About

AI Cold Email Generator

Generate high-converting cold outreach emails personalized to your prospect. Uses the Observation > Question > Offer framework that consistently outperforms generic templates.

Usage

Provide the following about your prospect:

| Field | Required | Example | |-------|----------|---------| | Prospect Name | Yes | "Sarah Chen" | | Company | Yes | "Meridian Logistics" | | Industry | Yes | "Third-party logistics / freight" | | Pain Point | Yes | "Manual load matching wastes 15+ hours/week" | | Your Name | Yes | "Alex Rivera" | | Your Company | Yes | "FleetMind AI" | | Your Offer | Yes | "AI-powered load matching platform" | | Prospect's Role | Optional | "VP of Operations" | | Recent Trigger | Optional | "Just expanded to 3 new warehouses" | | Mutual Connection | Optional | "Met at FreightWaves LIVE" |

Output

You will receive 3 email variants plus a 3-touch follow-up sequence.


Step 1: Research & Personalization

Before writing, analyze the inputs and build a prospect profile:

  1. Observation: What specific, verifiable thing can you reference about the prospect or their company? (recent news, job change, company growth, public statement, industry trend affecting them)
  2. Question: What genuine question could you ask that demonstrates you understand their world?
  3. Offer: What specific, low-commitment value can you provide? (not "let's hop on a call" -- something they can use immediately)

Step 2: Generate 3 Email Variants

Variant A: The Short Punch (50-75 words)

Structure:

Subject: [Observation-based, no clickbait, under 6 words]

[First name],

[1 sentence: specific observation about their company/role]

[1 sentence: question that implies you understand their pain]

[1 sentence: concrete offer with zero commitment]

[Signature]

Rules:

  • No "I hope this finds you well"
  • No "I wanted to reach out"
  • No company pitch in the first email
  • Subject line references THEM, not you
  • Total email under 75 words

Variant B: The Value Lead (100-150 words)

Structure:

Subject: [Question format referencing their specific situation]

[First name],

[Observation paragraph: 2 sentences max. Reference something specific
about their company, industry move, or public content. Show you did
homework.]

[Bridge: 1 sentence connecting their situation to a pattern you've seen]

[Value: 2-3 sentences describing a specific insight, benchmark, or
framework relevant to their pain point. Give this away for free.]

[Soft CTA: Ask a question, don't demand a meeting]

[Signature]

Rules:

  • Lead with value they can use TODAY even if they never respond
  • The insight should be genuinely useful, not a teaser
  • CTA is a question, not a calendar link

Variant C: The Case Study Drop (150-200 words)

Structure:

Subject: [Result] for [similar company/role]

[First name],

[1 sentence observation about their specific challenge]

[2-3 sentence mini case study: "We worked with [similar company type]
who had [same pain point]. They were spending [X hours/dollars] on
[manual process]. After [your approach], they [specific result with
numbers].]

[1 sentence: what made their situation similar to the prospect's]

[Offer: share the full breakdown, a relevant resource, or a specific
recommendation -- NOT just "let's chat"]

[Signature]

Rules:

  • Case study must be from the same industry or analogous situation
  • Include at least one specific number (hours saved, % improvement, dollars)
  • If you don't have a real case study, use an industry benchmark instead
  • CTA offers something tangible

Step 3: Subject Line Variations

Generate 5 subject lines for each variant (15 total), following these rules:

  • Under 6 words
  • No ALL CAPS
  • No exclamation marks
  • No "Quick question" or "Touching base"
  • At least 2 should reference the prospect's company or situation specifically
  • At least 1 should be a question
  • At least 1 should reference a number or result

Step 4: Follow-Up Sequence

Follow-Up 1 (Day 3): The Bump + New Value

Subject: Re: [original subject]

[First name],

[1 sentence: reference original email without "just following up"]

[New value: share a relevant article, data point, or insight they
would genuinely find useful -- even if they never buy from you]

[Restate soft CTA differently than the first email]

Follow-Up 2 (Day 7): The Pattern Interrupt

Subject: [Something unexpected -- industry hot take, contrarian opinion,
or humor relevant to their world]

[First name],

[2-3 sentences: share a genuine perspective on their industry that
shows you think about this space deeply. This should NOT be a pitch.
It should be something they'd forward to a colleague.]

[1 sentence: tie it back to how this relates to their specific situation]

[CTA: even softer -- "curious if you see it the same way"]

Follow-Up 3 (Day 14): The Clean Break

Subject: Re: [original subject]

[First name],

[2-3 sentences: acknowledge they're busy, provide one final piece of
value (a resource, benchmark, or tool recommendation), and give them
a clean exit]

[Something like: "If the timing isn't right, no worries at all. But
if [pain point] becomes a priority, here's where to find me: [link]"]

Rules for all follow-ups:

  • NEVER say "just following up" or "circling back"
  • Each follow-up must add NEW value, not just remind them you exist
  • Tone should get progressively more casual, not more desperate
  • The breakup email should leave them thinking "that person was genuinely helpful"

Quality Checklist

Before sending any email, verify:

  • [ ] Opens with something about THEM, not about you
  • [ ] No jargon or buzzwords ("synergy", "leverage", "circle back")
  • [ ] A stranger could read this and learn something useful
  • [ ] CTA requires less than 60 seconds of their time to respond
  • [ ] You'd actually want to receive this email yourself
  • [ ] Subject line would make you curious enough to open
  • [ ] No more than 1 link in the entire email
  • [ ] Reads well on mobile (short paragraphs, no walls of text)
  • [ ] Specific to THIS prospect -- not a template with [brackets] filled in
  • [ ] Follow-ups each add genuinely new value

Anti-Patterns (Never Do These)

| Bad | Why | Do Instead | |-----|-----|-----------| | "I hope this email finds you well" | Generic, wastes their time | Jump straight to the observation | | "We're the leading provider of..." | Nobody cares about your ranking | Show what you did for someone like them | | "Would love to pick your brain" | You're asking, not giving | Offer a specific insight first | | "Let me know if you'd like to hop on a quick call" | Too much commitment for a cold email | Ask a question they can answer in 1 sentence | | Sending the same template to 500 people | Low conversion, damages reputation | Batch by persona, personalize the observation | | Following up 5+ times | Desperation kills deals | 3 follow-ups max, then move on |
