Automate Emails

I have a list of emails and contact person for each email. The email body, content is the same.
So I want to address the correct person, like Dear X/Y/Z respectively for each email. How to handle such work?
I don’t want to copy/paste each time by changing the name of addresse (dear xyz) each time. Any better method?

You need to know some programming. Maybe there is some automated email program that can help you.
