This update includes two smaller but nice-to-have features:
Client Names Separate from the Primary Contact Name
Sometimes a client is not a person, so now you can give the client a name separate from the primary contact. The client name (as opposed to the primary contact’s name) will now be shown throughout Client Power Tools.

You don’t have to give clients a client name; if you don’t the primary contact’s name will be used.
Additional Contacts
Often the primary contact might not be the only person who should receive messages, so now you can add additional contacts to each client who will receive CCs. When sending a message you can remove any of those CCs.

To help you keep track of who got what, when, recipients will be saved with the message and displayed in the message list.
