Google’s Gmail cost Republican candidates over $2 billion in contributions since 2019 by flagging most fundraising emails as spam, according to research shared exclusively with Fox News Digital by the Republican National Committee, National Republican Congressional Committee, National Republican Senate Committee. The Republicans based their conclusions on a North Carolina State University study that found Gmail allows most emails from Democratic to land in the user’s inbox while more than two-thirds of messages from conservative candidates are marked as spam. [tweet_embed] April 15, 2022[/tweet_embed] Gmail “retained the majority of left-wing candidate emails in inbox (< 10.12% marked as spam) while sent the majority of right-wing candidate emails to the spam folder (up to 77.2% marked as spam),” the study found. “Email services use spam filtering algorithms (SFAs) to filter emails that are unwanted by the user. However, at times, the emails perceived by an SFA as unwanted may be important to the user,” the abstract wrote.

Google’s email suppression – which affects the GOP’s fundraising and GOTV efforts – is another egregious example. Silicon Valley oligarchs are suppressing free political speech.” – RNC Chairwoman Ronna McDaniel, NRSC Chairman Senator Rick Scott, and NRCC Chairman Congressman Tom Emmer said in a joint statement.

Gmail users can move messages to spam, or to any other category,” the Google spokesperson continued. “Gmail automatically adjusts the classifications of particular emails according to these user actions.” [tweet_embed] April 15, 2022[/tweet_embed] Conservative candidates raised $737 million on the Republican fundraising platform WinRed from Gmail users in 2019 and 2020. Because, according to the study, just 32% of fundraising emails were delivered, the Republicans count they missed out on $1.5 billion in contributions during the 2020 election cycle. During the 2021-2022 election cycle, Republicans have raised $249 million from Gmail users. The GOP committees estimate that their candidates have missed out on $529 million in donations due to Gmail’s filtering algorithms.
