✅ Do These Things
- Keep it concise: Aim for 30-50 characters to ensure full visibility on mobile devices
- Create urgency: Use time-sensitive language like "Limited time" or "Expires today"
- Personalize when possible: Include recipient's name or company for higher engagement
- Test different approaches: A/B test subject lines to find what works for your audience
- Use action words: Start with verbs like "Discover," "Get," "Save," or "Learn"
❌ Avoid These Mistakes
- Spam trigger words: Avoid "FREE," "URGENT," excessive caps, or multiple exclamation marks
- Being too vague: Generic subjects like "Newsletter" or "Update" don't create interest
- Misleading content: Don't promise something your email doesn't deliver
- Too many symbols: Excessive use of emojis or special characters can trigger spam filters
- All caps or no caps: Both extremes look unprofessional and hurt deliverability
