20 tested prompts across 4 stages. Works with ChatGPT, Claude, and Gemini.

Most cold emails get deleted in under two seconds because they open with "I hope this finds you well" and spend three sentences on the sender before mentioning what they want. These prompts use Claude to write cold emails that open with relevance, keep it short, and make a specific ask that matches where the recipient is in their buying journey. This guide walks you through every stage of Claude for Cold Emails, from Research and Targeting all the way through Test and Improve, with a tested, copy-ready prompt at each step. Each stage targets a specific phase of the process so you always know exactly what to ask and what output to expect. Works with ChatGPT, Claude, and Gemini and any other major AI tool.
Stage 1
Sending to the right person with the right message is more valuable than sending to a hundred wrong people. These prompts help you target before you type.
Identify the right person to contact
I want to reach out to [COMPANY NAME] about [MY OFFER/PRODUCT]. I am not sure who the right person is to contact. Based on what I know: [DESCRIBE WHAT YOU KNOW — COMPANY SIZE, INDUSTRY, WHAT THEY SELL]. Help me figure out: which job title or role is most likely to care about this, what department they sit in, and how to find their name (LinkedIn search terms, company website sections, etc.).
Research a prospect for personalization
I want to send a cold email to [RECIPIENT NAME], who is [JOB TITLE] at [COMPANY]. Here is what I know about them: [PASTE LINKEDIN BIO, RECENT POSTS, COMPANY NEWS, OR ANY RELEVANT DETAILS]. Help me identify: one specific personalization hook I can use in the email that shows I actually researched them, a business challenge their company is likely facing that my offer addresses, and the strongest reason they would care about what I am selling.
Build a targeted prospect list criteria
I sell [DESCRIBE PRODUCT/SERVICE]. The best customers I have had share these characteristics: [DESCRIBE BEST CUSTOMERS]. Help me define the criteria for an ideal prospect list. What company size, industry, growth stage, and tech stack (if relevant) do I target? What signals in the market or their LinkedIn profile suggest they are actively looking for something like what I offer?
Identify the pain point to lead with
I am reaching out to [JOB TITLE] at [TYPE OF COMPANY]. My product or service helps with: [DESCRIBE WHAT YOU OFFER]. What is the most pressing pain point this persona is most likely experiencing right now that connects to what I offer? Help me phrase it in the language they would use themselves — not in my product terms, but in terms of the problem they wake up thinking about.
Find a timely reason to reach out
I want to cold email [RECIPIENT NAME / TYPE OF PERSON] at [COMPANY/TYPE OF COMPANY]. Reaching out "just to introduce myself" is a weak reason. Help me think of timely, specific triggers that would make this a good time to reach out. Consider: recent company news, industry trends, the time of year and budget cycles, product launches they have made, or hiring signals that suggest a relevant need.
Stage 2
Cold emails that get replies are short, specific, and make it easy to say yes. These prompts help you write each part.
Write a complete cold email from scratch
I am cold emailing [DESCRIBE RECIPIENT — JOB TITLE AND COMPANY TYPE]. My offer is: [DESCRIBE PRODUCT/SERVICE AND KEY BENEFIT]. The problem I solve is: [DESCRIBE THE PAIN POINT]. I found a personalization hook: [DESCRIBE WHAT YOU NOTICED ABOUT THEM]. Write a cold email that is under 100 words, leads with relevance not my company, has one clear CTA, and sounds like a human wrote it. Write three subject line options: one curiosity-based, one benefit-based, one referencing their specific context.
Write an opening line that gets attention
I need an opening line for a cold email to [DESCRIBE RECIPIENT]. I want to avoid the following openings: "I hope this finds you well," "My name is X and I work at Y," and "I came across your profile." Here is what I know about the recipient: [PASTE RESEARCH]. Write five different opening line options, each taking a different approach: one that names a specific problem, one that references something they said publicly, one that makes a bold claim, one that asks a question, and one that opens with a relevant insight.
Write the value proposition in one sentence
My product or service is: [DESCRIBE]. The main benefit I deliver is: [DESCRIBE]. My target recipient's biggest pain point is: [DESCRIBE]. Write the core value proposition in a single sentence for use in a cold email. It should be specific (not "we help companies grow"), immediately understood by someone in this role, and focused on the outcome rather than the feature. Write three variations.
Write a soft CTA that is easy to say yes to
I am writing a cold email for an initial outreach. I do not want to ask for a 30-minute call on a first touch — that is a big ask from a stranger. Write three alternative CTAs that are easier to say yes to. They should advance the conversation without being needy or vague. Consider: asking a yes/no question, offering a piece of value, or asking a single question that gauges interest.
Rewrite a cold email that is not working
Here is a cold email I have been sending that is getting low response rates: [PASTE EMAIL]. Diagnose what is wrong with it and rewrite it. Look for: too long, leads with the sender rather than the recipient, vague value proposition, hard CTA on first touch, too formal or too salesy. Rewrite it to be under 100 words, lead with the recipient's problem, and end with a soft, easy CTA.
Stage 3
Most replies come from follow-up, not the first email. These prompts help you write a sequence that adds value each time without being annoying.
