 Transcript

To be able to start sending emails or publish landing pages with Adobe Campaign, you need to set up a new subdomain. Adobe recommends to fully delegate your subdomains to Adobe Campaign, and to only use CNAMEs if you must, for security reasons.

In this video, I will show you how to set up and submit a subdomain using CNAMEs in the control panel. This is a three-step process. First, you will need to set up the new subdomain in the control panel. You will then need to create the DNS records in your domain hosting solution.

And once the DNS records have been created, you will need to submit those domains in the control panel.

Let’s get started. Navigate to the control panel, then click on subdomains and certificates.

Select the instance you would like to set up new subdomains for. You can only set up subdomains for production instances. And as you can see here, all other instances will be grayed out.

Click on the setup new subdomain button and select CNAME.

Click next.

If you selected the Campaign Classic instance, you will need to select your use case for this instance, either marketing communications or transactional and operational communications. The instance I selected is a campaign standard instance. So by default, the use case is marketing communications. Click next, fill in the full name of the subdomain you would like to submit. The system will verify if the sub domain has not already been delegated. Once it is verified, click next. In this step, control panel generates the record that are required DNS entries for the correct functioning of the requested subdomain. These records need to be created in your DNS hosting solution. The list of records include domain name entry for the tracking domain, resource domain, mirror domain, and others such as domain key authentication and records for forward domain resolution.

You can either download these in a CSV file. For example, if you need to send it to the administrator of your hosting solution, or you can copy each of the records manually.

For example, if you have direct access to your hosting solution and would like to set up the DNS records now. Once you have downloaded the CSV, or you have copied the records, click next.

If you have already created the DNS records at this point, you can submit the subdomain. If you cannot create the records yourself, or need to do this at a later point, you can select submit later. In that case, all the information that has been generated up to now will be stored in the control panel for 30 days. And you can submit the subdomain, once the DNS have been created in your hosting domain. I will select this option.

A pre-processing card is now available at the top of the screen. And you can access the wizard and submit at any time within the 30 days, by clicking the review to submit button. Now, let me show you what happens when you submit without having the DNS records configured. I will quickly create a new subdomain for this purpose.

Now you can see that the system, when I submit, checks if the records are available. And in this case as I haven’t created them yet, it will give you a warning. You can still save and submit later. And the preprocessing card, in this case, will show that the DNS records are missing.

In the next step, I will need to create the DNS records in my hosting solution. I will do this for my first domain. I have all the data in the CSV file available, and I will now need to create five records for the subdomain.

I will copy and paste the name, select the record type CNAME, then copy and paste the value.

And as for the TTL value, since it impacts how soon updates to DNS records reflect in the real world, we recommend TTLs in a lower range. The value you see here as the default value. And I will just leave it for this demo.

Now that all five records have been created, I can submit my subdomain in the control panel. So I’ll go back to the control panel, and click on the review to submit button.

And then I will submit my subdomain now.

To see the status of the configuration process, you can click on the detailed view. At this point, also, please reach out to your deliverability consultant or to client care, to let them know you’ve submitted a new sending domain via the control panel and that you’d like to work with someone in deliverability to finalize the IP segmentation strategy for it.

Once the configuration process has been completed, you will be able to see the details of your subdomain by clicking on sub domain details. Here, you will see all the elements that have been created such as, the sub domain with the DNS records, A, MX, CNAMEs, DKIM, SPF and TX, additional sub domains to host mirror pages, trackings, and so on. Thank you for watching. -
