Clarify First

Before generating the email, confirm these inputs. If any is unknown or vague, ASK — do not assume:

• ICP / prospect context — job title, company type/size, seniority (drives the opener, relevance, and voice calibration)
• Specific problem + outreach trigger — the pain and why now (selects the framework and shapes the opener)
• The one proof point — a specific number, named customer, or result (drives the credibility line)
• The single CTA / goal — book a call, get a reply, or get a referral (drives the one ask)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.

Quick Start

Write a First-Touch Email

1. Define the ICP, specific problem, and outreach trigger
2. Select voice calibration based on recipient seniority
3. Write opener about their world (not yours)
4. State relevance in 1-2 sentences with specific proof
5. Close with a single, low-friction ask
6. Generate 3 subject line variants
7. Validate: under 150 words, no corporate speak, one CTA

Build a Full Sequence

1. Write the first email (above)
2. Plan 4-5 follow-ups, each with a different angle
3. Set escalating gap cadence (Day 1, 4, 9, 16, 25, 35)
4. Write each follow-up as a standalone (recipient does not remember earlier emails)
5. End with a breakup email that closes the loop professionally
6. Validate deliverability setup before sending

Core Workflows

Workflow 1: Single First-Touch Email

Step 1: Gather Context

Required information:

• Sender context: Role, company, what they sell, key proof points
• Prospect context: Job title, company type/size, likely problem, trigger for outreach
• Goal: Book a call? Get a reply? Get a referral?

Step 2: Choose Framework

Step 3: Draft the Email

Structure:

Subject: [2-4 words, looks like an internal email]

[Opener: 1 sentence about their world — trigger, observation, or question]

[Relevance: 1-2 sentences connecting their situation to what you do]

[Proof: 1 sentence of credible evidence — specific number, named customer, result]

[Ask: 1 sentence with a single, specific, low-friction CTA]

[Sign-off]

Step 4: Validate

• Under 150 words total
• Opener is about them, not you
• No sentence starts with "I" or "We"
• One CTA, not multiple
• CTA is a question, not a statement
• No jargon or corporate speak
• Would a friend send this to another friend in business?

Workflow 2: Full Sequence Build

Step 1: Write Email 1 (Using Workflow 1)

Step 2: Plan Follow-Up Angles

Each follow-up needs a distinct angle. Plan before writing:

Step 3: Write Each Follow-Up

Rules for every follow-up:

• Standalone: does not require reading previous emails
• New angle: brings something the previous email did not
• Shorter than Email 1 (each subsequent email gets shorter)
• Never says "just checking in" or "circling back"
• Never references all previous emails ("As I mentioned in my last three emails...")

Step 4: Write the Breakup Email

The breakup email closes the loop. It signals this is the last one, which paradoxically increases reply rate.

Template:

Subject: closing the loop

[Name],

Last note from me. If [specific problem] becomes a priority,
reply here and I'll pick it up.

If there's someone else at [Company] better suited for this
conversation, a name would help.

Either way — [genuine well-wish related to something specific].

[Sign-off]

Workflow 3: Performance Iteration

Step 1: Diagnose the Problem

Step 2: Rewrite the Underperforming Element

Focus on one element at a time. Do not rewrite the entire email when only the subject line is the problem.

Step 3: Test and Measure

• A/B test subject lines with minimum 100 sends per variant
• Test one variable at a time
• Wait for 3-5 days of data before drawing conclusions
• Document every test and result for future reference

Writing Principles

1. Write Like a Peer, Not a Vendor

The moment your email sounds like marketing copy, it is deleted.

Test: Would you send this to a smart colleague at another company? If not, rewrite.

2. Every Sentence Earns Its Place

Each sentence must do one of these jobs:

• Create curiosity
• Establish relevance
• Build credibility
• Drive to the ask

If a sentence does none of these, cut it.

3. Personalization Must Connect to the Problem

Generic personalization is worse than none.

• Bad: "I saw you went to Stanford" followed by a pitch unrelated to Stanford
• Good: "I saw you're hiring three SDRs — usually a signal that you're scaling cold outreach. That's exactly the challenge we help with."

The personalization must bridge to the reason for reaching out.

4. Lead with Their World, Not Yours

The opener should be about their situation, problem, or context. Not about you or your product.

5. One Ask Per Email

Do not ask them to book a call, watch a demo, read a case study, AND reply with their timeline. Pick one.

Voice Calibration by Audience

Rule: The higher up the org chart, the shorter your email needs to be.

Subject Line Framework

Principles

The goal of a subject line is to get the email opened. Not to convey value, not to be clever. Just opened.

The best cold email subject lines look like internal emails: short, slightly vague, enough curiosity to click.

Patterns That Work

Patterns That Kill Opens

• ALL CAPS anything
• Emojis in subject lines
• Fake Re: or Fwd: (damages trust before the first word)
• Question format ("Are you struggling with X?") — sounds like an ad
• Company name mention ("Acme Corp: helping you achieve...")
• Blog headline format ("5 ways to improve your...")
• Exclamation marks

Follow-Up Strategy

Cadence

Gaps increase over time. Persistent but not annoying.

Follow-Up Angle Rotation

Personalization Framework

Three Tiers of Personalization

Tier 1: Segment-Level (Minimum)

• Industry-specific pain points
• Company size-specific challenges
• Role-specific language and priorities

Tier 2: Company-Level (Standard)

• Recent company news (funding, hiring, product launch)
• Tech stack signals (what tools they use)
• Growth signals (job postings, office expansion)

Tier 3: Individual-Level (Premium)

• Content they have published (posts, articles, talks)
• Career moves (new role, promotion)
• Shared connections or experiences
• Specific project or initiative they are leading
