First-Touch

5 prompts

Personalized Cold Email

1/20

<role>Peer-to-peer B2B sales professional</role> <task>Write cold email to [prospect]</task> <research>[paste LinkedIn/site/recent post details]</research> <offer>[describe]</offer> <voice_samples>[paste your best past cold emails if available]</voice_samples> <output> - Specific subject line referencing research - Personalized opener (not generic) - One-line pain relevant to their role - Soft offer as help - Low-stakes CTA Max 120 words. Feel human, not templated.

Writes personalized cold emails with research-specific opener, pain framing, and soft CTA.

💡

Pro tip: Claude's voice matching from samples makes cold emails feel like one specific person wrote them, not a template. Paste your 3 best past emails and Claude matches tone precisely.

Subject Line A/B Set

2/20

<task>Generate 10 cold email subject lines</task> <offer>[describe]</offer> <output> Categories (2 each): short+curious, personalized, benefit, referral, soft/low-pressure. Each with preview text, predicted open rate, spam flag check.

Generates 10 subject line A/B variants across 5 categories with open-rate predictions.

💡

Pro tip: Short subject lines (3-5 words) often outperform clever ones. "Quick question" beats "Leveraging AI for sustainable growth." Test short vs creative.

Opener Line Generator

3/20

<task>Write 15 cold email opener lines</task> <prospect>[describe]</prospect> <research_sources>[LinkedIn, content, company news]</research_sources> <output> 15 openers referencing specific details that transition naturally to pitch. Rank by authenticity.

Generates 15 personalized openers sourced from research with authenticity ranking.

💡

Pro tip: Generic compliments ("love your content!") = skipped. Specific observations ("your post on X stuck with me because Y") = replied. Compliments need substance.

Value-First Email

4/20

<task>Write give-before-ask cold email</task> <value>[insight / audit / resource]</value> <future_offer>[describe — not pitched in this email]</future_offer> <output> - Subject hinting value - Direct opener on what I noticed - Give specific value - NO pitch this email - Polite close </output>

Writes value-first cold emails giving specific help without pitching.

💡

Pro tip: Give-before-ask converts 3-5× better. But the value must be real — "quick tip" without substance reads as cheap. Give something a stranger would pay for.

Short & Direct (50-80 words)

5/20

<task>Write extremely short cold email</task> <prospect>[describe]</prospect> <offer>[describe]</offer> <constraint>50-80 words total</constraint> <output> Specific subject → personalized opener → one-line pitch → one-sentence CTA. No bullet lists, no sig image.

Writes 50-80 word direct cold emails with peer-to-peer tone.

💡

Pro tip: Executives reply to short cold emails at 2-3× the rate of long ones. If it takes >30 seconds to read, it's too long.

Follow-Ups

5 prompts

4-Email Follow-Up Sequence

6/20

<task>Write 4-email follow-up to unreplied cold email</task> <original>[describe]</original> <timing>day 3, 7, 14, 21</timing> <output> Each email: new angle, shorter than last, no "just following up", specific subject, single CTA. Email 4 = graceful breakup.

Writes 4-email follow-up sequences with new angles per email and graceful breakup.

💡

Pro tip: Follow-ups drive 60-70% of cold email replies. Each must add new angle, not repeat. Claude's narrative coherence maintains cohesion across all 4.

Breakup Email

7/20

<task>Write breakup email to unresponsive prospect</task> <context>[describe]</context> <output> - Subject: "Closing the loop" or similar - Acknowledge they're busy / not interested - State closing file - Leave easy out ("ping me in 3 months") - No guilt, no final pitch Max 80 words.

Writes graceful breakup emails with low-friction "come back" options.

💡

Pro tip: Breakup emails consistently get highest reply rate — sometimes 10-15%. Prospects who ignored everything suddenly reply. Loss aversion is real.

Post-Demo Follow-Up

8/20

<task>Follow up after demo with [prospect]</task> <discussed>[key points]</discussed> <next_step>[agreed]</next_step> <output> - Subject referencing call - Short recap - Specific value-add from conversation - Clear next step with date </output>

Writes post-demo follow-ups with specific conversation references and dated next steps.

💡

Pro tip: Include something specific from the conversation ("you mentioned team uses X — here's a resource about Y"). Shows you listened. Generic follow-ups die.

Re-Engagement Email

9/20

<task>Re-engage cold lead</task> <last_activity>[describe]</last_activity> <time_since>[weeks / months]</time_since> <output> - Acknowledge gap without apology - Share new + relevant (product update, case study) - Open-ended question - No pressure </output>

Writes re-engagement emails with fresh content and open-ended questions.

💡

Pro tip: Don't apologize for silence — it makes message about you. Just pick up where you left off. "Wanted to share something you'd find useful" > "Sorry for not reaching out sooner."

Trigger-Based Follow-Up

10/20

<task>Follow up on [trigger — promotion, hire, funding, launch]</task> <prospect>[describe]</prospect> <event>[specify]</event> <output> - Subject referencing trigger - Genuine acknowledgment (not congrats-spam) - Connect trigger to how I can help - Specific + soft CTA </output>

Writes event-triggered follow-ups tying news to natural offers.

💡

Pro tip: Trigger-based outreach gets 3-5× reply rate of cold. Promotions, funding, new roles, launches = legitimate reasons. Timing does half the work.

Strategy

5 prompts

ICP Definition

11/20

<task>Define ideal customer profile</task> <product>[describe]</product> <best_customers>[describe]</best_customers> <output> 1. 3-5 attributes of ideal customer 2. Where to find them (LinkedIn filters, tools) 3. Disqualifiers 4. Red flags 5. Scoring rubric </output>

Defines ICP with attributes, sourcing, disqualifiers, and scoring rubric.

