Writing Prompts for High-Converting AI Emails

Introduction

AI tools like ChatGPT, Gemini AI, and Grok have transformed the way salespeople and founders approach cold email writing. But while the tools are powerful, the results you get depend heavily on the prompts you feed them.

Great prompts = great emails.

In this guide, we’ll break down:

  • What makes a good AI email prompt
  • 10+ high-performing cold email prompts for GPT, Gemini, and Grok
  • Real email outputs generated using these prompts
  • Tips to improve personalization and conversions

Let’s turn your AI tools into email conversion engines.

What Makes a Prompt “High-Converting”

A good prompt should be:

  • Specific: Include your goal, tone, and context.
  • Targeted: Include recipient’s industry, pain point, or job title.
  • Brief but informative: Enough info to guide the AI, not confuse it.

For cold emails, your prompt should cover:

  • Who you are
  • What your company/product does
  • Who the recipient is
  • What problem you solve
  • Your desired CTA (meeting, reply, resource click, etc.)

High-Converting AI Email Prompts (With Outputs)

Prompt 1: Founder's Cold Email to a SaaS VP

“Write a 60-word cold email from a SaaS founder named Ankit, introducing a new AI tool that automates outbound emails. Target audience is a VP of Sales at a 50-200 employee tech company. Make it sound human, not robotic. Include a soft CTA.”

Prompt 3: Grok-Optimized Prompt for Outbound SDR

“As an AI SDR, craft a 3-step cold email sequence for reaching out to HR heads in India for a SaaS company selling employee wellness programs. Tone should be concise, helpful, and human.”

Grok Output:

Email 1:
Hey [First Name], just saw your team’s growth. Quick idea: we help HR leaders like you reduce burnout and improve retention with personalized wellness nudges. Worth a chat?

Email 2 (3 days later):

Gemini Output:

Just popping in — saw you checked out my last email and didn’t want to drop the ball. Worth chatting for 10 mins this week?

Prompt 6: Product Demo Outreach (Remo Style)

“Write an email introducing Remo, an AI sales agent who finds leads, qualifies them, personalizes emails, and books meetings. Make it sound fun, not too salesy.”

GPT Output:

“Reply to a prospect who says ‘this sounds great but we don’t have budget right now.’ Be empathetic and offer a no-pressure check-in in 60 days.”

GPT Output:

Totally get it, [First Name] — timing’s everything. How about I check back in a couple months? In the meantime, I’ll send over a playbook that might help your team now.

Prompt 9: Writing In Different Tones

“Write 1 email in 3 tones: funny, formal, and casual. Email is about offering a free AI email audit.”

Funny:
What if your emails got replies faster than your boss on Slack? Let’s do a free AI audit and check. Worst case: we laugh. Best case: you 3x replies.

Formal:
I’m reaching out to offer a complimentary review of your outbound emails. We’ll assess tone, conversion, and structure — no strings attached.

Prompt 10: Hyper-Personalization from LinkedIn

“Write a cold email referencing a prospect’s recent LinkedIn post about scaling their GTM team. Offer a solution to help.”

Gemini Output:

Loved your recent post on GTM hiring — especially the bit about choosing hustle over headcount. We built Remo to be the AI teammate who does the hustle for you. Can I show you how?

Bonus Tips to Make Prompts Even More Effective

  • Include recipient role + company size
  • Mention specific product benefits
  • Say how long the email should be (e.g. 60 words)
  • Mention tone (funny, serious, casual, etc.)
  • Ask for one email or a sequence

Final Thoughts: Use AI Like a Pro, Not a Bot

AI tools like GPT, Gemini, and Grok are powerful — but they’re not mind-readers. Feed them quality prompts and they’ll give you cold emails that open, convert, and even spark replies like:

“This didn’t feel like a cold email. When can we talk?”

That’s when you know you’re doing it right.

And if you’d rather skip the prompting and let an agent do it all for you? That’s what Remo, our AI sales agent, is built for — from prompt to personalization to meeting booked.

Until then — copy, paste, and prompt your way to better cold emails.
