I built Cold Email Pro — Write emails that convert

Building Cold Email Pro: A Personal Quest for Better Email Conversions

The Problem

As a senior developer, I've spent countless hours crafting emails to potential clients, only to be met with crickets. It wasn't until I started analyzing my email open rates and response rates that I realized I had a problem. My emails were getting lost in inboxes, and my conversion rates were abysmal. I tried tweaking my subject lines, personalizing my greetings, and even A/B testing different calls-to-action, but nothing seemed to work. I knew I needed a more systematic approach to writing emails that convert. That's when I started building Cold Email Pro.

What I Tried First

Before building Cold Email Pro, I tried using various email templates and tools, such as Mailchimp and Hubspot. While these tools provided some useful features, they were too generic and didn't cater to my specific needs. I needed a tool that could help me craft personalized, data-driven emails that would resonate with my audience. Unfortunately, these tools fell short, and I found myself spending more time tweaking templates than actually writing effective emails.

How I Built It

I built Cold Email Pro using a combination of React, Groq, Vercel, and Stripe. React provided a robust frontend framework, while Groq allowed me to easily manage my data and APIs. Vercel enabled me to deploy my application quickly and securely, and Stripe handled payment processing. One of the key features of Cold Email Pro is its ability to generate personalized email templates based on user input. Here's an example of how I implemented this feature using React and Groq:

import { groq } from 'next-sanity';
import { useState } from 'react';

const EmailTemplate = () => {
  const [template, setTemplate] = useState('');
  const [input, setInput] = useState({
    name: '',
    company: '',
    subject: '',
  });

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

  const handleInputChange = (event) => {
    setInput({ ...input, [event.target.name]: event.target.value });
  };

  return (
    <div>
      <input
        type="text"
        name="name"
        value={input.name}
        onChange={handleInputChange}
        placeholder="Name"
      />
      <input
        type="text"
        name="company"
        value={input.company}
        onChange={handleInputChange}
        placeholder="Company"
      />
      <input
        type="text"
        name="subject"
        value={input.subject}
        onChange={handleInputChange}
        placeholder="Subject"
      />
      <button onClick={fetchTemplate}>Generate Template</button>
      <textarea value={template} readOnly />
    </div>
  );
};

export default EmailTemplate;

This code snippet demonstrates how I used React and Groq to generate personalized email templates based on user input.

What I Learned

One surprising insight I gained from building Cold Email Pro was that users are willing to pay for a tool that provides real value, even if it's not the cheapest option. I initially thought that users would be price-sensitive and opt for free or low-cost alternatives. However, I found that many users were willing to pay a premium for a tool that could help them write effective emails and increase their conversion rates.
