How Do I Set an Email Merge To a Small Company List?

I work in a small company (60 people) and use Apple Mail. I need to send emails to all employees and would like them addressed to each person individually (ex: Dear Joe) instead of sending them to our group list via BCC.
I keep the email address list in Excel and/or Pages.
Is there an Automator or Apple Script to recommend?
Is there a third party app?
(I saw a Q&A with Gary about this a few months ago, but there did not appear to be a solution.)
Thank you in advance.
