Knowing warm vs cold email is important to understand the tone and approach you should take.

Step-by-Step Guide: How To Write A Cold Email

Let’s break down how to write a cold email into 6 simple steps.

Step 1: Do Your Research

Before you write, take time to learn about the person or business you’re emailing. In B2B cold email, this means understanding their company, pain points, and how your solution helps.

This is part of the 30 30 50 rule for cold emails? – 30% of your time should go to research.

How to start cold sales email if you don’t know the person?

Look at:

• Their LinkedIn profile
• Company website
• Blog or news articles

Use this to add a personal touch to your message.

Step 2: Write a Catchy Subject Line

The subject line decides if your email is opened. A good subject line is:

• Short (5–7 words)
• Clear and honest
• Related to the person or their work

This is a big part of how to write a cold email. Even the best cold email templates won’t work if your subject line is boring.

Examples:

• “Quick idea for [Company Name]”
• “Question about [specific topic]”
• “Loved your blog on [topic]”

Step 3: Personalize the Opening

Now that they opened your email, don’t start with a boring intro. Instead, start with something personal.

This follows the second part of the 30 30 50 rule for cold emails? – 30% personalization.

How to start cold sales email in a personal way:

• Mention something they wrote or did
• Give a compliment
• Talk about a common connection

Example:

“Hi [Name], I read your LinkedIn post about remote work. Really helpful!”

This is how you make your cold emailing efforts feel human.

Step 4: Get to the Point

Now tell them why you’re writing. Be clear and polite.

This is the value part – 50% of the 30 30 50 rule for cold emails?

Example:
“I help HR teams save time by automating hiring emails. I thought this might be useful for your team at [Company Name].”

This step is key in learning how to write a cold email that works.

Step 5: Offer Value

Before asking for anything, offer something useful. This could be:

• A helpful tip
• A free resource
• A short idea

Cold emailing is not about selling; it’s about helping first.

This also shows you understand the difference between warm vs cold email – cold emails must give more value upfront.

Step 6: End with a Call to Action

Don’t leave the email open-ended. Ask for something simple.

Examples:

• “Can we schedule a 10-minute call next week?”
• “Would you like to see a quick demo?”
• “Can I send you more details?”
• Keep your CTA (call to action) short and easy.

This final part completes your process of how to start cold sales emails and also confidently closes your email.
