You have an error in your template path that cause wrong path to template when the module is installed in the sites/all/module/ folder.
The correct way is to use drupal_get_path('module', 'mailup') to get the path where the module is installed.
There is another little naming issue: your module's name is "mailup_integration" so the .module file should have the same name (actually it is mailup.module).
BTW I attach a patch that work with the current naming.
