As we saw in the previous examples, git format-patch creates the patch files in the Unix mbox format, so only a little extra effort is required to allow Git to send the patch as an email. When sending emails with git send-email, make sure your Mail User Agent (MUA) does not break the lines in the patch files, replace tabs with spaces, and so on. You can test this easily by sending a patch to yourself and checking whether it can be applied cleanly to your repository.
