Sending a group email
I would like to send an email using Apple Mail to a group of about 75 people. Most of them are not in my Contacts, and I do not want to add them. I have the emails in an Excel spreadsheet, so I am confident I can create a text file with the addresses from that.
What is the best way to do this.
Thank you.
