Really Basic

I just downloaded the mailer for access 2013, and I think im going to love this product.  I am wanting to insert fields from my access database into the message body.  I cannot find out how to do this.  But i have a table that has a renters id#, first name, last name, rent due.  All I'm trying to do is a sample email that would look like:

Dear John,

We noticed that you have not made your rent payment of $xxx.xx which is now past due.  Please make payment ....etc.......

I don't want to insert an attachment.  Thanks in advance.
