I used to pay a freelance copywriter $200 per email. Welcome sequences, cart abandonment flows, product launches — every email was a line item. Then I started testing AI prompts against her drafts.
The AI won 5 out of 7 A/B tests.
I didn't fire the copywriter — I just stopped needing her for first drafts. These seven prompts now handle the heavy lifting across every email type I send. Each one includes the exact prompt, what tool or service it replaces, and a one-line explanation of why it actually works.
1. Welcome Email Sequence — Replaces ConvertKit Templates ($29/month)
Most welcome sequences are three emails of "thanks for signing up" fluff. Subscribers decide in the first 48 hours whether they'll ever open your emails again. This prompt builds a sequence that earns that habit.
"Write a 5-email welcome sequence for [product/brand]. Subscriber signed up for [lead magnet/offer]. Email 1 (immediate): Deliver the promised resource + one surprising insight they didn't expect. Email 2 (Day 1): Share the #1 mistake people in [audience] make — and how [product] avoids it. Email 3 (Day 3): Tell a specific customer story: problem → discovery → measurable result. Email 4 (Day 5): Address the biggest objection to [product] head-on. End with a soft CTA. Email 5 (Day 7): Direct pitch with urgency. Include a specific deadline or limited offer. Tone: [conversational/authoritative/casual]. Each email: subject line (under 40 chars) + preview text (under 90 chars) + body (150-250 words). No fluff sentences — every line should earn the next line."
What it replaces: ConvertKit email templates, hiring a copywriter for onboarding flows ($500-$1,500 per sequence)
Why it works: Forces a narrative arc across all five emails instead of treating each one as a standalone blast — which is why most welcome sequences lose 60% of opens by email 3.
2. Cart Abandonment Email — Replaces Klaviyo Smart Sends ($45/month)
Cart abandonment emails recover 5-15% of lost revenue — but only if they don't read like a robot wrote them. Most templates are "You forgot something!" followed by a product image. That's not persuasion, that's a notification.
"Write a 3-email cart abandonment sequence for [product] at [price point]. Email 1 (1 hour after): Casual, no pressure. Acknowledge they were browsing. Include one specific benefit they'd miss. Subject line should NOT mention 'cart' or 'forgot.' Email 2 (24 hours): Address the most likely objection for [price point] products — [too expensive / not sure it works / need to think about it]. Include one proof point (testimonial, stat, or guarantee). Email 3 (48 hours): Final email. Create genuine urgency — either stock-based, time-based, or social proof-based. Make the CTA impossible to misunderstand. Each email: subject line + preview text + body (100-200 words). Tone: like a helpful friend, not a pushy salesperson."
What it replaces: Klaviyo's smart send templates, Abandoned Cart Recovery apps ($20-$50/month)
Why it works: Structures escalation — casual → logical → urgent — instead of hitting the same note three times, which trains subscribers to ignore you.
3. Newsletter Subject Line A/B Tests — Replaces SubjectLine.com ($49/month)
Your subject line determines whether 20% or 45% of your list reads your email. Most people write one subject line, call it done, and wonder why open rates are flat. This prompt gives you a full test matrix in 30 seconds.
"Generate 20 email subject lines for my [newsletter type] about [this week's topic]. Organize into 4 test groups of 5: - Group A: Curiosity gap (open a loop that the email closes) - Group B: Specific number or data point - Group C: Direct benefit statement - Group D: Contrarian or unexpected angle Constraints: Each under 40 characters. No spam trigger words (free, guaranteed, act now). No ALL CAPS. No excessive punctuation. Each should work on mobile (front-load the hook in first 25 chars). For each group, mark your top pick and explain in one sentence why it should win the A/B test."
What it replaces: SubjectLine.com scoring tool, CoSchedule Headline Analyzer, manually brainstorming for 30 minutes
Why it works: Pre-groups by psychological trigger so you're A/B testing actual strategies — not just random word swaps.
4. Re-engagement (Win-Back) Email — Replaces Mailchimp Automations ($30/month)
Someone hasn't opened your last 10 emails. They're not dead — they're bored. Most win-back emails beg: "We miss you!" That's needy. This prompt takes a different approach.
