Answer:
The right person to DM about marketing proposals depends on the specific proposal and the company or organization that it is intended for. Generally, it is best to contact the marketing department or the person in charge of marketing decisions at the company or organization in question. This person or department will be able to provide the best advice and guidance on how to proceed with the proposal and whether it is a good fit for the company or organization. Additionally, they may also be able to provide helpful resources or contacts to make the proposal process easier.
