I built Cold Email Writer — Write cold emails that convert

Building a Cold Email Writer: A Personal Journey

As a senior developer, I've spent countless hours writing cold emails to potential clients, trying to convince them to give my services a shot. But let's be honest, writing effective cold emails is a daunting task. It's a delicate balance between being persuasive and not coming across as spammy. I've lost count of how many times I've stared at a blank screen, trying to craft the perfect email that would convert. My personal story with cold emails began when I started my own consulting business. I would spend hours researching potential clients, crafting personalized emails, and waiting for a response that often never came. It was frustrating, to say the least.

One particular instance that stands out was when I spent an entire day researching a potential client, only to receive a rejection email that stated my services weren't a good fit. It was disheartening, but it made me realize the importance of personalization and research in cold emailing. I began to experiment with different email templates, trying to find the perfect balance between being informative and being concise. But it wasn't until I started building my own cold email writer tool that I realized the true potential of automation in cold emailing.

What I Tried First

Before building my own tool, I tried using existing solutions like Mailchimp and Hubspot. However, I found that these tools were too generic and didn't allow for the level of personalization I needed. I also experimented with AI-powered email writing tools, but they often produced emails that sounded robotic and unconvincing. Specifically, I tried using tools like Yesware and Boomerang, but they didn't quite fit my needs.

How I Built It

I decided to build my own cold email writer using React, Groq, Vercel, and Stripe. I chose React because of its flexibility and ease of use, while Groq provided a powerful querying language for my data. Vercel allowed me to deploy my app quickly and easily, and Stripe handled payments and subscriptions.

One of the technically challenging parts of building the app was creating a robust algorithm for generating personalized email templates. I used a combination of natural language processing (NLP) and machine learning to analyze the user's input and generate a tailored email template. Here's a snippet of the code that handles this:

import { groq } from 'groq';
import { useState, useEffect } from 'react';

const EmailTemplate = () => {
  const [template, setTemplate] = useState('');
  const [input, setInput] = useState('');

  useEffect(() => {
    const generateTemplate = async () => {
      const query = groq`
        *[_type == "emailTemplate" && category == $category] {
          template
        }
      `;
      const params = { category: input };
      const response = await fetch('/api/groq', {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify({ query, params }),
      });
      const data = await response.json();
      setTemplate(data.result[0].template);
    };
    generateTemplate();
  }, [input]);

  return (
    <div>
      <input
        type="text"
        value={input}
        onChange={(e) => setInput(e.target.value)}
        placeholder="Enter company name"
      />
      <p>{template}</p>
    </div>
  );
};

This code uses the Groq library to query a database of pre-built email templates and generates a personalized template based on the user's input.

What I Learned

Building the cold email writer tool taught me several valuable lessons. Firstly, I learned that users are willing to pay for a tool that saves them time and effort, even if it's a relatively simple solution. I also learned that pricing is a delicate balance between being competitive and being profitable. Initially, I priced my tool too low, and it wasn't until I raised the price that I started to see significant revenue growth. For example, I found that users were more likely to pay for a tool that offered a free trial, rather than a tool that required a upfront payment.
