To avoid spam, we recommend using a “noreply” email address in Git repositories. However, Git contribution credit is based on having a Git email associated with your Github account. By default, the email address

username@users.noreply.github.com

is associated with your account. Be sure this email address is correct on each computer used to make Git commits, or you’ll miss out on Git contribution credit.

git config --get user.email

Correcting email in old Git push is possible via advanced Git operations.
