Process or Workflow for a virtual Introduction email

I am interested in a process that will allow me to auto populate a contact information into a new email.  It will be what I call a Virtural Introduction Email.  I can't find any process like this anywhere so I thought I would start here.

I am not sure if I create a Business Process Flow or a Workflow. My objective is

1. Create a new email 
   
   • I will use an email template the I have already created called "virtual introduction"  the email has fields for my contact person that I will be providing to my email recipient
2. Provide the contact information that I want to auto populate the fields in the email

How can i accomplish these two tasks in a workflow or process?
