How to connect your Cloudflare subdomain to systeme.io
What you will need:
- A systeme.io account
- A domain managed by Cloudflare
Important: Please follow the first step of this article before following the instructions on this page.
After adding the subdomain in systeme.io, you need to see the DNS settings in your Cloudflare account
Note: Each subdomain added to systeme.io has its own CNAME records to integrate into the hosting site.
Example:
In this example, we will connect the subdomain example.test-sio.org to systeme.io
You will then need to log in to your systeme.io account and click on your profile picture, then go to Custom Domains and add your subdomain.

First CNAME:
- Go to DNS, then click on the Records tab of your domain name.
- Click on Add record >>Select the type CNAME >> Enter example in the Name field >> then add dv5xmtsih8vdv.cloudfront.net. in the Target field >>set the Proxy status to DNS only, then click Save.

Note: If a CNAME record with the name example already exists, edit its value to dv5xmtsih8vdv.cloudfront.net.
Second CNAME:
- Follow the same process described above to add a new CNAME record
- In the Name field, copy and paste the string before your domain name, which in our example is _1e366b448745f61ccc649902693d7606.example >> In the Target field, add _c70c6d7febc99dd01828cb70f1c6b5c6.xlfgrmvvlj.acm-validations.aws. >> Set the Proxy status to DNS only and click Save.

After adding both CNAME records, you can verify their status using this tool:
You should see the same value you added next to a green checkmark, as displayed in the example below. If not, the records have not been added correctly, and you need to review your DNS zone:
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 you encounter a conflict, contact Cloudflare support to determine if those existing records are required or if they can be safely deleted to allow your subdomain to connect.
