It would be great if secondary email addressed are automatically added to lists unless the donor/ admin doesn't want that to happen.

Right now, only the primary email address in the member profile gets emails from a manual or automatic list. That means we have to create another member profile with a different email address, just to send two members from the same household our weekly email newsletter.

It's confusing and if you have more than one admin, these additional member profiles can get deleted by mistake when someone is optimizing the database by deleting duplicate profiles that aren't caught by the merge duplicates feature.
