Sending mail message to multiple contacts

macOS & Mac Apps

Hi everyone,

I want to send a mail message to multiple recipients. However, I want to select the recipients by going through my list of contacts and selecting the people to whom I wish to send the message rather than typing in their names. So this is what I'm doing:

1. creating a new message;
2. Using Vo-Space on the BCC button.
3. My list of contacts appears. However, no matter what I do, I can't seem to select them to add them to my list of recipients.

Thanks a lot for any help with this one, I know I'm doing something daft.
