Quick Start

Write a First-Touch Email

• Define the ICP, specific problem, and outreach trigger

• Select voice calibration based on recipient seniority

• Write opener about their world (not yours)

• State relevance in 1-2 sentences with specific proof

• Close with a single, low-friction ask

• Generate 3 subject line variants

• Validate: under 150 words, no corporate speak, one CTA

Build a Full Sequence

• Write the first email (above)

• Plan 4-5 follow-ups, each with a different angle

• Set escalating gap cadence (Day 1, 4, 9, 16, 25, 35)

• Write each follow-up as a standalone (recipient does not remember earlier emails)

• End with a breakup email that closes the loop professionally

• 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

Framework Best When Structure

Problem-First Prospect has a visible pain point Problem observation > Relevance > Ask

Trigger-Based There is a specific event (funding, hiring, news) Trigger reference > Connection to problem > Ask

Mutual Connection Referral or shared network Name drop > Context > Ask

Value-First You have something genuinely useful to share Insight/resource > Brief context > Ask

Direct Ask Prospect is high-intent or very senior Brief context > Direct question

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:

Email Day Angle What is New

1 Day 1 Problem-first Initial outreach

2 Day 4 New evidence Case study, data point, or recent result

3 Day 9 Different pain point Alternative angle on their world

4 Day 16 Industry insight Something notable about their space

5 Day 25 Direct question Simple, clear ask without context

6 Day 35 Breakup Professional close, referral ask

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

Symptom Likely Cause Fix

Low open rate (< 25%) Subject lines Test new subject line patterns

Opens but no replies (< 2% reply rate) Email body Rewrite with stronger relevance and lower-friction CTA

Replies but wrong outcome CTA mismatch Adjust the ask

High bounce rate (> 5%) List quality Verify email addresses before sending

Landing in spam Deliverability Check SPF/DKIM/DMARC, reduce send volume, warm domain

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

Audience Length Tone Subject Style What Works

C-suite (CEO, CRO, CMO) 3-4 sentences Ultra-brief, peer-level, strategic Short, vague, internal-looking Big problem > relevant proof > one question

VP / Director 5-7 sentences Direct, metrics-conscious Slightly more specific Specific observation + clear business angle

Manager 7-10 sentences Practical, shows homework Can be descriptive Specific problem + practical value + easy CTA

Technical (Engineer, Architect) 7-10 sentences Precise, no fluff Technical specificity Exact problem > precise solution > low-friction ask

Founder / Solo 5-7 sentences Empathetic, peer-to-peer Casual, human Shared experience + relevant proof + conversational ask

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

Pattern Example Why It Works

Two or three words "quick question" Looks like a real email from a colleague

Specific trigger + question "your TechCrunch piece" Specific enough to not look like spam

Shared context "re: Series B" Feels like a follow-up, not cold

Observation "your ATS setup" Relevant, not salesy

Referral hook "[mutual name] suggested I reach out" Social proof front-loaded

Role-specific "SDR team scaling" Shows you know who they are

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

Email Send Day Gap Notes

Email 1 Day 1 — First touch

Email 2 Day 4 +3 days New evidence angle

Email 3 Day 9 +5 days Different pain point

Email 4 Day 16 +7 days Industry insight

Email 5 Day 25 +9 days Direct question

Breakup Day 35 +10 days Close the loop

Gaps increase over time. Persistent but not annoying.

Follow-Up Angle Rotation

Angle Type Description Example

New evidence Case study, data point, recent result "Since my last note, we helped [Company] reduce [metric] by [%]"

Different pain Alternative problem in their world "Setting aside [topic A] — are you dealing with [topic B]?"

Industry insight Something notable about their space "Saw [industry trend]. Most teams are responding by [approach]"

Direct question Simple ask without buildup "[Name], quick one: who handles [function] at [Company]?"

Reverse ask Request for referral "If this isn't your area, who would you point me to?"

Social proof Relevant peer doing it "[Similar company] just went through this — here's what worked"

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

Personalization Sources

Source What You Find How to Use

LinkedIn profile Role, tenure, content they share Role-specific opener, reference their posts

Company blog Priorities, culture, technology choices Connect your solution to their stated priorities

Job postings Growth areas, pain points, tech stack "You're hiring for X, which usually means..."

Press/news Funding, partnerships, launches Trigger-based openers

GitHub/tech blogs Technical decisions, stack choices Technical relevance and credibility

Podcast/talks Opinions, expertise areas "Your point about X in [talk] resonated..."

