Understanding relation between CNAME, SPF and DKIM settings

[Anonymous]

What is the purpose of the CNAME setting and how important is it for this field to be showing up with correct domain name if SPF and DKIM settings are already verified and showing the desired URL?

There is not any direct relationship between DKIM + SPF records, which are used for signing and authenticating outbound email, and the CNAME records you create so people can visit your landing pages and register clicks with the branding (click tracking) server.

If CNAMEs are not set up correctly, then even if the email reaches someone's inbox, the links in the email will not work.  If DKIM is not set up correctly (especially in the case of a bad signature), mail will not be delivered, which is obviously also bad. So they are not related to each other, yet they are both critically related to marketing effectiveness.
