Setting Up a Domain Alias (CNAME)


A "CNAME"  (Canonical Name) is how we colloquially reference a domain alias. It allows an alternative domain name to be used to either access FocusVision hosted surveys or branded email sends. A CNAME can be created using a CNAME Record (for subdomains) or an A Record (for apex domains).

The setup presented here does not support secure connections and would only be used for accessing web pages over a nonsecure connection. To set up a secure connection, please reach out to your main FocusVision contact.

1: Setting Up a CNAME

You need a current domain to setup a CNAME. If you do not own a domain, you can purchase a domain from a third-party vendor such as Namecheap.

There are two ways to setup a CNAME:

CNAME Record - This is the easiest way to set up a CNAME. When a CNAME Record is set up, it redirects the current domain to the target domain and uses the same DNS settings as the target domain.

A Record - An A Record should be used when you can not set up a CNAME Record. For example, because your DNS system does not support CNAME Records, or because you are setting up an apex domain (domain.com) rather than a subdomain (customer.domain.com).

1.1: Using a CNAME Record

A CNAME Record should match the subdomain part of a current domain and its domain should point to the server where its surveys are hosted. To create a CNAME using a CNAME Record, add your CNAME Record as the host and your FocusVision server as the target.

For example, if you wanted to create a CNAME for customer, whose surveys are located on the main US server, the CNAME would be customer.domain.com and it would point to v2.decipherinc.com.

US Server


EMEA Server


APAC Server


1.2: Using an A Record

To set up an A Record, point your domain to the IP where your surveys are hosted. Please reach out to your main FocusVision contact in order to get the required server IP.

2: Sending Emails from a CNAME

If you plan on sending emails with your CNAME, you also need to set up MX, SPF, DKIM, and DMARC records. DKIM and DMARC are required for all email sends and need to be added manually, while MX and SPF will be automatically inherited in a CNAME Record setup.

Sending emails from an A Record CNAME requires additional setup, and guidance. Please reach out our support team or your main FocusVision contact if you need to send emails from an A Record CNAME.

DKIM and DMARC are both set up as CNAME Records. They should not be set up instead of the previous CNAME Record, and should not conflict with any CNAME Record that already exists, since it should be added onto a new subdomain setup.


To set up a DKIM, create an additional CNAME Record and add it to your subdomain.

For example, for customer.domain.com, you would need to set up main2016._domainkey.customer.domain.com and target main2016._domainkey.decipherinc.com.  

DKIM main2016._domainkey.decipherinc.com should be the same for all servers.


To set up DMARC, create an additional CNAME Record and add it to your subdomain. 

For example, for customer.domain.com, you would need to set up _dmarc.customer.domain.com and target _dmarc.decipherinc.com.

DMARC _dmarc.decipherinc.com should be the same for all servers.

Once you have setup both the DKIM and DMARC records, you will need to contact our support team to add the new CNAME to your mailqueue before you can begin using it.

3: Checking the Setup

3.1: Domain Tools

The easiest way to check the setup of your new CNAME is to use the "Lookup" option within the Decipher Domain Tools toolbox. Simply enter your CNAME, and press Enter to begin the check:

If SURVEY/SPF/MX/DKIM/DMARC are all highlighted green, then your CNAME has been set up properly and is able to send emails. If any of these fields are missing or in red, then you will need to review your setup.

Decipher Domain Tools was designed for internal testing, and is not customizable. Occasionally, the tool may not be able to pick up the DNS settings of your CNAME. In those cases, you can use a third party DNS lookup tool like MX Toolbox.

Verifying DKIM and SPF requires additional steps, which are outlined below.

3.2: Alternative Checking

3.2.1: DKIM Checking

For DKIM, your selector should be main2016 when checking. If you are using MX Toolbox’s DKIM Record Lookup Tool, the domain name would be your CNAME, and the selector would be main2016:

3.2.2: SPF Checking

SPF should be checked with the SPF Policy Tester Page. To check your SPF, enter one of the following FocusVision IP addresses under "IP Address":


Next, enter invite@cname_domain (example: invite@client.domain.com) under the sender address. If your SPF is configured correctly, a green "pass" displays at the end of the text:

If there are problems with the SPF configuration, a blue block may display at the end of the text instead:

In this case, your SPF has been configured incorrectly and your setup will need to be reviewed.

3.2.3: MX and DMARC

To check your MX and DMARC, simply enter your domain name in the MXtoolbox. The MX lookup can be found here and the DMARC lookup can be found here.

4: Enabling the CNAME

After verifying your CNAME configuration, send the CNAME to your main FocusVision contact or support team to add it to your company page.

Once your CNAME has been added to your company, you can use it for masking survey URLs. To mask a survey URL for a project, add the specific CNAME to the CNAME field in the "Field Settings" window and click "Save":
