Never accidentally send emails to real people from your staging environment.
Send all staging emails to a group email address without accidentally emailing users with active email addresses in the database.
From the command line:
heroku config:add EMAIL_RECIPIENTS="firstname.lastname@example.org" --remote staging
Optionally prefix the subject line:
Mail.register_interceptor RecipientInterceptor.new( ENV['EMAIL_RECIPIENTS'], subject_prefix: '[STAGING]' )
