What are myths that no longer apply (e.g., keyword stuffing)?

Several spam filter myths persist from earlier eras but no longer reflect modern reality. Understanding what has changed helps focus on what actually matters.

Keyword avoidance was once critical. Today, context and reputation matter far more than individual words. Write naturally instead of contorting language to avoid "trigger words."

Image-only emails were once thought to evade text scanning. Modern filters analyze images, detect text within them, and penalize the tactic as suspicious.

Font color tricks like white text on white backgrounds are now instantly detected. Filters specifically scan for hidden text as a spam indicator.

Sending time manipulation to hit inboxes at optimal moments does not affect filtering. Filters evaluate content and reputation, not arrival timing.

Yesterday's cleverness is today's red flag. Filters have evolved; your tactics should too.
