Subject Line Best Practices
Keep it Short & Sweet: Aim for 40-50 characters. Most mobile devices will cut off anything longer.
Create Urgency or Curiosity: Use words that prompt immediate action, like "urgent," "breaking," "limited time," or ask an intriguing question.
Personalize When Possible: Including a recipient's name (e.g., using `[FNAME]`) can significantly boost open rates.
Use Numbers and Data: Digits stand out in a crowded inbox. "5 ways to..." is often more effective than "Five ways to...".
Avoid "Spammy" Language: Words like "free," "guarantee," "act now," and excessive use of exclamation marks or ALL CAPS can trigger spam filters.
Use Emojis Sparingly: One or two relevant emojis can add personality and draw attention, but overusing them can look unprofessional or spammy.
