Notes on Capabilities

DMARC: DMARC compliance through SPF and DKIM.

DKIM: Email sent via Marketo can be made DMARC compliant by configuring DKIM:

SPF: Marketo's documentation describes how to setup SPF, but Marketo always uses their own domains in the bounce address unless you contact support and arrange to white label the return-path address. Marketo support provides additional information to set SPF correctly.


When deploying DMARC, domain owners often find new sources of email.

Domain owners then wonder if the source is capable of sending DMARC compliant email.
