; the client or an authorised owner schedules it.

Outputs

Artefact Consumer Acceptance condition
3 subject line options and 1 preheader Client approver; email platform operator Three genuinely different approaches; preheader 40–90 characters, complementing not repeating.
Email body with one CTA and personal sign-off Client approver Follows the type's structure; value before any ask; scannable on a smartphone.
CTA button options (promotional) and PS line Client approver Three action-led button texts; the PS restates the benefit differently or answers the likeliest objection.
Sequence copy, when requested 07-email-marketing-strategy owner Each email progresses the sequence; no two emails do the same job.

Evidence Produced

Evidence Format Acceptance condition
Claim, proof and urgency register Inline table Every price, saving, deadline, place count, testimonial and metric traces to a source or is removed.
Consent and segment note One line per send States the segment and its opt-in basis, or marks it not assessed.

Capability and Permission Boundaries

Read and search only; analysis is read-only. Publishing, spend, live account changes, outreach and personal-data processing need explicit, action-specific client authority. Sending or scheduling in Mailchimp or any email platform, and emailing anyone who has not opted in, is out of scope.

Degraded Mode

Without a confirmed email type, segment or opt-in basis, return the narrowest qualified result and mark the affected checks not assessed. Subject line options and a draft body for the most likely type can still be delivered, with assumptions flagged.

Decision Rules

Condition Action Failure or risk avoided
The email is a newsletter Give value first; use a reply or resource CTA, never a sales CTA unless the brand has built significant trust with this list. Readers who learn to ignore the newsletter.
Urgency, a deadline or scarcity is proposed Include it only if genuine and stated plainly ("Offer closes [date]", "Only [N] places remaining"); use a "Last chance" subject only if the list is genuinely being cleaned. False urgency and lost trust.
Subscribers have not opened or clicked in 60 or more days Send a reactivation email before any further promotion, with an explicit, guilt-free opt-out. Damaged sender reputation and spam reports.
A reactivation offer is being considered Use one only if relevant and authentic; never manufacture an offer purely to reactivate. A cynical offer that damages trust.
Social proof is needed Use one specific, traceable customer result, testimonial or metric. Vague claims ("our clients love us") or invented numbers.
The offer is premium or high-ticket Show proof, value and risk reduction with one appropriately weighted CTA; apply premium-commercial-writing. Discount-led copy that cheapens the offer.

Quality Standards

  • Subject line options are genuinely different in approach, not three versions of the same formula; the preheader complements the subject line without repeating it.
  • The opening earns attention before requesting or selling anything; no "we are pleased to announce" or "I hope this email finds you well" opener.
  • One clear CTA throughout; no competing actions in the same email.
  • British English throughout (organisation, colour, recognise, programme); no banned vocabulary in any section.
  • Scannable on mobile: short paragraphs, no walls of text, white space between sections.
  • Tone matches the brand voice and suits the EA professional register: warm but not unprofessional.
  • Premium or high-ticket emails show proof, value, risk reduction and one appropriately weighted CTA.
  • Passes the anti-ai-slop ship gate; a blocking factual, cultural, safety or permission defect stops release.

Anti-Patterns

  • Opening a promotional email with the product ("We are excited to offer you…"). Fix: open with the reader's desire or problem and lead with the benefit.
  • Two competing CTAs in one email. Fix: keep one action; move the second to a later email.
  • Addressing "dear subscribers" or "hello everyone". Fix: write to one person.
  • Sending further promotions to inactive subscribers. Fix: run reactivation first and let them leave cleanly.
  • Adding a price, result, quotation or metric without a traceable source. Fix: verify it or qualify/remove it.
  • Sending or scheduling from drafting authority alone, or emailing people who have not opted in. Fix: obtain explicit action-specific authority and confirm consent.
