Right now, we don't have good data on which devices donors use to donate via email. For banner donations, we use substr(utm_campaign, 12, 3) , which is IPD/MOB/DSK as targeted by CentralNotice. On donatewiki, via javascript or the FundraiserLandingPage extensions, can we add those strings to utm_campaign when utm_medium is email?
@CCogdill_WMF , would this be useful or make things worse for you? @Pcoombe , would it be straightforward to do this in JS, or do you think the PHP extension would make more sense?