💡

Pro tip: Broad ICPs = generic emails = low response. Specific ICPs let you write hand-written-feeling emails at scale. Narrow wins.

Campaign Design

12/20

<task>Design cold outreach campaign</task> <goal>[X meetings / leads]</goal> <icp>[describe]</icp> <output> 1. Volume math (conversion rates) 2. Daily send schedule (deliverability-safe) 3. Sequence structure 4. A/B test plan 5. Tooling 6. Metrics dashboard </output>

Designs cold email campaigns with volume math, schedule, sequence, and A/B testing.

💡

Pro tip: Cold email is math. 2,000 contacts × 40% open × 15% reply × 20% meeting = 24 meetings. Back into volume from your rates.

Personalization Variables

13/20

<task>Set up personalization data structure</task> <sources>[LinkedIn / site / news]</sources> <output> Spreadsheet format with: name, company, role, specific detail, pain point, trigger event. Ethical scraping guidance.

Sets up personalization data structures for cold outreach with ethical scraping.

💡

Pro tip: Best personalization variables: specific post they wrote, hire they made, stat from their site. Build repeatable process — never manually research every prospect.

Deliverability Setup

14/20

<task>Set up cold email deliverability</task> <current>[describe]</current> <goal>>80% inbox placement</goal> <output> 1. SPF, DKIM, DMARC 2. Domain warming schedule 3. Volume limits 4. Signal hygiene (no links email 1, no images) 5. List hygiene 6. Monitoring tools </output>

Sets up cold outreach deliverability with SPF/DKIM/DMARC, warming, and monitoring.

💡

Pro tip: Perfect emails to spam = zero replies. Warm your domain, start slow, sacrifice volume for placement in month 1.

Sequence Performance Analysis

15/20

<task>Analyze sequence metrics</task> <data>[open/reply per email]</data> <output> 1. Biggest drop-off per email 2. Subject lines earning opens 3. CTAs earning replies 4. Industry benchmarks 5. 3 experiments next week </output>

Analyzes cold email sequence performance with drop-off and experiment recommendations.

💡

Pro tip: Cold email metrics lie without benchmarks. Always compare to category, not industry-wide. Optimize weakest link in sequence.

B2B Specialized

5 prompts

Enterprise C-Level Email

16/20

<task>Write enterprise cold email to C-level</task> <title>[VP/C-level]</title> <company_size>[describe]</company_size> <offer>[describe]</offer> <output> Direct subject (no clever tricks), respect for time, specific outcome in $/%, credibility line, low-effort CTA. Max 100 words.

Writes enterprise cold emails respecting C-level time with specific outcomes.

💡

Pro tip: Enterprise buyers hate small-biz pitches. Write as equals. Dollar/% outcomes. Conservative credibility. Respect the time.

Multi-Threading Strategy

17/20

<task>Multi-thread into [company]</task> <primary>[describe]</primary> <output> 1. 3-5 roles to reach 2. Tailored email per role priority 3. Coordination without spam feel 4. Cross-reference handling 5. Timing </output>

Plans multi-thread outreach across 3-5 decision-makers with coordinated messaging.

💡

Pro tip: Single-threaded enterprise deals die. Multi-threading 3-5 decision-makers doubles close rates. Coordinate carefully.

Post-Event Follow-Up

18/20

<task>Follow up after [event]</task> <context>[our chat]</context> <output> - Subject referencing event - Warm opener recalling specific thing - Tie to actionable offer - Specific soft CTA Send within 48 hours.

Writes post-event follow-ups with specific conversation references and 48-hour sends.

💡

Pro tip: Post-event follow-ups die when sent 2 weeks late. Send within 48 hours while memory's fresh. Reference something specific they said.

Referral Request Email

19/20

<task>Ask client/connection for referral</task> <relationship>[describe]</relationship> <target_icp>[describe]</target_icp> <output> - Warm opener - Explicit referral ask with specific ICP - Make it easy: forwardable email they can paste - Acknowledge if no one comes to mind </output>

Writes referral request emails with specific ICPs and forwardable intros.

💡

Pro tip: Vague referral asks fail. "Know any SaaS founders 50-200 employees struggling with X?" succeeds. Write the intro FOR them.

Proposal Follow-Up

20/20

<task>Follow up on sent proposal</task> <proposal>[describe]</proposal> <days_silent>[describe]</days_silent> <output> - Warm opener - Acknowledge busy - Offer to clarify / discuss with team - Soft next step with date </output>

Writes proposal follow-ups with clarification offers and dated next steps.

💡

Pro tip: Proposal silence = internal blockers, not disinterest. Offer to help with those ("happy to discuss with anyone on your team") vs nagging for "thoughts."

Frequently Asked Questions

Claude's voice matching from samples makes cold emails feel like one person wrote them, not a template. Claude is also cautious about spammy language that triggers filters. For cold outreach at scale, Claude produces higher-quality copy than ChatGPT.

Yes, with structured inputs. Feed Claude each prospect's name, role, company, specific detail, and pain point — Claude generates genuinely personalized emails. Quality is upstream: garbage data = generic emails.

Generic blast is dead. Targeted + personalized + well-delivered still hits 15-30% reply rates for high-value B2B. The bar rose; winners invest in ICP + deliverability + copy. Spray-and-pray is punished.

3-5 optimal. 60-70% of replies come from follow-ups. Stop at 5 unless you have genuine news. Persistent nagging hurts brand.

Both. Multi-channel outreach gets 2-3× reply rates of single-channel. LinkedIn view + connect + email is the highest-converting sequence for B2B.
