Same newsletter create multiple feeds

Follow up, I think this is the problem that was happening with me. This is one of the recipients: prvs=0692e951df=788350019346285_1931@bounces.marketing.gedidigital.it As far as I’ve seen the mails are in the form prvs=’random prefix’=788350019’random suffix 1’_’random suffix 2’ @bounces.marketing.gedidigital.it 788350019 is always present, probably is the newsletter ID Is there anything that could be done here to merge these newsletters? Maybe one thing that could be interesting for Newsblur is to be able to manually merge feeds, maybe with custom rules, in case some of this happens Edit: t
