Our agency is working with some clients that use DTM. As part of our work, we're going to embed a marketing script on their pages. We'd love to embed using DTM, but would want to test ahead of time to ensure no conflicts. Is there a place to get developer access to a DTM sandbox or would we have to pay for the whole marketing cloud?
