Four Skills a lifecycle marketer should actually build, what goes in each, a worked SKILL.md, and the refuse conditions that keep a flow honest.
Email is the discipline where Claude Skills pay back fastest, because email is the most repetitive writing job in marketing. Same welcome flow, same cart-abandon logic, same subject-line guessing, week after week. Most marketers re-explain all of it to Claude every single session: here is the brand, here is the offer, here is the segment, do not invent a fake deadline. That re-explaining is the tax a Skill removes.
If you have not read the complete guide to Claude Skills for marketing, start there for what a Skill is and where it lives. This post is the email-specific version: which Skills earn their slot in a lifecycle marketer's setup, and what to write inside each one.
Build narrow, not broad. One Skill called "Email" that drafts sequences, picks segments, and writes subject lines will load on every conversation and produce mush. Four small Skills, each with a sharp trigger, beat it every time. Each Skill below names what it activates on, what it knows, and what it refuses to do.
The workhorse. This Skill activates when you ask Claude to draft or revise a multi-email flow: welcome, onboarding, post-purchase, win-back, abandoned cart, renewal. What makes it a Skill and not a prompt is that the structure of a good sequence is always true. Email one earns the open. Email two carries the single core message. Later emails add proof, handle one objection each, and the final email has a real reason to be the last.
What it knows: your standard flow templates (how many emails, what each one is for, the gap between sends), and a pointer to the offer file so it never guesses the price or the terms. What it refuses: inventing send timing you did not set, padding a three-email flow to seven to look thorough, and writing a PS line with a discount that nobody approved.
This one is narrow on purpose. It triggers when you ask for subject lines or preview text, and it does one job: produce a spread of genuinely different angles, not five rewordings of the same sentence. Curiosity, benefit-led, plain-and-literal, question, news. It labels each variant with its angle so you can pick by strategy, not vibe.
What it knows: your character limits, the words your audience has tuned out, and the offer context so the literal variant is actually accurate. What it refuses: fake urgency ("last chance" when it is not), false scarcity ("only 3 left" with no inventory logic behind it), and clickbait that the email body cannot pay off. A subject line that oversells the body is the fastest way to train an audience to ignore you.
The least obvious one, and the one that separates an email marketer from a copywriter. This Skill activates when you are deciding who a send goes to, not what it says. It knows your actual segments (engaged, lapsed, never-purchased, high-value, the named lifecycle stages) and the logic for each. Ask it to plan a re-engagement push and it reasons in terms of your real segments and suppression rules instead of generic "active vs inactive" filler.
What it knows: your segment definitions, your suppression and frequency-cap rules, and which segments are off-limits for promotional sends. What it refuses: recommending a blast to the whole list, ignoring a recent-send suppression, and treating a small high-intent segment as too small to bother with. It also refuses to invent segment sizes or open rates it cannot see.
Voice drift is worse in email than anywhere, because a flow is many drafts written across many sessions. Email one sounds like you. By email four, three sessions later, it sounds like a different company. This Skill loads your voice guide and holds the register steady across every email in a sequence, so the welcome and the win-back read like the same brand.
What it knows: your voice guide (the one you extracted with the free Voice and Tone Extractor), and the small set of email-specific moves: how you greet, how you sign off, how casual the PS gets. What it refuses: drifting more formal as the flow goes on, switching to corporate register for the "serious" renewal email, and using off-brand words you have explicitly banned.
Here is the smallest version of the sequence-drafting Skill that does real work. The same shape applies to the other three: YAML description that names the trigger, then knows / does / refuses.
--- name: email-sequence-drafter description: Use this Skill whenever the user is drafting or revising a multi-email lifecycle flow (welcome, onboarding, post-purchase, win-back, abandoned cart, renewal). Triggers on "sequence," "flow," "drip," "welcome series," "nurture," "win-back," "draft the emails." Loads the offer file and the standard flow templates before writing anything. --- # Email Sequence Drafter ## What this Skill knows The standard flow templates are in flows.md (this folder). The current offer, price, and terms are in offer.md. Read offer.md before writing any email. Never guess the price. Structure every flow on these rules: 1. Email 1 earns the open. One job: get read, not sell. 2. Each email carries ONE core message. No stacking. 3. Each later email handles one objection or adds one proof. 4. The final email has a real reason to be last. ## What this Skill does - Draft the full flow using the send timing in flows.md - Map each email to its single job before writing copy - Flag any email that is doing two jobs at once - Leave merge fields as {{FIRST_NAME}} style placeholders ## What this Skill refuses - Do not invent send timing the user did not set - Do not invent a deadline, discount, or scarcity claim. If the offer needs urgency, it is in offer.md or it does not exist. - Do not fabricate testimonials, review counts, or "join 10,000 marketers" social proof. Use only proof in offer.md. - Do not pad a short flow to look thorough. Three good emails beat seven filler ones. - If the user asks for a claim not backed by offer.md, ask for the source before writing it.
The refuse block is the part most email Skills skip, and it is the part that matters most. Email is where fabricated urgency and invented social proof do real damage: deliverability, unsubscribes, and the slow erosion of a list that learns to distrust you. A Skill that refuses to write "only 3 spots left" unless the offer file says so is a Skill that protects the asset. Hard-coding the refusal once means you stop relying on remembering it at 5pm on a send day.
Every one of these Skills points at a file: the offer file, the flow templates, the segment definitions, the voice guide. The Skill is plumbing. Those files are the work. A sequence drafter pointed at a vague offer file will write vague emails. A segmentation Skill that does not know your real segments will invent plausible nonsense.
So build the reference files first, then wrap them. If you want the full mechanics of writing the SKILL.md itself, the YAML, the install, the folder structure, the 20-minute build walkthrough covers it step by step. Start with the voice guide, because every one of the four Skills above leans on it.
The four free Claude Skills on the Hub are the same four free prompts packaged as installable Skills, with the YAML and instructions already wired. The Voice Extractor is the one most email marketers reach for first, because it produces the voice guide the brand-voice-across-the-flow Skill points at. CC BY 4.0, drag-and-drop, no email gate.
