I have a question on Adobe sub domain configuration and one of the requirements is related to email masking i.e. e.g. If we delegate domain email.abc.co.nz but at the same time for some of the campaigns we would want to send few comms that shows email of relationship manager which means sender address shows firstname.lastname@example.org (parent domain) rather than email@example.com. Though this can be achieved by email masking but I have few questions to clarify:
Does Adobe supports email masking.
Is this recommended approach in terms of deliverability best practice and can have any deliverability impact?
Will this break any of the authentication for any ISP specifically DKIM?
Is there any doc around it showcasing the impact or recommendations.
