Cold emailing undeniably remains the best way to build relationships with prospects.
But letās face it. Getting a response is often not that easy.
Your emails need to resonate without sounding too salesy, or they'll end up in the spam folder.
However, personalizing each email to every prospect can be time-consuming. So, is there a way to write genuine, personalized emails and reach more prospects efficiently?
Absolutely, and AI is the answer.
In this guide, Iāll show you how to leverage ChatGPT to write effective cold emails and reach more people in less time. Weāll focus on using Clay to streamline the process, and then send them using Instantly.

Using AI to Customize Cold Email First Lines
Step 1: Set Up Your Table on Clay
First, youāll need to log in to your Clay account. On your dashboard, click āNew Table.ā Then, import a CSV file containing the list of companies youāre interested in.
For this tutorial, Iāve prepared a list of companies with their important details like LinkedIn profiles and contact information of decision-makers.

Step 2: Enrich Company Name
Our goal is to contact decision-makers with customized email first lines based on the companyās LinkedIn description.
So, letās add an enrichment by clicking on the table. Then, look for the āClaygentā plugin, as shown below.

Claygent helps you scour public information about your leads from across the web, including company descriptions.
Now, go ahead and select it to open the settings tab.
Note: Make sure you have an OpenAI API Key. If you donāt have one, I suggest you set up an account on OpenAI Platform. Once logged in, go to your profile settings, click the dropdown menu, and select āView API Keys.ā

From here, youāll need to generate the API key and copy it. Then, go back to Clay and paste it to the API field on the integration settings, as shown below.

Next, scroll down to the āMissionā text area. Here, youāll need to prompt ChatGPT to search for the companyās LinkedIn description. Make sure that your instructions are clear and specific to get good results.
Hereās what my prompt looks like:
Find the LinkedIn Description of the company. This should contain the company's objective summarized in a few words.
Here's the company's name: /Company Name
Here's the company's LinkedIn URL: /LinkedIn URL
Now, you'll need to pick a GPT model to process your prompt. I always prefer GPT-4 because it produces a higher quality response than the older model.

Once you've made your choice and checked your settings, click save and run.
Hereās what our table looks like. Notice that Iāve labeled the new column āMissionā because it contains the mission objective of the company.

Step 3: Write An Effective AI ChatGPT Prompt
Now that we have the companyās description, letās write a ChatGPT prompt to customize our cold emails.
I honestly find this part a bit tricky. Thatās because it needs a bit of creativity and precision to get ChatGPT to generate that perfect email text. After all, no one wants a drawn-out, robotic email ā it's a quick way to lose your prospectās interest.
In this tutorial, it actually took me a few iterations to finally produce a better email.
Hereās how I did it.
First, I added an enrichment on my table by clicking the āAdd Columnā and then āEnrich Data.ā Under the āEnrichmentsā tab, I selected āUse AI (ChatGPT).ā

Then, I typed my AI prompt in the provided text area.

When you first enter your prompt, you might not get good results right away. I noticed that ChatGPT can sometimes give weird responses, especially if your prompt isnāt very detailed. Youāll need to iterate the prompt several times to produce human-like responses.
Writing a good prompt requires practice. Here are a few tips to help you out:
- State what you need. If itās an email based on your prospectās company description, mention it in your prompt.
- Your prompt should be very specific. Add as many details as you can, like the information you want to add, the number of words, the contactās name, etc.
- Specify your inputs. You can add the contactās name or LinkedIn information. For example, your ChatGPT prompt could include something like this: āThis is the companyās LinkedIn description: /[input]ā
- Describe the output that youāre expecting. For instance, you can tell ChatGPT to use a casual or friendly tone.
For this example, Iāve crafted the following prompt (you can use this as your starting point):
Pretend that you are a sales professional. First, I want you to write a warm email showing your interest in the client's company mission. But don't overdo it. Follow this up by introducing your company's digital marketing services and how they might help the client. Focus on how they can benefit from the services, not the features. Please make it short, around 100 - 150 words. Use a friendly, casual tone when writing the email. Please personalize the email subject based on the company's mission.
The client's name is this: /Name - People
The company mission is this: /Mission
Your name is this: Christy
Once youāre satisfied, click āContinue to Add Fields.ā Then, save and run the integration.
You should now see a new column added with the AI-generated text.
Hereās a sample output from ChatGPT:

Step 4: Send Your Cold Email to Instantly
Now that you've got your AI-drafted emails, let's send them out with Instantly.
Enrich your table by selecting the āAdd Lead to Campaignā integration.

On the settings tab, connect your Instantly account using an API key.
You can get your API by opening the profile settings on your Instantly account. Go to the āIntegrationsā tab and then click āCopy API Key.ā

Back in Clay, click āChoose Instantly API key Accountā and select āAdd an account.ā Then, paste in the API key.
Next, youāll need to specify your Instantly campaign. Simply choose the name of your campaign from the dropdown list.
If you don't have one in Instantly, quickly create one and then select its name in Clay. Donāt forget to click the āRefresh fieldsā to see the newly added campaign from the dropdown.


Then, point to the 'Validated Work Emails' column when asked for the 'Email' field.

Next, check your campaign in Instantly. Go to the āLeadsā tab. You should find the list of emails imported from Clay. Now, youāre ready to send your cold emails!

Tips to Create Compelling Email First Lines
Emails have long been an important channel for businesses to engage with clients.
Therefore, your opening line is crucial. You need to nail that to entice the recipient to continue reading. You need to maximize its impact to increase your response rate.
AI tools like ChatGPT might be making our tasks a bit easier. But still, youāll need the right approach to make your emails more effective.
Here are a few tips I find very helpful in creating personalized cold emails:
- Keep the tone casual yet professional. Remember, your first email is an introduction. So while you want to be approachable, you also need to exude professionalism. Starting with a āHey, what's up!ā might be too laid back. Aim for a balance that's friendly but also respects the boundaries of a new business relationship.
- Show genuine interest. For example, mentioning your prospectās company mission can pique their interest in return.
- Keep your email short. Aim for 50-150 words. Time is precious, and a concise email respects that.
- Donāt make your email forced and salesy.
- Be genuine. If your AI-generated text sounds too robotic, take the time to revise and add a personalized touch.
Thatās A Wrap!
AI has truly revolutionized the way we do business in the 21st century. With ChatGPT and Clay, you can quickly craft cold emails and customize them for specific clients.
And its capabilities don't end here.
