We are working to scale our digital marketing efforts at my company, building more campaigns, emails, landing pages, forms, etc. We have worked to developed a strong email 2.0 template as well as a pretty flexible landing page template with a 3rd party design team. Our internal creative services team wants to get more involved, working directly within our instance. We have talked about utilizing a sandbox environment for the design team to tinker, test and iterate, and we are still unsure if this will create efficiencies or just more work for our marketing ops team. Our design team lacks HTML experience, really would be designing in Design Studio instead of In-Design.
I'd love to hear from you how you are handling this at your companies.
