Sender Authentication

During the launch process with Cerkl, you will work with our Customer Success team to set up Sender Authentication, a provision that shows email providers that Cerkl has your company's permission to send emails on behalf of your custom email domain. This is helpful for dealing with spam filtering and verifies that communications via Cerkl are coming from a trusted source, as it completes the "mask" that allows emails to come legitimately from your company's domain as opposed to appearing as if the email was spoofed.

In order to make this work, we will need you to set up 5 CNAME records on your company's domain name server (DNS). You will do this during the implementation portion of your launch with Cerkl facilitated by your Customer Success Account Manager. Once you have completed the CNAME record attachment, you will then need to reach out to your Account Manager or Platform Configuration Engineer so that they can verify everything is working properly.

Additionally, setting up a Reverse DNS will effectively associate your Dedicated IP with your organization. This is accomplished via adding an A Record to the DNS for your company's domain.

CNAME Records

CNAME records (canonical name records) alias your company's domains and subdomains, pointing them to our email provider in order to sign messages with validation, sand they they will be visible to your email recipients. This helps to make sure we can route all of your communications properly and securely.
