Updated over a week ago

This article covers the SPF and DKIM authentication processes for Email Blaster and how they are managed in Valimail. While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.

Email Blaster uses the new 2048-bit key length for added security and is recommended by service providers such as Google.

The DKIM record sits behind the scenes on your company domain name, it is placed on your DNS server (like an SPF record).

On your organization DNS server, create a CNAME record with the following values:



Remember to replace with your actual domain name!

This CNAME record forwards the verification check onto the email blaster network, which your subscribers email server will then be automatically provided with a secure key to verify the authenticity of your email.

NOTE: If you manage you domain in Valimail, you will need to add the CNAME DKIM key on your domain's configuration page in the Valimail platform.
