First-Touch
5 promptsPersonalized Cold Email
1/20✨ What it does
Claude writes a personalized cold email to [prospect] with a research-specific subject, a pain-framed pitch, and a soft CTA. Paste [paste LinkedIn/site/recent post details] and [paste your best past cold emails if available], then send only after the opener still sounds like you.
<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.
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✨ What it does
Claude generates 10 cold-email subject lines across curious, personalized, benefit, referral, and low-pressure pairs, each with preview text, an open-rate guess, and a spam check. [describe] the offer, then test two subjects and keep the one that earns opens.
<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.
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✨ What it does
Claude writes 15 opener lines that cite specific details and rank them by how authentic they sound. Sketch the prospect in [describe] using [LinkedIn, content, company news], then pick an opener that still leads cleanly into your pitch.
<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.
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✨ What it does
Claude writes a give-before-ask cold email that shares an [insight / audit / resource] and does not pitch in this send. Keep the future offer off the page, then mail only the value and a polite close.
<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>
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✨ What it does
Claude writes a 50-80 word cold email with a specific subject, a personalized opener, a one-line pitch, and a one-sentence CTA. Put the prospect and offer in [describe], then send it without bullets or a logo in the signature.
<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.
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 prompts4-Email Follow-Up Sequence
6/20✨ What it does
Claude writes a 4-email follow-up for days 3, 7, 14, and 21, each with a new angle, a shorter body, a specific subject, and one CTA, ending in a graceful breakup. [describe] the original note, then queue the four and delete any "just following up" line.
<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.
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✨ What it does
Claude writes a breakup email under 80 words that closes the file, leaves an easy "ping me in 3 months" out, and skips guilt or a last pitch. [describe] the context, then send it and stop chasing that thread.
<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.
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✨ What it does
Claude writes a post-demo follow-up to [prospect] with a subject that names the call, a short recap, a value-add from the chat, and a next step with a date. Add [key points] and the [agreed] next step, then send it the same day.
<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>
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✨ What it does
Claude writes a re-engagement email that names the gap without apologizing, shares something new, and asks an open question with no pressure. [describe] the last activity and how many [weeks / months] have passed, then send it once and wait.
<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>
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✨ What it does
Claude writes a trigger follow-up that names the event, thanks them without spammy congratulations, and ties the news to a soft way you can help. Fill [describe] with the prospect and [specify] the event, then send it while the news is still fresh.
<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>
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 promptsICP Definition
11/20✨ What it does
Claude defines an ideal customer profile with 3-5 attributes, where to find them, disqualifiers, red flags, and a scoring rubric. Load the product and best customers into [describe], then score the next list you pull with that rubric.
<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>
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✨ What it does
Claude designs a cold-outreach campaign toward [X meetings / leads], with volume math, a deliverability-safe daily send schedule, sequence structure, A/B tests, tooling, and a metrics dashboard. [describe] the ideal customer, then set the daily cap you can actually keep.
<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>
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✨ What it does
Claude sets up a personalization spreadsheet with name, company, role, a specific detail, a pain point, and a trigger event, plus ethical scraping notes. Pull rows from [LinkedIn / site / news], then fill only details you would be fine saying out loud.
<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.
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✨ What it does
Claude builds a deliverability plan for over 80 percent inbox placement, covering SPF, DKIM, DMARC, domain warming, volume limits, signal hygiene, list hygiene, and monitoring. [describe] your current setup, then fix authentication before you raise volume.
<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>
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✨ What it does
Claude reads [open/reply per email], names the biggest drop-off, which subjects earn opens, which CTAs earn replies, and three experiments for next week. Compare the notes to the benchmarks, then run the first experiment on the weakest email.
<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>
Pro tip: Cold email metrics lie without benchmarks. Always compare to category, not industry-wide. Optimize weakest link in sequence.

B2B Specialized
5 promptsEnterprise C-Level Email
16/20✨ What it does
Claude writes a C-level cold email under 100 words with a direct subject, a specific dollar or percent outcome, a credibility line, and a low-effort CTA. Name the [VP/C-level] title and [describe] company size and offer, then cut any clever trick before you send.
<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.
Pro tip: Enterprise buyers hate small-biz pitches. Write as equals. Dollar/% outcomes. Conservative credibility. Respect the time.
Multi-Threading Strategy
17/20✨ What it does
Claude plans a multi-thread into [company] across 3-5 roles, with a tailored email per role, coordination so it does not feel like spam, cross-reference handling, and timing. [describe] the primary contact, then send the first role email before the others.
<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>
Pro tip: Single-threaded enterprise deals die. Multi-threading 3-5 decision-makers doubles close rates. Coordinate carefully.
Post-Event Follow-Up
18/20✨ What it does
Claude writes a post-[event] follow-up that recalls [our chat], ties it to a concrete offer, and ends on a soft CTA meant to send within 48 hours. Check the remembered detail, then mail it before the event goes cold.
<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.
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✨ What it does
Claude writes a referral request with a warm opener, a specific person to look for, a forwardable intro they can paste, and an easy out if no one comes to mind. Name the relationship and the target in [describe], then send the forwardable block as-is if it still sounds like you.
<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>
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✨ What it does
Claude writes a proposal follow-up that acknowledges they are busy, offers to clarify with the team, and suggests a soft next step with a date. [describe] the proposal and how many days they have been silent, then send it once and put the date on your calendar.
<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>
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."