Write a three-email cold outreach sequence
I want to write a three-email sequence for cold outreach to [DESCRIBE RECIPIENT]. My offer is: [DESCRIBE]. Here is my first email: [PASTE OR DESCRIBE FIRST EMAIL]. Write emails 2 and 3. Email 2 (sent 3-4 days later): adds a piece of value (insight, case study, relevant resource) rather than just following up. Email 3 (sent 5-7 days later): a short, direct breakup email that makes it easy for them to reply even if they are not interested right now. All under 75 words each.
Add value in a follow-up without being annoying
I sent an initial cold email to [RECIPIENT TYPE] about [TOPIC] and have not heard back. I want to follow up but not just say "bumping this up." Here is context about their business or situation: [DESCRIBE]. Write a follow-up email that leads with a piece of value relevant to them — an insight, a stat, a resource, or a question that they would find interesting regardless of whether they buy from me. End with a gentle ask.
Write a cold email follow-up that handles objections
My cold email to [RECIPIENT] got this response: [PASTE RESPONSE]. They are interested but [DESCRIBE OBJECTION OR HESITATION — TOO EXPENSIVE / NOT THE RIGHT TIME / NEED APPROVAL / ALREADY HAVE A SOLUTION]. Write a reply that acknowledges their situation honestly, addresses the specific objection without being dismissive, and proposes a next step that lowers the barrier to saying yes.
Write a breakup email
I have sent [NUMBER] emails to [RECIPIENT NAME] without a response. Write a short, professional breakup email that: acknowledges this is my last message, does not guilt them, leaves the door open if timing changes, and is direct enough that they might actually reply because they feel the conversation is ending. Under 50 words.
Build a 30-day cold email cadence
I want to build a 30-day outreach cadence for a new prospect. My offer is: [DESCRIBE]. I want to touch them multiple times without being overbearing. Design a 30-day sequence with timing (Day 1, Day 4, Day 8, etc.) and a brief description of each touch: initial email, follow-ups that add value, a break, a re-engagement, and a final close. No single touch should feel like spam.
Stage 4
Cold email is a numbers game shaped by iteration. These prompts help you test systematically and fix what is not working.
A/B test two cold email approaches
I want to A/B test two versions of a cold email for [AUDIENCE]. Version A (my current approach): [PASTE OR DESCRIBE]. Write Version B that takes a meaningfully different approach — different opening, different value framing, or different CTA. Explain what hypothesis Version B is testing and what a statistically meaningful result would look like for a list of [APPROXIMATE NUMBER] contacts.
Diagnose low reply rates
My cold email campaign has: open rate [X%], reply rate [X%], and positive reply rate [X%]. Here is the email and subject line I am using: [PASTE]. Diagnose the most likely reason for the low performance. Is it the subject line (low opens), the email itself (opens but no replies), or the offer/targeting (replies but no interest)? Give me the top two changes to make first.
Personalize at scale with a template framework
I want to send cold emails to [NUMBER] prospects in [INDUSTRY]. I cannot personalize every email from scratch. Help me create a template with three or four fill-in-the-blank personalization variables that I can fill in for each prospect in under two minutes. The template should feel personal even though it is a template. Include the variable types I should research for each prospect (e.g., recent announcement, relevant job post, shared connection).
Improve deliverability and avoid spam filters
My cold emails are getting low open rates despite a clean list. I suspect deliverability issues. Review these elements of my email setup and copy: [DESCRIBE — SEND DOMAIN, VOLUME, EMAIL CONTENT]. What are the most likely deliverability issues? What technical checks should I do (SPF, DKIM, DMARC, domain warm-up)? What language or structure in the email content should I change to avoid spam filters?
Write subject lines for higher open rates
I am cold emailing [DESCRIBE TARGET AUDIENCE] about [TOPIC]. Write ten subject line options and rate each one on: likely open rate (low/medium/high), risk of spam trigger, and fit for a professional audience. Explain what makes the highest-rated ones work. Include a mix of: short and punchy, question-based, personalized (with a placeholder), and curiosity-based.
Under 100 words for initial outreach. The longer the email, the lower the reply rate. Every sentence should earn its place. If you cannot explain why your email matters to the recipient in under three sentences, you have not figured out your value proposition yet.
Claude is strong at cold email copy because it can match tone, avoid cliches, and write like a human. The key is giving it specific inputs: who you are reaching out to, what problem you solve, and one piece of personalized research. Generic inputs produce generic emails.
Three to five touches across 30 days is a reasonable cadence. More than that and you risk annoying people and damaging your sender reputation. Make each follow-up add something new — a piece of value, a case study, a question — rather than just repeating your pitch.
Short, specific, and about the recipient rather than you. "Quick question about [their company]" and "[Their name] — [relevant insight]" typically outperform long, benefit-heavy subject lines. Test both curiosity-based and direct approaches.
Warm up new sending domains slowly, authenticate with SPF/DKIM/DMARC, avoid spam trigger words (free, guaranteed, act now), keep your list clean and remove bounces immediately, and maintain a reasonable email volume per day per domain.
