Addon domains allow you to host multiple websites with a single hosting account. Each addon domain looks and works like a completely separate website, even though it uses the same hosting plan.

This guide explains what addon domains are, how they work, and how you can set them up step by step.


What Is an Addon Domain?

An addon domain is a fully functional domain that you can add to your hosting account. After setup, the addon domain works like a standalone website with its own:

  • Website files

  • Email accounts

  • Subdomains

Unlike subdomains (like blog.yourmaindomain.com), addon domains have their own unique domain names (like yournewsite.com), but share space in the same hosting plan.


Why Use Addon Domains?

Here are the main benefits of addon domains:

✔ Host multiple websites using one hosting plan
✔ Manage all sites from the same control panel
✔ Save money compared to buying separate hosting for each site
✔ Separate content and emails for each domain

Addon domains are perfect if you want to start more than one site without paying for multiple hosting accounts.


Before You Start

Make sure you have the following ready:

✔ You Own the Domain

The addon domain must already be registered with a domain registrar.

✔ Nameservers Are Updated

Make sure the domain’s nameservers point to your hosting provider’s servers. If not, update them and wait for propagation.

✔ DNS Propagation May Take Time

After updating nameservers, changes may take up to 24–48 hours to spread worldwide.


How to Add an Addon Domain (Step by Step)

Follow these steps to add an addon domain to your hosting account:


Step 1: Log in to Your Control Panel

Sign in to your hosting control panel using your account credentials.


Step 2: Navigate to the Addon Domain Section

Look for the Addon Domains tool under the Domains section in your control panel.


Step 3: Enter the Domain Details

You’ll see a form asking for:

  • New Domain Name – Enter your addon domain (e.g., yournewsite.com)

  • Subdomain/FTP Username – Automatically filled, but you can change it

  • Document Root – The folder where the site’s files will be stored

Make sure the document root folder is unique for this addon domain.


Step 4: Click “Add Domain”

Once you fill in the details, click the Add Domain or Create button.

Your new addon domain will be created, and a folder will be added to your hosting file structure.


Upload Website Files

After creating the addon domain:

  1. Go to File Manager or connect via FTP

  2. Open the addon domain’s root folder

  3. Upload your website files there

Now the addon domain is ready to host its own website content.


Install Applications (e.g., WordPress)

You can install WordPress or other applications on your addon domain just like a primary domain:

  • Use your one-click installer

  • Choose the addon domain from the installation dropdown

  • Complete the setup

Each addon domain works independently.


Create Email Accounts for the Addon Domain

You can create separate email accounts for your addon domain:

Example:

[email protected]
[email protected]

Go to the Email Accounts section in your control panel and choose the addon domain when creating new addresses.


Common Issues & How to Fix Them

Here are some common problems you might face and how to solve them:

❌ Domain Not Working After Setup

✔ Make sure nameservers are correct

✔ Wait for DNS propagation (up to 48 hours)


❌ Uploaded Files Not Showing

✔ Check that files are in the correct addon domain folder

✔ Ensure you have an index file (index.html or index.php)


❌ Email Not Working

✔ Verify MX records are set correctly

✔ Make sure your email account is created for the addon domain


Tips for Managing Addon Domains

✔ Use clear folder names to avoid confusion

✔ Regularly update site files and applications

✔ Set up backups for each domain

✔ Monitor site speed and performance

Addon domains give you flexibility, but proper organization helps keep everything smooth.
