Promail source code

Promail is a popular email marketing software that allows users to create and send targeted email campaigns to their subscribers. The source code for Promail is not publicly available, as it is a proprietary software owned by its developers.

However, I can provide you with some information on how Promail works and its architecture. Promail is built using a combination of technologies such as:

1. Front-end: HTML, CSS, JavaScript, and React
2. Back-end: Node.js, Express.js, and MongoDB
3. Database: MongoDB

Here's a high-level overview of the Promail architecture:

1. User Interface: The user interface is built using React, which provides a responsive and interactive interface for users to create and manage their email campaigns.
2. API: The API is built using Node.js and Express.js, which provides a RESTful interface for the front-end to interact with the back-end.
3. Database: The database is built using MongoDB, which provides a scalable and flexible storage solution for storing user data, email campaigns, and other relevant information.
4. Email Server: Promail uses an email server to send and receive emails. The email server is responsible for handling email delivery, tracking, and analytics.
5. Queue: Promail uses a queue system to manage the sending of emails. The queue system ensures that emails are sent in a timely and efficient manner.

Here's a simplified example of the Promail source code:

// Front-end (React)
import React, { useState, useEffect } from 'react';
import axios from 'axios';

function App() {
  const [campaigns, setCampaigns] = useState([]);
  const [newCampaign, setNewCampaign] = useState({});

  useEffect(() => {
    axios.get('/api/campaigns')
     .then(response => {
        setCampaigns(response.data);
      })
     .catch(error => {
        console.error(error);
      });
  }, []);

  const handleCreateCampaign = () => {
    axios.post('/api/campaigns', newCampaign)
     .then(response => {
        setNewCampaign({}); // Reset the new campaign form
      })
     .catch(error => {
        console.error(error);
      });
  };

  return (
    <div>
      <h1>Email Campaigns</h1>
      <ul>
        {campaigns.map(campaign => (
          <li key={campaign.id}>
            <h2>{campaign.name}</h2>
            <p>{campaign.description}</p>
          </li>
        ))}
      </ul>
      <form onSubmit={handleCreateCampaign}>
        <input type="text" placeholder="Campaign Name" value={newCampaign.name} onChange={e => setNewCampaign({...newCampaign, name: e.target.value })} />
        <textarea placeholder="Campaign Description" value={newCampaign.description} onChange={e => setNewCampaign({...newCampaign, description: e.target.value })} />
        <button type="submit">Create Campaign</button>
      </form>
    </div>
  );
}

export default App;

// Back-end (Node.js and Express.js)
const express = require('express');
const app = express();
const mongoose = require('mongoose');

mongoose.connect('mongodb://localhost/promail', { useNewUrlParser: true, useUnifiedTopology: true });

const campaignSchema = new mongoose.Schema({
  name: String,
  description: String,
  emails: [{ type: mongoose.Schema.Types.ObjectId, ref: 'Email' }]
});

const Campaign = mongoose.model('Campaign', campaignSchema);

app.get('/api/campaigns', async (req, res) => {
  const campaigns = await Campaign.find().exec();
  res.json(campaigns);
});

app.post('/api/campaigns', async (req, res) => {
  const newCampaign = new Campaign(req.body);
  await newCampaign.save();
  res.json(newCampaign);
});

app.listen(3000, () => {
  console.log('Server started on port 3000');
});

Please note that this is a simplified example and the actual Promail source code is much more complex and robust.
