Email Voice

Klaviyo & Mailchimp prompts that sound like a real person.

Email is where the relationship lives. These prompts get Claude to write flows that read like a founder writing to a customer, not a brand to a list. Built for Klaviyo flows, abandoned cart sequences, welcome series, win-back, and the boring-but-critical transactional voice.

Welcome series (5 emails)

2 prompts

Welcome series brief

Claude
Write a 5-email Klaviyo welcome series for [BRAND], a [CATEGORY] brand. Voice: founder writing personally, calm, no hype, no emoji. Email 1: thank you + the one thing we want them to know about us. Email 2: founder origin story in 4 short paragraphs. Email 3: how to pick your first product, no upsell pressure. Email 4: one happy customer story, quoted. Email 5: low-key first-purchase incentive with a single deadline. Output subject + preview + body. Each body under 220 words.

Welcome email subject lines

Claude
Write 20 subject lines for the first email of a [BRAND] welcome series. 10 plain-curiosity, 10 founder-voice. No emoji. Each under 45 characters. Lead with specificity, not hype. Output numbered.

Abandoned cart flow

2 prompts

3-email cart flow

Claude
Write a 3-email Klaviyo abandoned cart flow for [BRAND]. Email 1 (1 hour): friendly reminder, 'your [ITEM] is waiting', lead with the actual product, 1 line on the most common hesitation answered. Email 2 (24 hours): one happy customer review of that product. Email 3 (72 hours): single soft incentive with a clear expiry. Voice: helpful, never pressured. Subject + preview + body. Each under 140 words.

Subject line variations

Claude
Write 10 abandoned cart subject lines for [BRAND] for a customer who left [PRODUCT NAME] in their cart. Mix question, statement, founder-voice. No emoji. Lead with the product, not 'you forgot something'. Each under 45 characters.

Win-back & re-engagement

2 prompts

60-day lapse, 2 emails

Claude
Write a 2-email win-back flow for a customer who hasn't ordered in 60 days from [BRAND]. Email 1: no incentive, just an honest check-in with a 1-line ask 'is the product still working for you'. Email 2 (5 days later): one specific offer they haven't seen before. Voice: founder writing personally. Each under 160 words. Subject + preview + body.

Lapsed subscriber re-opt

Claude
Write a single re-opt-in email for [BRAND] subscribers who haven't opened anything in 90 days. The honest goal: confirm they still want to hear from us, with a clear single-click way to stay. Voice: candid, light, never desperate. Under 110 words.

Campaign emails

3 prompts

Launch announcement, founder voice

Claude
Write a single launch announcement email for [PRODUCT NAME] from [BRAND]. Voice: founder, personal, calm. Structure: (1) the problem we kept hearing about, (2) what we made, (3) what it does that nothing else does, (4) how to get one. Subject + preview + body under 220 words. No exclamation marks. No emoji.

Last-call email

Claude
Write a final last-call email for a [BRAND] promotion ending tonight. Subject + preview + body under 90 words. One specific deadline, one specific reason to act, one direct CTA. Voice: calm, useful, never frantic.

Restock notification

Claude
Write a restock notification email for [PRODUCT NAME] from [BRAND]. Mention this is the [Nth] time it sold out. Acknowledge the wait. Under 90 words. Subject + preview + body.

Transactional voice

2 prompts

Order confirmation rewrite

Claude
Rewrite the order confirmation email for [BRAND] in our voice (calm, brief, slightly warm, never corporate). Keep the legally required pieces (order number, items, total, shipping address, return window). Add one short note from the founder about what to expect next. Under 130 words.

Shipping delay apology

Claude
Write a shipping delay apology email for [BRAND] for orders affected by [REASON]. Be honest about the cause, give a real new ETA, offer one tangible make-good. Under 110 words. No corporate-speak. No 'we apologize for any inconvenience'.
