Email open rates live or die by the subject line. This prompt generates two distinct versions of a subject line so you can test which "angle" works better for your audience.

The Core Prompt

Generate 5 pairs of A/B test subject lines for an upcoming "Spring Sale" email. Version A should be "Urgency-focused" (e.g., Ends tonight), and Version B should be "Benefit-focused" (e.g., Get the glow).

Marketing Psychology

Different segments of your audience respond to different triggers. Some are motivated by "Loss Aversion" (Urgency), others by "Self-Improvement" (Benefit).

Usage Tips

  • Emojis: Ask the AI to "include exactly one relevant emoji in each subject line."
  • Character Limit: Specify "under 40 characters" to ensure they don't get cut off on mobile.
