Custom Email Sender Domain

By default is the used email sender domain. If you want to use your own email sender domain, please follow the steps below to set it up.

Step 1. Define your email sender domain

First of all it is important to define your email sender domain. This can be your base domain, or a subdomain. In many cases, also due to security restrictions, projects completely brand the survey to its own needs.

Example: The survey is internally branded as IT Satisfaction Survey or ITSS. Therefore it is decided to have all emails send from

In the case of the example the defined email sender domain is:

Step 2. Configure your DNS for the sender domain

Once you have defined the email sender domain. This sender domain has to be configured within your environment. Contact your IT support team to help you with all the steps needed to execute this step.

For our systems to be able to successfully send e-mails on behalf of your domain, it is essential that our e-mailservers are given explicit permission to do so. Explicit permission is granted by adding a specific DNS entry for the chosen email sender domain. Share the DNS information below with your sys admins.

DNS Entry

Type: TXT Record

Name: survalyzer2._domainkey

Valuev=DKIM1; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDKyMtpfoipHUnOITQ8ZzsfQO/u5iuIVLblgQtnrlQMyPt5+oOhWteViqJZxo/5TC79Ir1MeQP8l/F/t1Nq6zCmU/8l7pBTGp1VrMV4rGOuLaoWNRHBDPVn2GRrutHp4ud8I7V19QoTkCffH6uY/Zcbtmte28LECmxj6Cxi2GJldwIDAQAB


In addition to this DNS entry, please bear in mind that since February 2024 Google and Yahoo require bulk senders to have DMARC in place. The following DNS entry needs to be configured for this

Type: TXT Record

Name: _dmarc.[] (e.g.

Value: v=DMARC1;p=none

Once the configuration is done, inform your project manager about the implementation.

Step 3: Preparing systems at Yorizon

From the moment we have received information about the set-up of the configuration, we will double check all the settings and have our systems prepared to be able to send e-mails on your behalf.

Final Step: Testing of the domain

All has been set-up and prepared. Now it is time for the final step of the process: the testing. Over the years we have developed a specific testing process, the bulkmail test, to check if the receiving end is ready to receive a high volume of e-mails from our e-mail servers.
