Purpose

Generate a post-purchase email sequence (3-5 emails) that ascends customers from their initial purchase to a higher-ticket complementary offer. These emails deploy after the buyer has already said yes — trust is established, the product is in hand (or arriving), and the window for ascension is open. Each email must deliver genuine value before bridging to the upsell. The sequence arc moves from gratitude through value delivery to the offer, with urgency closing the window. Every email uses RMBC principles compressed into short-form format.

Inputs

Input	Required	Description
initial_product	Yes	What the customer already purchased — name, price, core promise
upsell_product	Yes	The higher-ticket offer — name, price, what it does, how it complements the initial purchase
upsell_price	Yes	Price of the upsell with any discount framing
target_audience	Yes	Who the buyer is — demographics, pain points, desires, sophistication level
sequence_length	No	Number of emails: 3, 4, or 5 (default: 5)
key_mechanism	No	The upsell product's unique mechanism (output from /mechanism-ideation)
send_timing	No	Days between emails (default: Day 1, 3, 5, 7, 9)

Execution Protocol

Step 1 — Load Framework Context

Read rmbc-context/SKILL.md to load RMBC framework definitions. Upsell sequences deploy RMBC across multiple touchpoints — Research informs the value content, Mechanism justifies the upsell, Brief structures the sequence arc, Copy executes each email.

Step 2 — Define the Sequence Arc

Map the emotional journey across the sequence:

Email	Role	Emotional State	RMBC Focus
1 — Thank You	Validate purchase, deliver quick win	Excited, hopeful	Research (reinforce their decision)
2 — Value Delivery	Teach something useful related to their purchase	Engaged, learning	Research → Mechanism tease
3 — Bridge	Connect initial product's limitation to upsell need	Curious, aware of gap	Mechanism reveal
4 — Offer	Present the upsell with full value stack	Desire, trust	Brief → Copy (full pitch)
5 — Urgency Close	Final window, scarcity, guarantee restatement	Fear of missing out	Copy (close)

For 3-email sequences: combine emails 1+2, 3+4, and keep 5. For 4-email sequences: combine emails 1+2 and keep 3, 4, 5.

Step 3 — Write Each Email

For each email, produce:

• Subject line (under 50 characters, mobile-optimized)
• Preview text (40-90 characters, complements subject)
• Body copy following the email's role from the arc
• CTA appropriate to the email's position (soft early, hard late)

Rules per email position:

• Emails 1-2: No selling. Pure value delivery. Build goodwill.
• Email 3: Bridge only. Reveal the gap, tease the solution. Soft CTA at most.
• Email 4: Full offer with mechanism, value stack, price anchoring, guarantee.
• Email 5: Urgency, deadline, guarantee restatement, final CTA. Short and direct.

Step 4 — Validate Sequence Coherence

Read all emails in order. Check:

1. Does each email build on the previous? No redundant points.
2. Does the value-to-pitch ratio feel earned? (At least 2 value emails before the offer)
3. Does the urgency in the final email feel real? (Deadline, limited quantity, or price increase)
4. Could a reader skip to email 4 and still understand the offer? (It must standalone too)

Output Format

## Upsell Sequence: [Initial Product] → [Upsell Product]

**Sequence Length:** [3-5] emails
**Send Schedule:** [Day 1, Day 3, Day 5, ...]
**Audience:** [target audience summary]

---

### Email 1: [Role Label] — Day [X]

**Subject:** [subject line]
**Preview:** [preview text]

[Full email body]

[CTA or sign-off appropriate to position]

---

### Email 2: [Role Label] — Day [X]

[...continue for each email...]

---

## Sequence Strategy Notes

- **Value-to-pitch ratio:** [X value emails : Y pitch emails]
- **Mechanism reveal timing:** Email [X] — [why this timing]
- **Urgency type:** [deadline | limited quantity | price increase | bonus expiration]
- **Standalone test:** Email [4] works as a standalone pitch: [yes/no + why]

Quality Criteria

• First 1-2 emails must deliver genuine value — no selling, no "by the way" pitches

• Each email must have a clear single purpose aligned to its arc position

• Subject lines must be under 50 characters and work on mobile

• The bridge email (3) must make the upsell feel like a logical next step, not a random offer

• Offer email (4) must work as a standalone pitch if read in isolation

• Urgency in final email must be real — name the specific deadline, quantity, or trigger

• Sequence must feel like a relationship, not a drip campaign of pitches

• Specificity gate: Every claim in the copy must include a number, name, or timeframe — no "get results" or "improve your business"

• Mechanism quantification: When referencing the mechanism, include at least one specific data point (number, timeframe, study reference)

• Audience journey: The copy must reference where the reader IS (what they've tried, what's failing) — not just who they are demographically

• Proof diversity: Use at least 2 different proof types (testimonial, statistical, authority, case study) — do not rely on a single proof mode

• Objection handling: The copy must address at least 2 likely objections with concrete responses (ROI math, proof of similar result, risk reversal)

Related Skills

• Run /mechanism-ideation for the upsell product's mechanism
• Run /upsell-script for the immediate post-purchase OTO page (before this sequence)
• Run /email-promo for standalone promotional emails outside a sequence
• Run /hook-battery for subject line inspiration
• Validate with /rmbc-copy-audit
