Summary
A new working paper says spam filtering at Gmail, Outlook and Yahoo erased about 142,000 first-time Republican donations in 2025 by diverting WinRed-linked fundraising emails.
During a 78-day episode, first-time WinRed donations fell nearly 75% with no comparable ActBlue drop; in a separate Outlook episode, Republican inbox placement plunged from about 88% to 16%, cutting first-time donors 83%.
The researchers found Republican committee inbox placement can swing 30 percentage points across major mailbox providers, underscoring how Google, Microsoft, Yahoo and AOL control a key choke point in small-dollar fundraising.
Ellis and Powell said the data cannot distinguish a technical link-reputation trigger from partisan bias, but they tested 125 placebo dates and found no similar donation collapse in calmer periods.
The report argues providers should disclose when they change treatment of named payment processors or sender classes and allow neutral audits, rather than leaving campaigns to discover filtering shifts only after fundraising damage.
