Email a Client lets us whip off a quick email to a Client without making a huge Event or campaign about it.
Options
To hide each eMail recipient’s email address from one another you can drag and drop the email addresses from the eMail’s To: field into the BCC: (Blind Carbon Copy) field. This way everyone still gets the eMail but cannot view all the other addresses.
You can still add an eMail Event Action later for the Marked Clients.
