How to connect your IONOS domain to systeme.io

In this guide, you will learn how to add DNS records in IONOS to connect your root domain. This allows you to use your custom domain (e.g., www.domain.com) for your sales funnels and blogs, establishing a professional brand presence.

What you will need:

A systeme.io account
A domain name purchased from IONOS

Important: Please follow the first step of this article before proceeding with this guide.

After adding the root domain to systeme.io, you must access the DNS settings in your IONOS account.

Note: Each domain added to systeme.io has unique CNAME records that must be added to your host's DNS settings.

Example:

In this example, we will connect the domain www.sio-demo.com to systeme.io

First, hover over your profile picture, click Settings, then go to Custom Domains and add your custom domain.

First CNAME:

Go to the DNS zone for your domain name, then click on Add a record.

Select the CNAME type.

Enter www in the Hostname field, then enter dsq5ytes5ap90.cloudfront.net. in the Points to field.
Finally, click Save.

Note: If a CNAME record with the name www exists, edit the target to dsq5ytes5ap90.cloudfront.net.

Second CNAME:

Go to the DNS records for your domain.
Click Add a record and select CNAME as the type.
In the Hostname field, enter only the part of the text that appears before your domain name (in our example,_be50f0c6ab135efbaccc95c5129852f6).
Then, enter _04afcedac82192a5587b6ea2c6045981.zfyfvmchrl.acm-validations.aws. in the Points to field.
Finally, click on Save.

Once the two CNAMEs are correctly added to your host, you can check their status using the following tool: https://dnschecker.org

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 check your DNS zone:

CNAME verification 02:

Add a redirect rule:

Log in to IONOS and go to the Domains & SSL section. Select your domain, which in our example is sio-demo.com. Then click on the button Change the type of use.

On the next page, you will see a list of options. Click on Redirect domain.

In the Redirection destination field, enter the URL you want to redirect to. (e.g. www.sio-demo.com).
Check the box for Also configure for www subdomain if you want to include subdomains.
Select HTTP Redirection (Recommended): This option changes the URL displayed in the address bar.
Finally, click Save to confirm the redirection.

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 this occurs, contact your host support to determine if those existing records are necessary or if they can be safely deleted.
