Define the content the composer can carry
Begin with a representative newsletter and identify the blocks staff actually needs: an image, an announcement, a call to action or another approved component. Agree how each block is stored and what the receiving editor supports. Decide how an unsupported layout is explained before transfer. A defined content contract gives the designer, saved draft and host preview a shared basis for review. Keep the first supported set small enough to exercise with actual approved announcements, links and image examples.
