If you already have a domain name, Sarbacane provides you with a delegation configuration option, meaning that you will be able to create a subdomain. The advantage of this option is that you can benefit from the already existing reputation of your domain.
In the “settings” section of Campaigns, go to “Domains”, then click on “add a domain name”. You can then choose the “existing domain” option:

You will then need to go to your domain name host to create this link.
The configuration example below is based on the OVH host interface, but all hosts operate in more or less the same way.
Nota bene: further down in the article you will find the hosts that do or do not allow this type of delegation, as well as redirect links to their help center for implementation.
Once you have retrieved the records provided by Sarbacane in your interface (see the implementation article), you will be able to apply them with your hosting provider.
Go to the DNS zone of your domain.
There you will find an option to add an entry.

Let us start with the TXT.
Here is the type of display at the time of adding it.

The TXT record must be entered on your root domain, here sarbacane.ovh (and not the subdomain you have just created on Sarbacane). You should therefore see only your domain appear as shown below.
Enter in “Value” the entry provided in your account (the string of characters ending with the equals sign).

Then confirm the addition.

Let us continue with the NS records.
Adding the NS records is done in the same way; modify the field type by choosing NS this time.
Enter the subdomain defined in step 1 on Sarbacane (here test). Then add in the target the first value indicated in the third step on Sarbacane.

Perform the same action for the second NS record provided in the last step on your account.
The validation time in the application may vary between 24 and 48 hours (this depends on your hosting provider).
If your subdomain is not validated, contact support via chat.
Some hosting providers allow you to add NS records directly in the DNS zone in order to set up a delegation, while others do not. Here is the list:
