Can we get a training video made up around get response's new requirements affecting email deliverability regarding a customer domain email for gmail and yahoo users that needs to be authenticated with DKIM and the adding of a DMARC policy. A video training and insight on this would be most helpful to the newbies and beginners like myself to avoid what I can see as a major road block and point of getting stuck and frustrated to many when this happens in February of this year.
