Email Subject Line Swipe File

Subject line formulas organised by the email you are actually sending, each with a worked example graded by the same rubric as our free grader.

What you get

• 67 formulas in 12 categories: newsletters, launches, promotions, welcome, re-engagement, abandoned cart, events, B2B outreach, educational, reminders, feedback and transactional.
• Every formula comes with a worked example and its A–F grade and character count, using the emailsubjectgrader.com rubric.
• Before-and-after rewrites, the spam trigger words the rubric penalises, preheader tips and a pre-send checklist.
• A/B test tracker (XLSX) that calculates open and click rates for each version.

Grades are a writing check, not a prediction of your open rate. Results depend on your list, sender reputation and content.
