Twelve subject lines from twelve different patterns, so you can A/B a question against a number against a plain statement instead of twelve versions of the same idea. Each one is length- and spam-checked.
Click any line to copy it. Green = under 45 characters (shows fully on phones). Amber = long. Red = spam-trigger word — reword before sending.
