The Body Copy

Once you have written your headline, you must craft your email body. 

At the start of this Cold Email Masterclass, we mentioned converting a cold lead into a prospect who wants to talk to your business is a high-touch activity.

We also know that emails that evoke responses are relatively short. 

Putting the above together, from your first email to your final follow up emails, you need to constantly demonstrate value to the prospect, engaging with them and buying their mind-share.

To better understand how to write a body copy, let’s break it down into 5 parts.

Email body

Opening Line

Working professionals receive an average of 80 emails each day, they might not open each email, and even if they do open it, they simply scan the email all the way to the end. So your opening line needs to grab attention

Some examples that can help you get started are:

  • “I noticed you’re {mention something relevant about their company or industry}, and I have an idea that could help.”
  • “Ever wondered how to {solve a common problem in their industry}? We’ve got the answer”.
  • “Did you know that {eye-catching industry statistic}? We can help you turn that around.”
  • “Your recent achievements in {mention something they’ve done well} caught our attention, and we believe we can complement your success.”

Email Body

When it comes to writing the email body copy, think about how you can make it really valuable for your prospect (your value proposition). The key is to focus on what matters to them. It should be prospect-centric, clear and easy for the prospect to understand and respond to. 

Don’t try to over-personalise or show extra empathy. A prospect can read through all the bs.

“They keep their eye on the ball. Meeting booked moves the needle, not clicks.

Sales engagement platforms like SmartReach focus on email deliverability to get you more responses.” 


Add a clear call to action (CTA) in your email. It should tell your prospect what to do or evoke a response. Avoid having multiple CTAs as it might confuse the prospect..

Here are a few examples

  • “Join us for a webinar this Friday?”
  • “Click here to explore our latest products.”
  • “Request a quote to get started.”
  • “Download the free e-book now.”

“Would you like a case study of an agency that scaled meetings using this strategy? Reply “yes”. Shall email it to you”

Email Signature

Your email signature is your digital business card. It’s a subtle yet crucial element in cold emails, helping you appear professional, approachable, and trustworthy. Keep it concise and friendly, and it’ll leave a positive impression on your recipients.

Techniques from copywriting

The following copywriting techniques can be applied : 

  1. AIDA – draw Attention, create Interest, evoke Desire, and then, finally, a call to Action
  2. ACCA – Awareness, Comprehension, Conviction, Action
  3. 4Ps – Picture, Promise, Prove, Push ( call to action) 

Your initial emails may be a mental action from your prospect, like acknowledging a problem exists. But your follow ups slowly add value and amplify the desire in their mind for the solution that you have. Notice that all the above 3 techniques end with a call to action. 

Eye Relief

One of the tips from Bond Halbert – is providing Eye Relief: Sentences and paragraphs that are short and easy to read, separated by whitespace. 

This paragraph is deliberately hard to read. It has words that are longer than the average and will make you want to skip ahead because it will appear as a wall of text and a much higher load on your brain’s frontal lobe, and the second sentence is very long.

‘At times, he may indulge himself with a long one, but he will make sure there are no folds in it, no vaguenesses, no parenthetical interruptions of its view as a whole; when he has done with it, it won’t be a sea-serpent with half of its arches under the water; it will be a torch-light procession. [Mark Twain example]


Personalizing an email will garner a higher response. Researching your Prospect on LinkedIn, a LinkedIn Post or article they have shared,  or if they maintain a blog will give good ideas to open a conversation.

Adding Conviction

Testimonials from customers, customer outcomes, case studies, and whitepapers can all be part of the follow up emails that attract your Prospect’s attention and your product or service’s potential outcome for their business.

Follow ups Emails

Now, you may wonder why we talking about follow-up emails in this lesson. Well, its simple. The best practices for writing the initial email and follow-up emails are the same. And we didnt want waste your time. So, capturing only a few key best practices here.

If you visited a showroom for a product you were just introduced to today, would you buy it on your first visit? 

This may surprise you, but you may want to maintain at least 10 follow ups. The Business News Daily talks about persistence in sales follow ups. Your first email will work with your follow up emails to convince your Prospect of the value proposition. Reinforcing the argument made by Jeb Blount in “fanatical Prospecting”, it takes between 20 to 50 touchpoints to convert a cold prospect into someone who wants to interact with your business. 

Of course, the number of touchpoints needed to convert a customer will vary depending on the industry, the product or service being offered, and the buyer persona. However, Blount’s advice is a good starting point for salespeople who want to increase their conversion rate.

So, more follow-ups, more replies, no follow-ups, no replies.

Your follow up email is a reminder in case your prospects missed out on replying. It’s a polite way of saying, “Hey, remember me? Can we talk more about this?”. 

If I had to sum up the best practices for cold email follow-ups

  • Be brief and to the point.
  • Highlight the KEY benefit for the prospect
  • Make it easy for the prospect to respond.
  • Reply in the same thread
  • Timing is crucial provides a report that shows the best time to send
