To allow Cyber Guru to send emails (for example, release communications via Student Caring) on your behalf in a secure and industry-compliant manner, you need to configure a dedicated subdomain on your main domain.
This configuration allows you to:
Ensure that sent messages appear authentic and verifiable.
Prevent emails from ending up in the recipients' spam folder.
Main requirement: dedicated subdomain
For secure email sending, it is required that you provide a dedicated subdomain, to be reserved exclusively for communications sent via Cyber Guru.
Example:
securityawareness.clientdomain.com
The sender address ("From") will be an email belonging to this subdomain, such as:
support@securityawareness.clientdomain.com
Why a dedicated subdomain is necessary
Using a dedicated subdomain represents the industry standard for securely delegating email sending. The main advantages include:
✅ Your main domain is never exposed or compromised.
✅ Authentication standards (SPF, DKIM, DMARC) can be managed independently.
-
✅ Any reputation issues related to sending do not impact your main business domain.
Activities required from you
To complete the configuration and allow Cyber Guru to send emails on your behalf, we ask you to perform the following activities:
1. Subdomain creation
Create a dedicated subdomain on your main domain and communicate it to Cyber Guru.
Example: securityawareness.clientdomain.com
2. Publishing DNS records
Cyber Guru will provide a set of DNS records to publish (mainly 6 CNAME records and 1 TXT DMARC record).
You will need to add them exactly as indicated in the communication you receive from the Cyber Guru team.
3. Definition of email sender
Specify an email address belonging to the subdomain to be used as the official sender for communications sent by Cyber Guru.
Communicate the sender to Cyber Guru.
Example: support@securityawareness.clientdomain.com
Once the configuration is complete:
Emails sent by Cyber Guru on your behalf will be secure, authenticated, and recognized as legitimate by major email providers.
The entire configuration will comply with international security and deliverability standards (SPF, DKIM, DMARC).
4. Verification and joint testing
Once the configuration is complete, Cyber Guru and you will perform a series of verification tests together to confirm that
Emails sent by Cyber Guru appear authenticated via SPF, DKIM, and DMARC.
Messages correctly reach recipients' mailboxes without being flagged as spam.
Only after successful joint testing will the configuration be considered active and fully operational.
