Your Subject Line Is Your First Impression

How to Write Perfect Subject Lines
Keep it Short
Mobile devices cut off subject lines after 40-60 characters. Aim for 6-8 words max to ensure visibility.
Spark Curiosity
Don’t give everything away. Use questions or teaser statements to make the recipient want to know more.
Avoid Spam Words
Words like “Free,” “Guarantee,” and “Urgent” trigger spam filters. Our tool analyzes this automatically.
