In setting up our instance to ensure email deliverability, we are looking into using an email subdomain, such as email.example.com, for outbound emails from Marketo. Is this a critical step in setting up a successful Marketo instance?
If so, what are the best practices for using a new email subdomain as the "From address"? Should we create a central email address on that subdomain, like email@example.com? Or should we create a number of emails, such as firstname.lastname@example.org?
Any further documentation outside of the Setup Outline would be appreciated, as we use Google for our email and I noticed it mentions needing an abuse@ and postmaster@ email in order for an email domain to work in Marketo, which seems to require extra steps for Google users.
