Test email on localhost

My application is sending emails (from a few specific functions in my controllers).
To generate the email, I use a set of views (template with header, main_content and footer), and I pass a $data array to it.
How can I be sure the emails are correct, BEFORE I publish my website online?
Is there a way to test this? If so, which settings do I have to use?

Test Mail Server Tool

You will need to setup your php.ini file to use smtp mail protocol.

I use my hosting providers ( Comcast )

What did you Try? What did you Get? What did you Expect?