"Write a 3-email win-back sequence for subscribers who haven't opened in 90+ days. Product: [product]. Email 1: Lead with something genuinely new or changed since they last engaged. No guilt-tripping. Subject line should spark curiosity about what they missed — not remind them they've been absent. Email 2 (3 days later): Share your single best-performing piece of content or biggest customer win from the last 90 days. Make it so good they'd forward it. Email 3 (7 days later): Honest breakup email. Tell them you're removing inactive subscribers in 48 hours. Give them a one-click 'stay' option. No fake urgency — actually remove them if they don't click. Tone: confident, not desperate. Each email under 150 words. Subject lines under 35 characters."
What it replaces: Mailchimp re-engagement automations, ActiveCampaign win-back workflows ($30-$80/month)
Why it works: The breakup email (Email 3) consistently gets 2-3x the open rate of the re-engagement emails — because loss aversion beats persuasion every time.
5. Product Launch Announcement — Replaces Copywriter Retainer ($500+/launch)
Launch emails are where most brands fumble. They either write a feature list nobody cares about or go so heavy on hype that it feels like a late-night infomercial. The sweet spot is specific + excited.
"Write a product launch email for [product name] launching on [date] at [price]. Structure: - Opening line: One sentence that names the specific problem this product kills. No buildup. - What it is: 2-3 sentences. What does the buyer actually get? Be specific — files, access, templates, features. - Why now: What changed that makes this the right time? (New technology, customer feedback, market gap.) - Social proof: One specific result from a beta user, early tester, or your own usage. Include a number. - The offer: Price, what's included, any launch bonus or deadline. - CTA: One clear action. No 'learn more' — tell them exactly what happens when they click. Tone: excited but grounded. Like telling a friend about something you built that actually works. Under 300 words total."
What it replaces: Hiring a launch copywriter ($500-$2,000 per launch), Product launch email templates
Why it works: Forces the "why now" section — which is the part most launch emails skip and exactly the part that converts fence-sitters.
6. Cold Outreach Personalization — Replaces Lemlist Templates ($59/month)
Cold email is dead — bad cold email is dead. Personalized cold email still gets 15-25% reply rates. The difference is whether you sound like you actually looked at the recipient's work or just scraped their name from a list.
"Write a cold outreach email to [name], [title] at [company]. Context about them: [paste their recent LinkedIn post / tweet / podcast quote / product update — 2-3 sentences]. My product: [one sentence about what I sell]. Rules: - First line must reference something specific they said or did (not their company, not their job title) - Do NOT compliment them generically ('I love your work'). Reference a specific opinion they expressed. - Connection to my product must feel natural, not forced. If there's no natural bridge, say so. - The ask: one specific, low-commitment action (reply, 15-min call, watch a 2-min demo) - Total length: 4-6 sentences. No 'I hope this email finds you well.'"
What it replaces: Lemlist personalization tokens, Smartwriter AI ($59/month), hiring a VA to research prospects ($15-$25/hour)
Why it works: Forces genuine personalization by requiring a specific reference — most cold email tools just insert {{first_name}} and call it personalized.
7. Weekly Digest Summary — Replaces Curated.co ($79/month)
If you send a weekly newsletter, you know the pain: 2 hours every week summarizing links, writing intros, and trying to make a digest feel like it was written by a human. This prompt cuts that to 15 minutes.
"Write a weekly email digest for [newsletter name] covering [topic/industry]. Here are this week's 5-7 items to include: [Paste headlines + one-sentence context for each item] For each item, write: - A 1-sentence summary that tells the reader why they should care (not what happened — why it matters to them) - A take or opinion in 1 sentence (agree, disagree, or add context the original didn't mention) Opening paragraph: 2-3 sentences setting the theme for this week. What's the thread connecting these items? Closing: A question or prediction that invites replies. Tone: [knowledgeable insider / curious explorer / opinionated analyst]. Total length: 400-600 words."
What it replaces: Curated.co ($79/month), Mailbrew, spending 2+ hours manually writing your digest every week
Why it works: Adds editorial perspective to each item — which is what separates a newsletter people forward from a link dump they archive.
