This allows you to add a subdomain (subdomain.domain.com) to systeme.io for use in your sales funnels and blogs, helping you maintain a professional brand.
What you will need:
Important: Please follow the first step of this article before following the instructions on this page.
After adding the subdomain in systeme.io, you will need to access the DNS settings in your Namecheap account.
Note: Each subdomain added to systeme.io has its own CNAME records to integrate into Namecheap.
Example:
In this example, we will connect the subdomain example.sio-team.org to systeme.io
First, hover over your profile picture, click Settings, then go to Custom Domains and add your subdomain.

First CNAME:


Note: if a CNAME record with the name example already exists, edit its value to d1wzk10427sdbr.cloudfront.net.
Second CNAME:

Note: To check your records, you must enter the full CNAME name (including your domain name) into the search bar.
CNAME 1 verification:

CNAME 2 verification:

Notes:
- It can take up to 24–48 hours for DNS records to propagate completely.
- Sometimes, your host may not be able to register a CNAME record due to a conflict with other existing DNS records. This usually happens when adding the first CNAME. If a conflict occurs, contact your domain host's support team to determine if the existing records are necessary or if they can be safely removed.