Deliverability Setup

Infrastructure Requirements

Component What Why

Dedicated sending domain mail.yourdomain.com or outreach.yourdomain.com Protects primary domain reputation

SPF record DNS TXT record authorizing sending servers Proves you are authorized to send

DKIM signing Cryptographic signature on emails Proves emails were not modified in transit

DMARC policy DNS record specifying SPF/DKIM enforcement Tells receiving servers how to handle failures

Domain warmup 4-6 weeks of gradually increasing volume Builds sender reputation with ISPs

Warmup Schedule

Week Daily Volume Notes

1 10-20 Send to engaged contacts only

2 20-40 Mix of warm and cold contacts

3 40-70 Begin cold outreach at low volume

4 70-100 Monitor bounce rates closely

5-6 100-150 Increase if bounce rate < 3%

7+ 150-200 max Steady state for cold outreach

Deliverability Monitoring

• Bounce rate: Keep under 3% (above 5% damages reputation)

• Spam complaint rate: Keep under 0.1%

• Verify email addresses before sending (use verification services)

• Monitor blacklists monthly (MXToolbox, Google Postmaster)

• Use mail-tester.com to check deliverability score before campaigns

Email Format Rules

• Plain text or minimal HTML (no logos, images, or heavy formatting)

• No tracking pixels if possible (they trigger spam filters)

• Limit links to 1-2 maximum

• Avoid spam trigger words: "free," "guarantee," "act now," "limited time"

• Keep emails under 200 words

• Include a physical address (CAN-SPAM requirement)

• Include an unsubscribe mechanism

Compliance Requirements

CAN-SPAM (United States)

Required for all commercial email to US recipients:

• Sender identity is clear and not misleading

• Subject line is not deceptive

• Physical postal address included

• Opt-out mechanism present and functional

• Opt-out requests honored within 10 business days

• Message identified as an advertisement (if applicable)

GDPR (European Union)

Required for email to EU/EEA residents:

• Legitimate interest basis documented for B2B outreach

• Prospect data collected from lawful sources

• Privacy notice accessible

• Data processing records maintained

• Right to erasure honored promptly

• Data minimization: only collect what you need

• No consent required for B2B if legitimate interest applies, but this must be documented and defensible

CASL (Canada)

Required for commercial electronic messages to Canadian recipients:

• Express or implied consent documented

• Sender identification clear

• Unsubscribe mechanism functional

• Implied consent valid for 2 years from last transaction or 6 months from inquiry

Best Practice Regardless of Jurisdiction

• Always include an easy unsubscribe option

• Honor opt-outs immediately (do not wait the legal maximum)

• Do not buy email lists (poor quality, compliance risk)

• Document your legal basis for outreach

• Keep records of consent and opt-out requests

Anti-Patterns

Pattern Why It Fails

"I hope this email finds you well" Instant signal that this is templated mass outreach

"I wanted to reach out because..." Three words of nothing before saying anything

Opening with "My name is X and I work at Y" They can see your name. Start with something useful.

Feature dump in email 1 Nobody cares about features when they do not trust you yet

HTML templates with logos and colors Looks like marketing, gets spam-filtered

Fake Re:/Fwd: subject lines Deceptive, destroys trust

"Just checking in" follow-ups Adds no value, removes credibility

Social proof without context "We work with 500 companies" means nothing without relevance

Long-form case study in email 1 Save it for follow-up

Passive CTAs ("Let me know if you're interested") Weak. Ask a direct question or propose a specific step.

Multiple CTAs in one email Creates decision paralysis. One ask per email.

Sending from your primary domain Risks your entire domain reputation

Best Practices

Send from a real person, not a company alias — "sarah@mail.acme.com" outperforms "sales@acme.com" every time.

Read the email aloud before sending — If you hear yourself droning, cut. If it sounds like a brochure, rewrite.

Time your sends — Tuesday through Thursday, 8-10 AM in the prospect's timezone, produces the highest open rates for B2B.

Verify emails before campaigns — A 5% bounce rate damages your domain reputation. Verify every address.

Track reply rate, not open rate — Open tracking is unreliable (privacy features block tracking pixels). Reply rate is the metric that matters.

Build sequences, not individual emails — Most replies come from follow-ups, not the first email. Plan the full sequence before writing.

Document your playbook — Every winning email, subject line, and angle should be documented for the team. Build institutional knowledge.

Respect opt-outs immediately — Not just legally required, but professionally essential. Process within 24 hours.

Rotate sending domains — Use 2-3 sending domains to distribute volume and protect reputation.

Segment relentlessly — A generic template sent to 1,000 people will underperform a personalized email sent to 50 who match your ideal profile.

Integration Points

• Copywriting — Use for landing page copy and marketing page copy. Cold email follows different constraints (shorter, personal tone, no visual design).

• Content Strategy — Use to create content assets (case studies, guides) referenced in follow-up emails.

• Marketing Context — Use for ICP definition and positioning. If you do not know who you are targeting and why, cold email is the wrong tool.

• Marketing Psychology — Apply psychological principles (reciprocity, social proof, scarcity) to strengthen email messaging.

• Campaign Analytics — Use to track sequence performance and optimize based on data.
