There are situations that require to hide addresses in Outlook from recipients, such as performing a large mailing. If you are composing some type of personalized business correspondence, for instance, hiding recipients in Outlook will allow for a more delicate, proficient and effective approach.
Let us imagine that one has to send reminders each month to all staff members: each staff member will receive a letter with the reminder text in this case, but each recipient will be able to see a lot of unrelated email addresses, and some recipients may even be uncomfortable with their email addresses visible to others, not counting the fact that an obviously automated and impersonal email message receives less attention than a personalized one. With this in mind, a personalized letter with hidden list of recipients is less likely to be ignored by its addressee and is, generally, a more appealing and professional way of reaching out to the staff members or clients.
