Project Overview
Project
beginner15 minAI Email Sequence Generator
Email marketing still delivers the highest ROI of any digital channel — roughly $36 for every $1 spent. The challenge is writing sequences that feel personal at scale. In this project you will build a reusable prompt workflow that takes a product description and target audience, then outputs a polished multi-email sequence ready for your ESP.
Phase 1: Audience Analysis
Before writing a single word of copy, you need a crystal-clear picture of who you are writing to. A vague audience brief produces vague emails. The prompt below forces the AI to output a structured persona document you can reference in every later step.
Audience Persona Builder
Generates a structured buyer persona to anchor every email in the sequence.
You are an expert email marketing strategist.
Product: {{product_name}} — {{one_line_description}}
Price point: {{price}}
Primary audience hint: {{audience_hint}}
Create a detailed buyer persona for the ideal subscriber who would purchase this product via an email sequence. Include:
1. Demographics (age range, job title, income bracket)
2. Psychographics (goals, fears, daily frustrations)
3. Awareness stage (Problem-Aware, Solution-Aware, or Product-Aware — pick the most likely and explain why)
4. Preferred email reading habits (mobile vs. desktop, time of day, scan vs. deep-read)
5. Three emotional triggers that would make them click "Buy Now"
Format the output as a clean markdown document with headers for each section.Phase 2: Subject Line Generation
Subject lines determine open rates, and open rates determine everything else. The goal is volume first, curation second: generate many options, then filter by proven psychological frameworks.
Subject Line Brainstorm
Produces 20 subject lines across 5 emails, organized by psychological framework.
Using the buyer persona below, generate 20 email subject lines for a 5-email product launch sequence for {{product_name}}.
--- PERSONA ---
{{paste_persona_output}}
--- END PERSONA ---
For each email in the sequence, provide 4 subject line options using these frameworks:
• Email 1 (Curiosity hook) — tease the problem without revealing the solution
• Email 2 (Social proof) — reference results, numbers, or testimonials
• Email 3 (Pain agitation) — make the cost of inaction feel urgent
• Email 4 (Objection buster) — preemptively address the #1 buying objection
• Email 5 (Deadline/scarcity) — create genuine urgency
Rules:
- Keep every subject line under 50 characters
- Use no more than one emoji per line
- Avoid spam trigger words (free, act now, limited time)
Output as a numbered table: Email # | Framework | Subject Line | Character Count- Curiosity gaps increase open rates by 10-22% compared to straightforward subject lines.
- Numbers in subject lines (e.g., "3 mistakes...") boost opens by roughly 15%.
- Personalization tokens like {{first_name}} lift open rates but only when the rest of the line is strong.
Phase 3: Email Body Copy
Now you turn subject lines into full email drafts. The key constraint: each email should have a single call-to-action. Multiple CTAs dilute click-through rates. The prompt below enforces this and includes a specific copywriting structure.
Email Body Copy Writer
Generates a single email body following a proven direct-response structure.

--- PERSONA ---
{{paste_persona_output}}
--- END PERSONA ---
Write Email {{email_number}} of 5 for {{product_name}}.
Subject line: {{chosen_subject_line}}
Goal of this email: {{email_goal}}
Single CTA: {{cta_text}} → {{cta_url}}
Structure the email as follows:
1. **Hook** (1-2 sentences) — open with a relatable story, question, or surprising fact
2. **Problem** (2-3 sentences) — agitate the specific pain the persona feels
3. **Bridge** (2-3 sentences) — introduce the product as the natural solution
4. **Proof** (1-2 sentences) — one concrete result, stat, or testimonial
5. **CTA** (1 sentence) — clear, single action with the link
6. **P.S. line** — reinforce urgency or add a bonus
Tone: conversational, confident, zero fluff. Reading level: 6th grade. Target length: 150-250 words.
Output the email in plain text ready to paste into an ESP. Use line breaks for readability — no HTML.Phase 4: A/B Variant Testing
Every professional sequence should include at least one A/B test. The most impactful element to test is the opening hook — it determines whether readers keep scrolling or archive. The prompt below creates a controlled variant that changes only the hook while keeping everything else identical.
A/B Variant Generator
Creates a controlled A/B variant by changing a single element for clean test results.
Here is the original version of Email {{email_number}}:
--- ORIGINAL ---
{{paste_email_body}}
--- END ORIGINAL ---
Create an A/B variant (Version B) that changes ONLY the following element: {{element_to_test}}.
Keep every other part of the email identical — same CTA, same proof point, same P.S. line.
Explain in one sentence why the variant might outperform the original, citing a specific copywriting principle.
Output:
1. Version B (full email text)
2. Hypothesis statement
3. Recommended sample size for statistical significance (assume a 20% baseline open rate)Phase 5: Automated Follow-Ups
Not everyone opens every email. A well-designed sequence includes conditional follow-ups for non-openers and non-clickers. This final prompt generates re-engagement messages that reference the original without repeating it.
Follow-Up Sequence for Non-Openers
Generates a complete follow-up layer for non-openers plus a graceful break-up email.
I need follow-up emails for subscribers who did NOT open the emails in my launch sequence for {{product_name}}.
Original subject lines:
1. {{subject_1}}
2. {{subject_2}}
3. {{subject_3}}
4. {{subject_4}}
5. {{subject_5}}
For each original email, write a short follow-up (80-120 words) that:
- Uses a completely different subject line angle
- Opens with a new hook (do not repeat the original)
- Summarizes the core value proposition in one sentence
- Ends with the same CTA link
Also write one final "break-up" email (Email 6) for subscribers who did not open any of the five follow-ups. The break-up email should be empathetic, give them an easy opt-out, and leave the door open.
Output all six follow-up emails in order, each with Subject Line and Body.Putting It All Together
- Run the Audience Persona Builder and save the output.
- Generate subject lines using the persona as context.
- Pick the best subject line per email and generate body copy for all five.
- Create A/B variants for at least Email 1 and Email 3.
- Generate follow-up emails for non-openers.
- Review the full sequence for consistent tone, correct CTAs, and a logical narrative arc.
