We attach hundreds of emails to cards a day. Each email could have 20 small logos in the signature. Some email chains have multiple signatures. Some cards have over 300 facebook and twitter logos as attachments that have to be deleted one at a time. It clogs up the cards, makes finding important attachments more difficult, and wastes hours of time deleting unneeded attachments. We have tried telling all users to delete signatures before forwarding but this is also time consuming on lengthy emails, so most don't.
