PTR records

About PTR records

A pointer record (PTR) is a type of Domain Name System (DNS) record that provides the domain name linked to an IP address.

With PTR records, receiving mail servers can check the authenticity of sending mail servers by identifying whether their IP addresses correspond to the names with which the servers connect.

Access your subdomains’ PTR records

Once a subdomain is delegated in Adobe Journey Optimizer, a PTR record is automatically created and associated with this subdomain. You can access it from the Channels > Email configuration > PTR records menu.

The list shows the PTR records generated for each delegated subdomain, using the syntax below:

  • “r” for record,
  • “xx” for the two last figures of the IP address,
  • subdomain name.

You can open a PTR record from the list to display the associated subdomain name and IP address.

Edit a PTR record

You can modify a PTR record to edit the subdomain associated with an IP address.


You cannot modify a PTR record associated with a subdomain that was delegated to Adobe using the CNAME method.

  1. From the list, click a PTR record name to open it.

  2. Edit the subdomain as desired.


    You cannot modify the IP and PTR record fields.

  3. Click Save to confirm your changes.

An Updating icon displays next to the name of the PTR record in the list.

To check the PTR record update details, click the Updating or Recent updates icon.

You can see information such as the update status, and the requested changes.

Update statuses

A PTR record update can have the following statuses:

  • Processing: The PTR record update has been submitted and is going through a verification process.
  • Success: The updated PTR record has been verified and the new subdomain is now associated with the IP address.
  • Failed: One or several checks have failed during the PTR record update verification.


Several deliverability checks will be performed to verify that the new subdomain to associate with the IP address is valid.


You cannot modify a PTR record while update is in progress. You can still click its name, but the Subdomain field is greyed out. The changes will not be reflected until the update is successful.

During the validation process, the old subdomain is still associated with the IP address.


Once the validation process is successful, the new subdomain is automatically associated with the IP address.


If the validation process fails, the older PTR record is displayed. The valid subdomain that was previously associated with the IP address remains unchanged.

The possible update error types are as follows:

  • Failure to create a new forward DNS for the PTR record
  • Failure to update the record
  • Failure to re-onboard the affinities

Upon update failing, the PTR record becomes editable again. You can click its name and update the subdomain again.
