Setting up the cname for a second tracking link

[Eben_Shapiro]

I'd like to set up a second tracking domain. There doesn't seem to be specific instructions for what the cname should look like for this. All I could find are the instructions for setting up the default tracking link:

Configure Protocols for Marketo - Marketo Docs - Product Docs

My question is, if my default tracking domain's cname looked like this:

pages.abc.com IN CNAME mkto-a0244.com

Then could the cname for the second tracking domain look like this?:

pages.xyz.com IN CNAME pages.abc.com

Thank you,

Eben

Hi Jim, I'm not sure if this applies. Looks like this is for Landing pages and not Email Tracking links. It looks like those two things have different instructions for setting up the cname.

Yes, you can do it that way, but I would bypass the original domain and create another CNAME to mkto-*.com. Bouncing off the first CNAME is extra DNS traffic and means the 2nd domain depends on the 1st -- no real upside.

Thank you Sanford. That's a good idea about not chaining the cname.
