"Who could have imagined this? As we noted a week ago, the Trump camp's massive fundraising blitz ending up hitting legislators in numerous foreign countries as well as spamming a seemingly limitless number of victims around the world. According to ReturnPath, 79% of Trump fundraising emails were caught in spam filters, an extremely high rate by industry standards, seemingly because Trump was using purchased or rented lists rather than ones the campaign had grown organically through campaign-related supporter sign ups. In any case, this led to problems. At least one of the bulk email platforms Trump's campaign was using to send between 50 and 60 million emails moved rapidly to suspend his access because the "email in question has raised serious security and legal concerns among Adestra and other industry leaders"."
