1. Open Git Bash.

2. Change the current working directory to the local repository in which you want to set your Git config email.

3. Set your email address with the following command:

git config user.email "[email protected]"

4. Confirm that you have set your email address correctly with the following command.

git config user.email

Globally set email-address (only used when nothing is set locally)

1. Open Git Bash.

2. Set your email address with the following command:

git config --global user.email "[email protected]"

3. Confirm that you have set your email address:

git config --global user.email

Or using environment variables

1. [email protected]
2. [email protected]

PD: Info from github official guide

According to the git documentation, all you should have to do is re-run

$ git config --global user.name "John Doe"  
$ git config --global user.email [email protected]  

Then just check to make sure the change took effect

$ git config --list
