Integrating MS Excel and MS Outlook

I'm an office assistant and I send out a lot of emails to all the other employees in the office. Most of the time I send out official communications what are on an Excel file; then customize it and send it to everyone. It's very troublesome editing each template then sending it especially if there's a considerable number of people in the company.
Is it possible to have a macro created so that I can just push a button, then everything will be filled in and the email will automatically be sent through Outlook?
