What is the proper salutation of multiple clients?

The proper salutation for multiple clients typically starts with "Dear Clients," or "Dear Valued Clients," to acknowledge the group respectfully. If you know their specific names, you can also use "Dear [Client Name 1], [Client Name 2], and [Client Name 3]," but this is more personal and may be less practical for larger groups. Always ensure the tone is professional and appropriate for the context.
