Great tip! As an alternative, if you're uncomfortable rewriting all of a project's history using git-filter-branch, Git has a feature known as mailmaps which allow you to canonicalize username and e-mail addresses.

Here's an example of how to fix the email address of commits.
Don't rewrite all commit authors, only the commits with the incorrect email address.

     GIT_AUTHOR_EMAIL=michael@example.com
   fi
 ' HEAD

Thank you for this post. I had the exact same situation. In my case, most of the commits were under my work email.

Sweet and concise post, thanks a lot. This is a problem I have run into way more than I would like to admit 🙈
