How to Set Up DKIM for Adobe Marketo?

Enabling DKIM signing for your domains can help you keep your email content intact throughout the delivery process, barring threat actors from accessing and altering your emails. This helps preserve your identity and eradicate spam and phishing attacks. 

Set up a Custom DKIM Signature

In order to ensure top-notch deliverability, we automatically sign all outbound mail with a shared Marketo DKIM signature. You can personalize the DKIM signature to reflect the domain(s) of your choice. Here’s how.

1. Go to the Admin section.

2. Click Email, then the DKIM tab, and finally Add Domain.

3. Enter the domain you will be using in Marketo emails as the From Address and click Add.

4. Send the Host Record and TXT Value to your IT. Ask them to create the record for you and make sure it propagates to all nameservers associated with the from domain. Marketo’s DKIM verification requires that the DKIM key is propagated to all nameservers associated with the domain being DKIM-signed.

5. Once they confirm they’ve created the record, come back to Marketo, select your domain, and click Check DNS.

Note: If the confirmation fails and your IT has created the record correctly, it may be a matter of DNS propagation. Try again later.

Caution: Modifying/removing the corresponding DNS record will result in harmed deliverability. Make sure to delete the entry in Marketo before making DNS changes.
