Continuing on from our earlier work of sending less but better mail and making it faster to import i18n translation templates: Launchpad will no longer send mail when it successfully imports a template. You can see in the web ui when the template was last imported, and you will still get mail if there’s a problem.
I could hardly put it better than Riddell:
Danilo asked for my reasoning. My reasoning is that pointless e-mails are a pain.
(I hope we’ll eventually have a more structured notification model, that will let you choose to see some notifications by mail and others in the web ui. One step at a time.)
