In order to authorise Marketo to send emails on your domain’s behalf and prevent your emails from being blocked or sent to spam you will have to add Marketo to your SPF record if you already have one.

The SPF entry that you need to add to your current SPF record before the “all” mechanism is::

include:mktomail.com

If you do not have an SPF record and this is the only email service sending on your behalf then your SPF record will look like this:

[yourdomain.com] IN TXT v=spf1 include:mktomail.com ~all

For more information on how to configure SPF with Marketo please click on the button below.

By default Marketo uses a shared DKIM signature to sign your emails. However, if you would like to use your custom domain in the From address of your emails and custom sign them with DKIM you will have to create a DNS record that Marketo will provide you with.

Once the DNS record has been created and the change has propagated across the internet you will have to go back to Marketo and verify the DNS record.
