What are power words in email subject lines?
Power words are the small vocabulary that makes a line feel like it matters: 'secret' opens a curiosity gap, 'deadline' sets a clock, 'proven' borrows evidence, 'your' makes it about the reader. The finder scans your text against all 46 words in five categories and shows each hit with a note — including the double-edged ones most lists won't tell you about: 'save' is both a benefit word and a medium spam trigger; 'secret' is a curiosity classic that reads spammy when stacked; 'double' sells hard but 'double your income' is a textbook scam phrase. Words are tools, and the notes tell you when the tool bites.
Common uses
