Spam filters have changed

Modern spam filters rely heavily on engagement signals rather than keywords. Low engagement can quickly send future emails to spam folders.

Key signals that matter

  • Reply rates
  • Delete without reading
  • Spam complaints
  • Consistency of sending volume

Focus on delivering value and maintaining consistent sending behavior to improve inbox placement.
