Email Subject Line Best Practices
Follow these tips to write subject lines that get opened:
Optimal Length
Keep your subject lines between 20-50 characters. This ensures they display fully on mobile devices and don't get truncated.
Personalization
Use the recipient's name or company to increase relevance. Personalized subject lines have 26% higher open rates.
Strategic Emoji Use
One relevant emoji can make your email stand out in a crowded inbox, but don't overdo it. Use emojis that match your brand tone.
Avoid Spam Triggers
Stay away from words like 'FREE', 'URGENT', excessive caps, and multiple exclamation marks. These can send your emails to spam.
