Parche en formato de cadena de correo: ¿cómo?

I am developing a tool with 3 others. We usually communicate via patches in git. This is how we do: 1. A makes changes, creates patch using format-patch, attaches it to mail(outlook) and send. 2. B and C download, place at x location and apply using am.

Mis preguntas son las siguientes:

1. Are we doing anything wrong? (coz we have to explicitly attach patch to outlook and download)
2. Is there a tool or a way that I can see the patches to and fro in así format? So that I have the whole patch Conversation at once from git itself so that I don't need to look into outlook for conv history.
