I have a few infrequently used Gmail accounts which forward on to another account which is regularly monitored.
When these infrequently used accounts receive emails and forward them on, I can get very similar looking emails which actually come from different addresses yet look at a very quick glance to be duplicates which is mildly annoying.
Is there any easy way to add a banner or prefix the subject line for example to say "this originated from..." or something along those lines?
I know there are banners which are added to emails identifying that the email originated outside a domain or a warning about containing viruses etc. but I'm guessing this is a feature of the local server so was wondering whether there was anything that could be done with Gmail.
