python - In Django, is it better to add admin features to the command line or the admin interface? -

in specific case, i'm building relatively straightforward email-sending webapp. i'll need add ability human generate email templates last day's worth of updated objects, view day's last sent emails, etc.

django provides django manage.py cli, , django admin web ui. both augmentable. there best-practices or rules of thumb follow in terms of adding email admin functionality 1 or other?

edit: more clear, big concern around speed of implementation operations on models , such.

i sugest stick web interface if used human. cli when want control application app or sort of script.

many people have problem using cli. remember potential client 'less technical' person you, ui should user friendly him.
