It's probably a good idea to set up two-factor authentication and add an 
app-specific password for "git send-email" (at least that's what I do).

The password can be stored encrypted using the OS keychain, or if you
don't want/have one (e.g. you are running headless) you could check if
your distro installs git-credential-netrc.  Create a ~/.netrc.gpg file,
where the decrypted content should look like

    machine smtp.gmail.com login larsxschneider@gmail.com password mypassword

Then do

    git config --global credential.helper netrc

and you're all set. :)
