Why subject lines matter
Your email content only matters if people open the email. The subject line is the first filter between your message and your audience. A weak subject line can cause even a great email to be ignored.
Strong subject lines usually combine clarity, curiosity, relevance, and urgency. The best option depends on your audience and the goal of the email. That is why generating multiple options and comparing them is often more effective than choosing the first idea.
Use the scores as guidance, not absolute truth. Real performance depends on list quality, sender reputation, timing, and offer strength. Whenever possible, A/B test the top subject lines.
